    Scottish Government (gov.scot)

    SCOTLAND, and it replaces England's Part P competent person scheme, which does not apply in Scotland at all. Published 1 May 2012, third edition, 48 page PDF, 683.6 kB. The handbook governs Scotland's two certification routes under the Building (Scotland) Act 2003: approved certifiers of design, used for structural design and for energy, and approved certifiers of construction, used for electrical installations and for drainage, heating and plumbing. A certificate from an approved certifier is accepted by the verifier as conclusive evidence of compliance for that part of the work, reducing what the verifier checks, but it does not remove the need for a building warrant or for the relevant person to submit the completion certificate. Scheme providers are listed on the certification register at certificationregister.co.uk. Contact is buildingstandards@gov.scot or 0131 244 6511.

    Scottish Government (gov.scot)

    SCOTLAND, and this is where an England-based note goes wrong. A completion certificate confirms the building was constructed, demolished or converted in accordance with the warrant and the building regulations, and it is submitted by the relevant person, usually the owner or developer, not issued unprompted by the authority. It is an offence to submit a completion certificate known to be false, and an offence to occupy a new building, a conversion or an extension unless the completion certificate has been ACCEPTED by the verifier. Temporary occupation or use can be permitted under section 21 of the Act on application to the verifier, who takes account of mitigation such as means of escape in a partially completed building. The occupation bar does not apply to alterations, but a completion certificate for alterations must still be submitted before the warrant expires. Where an approved certifier of construction is involved, the relevant person must still certify completion. Section 9 notes that a local authority may operate a letter of comfort scheme for older unauthorised works, Scotland's practical counterpart to England's regularisation certificate.

    SCOTLAND. The Scottish Government policy page that explains the technical handbooks expand the functional standards set by the Building (Scotland) Regulations 2004, and dates the current edition: new technical handbooks apply from 6 April 2026, amending Section 0 General, Section 2 Fire, Section 3 Environment and Section 4 Safety. Section 0 is updated for the amendment to Regulation 8 and a changed definition of traditionally constructed buildings; Section 2 gives effect to Simon and Richard's Law with extended guidance on conversions of traditional buildings, materials limiting fire spread and escape, and amends Standard 2.15 on automatic fire suppression; Standard 3.3 gains new flooding and groundwater guidance with a flooding annex; and clause 4.1.7 gains advice on letterplate positioning in new dwellings.

    Scottish Government (gov.scot)

    SCOTLAND. Published 25 March 2026, ISBN 9781806439690, in force from 1 April 2026, and it carries the revised table of fees applicable to all building warrant applications, so it is the correct source for what a Scottish building warrant costs. It explains the procedures underpinning the Scottish building standards system as set out in the Building (Procedure) (Scotland) Regulations 2004 and the Building (Scotland) Act 2003. Scotland charges a building warrant fee scaled to the estimated value of the work, a structure with no direct England parallel now that England's building control charges are set locally by each authority or by a private registered building control approver.

  5. very strong RN-VR0Q0L

    Scottish Government (gov.scot)

    SCOTLAND, and this contradicts the England position outright. New-style Scottish EPCs are introduced from 30 April 2028 under the Energy Performance of Buildings (Scotland) Regulations 2025, replacing the 2008 regulations. Domestic EPCs will show separate ratings for heat retention, heating system and energy costs, non-domestic ones for energy performance, energy use and direct emissions, and certificates will be valid for 5 years rather than 10, so the familiar ten-year EPC validity will not hold in Scotland. Between 30 April 2028 and 30 April 2029 a sale or let may use either an old-style EPC and recommendations report or a new-style EPC and property report, but a property sold or let a second time inside that window must have the new-style pair; from 30 April 2029 only new-style certificates are valid. Assessors can issue only new-style EPCs from 30 April 2028. The same one-year grace period applies to Scotland's roughly 30,000 short-term lets. Dates remain subject to Scottish Parliament approval.

  6. very strong RN-QT7ZA7

    Scottish Government (gov.scot)

    SCOTLAND, last updated 24 August 2026. Confirms the EPC in Scotland is administered separately from England and Wales: buildings are rated A to G with A most efficient, the certificate lists improvement measures with an indicative cost for each, and it is accompanied by a recommendations report. The assessment reflects the building not the occupants, using standard assumptions about occupancy and use, and carries no personal data other than the assessor's name and contact details. For non-domestic buildings the EPC shows an asset rating alongside primary energy use. The page states that EPCs in Scotland are being reformed by the Energy Performance of Buildings (Scotland) Regulations 2025, replacing the 2008 regulations, with new-style certificates and strengthened quality assurance. Enquiries go to EPCenquiries@gov.scot, not to an England service.

