    The 714-page handbook that carries Scotland's own numbers, which differ from England's. Table 4.3 sets private stair geometry at minimum rise 100 mm, maximum rise 220 mm, minimum going 225 mm, tread not less than the going and maximum pitch 42 degrees; Table 4.4 sets any other stair at maximum rise 170 mm, minimum going 250 mm and maximum pitch 34 degrees; going plus twice the rise must be between 550 mm and 700 mm, tapered treads at least 50 mm at the narrow end, a flight generally 3 to 16 rises. Table 4.5 puts effective width at 900 mm for a private stair, 800 mm where a continuous handrail is on both sides, 600 mm where it serves only sanitary accommodation or one room, and 1.0 m for any other stair, with stringer or newel projection no more than 30 mm. Clause 4.3.15 sets handrail height at 840 mm to 1.0 m above the pitch line, 4.3.16 headroom at 2.0 m, and 4.3.17 points spiral and helical stairs to BS 5395-2:1984. Table 5.1 sets separating element performance at 56 dB DnT,w airborne and 56 dB L'nT,w impact for new build, relaxed to 53 dB and 58 dB for conversions of traditional buildings.

    Scotland's equivalent of the Approved Documents, and the reason a note that quotes only English rules is wrong for a fifth of the UK. This edition is in force from 6 April 2026 and applies to building warrants submitted on or after that date and to work not requiring a warrant commenced from that date. It gives guidance on achieving the standards set in the Building (Scotland) Regulations 2004, arranged in sections rather than parts: section 3 environment (ventilation, drainage, condensation), section 4 safety (electrical safety and installations, glazing and danger from accidents, including clause 4.13 which invokes PAS 24 for security), section 6 energy (U-values for windows and doors) and section 7 sustainability. Scotland uses a building warrant and a completion certificate rather than a building notice, and has no Part P competent person scheme equivalent, so electrical work is covered by the warrant system instead.

    The definitive list of what counts as a statutory nuisance in England and Wales, which is the legal hook for most neighbour and building-work complaints. Section 79(1) names, among others: (a) any premises in such a state as to be prejudicial to health or a nuisance, which is the route used against damp and disrepair; (b) smoke emitted from premises; (c) fumes or gases emitted from premises; (d) dust, steam, smell or other effluvia arising on industrial, trade or business premises; (e) any accumulation or deposit; (fb) artificial light emitted from premises, which covers security lighting; (g) noise emitted from premises; and (ga) noise from a vehicle, machinery or equipment in a street. Each limb requires the matter to be prejudicial to health or a nuisance. Section 79(1) also places a duty on every local authority to inspect its area for statutory nuisances and, where a person living in its area complains, to take such steps as are reasonably practicable to investigate. Section 79(1A) excludes matters caused by land being in a contaminated state, and section 79(2) excludes Crown defence premises from the smoke, artificial light and noise limbs.

    The National Archives (legislation.gov.uk)

    The private route that lets an individual go to the magistrates' court directly, without waiting for the council, when aggrieved by a statutory nuisance; in Scotland the equivalent is a summary application to the sheriff. If satisfied the nuisance exists, or that though abated it is likely to recur, the court must make an order requiring the defendant to abate it within a specified time and to execute any works necessary, or prohibiting recurrence, and may also impose a fine not exceeding level 5 on the standard scale. Section 82(3) allows the court, where the nuisance makes premises unfit for human habitation, to prohibit their use for habitation until they are made fit. Section 82(4) fixes who is sued: normally the person responsible, but (b) where the nuisance arises from any defect of a structural character it is the owner of the premises, and (c) where the person responsible cannot be found, the owner or occupier. Section 82(5) makes each of several responsible persons liable even where their own contribution would not by itself be a nuisance.

    SI 1988/1324, the flammability regime that applies to the soft furnishings and any loose upholstered elements a fitted-furniture project buys in. It revoked the Upholstered Furniture (Safety) Regulations 1980 and its 1983 amendment and imposes requirements on new domestic furniture, including garden furniture that may be used indoors and furniture for use in caravans, subject to exceptions for certain furniture. Some requirements also apply to second-hand furniture, and the regulations do not apply to goods for export. The point for a note is that these regulations bite on furniture supplied in the course of a business, not on the building fabric.

