Northern Ireland's Part L guidance, October 2012, and the clearest published table on how much permanent ventilation a gas cooker needs. Table 4.1 sets the ventilation for flueless gas appliances. For a cooker, oven, hotplate or grill or any combination of them, with no maximum rated heat input: a room, space or internal space under 5 cubic metres needs a permanently open air vent of 10,000 square millimetres free area; 5 to 10 cubic metres needs 5,000 square millimetres, and none at all if the room has a door opening directly outside; over 10 cubic metres needs no permanently open vent. A flueless instantaneous water heater may not be installed at all in a room under 5 cubic metres, needs 10,000 square millimetres from 5 to 10 cubic metres and 5,000 square millimetres over 10 up to 20 cubic metres. Flueless space heaters are limited to 0.045 kW net per cubic metre of room volume, or 0.090 kW net per cubic metre in an internal space such as a hallway or landing. Note 5 makes clear these permanent vents are additional to the openable elements and, for kitchens, the extract ventilation required by Part K. Regulation 54 onwards also covers hearths, flue and chimney design and the durable notice plate required when a hearth, fireplace, flue or chimney is provided or extended.

Northern Ireland's ventilation guidance, the devolved counterpart to Approved Document F, and a clean source for extract rates because its Table 2.1 sets them out room by room. Intermittent extract minimum rates: kitchen 30 litres per second adjacent to the hob or 60 litres per second elsewhere, utility room 30 litres per second, bathroom 15 litres per second, sanitary accommodation 6 litres per second. Continuous extract minimum high rates: kitchen 13 litres per second, utility room 8, bathroom 8, sanitary accommodation 6. The whole-dwelling ventilation rate should not be less than 0.3 litres per second per square metre of internal floor area, and where a greater level of occupancy is expected an extra 4 litres per second per occupant should be added. It describes System 1, background ventilators with intermittent extract fans, as the common domestic strategy. The 30 versus 60 litres per second split is the figure that decides whether a cooker hood can sit above the hob or must be sized up when placed away from it, for example over an island.

Health and Safety Executive
The figure that governs any dry cutting of a quartz or engineered stone worktop, and the one a fabricator should be asked about. INDG463, published 05/24. The Workplace Exposure Limit for respirable crystalline silica is 0.1 mg per cubic metre of respirable dust averaged over 8 hours, and control measures must be effective in keeping exposure below it. The leaflet tabulates crystalline silica content by material: artificial or engineered stone up to 95 per cent depending on the stone pieces or minerals used, sandstone, gritstone and quartzite above 70 per cent, mortar and concrete 25 to 70 per cent, shale 40 to 60 per cent, china stone up to 50 per cent, granite 20 to 45 per cent and typically 30 per cent, slate 20 to 40 per cent, ironstone up to 15 per cent. Employers must assess the risk, record it in writing where they employ more than five people, consider substituting a lower-silica material, control exposure by engineering means first, supply RPE only where engineering controls cannot do the job, face-fit test tight-fitting RPE on clean-shaven wearers, monitor to confirm the WEL is not exceeded, and arrange health surveillance where appropriate.

Health and Safety Executive (HSE)
The specific HSE control sheet for cutting and polishing engineered stone with powered hand-held rotary tools, which is exactly what happens when a quartz worktop is trimmed on site. Issued under the Control of Substances Hazardous to Health Regulations 2002, it describes good control practice for respirable crystalline silica and how to keep exposure below the relevant workplace exposure limits. The named controls are: work with stone containing the lowest crystalline silica content; use on-tool water suppression; control the mist generated by water suppression because the mist itself contains crystalline silica, for example with a water wall local exhaust ventilation booth; use powered air purifying respirators with an assigned protection factor of at least 20 when processing, cleaning or maintaining machinery; and provide health surveillance for workers regularly exposed. On water it requires an adequate supply of clean water and, where water is recirculated, testing and monitoring of the water system and replacing or treating contaminated water per the supplier's instructions, because silica building up in the water degrades both the tooling and the effectiveness of the suppression. Following the guidance is not compulsory unless stated, but doing so will normally be enough to comply.