  7. very strong RN-ONL4C3

    Scottish Government (mygov.scot)

    SCOTLAND, last updated 24 November 2025. Scotland has no building notice or full plans choice and no private registered building control approvers: a building warrant must be obtained from the local council's building standards department BEFORE work starts, and starting work without one when required is an offence punishable by a fine. A warrant is needed for building a new home, extending a home, building or removing load-bearing walls, changing roofs, external walls or other structural elements, converting a loft or garage into a room, and demolition. Applications go through the eDevelopment portal, and the page lists all 32 Scottish councils plus their building standards departments as the verifiers. This directly contradicts an England-based note that offers a retrospective regularisation route or a choice of approved inspector.

  8. very strong RN-6R7416

    The National Archives (legislation.gov.uk)

    Section 80 requires anyone intending to demolish a building to give notice to the local authority, specifying the building and the works, with copies to adjoining occupiers and the gas and electricity suppliers. It does not apply to buildings of not more than 1,750 cubic feet by external measurement, to greenhouses, conservatories, sheds or prefabricated garages forming part of a larger building, to internal parts of an occupied building that will stay occupied, or to agricultural buildings. Breach is a summary offence carrying a fine up to level 4 on the standard scale.

    The National Archives (legislation.gov.uk)

    Sets out exactly what a declaration of performance must contain, which is what to look for when checking a product claim. Article 6(2) requires the product-type reference, the system or systems of assessment and verification of constancy of performance from Annex V, the reference number and date of issue of the designated standard or UK Technical Assessment used for each essential characteristic, and any Specific Technical Documentation reference. Article 6(3) requires the intended use or uses, the list of essential characteristics, the performance of at least one essential characteristic, performance stated by level, class or description, and crucially that any listed essential characteristic for which no performance is declared must carry the letters NPD, meaning No Performance Determined. Article 6(4) requires the declaration to follow the model in Annex III.

  10. very strong RN-YU2I7R

    The National Archives (legislation.gov.uk)

    The Act (2015 c. 17) that created the Right to Build. Section 1 requires relevant authorities to keep registers of people seeking to acquire serviced plots to build their own home; section 2 imposes duties in relation to those registers; sections 2A and 2B (inserted later) set the duty to grant enough planning permissions to match demand and the exemptions. The Schedule covers eligibility, applications, review rights and fees for the registers.

  11. very strong RN-HSIYH3

    The National Archives (legislation.gov.uk)

    The instrument that rewrote Part R of Schedule 1 to add the gigabit duties, in force on 26 December 2022 and applying in England. Its Schedule Part 1 renames the heading to Part 9A as "Infrastructure for electronic communications", inserts new exemptions before regulation 44A, amends regulation 44C (the interpretation provision that defines major renovation works), amends regulation 55 (review of Part 9A and Part R), and substitutes Part R of Schedule 1 so that the old single requirement R1 is joined by requirements RA1 (gigabit-ready physical infrastructure) and RA2 (connection to a gigabit-capable network) for new dwellings. It also amends regulations 13 and 14 of the Building Regulations 2010, on the particulars accompanying a building notice and full plans, so the connectivity plan must be submitted, and amends Schedule 1 to the Building (Approved Inspectors etc.) Regulations 2010 to match. A correction slip was issued on 22 November 2022. This is the source that dates the split between Approved Document R Volume 1 (new dwellings) and Volume 2 (other buildings and major renovation works).

    UK Health Security Agency

    UKHSA's cold weather health guidance, first published 2 November 2012 and last updated 28 April 2026, applying to England, reference GOV-15292. Establishes the alerting framework a heating or insulation note can anchor to: the UKHSA Cold-Health Alerting system is operated by the Met Office and runs from 1 November to 31 March each year, and this guidance forms the cold weather part of UKHSA's Adverse Weather and Health Plan, whose aim is to protect health and reduce harm from adverse cold weather. Issued in several formats including an HTML main version, an easy read PDF of 8 pages, a British Sign Language video, a two-page print version of top tips, and a poster, with easy-read translations added on 28 April 2026 in Arabic, Bengali, Gujarati, Hindi, Italian, Kutchi, Punjabi, Portuguese, Somali, Tamil and Urdu.

