The statutory figures behind a damp diagnosis, and the numbers to quote when a note explains why ground levels or a bridged damp proof course cause rising damp. Paragraph 5.2 requires that in an external wall the damp-proof course should be at least 150mm above the level of the adjoining ground (Diagram 8) unless part of the building protects the wall, and that in an external cavity wall the cavity should be taken down at least 225mm below the level of the lowest damp-proof course, or a damp-proof tray provided (Diagram 9a). For suspended timber ground floors it requires a ventilated air space of at least 75mm from the ground covering to the underside of any wall-plates and at least 150mm to the underside of the suspended timber floor or insulation, with ventilation openings on two opposing external walls of not less than 1,500mm2 per metre run of external wall or 500mm2 per square metre of floor area, whichever is greater; for suspended concrete floors the clear ventilated space is at least 150mm with the same opening sizes. Section 2.39 onwards covers radon, referring to BRE Report BR 211 for protective measures. The 2013 edition was published on 3 September 2013 with changes in effect from 1 October 2013.

The remediation funding route, and the reason a cladding note must separate a house from a block of flats. The scheme applies to buildings 11 metres and above, measured from the lowest external ground level to the finished floor level of the top occupied storey, excluding plant rooms and non-residential facilities such as storage or gyms; separate new funding covers buildings under 11 metres. Homes England administers applications through the Building Remediation Hub. It funds reasonable eligible costs for works addressing life safety fire risks in cladding and external wall systems, covering removal and replacement, access and scaffolding, professional fees, managing agents' fees and Fire Risk Appraisal costs, but not general maintenance, window replacement, insurance premiums or the running costs of interim measures. Applications come from the Responsible Entity, usually the freeholder, head leaseholder, registered provider or management company, and leaseholders cannot apply directly. A Fire Risk Appraisal of External Walls by a certified assessor using PAS 9980:2022 is required. The Building Safety Act 2022 protects qualifying leaseholders from cladding remediation costs. The scheme launched July 2023, the FRAEW panel requirement began 1 November 2023, works are eligible from 10 January 2022, and the social sector expansion took effect 11 June 2025.

Planning Portal
The permission question a cladding or render note must answer. Outside protected areas, cladding is permitted development where the materials are of a similar appearance to those used in the construction of the house. Planning permission is required before cladding the outside of a house with stone, artificial stone, pebble dash, render, timber, plastic or tiles in a conservation area, a National Park, an Area of Outstanding Natural Beauty or the Broads. A listed building needs listed building consent for any significant works, internal or external. No permission is needed for repairs, maintenance or minor improvements such as painting the house. Building Regulations approval is a separate matter, with guidance covering fire protection, thermal resistance, weather resistance and structural loading, and the Planning Portal advises checking with the local planning authority because additional local rules may apply.

Scotland's U-value backstops, which differ from England's Approved Document L and are the numbers to quote for a Scottish reader. Table 6.3 for new dwellings gives area-weighted average maximum U-values in W/m2K of wall 0.22, floor 0.18, roof 0.15, windows, doors and rooflights 1.6, and cavity separating wall 0.2, with individual element values of 0.70 for wall and floor, 0.35 for roof and 3.3 for windows, doors and rooflights. A cavity separating wall can be assigned 0.2 where the cavity has effective perimeter sealing around all exposed edges in line with the insulation layers of abutting elements, and 0.0 where the cavity is also fully filled with a material limiting air movement. Table 6.5 for extensions and conversions is two-column: where the existing dwelling's wall and roof U-values are poorer than 0.7 and 0.25 respectively, wall 0.17, floor 0.15, pitched roof with insulation between ceiling ties or collars 0.11, flat or pitched roof with insulation between rafters or integral 0.13 and windows, doors and rooflights 1.4; where those parameters do not apply the figures relax to 0.22, 0.18, 0.15, 0.18 and 1.6, with individual element values of 0.70, 0.70, 0.35, 0.35 and 3.3. Localised poorer areas such as a meter box must be compensated by the rest of the element and are important for condensation control, while repeating thermal bridges such as timber studs are not treated as individual elements because they are already in the BS EN ISO 6946 calculation.

The regulation behind the combustible cladding ban. Regulation 7(2) requires materials in the external walls or specified attachments of a relevant building to achieve European Classification A2-s1, d0 or A1 for reaction to fire, and regulation 7(1A) prohibits relevant metal composite materials in external walls. Regulation 7(4) defines a relevant building as one with a storey at least 18 metres above ground level, excluding roof-top plant areas and storeys consisting only of plant rooms, containing one or more dwellings, an institution, or a room for residential purposes. Regulation 7(3) lists the exempt components: cavity trays between masonry leaves, parts of roofs connected to external walls, door frames and doors, electrical installations, fibre optic cables, insulation and waterproofing below ground or up to 300mm above it, intumescent and fire-stopping materials, membranes, seals, gaskets, fixings, sealants and backer rods, solar shading device components other than the primary shade element, thermal break materials used for Part L compliance, window frames and glass, and balcony floor layers classified A1fl or A2fl-s1 over an imperforate substrate.