The landing page for Part H of the Building Regulations in England, and the citation for which edition governed a drainage alteration. It hosts the 2015 edition, 1.23 MB, with the guidance first published to GOV.UK on 4 December 2010 and earlier editions held at the National Archives. The stated scope of the current edition is foul water drainage both above and below ground, pipe sizes, protection of pipes, and manholes and inspection chambers, which are the parts of Part H that bite whenever a bathroom or kitchen is moved rather than replaced in place. The full requirement set runs H1 foul water drainage, H2 wastewater treatment systems and cesspools, H3 rainwater drainage, H4 building over sewers, H5 separate systems of drainage and H6 solid waste storage, so a project that touches a shared or public sewer engages H4 and a build-over agreement as well as the pipe sizing in H1.

An 87 page field study published 1 October 2019 measuring what installed ventilation actually delivers, and its numbers demolish the assumption that a new or upgraded system performs as designed. Of 25 homes visited with continuous mechanical extract, only one met Approved Document F guidance on both extract fan air flow rates and trickle ventilator provision, with whole dwelling extract flow rates in normal low-rate mode ranging from 85 per cent below to 8 per cent above the recommended rate. Only half the homes met the minimum trickle ventilator areas, ranging from 60 per cent below to 107 per cent above the recommended area. On two of three dMEV development sites trickle ventilators had been fitted in the same rooms as the extract fans, contrary to ADF guidance, which can stop fans drawing air through the whole house. On air quality: 11 per cent of the limited monitoring sample had a room where weekly average relative humidity exceeded the recommended monthly average, always the bedroom, and condensation or mould was reported in each such room; 30 per cent exceeded the derived carbon dioxide guideline in the bedroom; and 60 per cent of the detailed monitoring sample exceeded the ADF total volatile organic compound performance standard. Ventilation was found adequate for nitrogen dioxide and carbon monoxide but not for moisture, body odour and VOCs. Notes that Part F 2010 introduced a legal requirement to test and commission installed fans and for the installer to notify the building control body of commissioning and air flow rates.

The Scottish rules that fix how small a kitchen may lawfully be, which have no direct English equivalent. Standard 3.11 requires a kitchen to have space for a gas, electric or oil cooker, or a solid fuel cooker designed for continuous burning, plus kitchen storage of at least 1 cubic metre. Manoeuvring space within the kitchen must be a 1.5 m by 1.5 m square or an ellipse of 1.4 m by 1.8 m, with a clear entry space 1.1 m long by 800 mm wide and access at least 800 mm wide to controls. Activity spaces need at least 1.8 m headroom. An enhanced apartment must be at least 12 square metres with both length and width at least 3.0 m. Drying provision is 1.7 m of outdoor clothes line per bedroom where reasonably practicable, or an indoor space of at least 1 cubic metre with no dimension less than 700 mm. Sanitary fittings themselves are counted under standard 3.12, not here.

Scotland's sanitary provision and accessibility rules, which go further than England's Approved Document G and are the ones a Scottish bathroom project must meet. Clause 3.12.1 requires every dwelling to have at least 1 water closet or waterless closet, 1 wash hand basin per WC, 1 bath or shower and 1 sink, normally in the kitchen, and requires a wash hand basin close to every WC either within the toilet or in the adjacent space forming the sole means of access to it. Clause 3.12.3 requires a dwelling to have at least 1 accessible WC and wash hand basin and at least 1 accessible shower or bath, with unobstructed access at least 800 mm wide to each sanitary facility and unobstructed height of at least 1.8 m above each activity space and above any bath or shower. Where side transfer is allowed a small wall-hung wash hand basin may project up to 300 mm into the activity space in front of the WC, and a projecting basin rim may reduce a route to another facility to not less than 700 mm. A hand-rinse basin may only be installed in a toilet where a full-size wash hand basin exists elsewhere in the dwelling. Clause 3.12.5 applies the accessibility guidance to alterations and extensions: a first new facility of its type on the principal living level or entrance storey must meet clauses 3.12.3 and 3.12.4, alterations must follow 3.12.3 as far as reasonably practicable, existing compliant accommodation must at least maintain its level of compliance after alteration, and may only be removed or relocated where at least equivalent facilities remain.