  13. very strong RN-6PQK9U

    UK Health Security Agency (UKradon)

    UKHSA recommends that radon levels be reduced in homes where the average exceeds 200 becquerels per cubic metre, the Action Level, and states that this recommendation is endorsed by Government. The Action Level refers to the annual average concentration, so a valid measurement uses two detectors, one in a bedroom and one in a living room, left in place for three months to average out short-term fluctuations. Separately defines a Target Level of 100 Bq per cubic metre as the ideal outcome of remediation in existing buildings and of protective measures in new buildings, and advises that where a result falls between the Target and Action Levels action to reduce the level should still be considered, especially where a smoker or ex-smoker lives in the home. Radon is described as a colourless, odourless radioactive gas formed by decay of naturally occurring uranium in rocks and soils.

  14. very strong RN-DK9G2M

    Valuation Office Agency (HM Revenue & Customs)

    VOA guidance (published 28 October 2024, updated 7 October 2025) on when a home can be deleted from the Council Tax list during works. Deletion is possible for fully demolished properties, truly derelict properties needing structural reconstruction, and major renovations where significant redevelopment affects most of the property; planning permission alone does not count as work starting. Poor repair (redecoration, minor plaster or ceiling repairs, replacement windows) does not qualify, and an occupied property must always keep a band. Approved deletions are backdated.

  15. very strong RN-MZWVT0

    Valuation Office Agency, HMRC (GOV.UK)

    Published 22 January 2016 and last updated 15 June 2026, applying to England and Wales, this is the authority that corrects two common claims. First, on rebanding after an improvement: bands are based on the open market price on 1 April 1991 in England and 1 April 2003 in Wales, and if a property has increased in size since it was first assessed it may move to a higher band when it is next sold, so an extension does not trigger an immediate rebanding of the current owner. Second, on Council Tax during works: if the property is occupied the band will not be deleted even if significant repair or renovation works are underway, and only where the property is unoccupied and either beyond repair or undergoing major works making it uninhabitable can the owner apply to have the band removed. Reproduces the full band tables: England Band A up to 40,000 pounds through Band H over 320,000 pounds; Wales Band A up to 44,000 pounds through Band I over 424,000 pounds, Wales having nine bands to England's eight. Assessments are based on size, layout, character, location, change of use and the 1991 or 2003 value, and the Valuation Office does not use property price indexes.

    Welsh Government

    The Welsh route to funded adaptations, which differs from England in having a second scheme alongside the Disabled Facilities Grant. A Welsh applicant can apply for support from one or more of the ENABLE support for living independently scheme and the Disabled Facilities Grant, whereas an English applicant has the Disabled Facilities Grant alone. The listed adaptations are widening doors and installing ramps, improving access to rooms and facilities such as stair lifts or a downstairs bathroom, providing a heating system suitable for the applicant's needs, and adapting heating or lighting controls to make them easier to use. Part of the Welsh Government's Home safety, repairs and adaptation collection, with parallel guides for social housing tenants and for adapting a home before returning from hospital.

    WALES. A Welsh Government collection of quick guides, first published 27 October 2017 and last updated 22 March 2023, saying for each common project whether building regulations approval is needed in Wales. It covers adverts and signs, basements, biomass fuelled appliances, boilers and heating, ceilings and floors, change of use, conservatories, decking, decorations, demolition, doors and windows, drains and sewers, electrics, extensions, external walls, fascias, fences gates and garden walls, flats and maisonettes, flues, fuel tanks, garage conversion, heat pumps, hydro electricity, insulation, internal walls, kitchens and bathrooms, lighting, loft conversions, micro combined heat and power, outbuildings, patio and driveway and paving your front garden.

    Welsh Government (gov.wales)

    WALES. Published 18 June 2026. New building regulations come into force in Wales on 1 JULY 2026, a different commencement from England's building control reforms, made by the Building (Higher-Risk Buildings Procedures) (Wales) Regulations 2025 and the Building etc. (Amendment) (No. 2) (Wales) Regulations 2025. The first introduces a requirement for approval before higher-risk building work can begin, known as Gateway 2, a building control approval application process, change control and mandatory reporting of safety issues during the work, a completion approval process known as Gateway 3, the golden thread of information, appeal procedures and transitional arrangements. The second sets roles, responsibilities and requirements for dutyholders involved in any controlled building work, so it reaches ordinary domestic projects and not only higher-risk buildings.

