47 Regularisation of unauthorised building work
1 This regulation applies where it appears to the regulator that unauthorised building work has been carried out on or after 11th November 1985.
2 Where this regulation applies, the owner (in this regulation referred to as “the applicant”) may make an application in writing to the regulator in relation to the unauthorised building work (“regularisation certificate application”).
3 No regularisation certificate application may be made where unauthorised building work is a major change.
4 The regularisation certificate application must be accompanied by—
(a) a statement that the application is made in accordance with this regulation,
(b) a description of the unauthorised building work,
(c) a plan of the unauthorised building work,
(d) where the application is made by someone on behalf of the owner, a statement signed by the owner confirming they agree to the application being made and that the information contained in the application is correct.
5 Where the regulator receives a regularisation certificate application, it may require the applicant to take such steps as the regulator thinks appropriate for the regulator to ascertain whether additional building work may be required in order for the unauthorised building work to secure compliance with all applicable requirements of the building regulations.
6 Where the regulator is satisfied that additional building work is required to secure that the unauthorised building work satisfies the applicable requirements (taking account of any dispensation or relaxation given in accordance with sections 8 and 9 of, and Schedule 2 to, the 1984 Act) then the regulator must reject the application and accordingly an application for building control approval must be made in relation to the additional building work.
7 Where the regulator is satisfied, after taking all reasonable steps for that purpose that—
(a) the applicable requirements of the building regulations have been satisfied (taking account of any work carried out and any dispensation or relaxation given in accordance with sections 8 and 9 of, and Schedule 2 to, the 1984 Act), and
(b) no additional building work is required to secure that the unauthorised building work satisfies the applicable requirements (taking account of any such dispensation or relaxation),
the regulator may give a certificate to that effect (in this regulation referred to as “a regularisation certificate”).
8 A regularisation certificate is evidence (but not conclusive evidence) that the applicable requirements of the building regulations specified in the certificate have been complied with in relation to the work specified in the certificate.
9 Where a regularisation certificate is granted in relation to building work, Parts 2 to 5 of these Regulations cease to apply to that work.
10 Subject to paragraph (12), where a regularisation certificate is granted the applicant must, no later than five days after the certificate has been received, give the building work information and a copy of the certificate to—
(a) the accountable person who is responsible for the part of the building in relation to which the work described in the certificate relates, and
(b) the responsible person, if any, for the part of the building in relation to which the work described in the certificate relates.
11 For the purposes of paragraph (10) the “building work information” is—
(a) where Part B of Schedule 1 to the 2010 Regulations imposes a requirement in relation to the unauthorised building work, information relating to—
(i) the design and construction of the building and the services, fittings and equipment provided in or in connection with the building;
(ii) the design of the change of use and building work to implement it;
(iii) the composition of materials used,
which will assist the responsible person to operate and maintain the building with reasonable safety;
(b) where paragraph F1(1) of Schedule 1 to the 2010 Regulations imposes a requirement in relation to the unauthorised building work, sufficient information about the building’s ventilation system and its maintenance requirements so that the ventilation system can be operated in such a manner as to provide adequate means of ventilation;
(c) where paragraph L1 of Schedule 1 to the 2010 Regulations imposes a requirement in relation to the unauthorised building work, sufficient information about the building, the fixed building services and their maintenance requirements so that the building can be operated in such a manner as to use no more fuel and power than is reasonable in the circumstances;
(d) where paragraph L2 of Schedule 1 to the 2010 Regulations applies in relation to the unauthorised building work, sufficient information about the system for on-site electricity generation in respect of its operation and maintenance requirements so that the system may be operated and maintained in such a manner as to produce the maximum electricity that is reasonable in the circumstances and delivers this electricity to the optimal place for use;
(e) where Part O of Schedule 1 to the 2010 Regulations applies in relation to the unauthorised building work, sufficient information about the provision made in accordance with Part O so that the systems in place further to Part O can be operated in such a manner as to protect against overheating.
12 Paragraph (10) does not apply where the applicant is a domestic client.
13 In this regulation—
“responsible person” has the meaning given in article 3 of the Regulatory Reform (Fire Safety) Order 2005;
“unauthorised building work” means any building work in relation to a higher-risk building which is carried out without—
(a) a building control approval under regulation 7 (building control approval applications for HRB work or stage of HRB work: decisions) or 15 (building control approval applications for work to existing HRB: decisions) being granted by the regulator;
(b) where the building work is a major change, a building control approval under regulation 24 (change control applications: decisions);
(c) where the building work is a notifiable change, a notification under regulation 18(3) (change control),
but work is not unauthorised building work to the extent that it consists only of scheme work or exempt work.