The regulation that makes a badly fitted gas hob or cooker a criminal matter rather than a workmanship dispute. Regulation 26(1) prohibits any person installing a gas appliance unless it can be used without constituting a danger to any person. 26(2) requires a flued domestic appliance to be connected by a permanently fixed rigid pipe. 26(3) bars the installation of a second-hand appliance without first verifying its safety. 26(4) requires compliance with all other applicable safety legislation. 26(5) prevents an installer leaving an appliance connected unless it is safe or has been sealed off. 26(6) requires a means of shutting off the gas at the appliance inlet unless impracticable. 26(8) forbids removing or defacing any marking showing compliance with safety requirements. 26(9) requires that immediately after any work the person examines the effectiveness of any flue, the supply of combustion air, the operating pressure or heat input, and the operation of the appliance to ensure safe functioning, and reports any defect at once to the responsible person or the owner of the premises.

Regulation 4 requires water fittings to meet the standards set out in Schedule 2; regulation 5 sets the notification procedure requiring the water undertaker's consent before certain installations. Schedule 1 establishes the five fluid risk categories used to size backflow protection. Schedule 2 carries the detailed requirements on materials, watertightness, resistance to internal pressure, backflow prevention, hot water services, WC flushing devices, taps and appliances, including paragraph 7 that no water fitting shall be embedded in any wall. Schedule 3 revokes the former water byelaws.

The regulation that decides whether a tap, cistern, shower or appliance may lawfully be installed. Regulation 4(1) requires every water fitting to be of an appropriate quality and standard and suitable for the circumstances in which it is used, and requires it to satisfy at least one route: an appropriate CE marking under the Directive, conformity with an appropriate harmonised standard or European technical approval, conformity with an appropriate British Standard or another EEA national specification giving an equivalent level of protection, or conformity with a specification approved by the regulator. Regulation 4(2) requires every water fitting to comply with the requirements of Schedule 2 so far as they apply to it. Regulation 4(3) requires the work to be carried out in a workmanlike manner, satisfied by following a relevant British Standard or European technical approval, a specification approved by the regulator, or a method approved by the water undertaker. This is the statutory hook behind WRAS approval and the WaterRegsUK directory of approved products.

The statutory backflow duty that sits behind every check valve, tap gap and pipe interrupter in a house. Paragraph 15 requires that every water system shall contain an adequate device or devices for preventing backflow of fluid from any appliance, fitting or process. A device is adequate only if it conforms to a specification approved by the regulator for the purposes of the Schedule. The device fitted must be appropriate to the highest applicable fluid category to which the fitting is subject downstream before the next such device, which is the rule that forces a category 5 air gap on a bath or bidet with a flexible hose rather than a check valve. Backflow prevention is also required on supply or distributing pipes to prevent backflow between separately occupied premises, and wherever the water undertaker gives notice that it is necessary. The exemption is narrow: it does not apply to a water heater or vented storage vessel where the water temperature does not exceed 25 degrees C and expanded water can flow back into a supply pipe or cistern.

The legal source of the rule that the kitchen cold tap must be mains fed, and the exception people rely on when it is not. Paragraph 27 states that a drinking water tap shall be supplied with water from a supply pipe, a pump delivery pipe drawing water from a supply pipe, or a distributing pipe drawing water exclusively from a storage cistern supplying wholesome water. The third route is the important one: a tank-fed drinking tap is lawful only where the cistern itself supplies wholesome water, which in practice means a cistern meeting the lid, screen, material and maintenance requirements elsewhere in Schedule 2, and that is why a loft cistern of the traditional open type disqualifies the tap it feeds. Read it with paragraph 15 on backflow and with the WaterRegsUK guidance on drinking water taps, which recommends the tap be fed direct from the mains and not through any fitting that stores, treats or filters the water, and which is the reason a water softener installation leaves one tap unsoftened.