The amendment that tightened the England combustible cladding ban, made under sections 1 and Schedule 1 of the Building Act 1984 and in force on 1 December 2022, extending to England and Wales but expressly not applying to any building in Wales. It inserts the definitions that decide the ban's reach. Reaction to fire classification is fixed as BS EN 13501-1:2018 published by BSI in 2019. Relevant metal composite material means any panel or sheet no more than 10 mm thick comprised of layers, two or more of metal, alloy or metal compound, and one or more substantial layer of a material with a gross calorific value of more than 35 MJ/kg tested to BS EN ISO 1716:2018, with a substantial layer defined as at least 1 mm thick or at least 1 kg per square metre. Specified attachment means a balcony attached to an external wall, a solar shading device other than one attached at a height of no more than 4.5 metres above ground level, or a solar panel attached to an external wall. It also lowers the material change of use trigger in regulation 6(1)(c) from fifteen to eleven metres, and substitutes regulation 6(3) so that on a material change of use under regulation 5(k) the external wall and specified attachments must contain only Class A2-s1, d0 or A1 materials. Regulation 7(2) is substituted in the same terms.

The standard that produces the Euroclass letter, and the one regulation 7(2) of the Building Regulations names by title and ISBN when it requires external wall materials on a relevant building to be Class A2-s1, d0 or A1. Published 31 Jan 2019 and Current. Part 1 provides the reaction to fire classification procedure for all construction products, including products incorporated within building elements, with the sole exception of power, control and communication cables which are classified under EN 13501-6. Products are considered in relation to their end-use application, which is why an insulation board or cladding panel cannot carry a meaningful Euroclass in the abstract: the classification attaches to the product as used in a stated build-up. This is the reference for reading the suffixes as well as the letter, s for smoke production and d for flaming droplets.

The standard behind a correct render specification, published 31 March 2016 and current but under review. It sets requirements and recommendations for the design, preparation and application of renders based on cement, lime or other mineral binders and combinations of them, masonry cement, polymer modified binder based renders, and renders with organic binders. It covers rendering on both new and old backgrounds and the maintenance and non-structural repair of existing work, and gives guidance on site-made, factory-made and semi-finished factory-made renders, including material requirements for reinforcement, carriers and beads and for screws, plugs and anchor fixings, and the background characteristics that govern the design of a rendering system. It explicitly excludes external thermal insulation composite systems (ETICS), gypsum-based external renders, historic monument rendering, concrete structural repair, liquid-retaining structures, sealant specification and flashing design, which is worth noting because EWI render is covered elsewhere.

The product standard for bagged render and plaster, the one a monocouche, silicone or Tyrolean render should be declared to. Published 30 Nov 2016, Current, with Designated status for UKCA marking. Part 1 of the BS EN 998 series applies to factory made rendering and plastering mortars based on inorganic binders for external rendering and internal plastering on walls, ceilings, columns and partitions, and contains definitions, final performance requirements, the assessment and verification of constancy of performance regime and the marking requirements. The binder boundary is spelt out: a calcium sulphate binder may be used as an additional binder with air lime, and if air lime is the principal active binding component the mortar is covered here, but if calcium sulphate is the principal binder it falls under EN 13279 instead. Three exclusions matter on site: site-made rendering and plastering mortars are outside its scope and are covered by codes of application and national specifications; mortars with calcium sulphate as principal binder are excluded; and special fire-resistant and acoustic mortars, structural repair mortars, smoothing and trueing materials, paints, coatings, thin-layer organic renders and prefabricated units such as plasterboard are not dealt with.

Solid wall insulation costs and the quality problem. Typical installation £12,000 to £15,000, split as around £15,000 for external wall insulation and around £12,000 for internal. Around 33% of the heat lost from an uninsulated home goes through the walls. Homes built before 1920 are more likely to have solid walls, of brick, stone, earth or timber frame with panels. A registered installer should guarantee the work for 25 years, and any TrustMark solid wall insulation company offers a 25 year guarantee backed either by an insurer or through the Solid Wall Insulation Guarantee Agency. Records that in October 2025 the National Audit Office reported on quality failures in wall insulation under government schemes, and that 98% of homes fitted with external wall insulation under ECO4 and the Great British Insulation Scheme have problems needing fixing, with affected households sent an Ofgem letter carrying a Unique Measure Reference Number in early 2026 and a remediation line on 0333 555 1234 option 1.