  19. very strong RN-C01OHV

    Welsh Revenue Authority

    Land Transaction Tax replaced Stamp Duty Land Tax in Wales from 1 April 2018 and is collected and managed by the Welsh Revenue Authority for the Welsh Government. First published 21 September 2017 and last updated 25 November 2024. The current LTT threshold is 225,000 pounds for residential properties where the buyer does not own other property, and 225,000 pounds for non-residential land and property. The correction most often needed: there is no first-time buyers' relief in Wales, unlike England and Northern Ireland. Higher residential rates apply where the buyer already owns one or more residential properties, though not normally where they are replacing a main residence. LTT is a self-assessed tax and a return must be sent even where there is nothing to pay, except for certain transactions that need no return. Specific reliefs exist for multiple dwellings, group structures and charities. Since 3 July 2023 solicitors and conveyancers can only file LTT online, and the WRA publishes a postcode checker to establish whether a property is in Wales.

    BBA (British Board of Agrement)

    The certification body whose Agrement Certificate is what a note usually means when it says a system is approved, and the page that lists which schemes it actually runs. The BBA's certification team issues certificates for the BBA Agrement, HAPAS (Highways Authority Product Approval Services), European Technical Assessment (ETA), and the Microgeneration Certification Scheme. Alongside product certification it runs certification of people, including the BBA Approved Installer Scheme, the BBA Competent Person Scheme, the BBA Gas Membrane Approved Installer Scheme, TrustMark registration and the BBA PAS 2030 Scheme, plus a Client Managed Inspection Service. Its testing services are also available standalone and include durability, mechanical, physical and structural, weather resistance and wind serviceability, conformance and fit-for-purpose, thermal performance, and onsite testing and trials. An Agrement Certificate is the route by which a product without a harmonised European product standard, such as a tanking membrane, a multifoil or a proprietary EWI system, gets an independently assessed statement of fitness for a stated use.

    BRE Group

    Important currency point for any note mentioning certification schemes: the Home Quality Mark no longer exists under that name. BRE has folded it into the BREEAM product range as BREEAM UK New Construction: Residential, with version 6.1 released in April 2025. HQM led residential sustainability assessment in the UK from 2015 with more than 50,000 homes registered. The scheme assesses homes against three sustainability indicators covering environmental performance (carbon emissions, resource efficiency, biodiversity, circular design), social performance (occupant health and wellbeing, indoor air quality, daylight, thermal comfort, noise, access to green space) and economic performance (efficient use of materials, future-ready infrastructure, running costs, adaptability). Homes are rated on a scale from pass to outstanding. BRE states the certification recognises performance BEYOND minimum regulations only, and that certification can open access to green mortgages and investment incentives. Separately, BREEAM Refurbishment and Fit-Out (currently V7) is the BREEAM standard covering refurbishment rather than new build, and BREEAM has run third-party certified standards since 1990.

    BSI Group

    What the Kitemark actually certifies, which matters because it is often confused with CE or UKCA marking and with BSI standards themselves. States that Kitemark certification confirms a product or service's claim has been independently and repeatedly tested by experts, so it is third-party certification of continued conformity rather than a manufacturer's own declaration. Records that the mark was originally known as the British Standard Mark and was first registered as a trademark in June 1903, giving it more than 120 years of use. Cites BSI's own consumer research that the Kitemark is recognised by 67 per cent of UK consumers, and that 70 per cent are more confident in products carrying it than in products that do not. Certification spans products, services and processes, including building information modelling and inclusive service certification, and BSI publishes a searchable Kitemark directory and a Verify a Certificate service for checking a specific certificate.

    Financial Conduct Authority

    The register to check before accepting finance arranged by a builder, showroom or installer. Confirms that in the UK almost all financial firms must be authorised or registered by the FCA, and that the tool shows both whether a firm is authorised and whether it has permission to provide the specific services being offered. Sets out the tool's limits candidly: it cannot confirm whether Financial Services Compensation Scheme or Financial Ombudsman Service protection will apply, it omits products and services offered only to other firms, published crypto restrictions, historic fines, the right to approve financial promotions and the ability to handle client money, all of which sit on the fuller Financial Services Register along with information on individuals. Notes that certain financial products are not regulated at all and so do not appear, that updates take on average 24 hours, and that some information is supplied by firms so accuracy is not guaranteed.