The legal bar on non room-sealed gas appliances in bathrooms and bedrooms, which is what decides whether a boiler can be moved into a bathroom or airing cupboard off one. Regulation 30(1) prohibits installing any gas appliance in a room used or intended to be used as a bathroom or shower room unless it is a room-sealed appliance. Regulation 30(2) prohibits a gas fire, other gas space heater or gas water heater of more than 14 kilowatt gross heat input in a room used or intended as sleeping accommodation unless it is room-sealed. Regulation 30(3) allows such an appliance of 14 kilowatt gross heat input or less, and an instantaneous water heater, in sleeping accommodation only where it is room-sealed or incorporates a safety control designed to shut the appliance down before a dangerous quantity of combustion products builds up in the room. Regulation 30(4) extends all three prohibitions to a cupboard or compartment within such a room, and to a cupboard, compartment or space adjacent to such a room if there is an air vent from it into the room.

The Welsh edition of Part H, November 2023, and the source of the waste pipe sizes every bathroom and kitchen move depends on. Every point of discharge must have a trap that retains a minimum seal of 25 mm of water under working and test conditions. Table 1 sets minimum trap sizes and seal depths: washbasin and bidet 32 mm trap with 75 mm seal; bath, shower, food waste disposal unit, urinal bowl, sink, washing machine and dishwashing machine 40 mm trap with 50 mm seal, except the sink and appliance group listed at 75 mm seal; WC pan with outlet under 80 mm, 75 mm trap with 50 mm seal; WC pan with outlet over 80 mm, 100 mm trap with 50 mm seal. A basin seal may drop to 50 mm only with flush grated wastes without plugs on spray tap basins, and where an appliance discharges directly to a gully the seal may drop to not less than 38 mm. Other figures: a branch discharge pipe must not enter a stack lower than 450 mm above the invert at the foot of the stack; a branch serving one appliance should be the same diameter as its trap; branch pipes of 75 mm or more joining a stack of equal diameter need a 50 mm radius sweep, smaller ones 25 mm radius or 45 degrees; a boiler condensate connection needs a 75 mm condensate trap; a ventilating pipe should connect within 750 mm of the trap and be at least 32 mm where it has up to 5 bends.

Regulation 36 requires the estimated consumption of wholesome water to be not more than 110 litres per person per day where a dwelling is erected, or 125 litres per person per day where a dwelling is formed by a material change of use, against England's 125 litres with 110 as an optional tighter standard. Regulation 37 requires the water efficiency calculation to be notified to the building control body, and the completed notice must state, for example, less than 110 litres per person per day using the fittings approach.

WALES, and this is a hard contradiction with England. The Welsh Approved Document P states that notifiable jobs include new circuits back to the consumer unit AND extensions to circuits in KITCHENS and special locations such as bathrooms, and that consumer unit replacements are notifiable. England's Approved Document P 2013 edition defines a special location at regulation 12(9) as only the zone around a bath tap or shower head, extending 2.25 metres vertically and 0.6 metres horizontally from a bath tub or shower tray, or 1.2 metres from a shower head where there is none, plus a room containing a swimming pool or sauna heater, so a kitchen is NOT a special location in England and extending a kitchen circuit there is not notifiable. In Wales it is. The Welsh document also confirms replacement, repair and maintenance work is generally not notifiable even in a kitchen or special location, that in large bathrooms the special location is bounded by the walls of the bathroom, and that conservatories, attached garages, detached garages and sheds are not special locations, so work there is notifiable only if it involves a new circuit.

BS 8000-11:2011, published 31 January 2011, committee B/539, current. It gives recommendations on basic workmanship on building sites, both commercial and domestic, for the tasks frequently carried out in wall and floor tiling. It applies to fixing ceramic and agglomerated stone tiles, natural stone and terrazzo tiles and slabs, and mosaics to walls and floors using adhesive and mortar. It states plainly that its recommendations are not necessarily comprehensive and that a project specification might need to cover more. It signposts the rest of the family: design aspects of wall and floor tiling are in BS 5385, natural stone cladding and lining in BS 8298, and the harmonised product specifications are BS EN 12057 for natural stone tiles, BS EN 12058 for slabs, BS EN 14411 for ceramic tiles, BS EN 15285 for agglomerated stone and BS EN 12004 for adhesives, with BS EN 12440 for natural stone naming.