    UK Health Security Agency and Centre for Climate and Health Security

    UKHSA guidance published 7 August 2025, applying to England, on the allergens and irritants in indoor air, useful for any note that claims a renovation improves or harms air quality. States that indoor bioaerosols can contribute up to 34 per cent of indoor air pollution, and that people in Western countries spend the majority of their time indoors. Identifies the protein-based allergens as mould spores, which thrive in damp poorly ventilated spaces such as bathrooms and arise from leaks, condensation, poor heating or inadequate ventilation; house dust mites, which thrive in warm humid environments in bedding, carpets and upholstered furniture; and pet dander from skin flakes, urine and saliva. Separately names non-protein respiratory irritants: volatile organic compounds emitted by paints, cleaning agents and air fresheners, and particulate matter from cooking, smoking and open solid-fuel fireplaces. Warns that energy efficiency and adaptation measures can have unintended consequences for indoor environmental quality, and that poorly installed mechanical ventilation can worsen air quality.

    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.

First published 27 August 2015 and last updated 19 June 2025, it is issued as two PDFs, Approved Document B dwellinghouses at 5 MB and buildings other than dwellinghouses at 6 MB, and must be read with four amendment slips, the most recent applicable from 20 December 2025. A note that says an FD30 door is needed at the head or foot of a loft stair, or that an open plan ground floor triggers a sprinkler or an escape window, should cite the Welsh document for a Welsh reader.

    The Welsh ventilation guidance, which sets the extract rates a new utility room, boot room, en suite or downstairs WC has to meet in Wales. First published 3 April 2017 and last updated 7 April 2026, the page carries Approved Document F volume 1 for dwellings as a 910 KB PDF and volume 2 at 488 KB, plus the September 2013 amendment slip. Critically for date-sensitive notes, it also carries a new Approved Document F volume 1 for dwellings that takes effect on 4 March 2027, which is a different commencement date from the English 2026 edition, so a UK-wide note must not treat the two nations as switching over together.

    The Welsh guidance covering sanitary provision, hot water safety and water efficiency, the part that governs adding a WC, basin, shower or en suite. First published 5 April 2017 and last updated 10 May 2023, issued as a single 1 MB PDF and to be read with the September 2013 amendment slip. A note that quotes the English water efficiency calculation or hot water safety requirements for a new bathroom should check the Welsh document separately, because Wales sets its own water efficiency standard for new dwellings.

It carries volume 1 for dwellings and volume 2 for other buildings as current PDFs, and a new Approved Document L volume 1 for dwellings that takes effect on 4 March 2027. Any note quoting fabric U-value targets for a floor, wall, roof or a conservatory's thermal separation should state which nation the figure belongs to, since Wales publishes its own Part L with its own commencement dates rather than adopting the English edition.

  14. very strong RN-HCKL9C

    Welsh Government

    The Welsh Part M, and the document that decides whether a downstairs WC may be removed in a renovation. Section 10 sets the objective as a WC in the entrance storey located so that no stair need be negotiated to reach it from the habitable rooms in that storey; where the entrance storey has no habitable rooms, a WC in either the entrance storey or the principal storey is reasonable. Paragraph 10.3 says requirement M4 is satisfied if a WC is provided on that basis, the door to the WC compartment opens outwards and is positioned to let a wheelchair user reach the WC with a clear opening width per Table 4, and the compartment gives clear space for wheelchair access with the washbasin positioned so it does not impede access, per Diagrams 31 and 32. It also states plainly that it will not always be practical for the wheelchair to be fully accommodated inside the compartment. Crucially, the guidance on material alterations gives the worked example: removing a WC in the entrance storey of a dwelling is a material alteration if it is the only WC in that storey and the storey contains habitable rooms, and it must not be removed or made less compliant unless another WC no less compliant is provided in that storey.

It is the code of practice for designing sanitary facilities and setting the scale of provision of sanitary and associated appliances, and it supersedes BS 6465-1:2006. It sits in a suite of four standards: Part 1 scales of provision, Part 2 space recommendations, Part 3 selection, installation and maintenance, Part 4 provision of public toilets. It traces back to CP 305-1 first published July 1952, with the third edition issued as BS 6465-1 in February 1984 and the fifth in March 2006. Use it to establish how many WCs and basins a dwelling should have.