    Financial Conduct Authority

    The regulator's 2026 multi-firm review of the product most often sold as a home improvement loan, published 12 March 2026 and updated 13 March 2026. Establishes the market facts a finance note should cite: second charge mortgages let a homeowner borrow against equity without changing their main mortgage, they are typically less than 4 per cent of regulated mortgage sales, they tend to carry higher interest rates than first charge mortgages, and consumers mostly use them to consolidate debt rather than to fund works. Warns that these customers often carry a high level of debt so a significant proportion may have characteristics of vulnerability including low financial resilience. The FCA reviewed quality of advice, robustness of affordability assessments, the role of intermediaries, record keeping and intermediary fees, sampling firms covering over 40 per cent of second charge advice firms and around 50 per cent of second charge lenders, and found evidence of poor practices creating a risk of poor customer outcomes. Frames expectations against the Consumer Duty and the Mortgage Conduct of Business rules, and follows a 2018 Dear CEO letter to second charge lenders and a 2025 Portfolio Letter to mortgage intermediaries.

  26. strong RN-S3JMRF

    MCS (Microgeneration Certification Scheme)

    How the standards behind MCS certification are set and changed, which matters because MCS certification is a precondition of the main heat pump and solar grants. MCS Standards are owned by the MCS Foundation and governed by the MCS Approval Committee, chaired by the Independent Chair of Standards, David Heath, whose role is to oversee the Technical Working Groups and protect the integrity and impartiality of the Standards. The Approval Committee ensures changes adhere to governance processes and, depending on the type of change, incorporate industry and technical expert feedback through public consultation. Technical Working Groups develop the Standards and many members sit on European committees, keeping MCS aligned with current EN Standards. Two published change processes govern updates: the Technical Document Control Process, reference 455010, for MCS Technical Standards, and the Scheme Document Control Process, reference 184199, for MCS Scheme documents.

  27. strong RN-YSGE59

    NAPIT

    Useful for untangling the terms consumers meet on certification schemes. Distinguishes authorisation, accreditation, certification and registration: NAPIT Registration is authorised by government to operate Competent Person Schemes supporting self-certification against the Building Regulations in England and Wales, with the current scope of that authorisation published on the Government website, while NAPIT Certification is separately accredited by the United Kingdom Accreditation Service, with the schedule of accreditation published on the UKAS website. Explains that a scheme member is normally both registered, meaning listed on a searchable register, and certificated, meaning holding a certificate within the scope of a particular scheme, and that the search facility verifies certification status. Warns that not all work carried out by members is covered by the scheme scope.

  28. strong RN-GFUBDV

    Royal Institution of Chartered Surveyors

    The main built-environment alternative dispute resolution provider a homeowner is likely to meet, useful because statutory adjudication under the Housing Grants, Construction and Regeneration Act 1996 does not apply to contracts with a residential occupier, so a homeowner needs a contractual or voluntary route instead. RICS DRS supplies impartial ADR across the property, construction and land sectors as an alternative to litigation, states it has over 40 years of experience and has handled cases worth billions globally, and selects and assesses each panel member for expertise, impartiality and professionalism. Publishes downloadable application forms per service, a searchable panel, and a Conflict Avoidance Process which produces a report with reasoned but non-binding recommendations, intended to head off a dispute before it becomes one. Also runs ADR education through diplomas and distance and face to face programmes.

  30. strong RN-RBTGMH

    Royal Institution of Chartered Surveyors

    The mandatory standard a UK valuer works to, and the right citation whenever a note distinguishes a survey from a valuation. The Red Book UK national supplement sets specific requirements for applying the RICS Valuation Global Standards to valuations undertaken subject to UK jurisdiction; it was published on 19 October 2023 and came into effect on 1 May 2024, applying to all valuations with a valuation date on or after that. Its references were updated following the updated RICS Valuation Global Standards effective 31 January 2025. RICS defines subject to UK jurisdiction as where performance of the valuation contract is subject to UK statutes, rules and regulations, also considering the jurisdiction in which a claim about the valuation could be brought; the Isle of Man, Jersey, Guernsey and the Republic of Ireland are not part of the UK. The update was made to implement valuation governance amendments from the Valuation Review plus technical updates to public sector, financial reporting and residential content, including a new rotation policy for some regulated purpose valuations. One correction a note should carry: RICS states there is NO new residential mortgage specification. Residential mortgage valuation advice previously sat in VPGA 11 (effective 2019) and before that Appendix 10 of the 2014 edition updated April 2015; the newly updated VPGA 11 sets only high level principles for residential valuation and does not go into significant detail on residential mortgages, and RICS is separately developing a new UK professional standard for the valuation of residential property for owner occupation.

