The Building Regulations 2010

Provisions the documents cite: reg 7(1) and reg 7(2); Part 2A regs 11A–11Q (dutyholders and competence) — in particular 11D (appointment of principal designer and principal contractor), 11E (considerations before a person carries out work), 11F–11I (competence and ceasing to be competent), 11J–11N (duties of dutyholders) and 11O (notification of change of dutyholder); reg 16(4), (4A) and (4B) (completion notice and dutyholder statements); reg 12(6)(a) and Schedule 3 (self-certification schemes: no building notice or full plans where the work is only of a Schedule 3 type carried out by a person described for it); reg 17 (completion certificates); reg 20 (self-certification certificate and notice within 30 days); reg 2 (meaning of domestic client); reg 11C (domestic clients, England: who carries out the client duties; deemed appointments); reg 11A(4)–(5) (building information; cooperation — not transferred for a domestic client)

What it requires

reg 7(1) — building work carried out with adequate and proper materials, appropriate for the circumstances, adequately mixed or prepared, and applied, used or fixed so as adequately to perform the functions for which they are designed; and in a workmanlike manner. This is the duty that installing outside a tested fire-stopping detail breaches, and it is why that citation belongs here rather than in a sentence about retaining evidence. reg 7(2) — combustible materials in external walls of relevant buildings; this, not the Building Safety Act, is where the cladding materials restriction sits. Note the original reg 7 was renumbered 7(1) in England on 21 December 2018. Part 2A (dutyholders and competence, England) — the client makes suitable arrangements for planning, managing and monitoring a project, including sufficient time and resources, so that design and building work comply with all relevant requirements, keeps them under review and gives building information to every designer and contractor (reg 11A). Where there is, or is reasonably foreseeable to be, more than one contractor, the client appoints in writing a principal designer and a principal contractor — before the construction phase begins or, for higher-risk building work, before the building control approval application — or certifies in writing that the CDM principal designer and principal contractor are treated as appointed; an appointment that ends is replaced as soon as reasonably practicable, the client carries the role's duties until it is, and a sole contractor is treated as the principal contractor (reg 11D). Domestic clients (England) — a domestic client is a client for whom a project is being carried out which is not in the course or furtherance of a business of that client (reg 2). Where the client is a domestic client, the duties in regs 11A(1)–(3) and 11E(2)–(5) must be carried out by the contractor where there is only one contractor for the project, or, where there is more than one, by the principal contractor or by the principal designer where the client and the principal designer agree in writing that the principal designer is to fulfil them; if a domestic client fails to make the reg 11D appointments, the designer in control of the design phase is the principal designer and the contractor in control of the construction phase is the principal contractor; reg 11D(5) does not apply to a domestic client (reg 11C). The duties that pass under reg 11C are only those in regs 11A(1)–(3) (making suitable arrangements for planning, managing and monitoring the project, including sufficient time and resources, and maintaining and reviewing them) and 11E(2)–(5); reg 11C does not transfer the reg 11A(4) duty to provide building information as soon as is practicable to every designer and contractor, or the reg 11A(5) duty to cooperate with any other person working on or in relation to the project to the extent necessary to enable anyone with a duty or function under the Regulations to fulfil it, so those stay with the domestic client (REASONING from the wording of reg 11C). In Wales the equivalent is reg 11T, under which a domestic client may take the duties on or assign them by signed written statement (register entry building-regs-wales-part-2b). Before permitting anyone to carry out building or design work, the person engaging them takes all reasonable steps to be satisfied that they meet the competence requirements (or are in supervised training) and can plan, manage and monitor their work; for a principal designer or principal contractor the client also checks the role competence in reg 11G(1) or 11H(1); on a higher-risk building the person engaging asks about serious sanctions in the previous five years (reg 11E). Anyone carrying out building or design work must have the skills, knowledge, experience and behaviours (an individual) or the organisational capability (an organisation) to do the work in compliance and to fulfil their dutyholder duties; an organisation appointed principal designer or principal contractor designates a competent individual to manage the function (regs 11F–11H). A person who ceases to be competent notifies the client, or the person who engaged them and the principal designer or principal contractor (reg 11I). Dutyholders plan, manage and monitor their own work, cooperate and report compliance concerns; the principal designer and principal contractor coordinate design and building work, liaise with each other and, within 28 days of their appointment ending, give the client a document explaining the arrangements they put in place (regs 11J–11N). Where, after a building control approval application or building notice, the client changes, or a principal contractor, sole contractor, principal designer or sole or lead designer is appointed, a notice with the location, the contact details of the new and outgoing parties and the dates goes to the relevant authority within 14 calendar days — from the new client, the client or, for a domestic client, the person appointed; reg 11O does not apply to higher-risk building work. Minor work in Schedule 4 is outside Part 2A (reg 11P). reg 16(4)–(4B) (England) — not more than five days after the work is completed, the person carrying out the work gives the relevant authority a notice including the contact details of the client, the principal contractor (or sole contractor) and the principal designer (or sole or lead designer); a statement that the work is complete; a statement signed by the client that to the best of their knowledge the work complies with all applicable requirements of the building regulations; and a statement signed by each principal contractor (or sole contractor) and principal designer (or sole or lead designer) giving their contact details, dates of appointment and confirmation that they fulfilled their Part 2A duties. Where a dutyholder's statement cannot be included, the notice gives the reasons instead (reg 16(4B)). The Wales version of reg 16 refers to Part 2B. WATCH — from 1 October 2026 the Building Safety Levy (England) Regulations 2025 (SI 2025/1236) amend reg 16: reg 57 adds reg 16(4A)(f), so that where building safety levy information was required with the full plans application the completion notice must also include a levy liability statement signed by the named client that a notice of no charge was received and not cancelled or that the levy has been paid in full (new reg 16(5B)); reg 58 amends reg 17 so the completion certificate is withheld until the collecting authority agrees that statement; and reg 28 adds levy information to the commencement notice (reg 16(3CA)–(3CC)) and inserts reg 16A. reg 12(6)(a) — a person carrying out building work need not give a building notice or apply for building control approval with full plans where the work consists only of work described in column 1 of the Schedule 3 table carried out by a person described in column 2. Schedule 3 covers, among others, heat-producing gas appliances (a member of a class of persons approved under reg 3 of the Gas Safety (Installation and Use) Regulations 1998), oil-fired and solid fuel appliances, heating and hot water systems, ventilation and air conditioning, fixed low or extra-low voltage electrical installations in dwellings, replacement windows, rooflights, roof windows and doors, sanitaryware in dwellings, cold water supplies, microgeneration and renewables, replacement roof coverings and cavity, internal and external wall insulation, each by a person registered with a named scheme operator. In England reg 12(6A) says a person carrying out work to which Part P applies is required to give a building notice or full plans where the work is a new circuit, a consumer unit replacement or an addition or alteration to circuits in a special location; how that sits with reg 12(6)(a) for a registered installer was not settled from the text and is for the building control body. reg 20 — where the work is of a Schedule 3 type done by a person described for it, the building control authority may accept that person's certificate as evidence that regs 4 and 7 are satisfied; not more than 30 days after completion the person gives the occupier a copy of the certificate and gives the authority notice or the certificate (reg 20(2)–(3)); on a higher-risk building the client tells the person carrying out the work (reg 20(1A)); the certificate is evidence, but not conclusive evidence, of compliance with the requirements it specifies, and must say so (reg 20(5)–(6)). reg 17 — the relevant authority (England) or building control authority (Wales) gives a completion certificate within eight weeks of receiving the reg 16(4) completion notice (in England, or the notice under reg 22A(1) of the Building (Registered Building Control Approvers etc.) (England) Regulations 2024) where, after taking all reasonable steps, it is satisfied that the relevant provisions — Schedule 1 and the listed energy, water efficiency, fire safety information and energy performance certificate requirements — have been complied with; the certificate is evidence, but not conclusive evidence, of compliance and must include a statement to that effect (reg 17(1)–(5)).