It gives recommendations for the space required around all sanitary appliances so they are convenient in use and can be maintained and cleaned, which is the source for activity space and clearance dimensions in front of a WC, basin, bath and shower. It is one of a suite of four: Part 1 scales of provision, Part 3 selection and installation, Part 4 public toilets. As a code of practice its recommendations are guidance rather than specification, so a claim should be worded as recommended clearance, not a legal minimum.

    The standard behind internal noise level targets quoted for bedrooms and living rooms, published 28 February 2014 and current. BS 8233 gives guidance on the control of noise in and around buildings and applies to the design of new buildings and to refurbished buildings undergoing a change of use. It expressly does not cover assessing the effect of changes in external noise on occupants of an existing building, specialist applications such as auditoria and cinemas, which fall to BS ISO 9568, vibration control except where it appears as radiated sound, or noise breaking out of a building to external receptors. A note about soundproofing an existing room should therefore treat it as a design reference, not as a compliance test.

    BS EN 520:2004+A1:2009, published 22 November 2004 with Amendment 1 in 2009, committee B/544, under review. Clause 1 specifies the characteristics and performance of gypsum plasterboards for building construction, including boards intended for secondary manufacturing operations and boards designed to receive either direct surface decoration or gypsum plaster. The product performance characteristics it covers are reaction to fire, water vapour permeability, flexural strength (breaking load), impact resistance and thermal resistance. It separates out the characteristics that belong to the assembled system rather than the board alone, and are measured on assemblies simulating end use conditions: shear strength, fire resistance, impact resistance, direct airborne sound insulation and acoustic absorption. It also covers additional technical characteristics important for the use and acceptance of the product by the construction industry, the reference tests for them, and evaluation of conformity. This is the standard that defines the plasterboard type letters a merchant lists, so cite it for fire-resistant, moisture-resistant and higher-density board claims.

    BSI (British Standards Institution)

    STATUS: WITHDRAWN on 29 October 2025, a very recent change. BS 5266-1:2016 was published 31 May 2016 and gave the code of practice for the design, installation and wiring of electrical emergency lighting, covering three purposes: assisting occupants to leave a building in an emergency, protecting those who remain inside, and allowing operations to continue if normal lighting fails, including recommendations for areas with fixed seating. Its scope covers common access routes in blocks of flats but EXCLUDES single family dwellings, a distinction a note should keep when it tells a homeowner that emergency lighting is required. Because it was withdrawn in October 2025, any note citing BS 5266-1:2016 needs checking against the current edition. Catalogue page confirms number, title, publication date, withdrawal date and scope but does not name the replacement.

    STATUS: CURRENT. BS 6222-2:2009+A1:2017 (base edition published 31 January 2009, amended 2017) specifies the performance requirements and test methods for the strength and durability of the structure of domestic and residential fitted kitchen units, peninsular units, island units and breakfast bars. It EXCLUDES free standing units and storage furniture for other applications, and it does not cover worktop or storage unit safety, which sit in BS EN 14749:2016+A1:2022, Furniture. Domestic and kitchen storage units and kitchen worktops. Safety requirements and test methods. Together with BS EN 1116:2018 for coordinating sizes this is the pair a kitchen note should cite: BS EN 1116 for whether a unit fits, BS 6222-2 for whether its carcass will survive use.

    The accessibility code of practice that Approved Document M sits alongside. Paywalled, so only the catalogue page is public; it confirms BS 8300-2:2018, published 31 January 2018, status Current, and that it is part 2 of a two-part standard, with BS 8300-1:2018 (also published 31 January 2018, also Current) covering the external environment including parking, setting-down points, access routes and approaches to entrances. Part 2 covers external features affecting external access routes, and building interiors including entrances, reception facilities, horizontal and vertical movement and building facilities. Crucially for a home renovation note, the catalogue page states plainly that BS 8300-2 does NOT apply to individual dwellings; its residential scope is nursing, residential and care homes, student accommodation and the COMMON PARTS of blocks of flats. It also confirms the recommendations apply largely to new buildings but can be used to assess and improve existing ones, and that the extent to which they apply to listed and historic buildings is decided case by case.