    The landing page for the Red Book, the publication that details MANDATORY practices for RICS members undertaking valuation services and serves as a reference for valuation users. The page confirms the current edition, RICS Valuation Global Standards, became effective on 31 January 2025, and that the Red Book sits on top of the International Valuation Standards (IVS), which are the key global guidance for valuation professionals, with the Red Book UK national supplement applying the Global Standards to UK jurisdiction valuations. Use it to make the point that a Red Book valuation is a regulated, mandatory-standard product distinct from an RICS Home Survey, which is governed instead by the Home Survey Standard, even though a Home Survey Level 2 can be bought in a survey and valuation version.

    United Kingdom Accreditation Service

    Establishes that UKAS is the sole National Accreditation Body for the United Kingdom, appointed under the UK Accreditation Regulations 2009 for the purposes of Article 4(1) of Regulation (EC) 765/2008 as it has effect in Great Britain. Explains that accreditation assesses the competence, impartiality and performance capability of conformity assessment bodies that provide certification, testing, inspection, calibration and verification, summarised as UKAS checking the checkers. It is Government policy to recommend UKAS accredited conformity assessment services wherever that is an option, and UK conformity assessment bodies seeking accreditation must obtain it from UKAS. UKAS is independent of Government, a non-profit-distributing company limited by guarantee, operating under a Memorandum of Understanding with the Secretary of State for Business and Trade, which licenses its use of the national accreditation symbols.

    United Kingdom Accreditation Service

    UKAS explains what each sanction means in practice. A suspension is normally temporary, with the body expected to regain accreditation within three months and up to nine in exceptional circumstances. While suspended an organisation cannot provide accredited services, cannot issue new accredited certificates, and must tell existing and prospective customers of its status. Certificates issued before the suspension remain valid unless they were issued incorrectly, though annual surveillance or renewal visits falling inside the suspension period may not be supportable.

    AECB (Association for Environment Conscious Building)

    The AECB CarbonLite family, the main UK alternative to Passivhaus for a homeowner who wants a measurable low-energy target rather than minimum Building Regulations compliance. The page names four standards and three supporting guidance documents: CarbonLite New Build for new domestic and non-domestic projects; CarbonLite Retrofit for individual or multifamily homes and non-domestic buildings; CarbonLite Retrofit Step-by-Step, designed principally for retrofitting individual or multifamily homes in stages rather than in one go; and the Water Standard for water efficiency in domestic and non-domestic projects, plus Daylighting design guidance (with an AECB CarbonLite software tool) and Airtightness guidance. Each standard has its own detailed guidance PDF. Two facts worth citing: AECB set up the Passivhaus Trust in 2010, so the two bodies are related rather than rivals, and AECB CarbonLite certified homes qualify for Ecology Building Society C-Change mortgage discounts of up to 1.50 percent off the standard variable rate, applied for the lifetime of the mortgage on completion of the project, which is a rare concrete financial consequence of a voluntary standard.

    BSRIA (Building Services Research and Information Association)

    BSRIA is UKAS accredited for airtightness testing and this page sets out what a test involves and when it is required, which is the practical detail behind a Part L conversation. It confirms BSRIA is an ATTMA member, UKAS accredited to test to CIBSE TM23, BS EN 13829 and ATTMA TS L1, and that its certificates are recognised by building control. On when testing bites: the page states airtightness testing of new dwellings is mandatory for developments of over two units, that a sample of each dwelling type must be tested and must fall within the air leakage rate stated in that dwelling SAP calculation, and that for developments of one or two units testing is not mandatory but an assumed air leakage rate above the industry norm must be used instead, so it is usually simpler and cheaper for a builder to test and prove a lower rate. It also lists the information needed to plan a test regime: SAP calculation worksheets, floor plans and sections for each dwelling, the regulation or standard being met, site layout and build programme. Diagnostics offered on a failure include infrared thermography and smoke tests to find leakage paths. Note the page still uses the pre-2021 label Part L1A alongside Section 6 of the Scottish Building Standards, so check the current Approved Document L Volume 1 wording before quoting the sampling rule as current.

    CIRIA (Construction Industry Research and Information Association)

    The UK code of practice for making an existing home resistant to and recoverable from flooding, and free to download after sign-in, which makes it unusually accessible for a CIRIA title. The C790 project produced four outputs a note can name separately: C790A, the Code of practice for property flood resilience, Edition 2, which sets six standards specifying what should be achieved; C790B, Guidance on the code of practice, explaining how each of the six standards should be met across the stages of a property flood resilience delivery process; C790C, Making your property more flood resilient, written for households and businesses; and C790D, Guidance for local authority planners. The code draws the distinction a renovation note should use: resistance measures reduce the amount of water entering a building, and recoverability measures limit the damage caused once water is inside, with the aim of reducing damage and speeding up recovery and reoccupation.

    Considerate Constructors Scheme

    The code a registered contractor commits to, and the standard a homeowner or neighbour can measure a builder against. Registering an organisation, contractor or supplier with the Scheme is a commitment to observe and implement the Code, and the Code applies equally to all registered activities regardless of size, type or location. It has three sections. Respect the community: courteous and respectful language and appropriate behaviour in and around the activity; providing a safer environment, preventing unnecessary disturbance and reducing nuisance for the community; and proactively maintaining effective community engagement. Care for the environment: prioritising environmental issues to protect the natural environment and minimise negative impacts; optimising the use of resources including minimising carbon throughout the value chain; and engaging with the community to improve the local environment. Value the workforce: creating a supportive, inclusive and healthy workplace. Registration also means agreeing to be visited and scored by a Scheme Monitor, with conformance recognised through Certificates of Performance, Records of Performance and the Leading Lights Awards, and optional paid advisory visits available.

    Federation of Master Builders

    The FMB's searchable directory of member builders by trade and location, which the FMB describes as the only way to find inspected builders in the UK, with members vetted, inspected and monitored. Provides a 'check a member' lookup specifically because some firms claim FMB membership without holding it. Advises homeowners to do their own research on planning permission, building regulations, party walls and alterations to listed buildings rather than relying on the builder, and links its own guides on choosing a builder, working with a builder, loft conversions, garage conversions, bathrooms, kitchens and house extensions. Carries a formal complaints procedure and CTSI-certified alternative dispute resolution.

    Passivhaus Trust

    The UK body page for the Passivhaus standard, and the right citation for a note explaining low-energy standards above Building Regulations. It confirms EnerPHit is the separate, slightly relaxed Passive House Institute standard for RETROFIT projects, used where existing architecture and conservation constraints make full Passivhaus infeasible, which is the distinction most renovation articles blur. The Trust defines eight Passivhaus principles: the five building principles of insulation, airtightness, ventilation, minimised thermal bridging and high-performance windows, plus three principles of approach, namely detailed performance and comfort criteria, accurate design modelling using the Passive House Planning Package (PHPP), and rigorous quality assurance. It states the UK performance gap between designed and in-use energy conservatively results in a 60% increase in space heating demand in residential buildings, and often considerably more in non-residential, whereas Passivhaus buildings on average perform as designed. On claims: a building may reasonably be called a self-declared Passivhaus provided it satisfies all requirements of the standard, but certification must be by a registered Passivhaus Certifier independent of the design team. Caution when citing numbers: the headline criteria table on this page is published as an image and linked PDF rather than as text, so the numeric targets must be taken from the Passive House Institute criteria document itself.

    TrustMark

    What a TrustMark registration is actually worth financially, which is the practical difference between it and an unaccredited trader. Under the TrustMark Framework Operating Requirements every Registered Business is expected to provide a minimum of two years of financial protection for completed works in and around the home, covering product warranties and workmanship. The stated purpose is to cover the homeowner if the business ceases trading for any reason, and TrustMark expects the coverage to extend to four things: prepayments such as deposits or other money paid in advance of work, two years post completion of workmanship, rectification of defects or non-compliance with Building Regulations, and major damage or injury through public liability insurance. Cover varies between businesses depending on their financial protection provider, and TrustMark advises obtaining the details of the specific cover from the business before contracting, and satisfying yourself that it covers the particular products or systems being installed.