    BSI (British Standards Institution)

    STATUS: WITHDRAWN on 31 October 2015, superseded by BS 9991:2015 (and since by a further revision). BS 9991:2011 was published 31 December 2011 and itself superseded BS 5588-1:1990. It gave the code of practice for fire safety in residential buildings, covering dwellings, residential accommodation blocks for up to six people and sheltered and extra care housing, applying to new design and to material alterations, extensions and changes of use, across ten sections covering means of escape, stairs, firefighting access, active fire protection, construction, mechanical systems, ancillary accommodation and management. It excludes hotels, caravans, hospitals, care homes, detention facilities, hostels and houses in multiple occupation. This is the standard a loft conversion note reaches for when discussing protected stairs and escape windows, so citing the 2011 edition is citing a withdrawn one. Catalogue page confirms number, title, publication date, withdrawal date, supersession and scope.

    BSI (British Standards Institution)

    STATUS: CURRENT. BS 9999:2017 was published 31 January 2017 and supersedes BS 9999:2008, which is withdrawn. It gives the code of practice for fire safety in the design, management and use of buildings, aimed at life safety for occupants and firefighters with property and business protection as secondary objectives. The 2017 revision added a design process flowchart, brought in watermist suppression systems, revised smoke and heat control guidance, added recommendations for fire curtain barriers and updated the shopping complex provisions. Crucially for a home renovation note, it EXCLUDES individual dwellinghouses, and has limited application to specialist buildings such as hospitals and places of lawful detention, so it is the wrong standard to cite for a house: use Approved Document B Volume 1 for dwellings and BS 9991 for residential buildings.

It specifies coordinating sizes for kitchen units, worktops, recess panelling, furniture fronts and decorative panels, and for kitchen appliances (white goods and ovens) and further installation elements such as sinks, giving the height, width and depth dimensions and the space needed to integrate an appliance into a unit. This is the standard behind the 600 mm module and standard carcass depths that make an integrated appliance fit a run of units, and it is what a note should cite when explaining why a replacement dishwasher or oven fits an existing housing. It does not cover commercial kitchens in hotels or restaurants. Catalogue page confirms number, title, date, status, ISBN and scope; the dimension tables are paywalled.

    STATUS: CURRENT.

The classification is the useful part for a note: it separates SAFETY limiting restrictors from CHILD SAFETY limiting restrictors, with distinct requirements aimed at reducing the risk of accidental falls, which is what a note should cite when it says a window above ground floor level needs a child resistant restrictor rather than any restrictor. It applies only where the restriction falls within the specification in Annex A, E or G of EN 1191:2012 for the manufacturer's intended use.

It defines the single number quantities for airborne sound insulation in buildings and building elements, that is the method for converting a frequency dependent measurement into one figure, and it covers spectrum adaptation terms for different noise sources including internal noise and external traffic noise. The 2020 revision moved content in from ISO 10140-1:2016 and ISO 10140-5:2010 and updated the references.

    TM59 is the dynamic thermal modelling methodology that Approved Document O Section 2 names as its alternative to the simplified glazing and free-area route, so it is a required citation for any note about overheating. This page is for the 2026 edition, published July 2026, 39 pages, ISBN 9781912034123, and it is FREE to download at both standard and member rate, unusually for CIBSE. The critical compliance point stated on the page: TM59 (2017) is still the version required for compliance with Part O, and CIBSE recommends TM59 (2026) only for industry best practice while it discusses with the Building Safety Regulator how the updated weather files and new version might be incorporated into the Approved Documents. So a note must not tell a reader that the 2026 edition satisfies Part O. The 2026 update adds a new bedroom overheating criterion based on Loughborough University research, updated ceiling fan modelling presenting fans as an effective passive comfort solution, and mandates that all homes be tested under unconstrained conditions using 2050s weather data. TM59 applies to houses, apartments, sheltered accommodation, care homes, student accommodation, prisons and bedrooms in hotels and hospitals, and covers new dwellings and major refurbishments. The page also records that in 2026 the Climate Change Committee raised risks to buildings and communities from heat to its highest category, Critical Action needed.