(b) full plans, in relation to HRB work or work to existing HRB to a particular building, were deposited with a local authority.
(2) Where this paragraph applies, notwithstanding the commencement of section 32 of the Building Safety Act 2022, on 1st October 2023 the local authority for the area continues to be the building control authority in relation to the higher-risk building and accordingly the duties and functions of local authorities under section 91 of the 1984 Act continue to apply in relation to that work as if it were not higher-risk building work.
See section 121A of the Building Act 1984 for the definition of “building control authority”, which was inserted by section 32 of the Building Safety Act 2022 (c. 30).
1984 c. 55. Section 91 is amended by section 32 of the Building Safety Act 2022 (c. 30).

(4) In addition to the continuing application of the provisions referred to in sub-paragraph (3), not more than five working days after the day on which the work is to be regarded as sufficiently progressed the person carrying out the work must give a notice to that effect to the local authority and where sub-paragraph (1)(a) applies in relation to the work, give a copy of the notice to the approved inspector.
(5) Sub-paragraphs (1) to (4) cease to apply in relation to the work where before 6th April 2024—
(a) the approval for the work lapses by virtue of section 32 of the 1984 Act (as that provision had effect immediately before 1st October 2023), or
(b) the initial notice for the work, or the part of that notice which relates to the higher-risk building, is cancelled under section 52(5) of the 1984 Act (as that provision had effect immediately before 1st October 2023),
and paragraph 3 applies instead to the work.

2 From October 2023: cases where full plans are rejected
(1) This paragraph applies where, in relation to work to a particular building, full plans were deposited with a local authority before 1st October 2023 and in accordance with any provision of Part 1 of the 1984 Act or a local enactment the local authority has rejected those plans on or after that date (“the rejection date”).
(2) Where this paragraph applies then with effect from the rejection date the regulator, and not the local authority for the area, is the building control authority in relation to the higher-risk building and accordingly—
(a) the duties and functions of the regulator under section 91 of the 1984 Act apply in relation to the higher-risk building or any proposed higher-risk building;
(b) Parts 2 to 6 of these Regulations apply to any HRB work or work to existing HRB from the rejection date with the modifications provided in this paragraph except that regulation 47 (regularisation) does not apply in relation to any work carried out before the rejection date and accordingly any reference to a regularisation certificate in Parts 2 to 6 of these Regulations is to be ignored, and
(c) the 2010 Regulations, to the extent they apply to higher-risk buildings, apply to any of the work from the rejection date.
(3) Within 10 working days of the rejection date the person intending to carry out the work must give a notice to the regulator setting out—

(h) details of the work which has been carried out together with a summary of the inspections undertaken by the local authority in relation to the work.
(4) Where any work was carried out before the rejection date the person who carried out the work or the owner must comply with any notice from the regulator requiring them within a reasonable time to cut into, lay open or pull down so much of the work as prevents the regulator from ascertaining whether the work contravenes any requirement of the building regulations.
(5) Where any work was carried out before the rejection date (“the HRB project”) and on or after that date a building control approval application for HRB work or a building control approval application for work to existing HRB is submitted to the regulator in respect of the HRB project, then in addition to the requirements of regulation 4 the person who carried out the work must provide the regulator with such plans as are necessary to show the work already carried out complies with all applicable requirements of the building regulations.

(2) Where this paragraph applies then with effect from the date paragraph 1(1) to (4) ceases to apply in relation to the work (“the cessation date”) the regulator, and not the local authority for the area, is the building control authority in relation to the higher-risk building and accordingly—
(a) the duties and functions of the regulator under section 91 of the 1984 Act apply in relation to the higher-risk building or any proposed higher-risk building;
(b) these Regulations apply to any of the work from the cessation date, and
(c) the 2010 Regulations, to the extent they apply to higher-risk buildings, apply to any of the work from the cessation date.
Sch. 3 para. 3 in force at 1.10.2023, see reg. 1(1)

EXPLANATORY NOTE
(This note is not part of the Regulations)
This instrument is part of a number of Regulations which implement Part 3 of the Building Safety Act 2022 (c. 30).
Section 91ZA of the Building Act 1984 (as inserted by section 32 of the Building Safety Act 2022, which is to come into force on 1st October 2023, provides for the regulator to be the building control authority in relation to any higher-risk building in England and any proposed higher-risk building.
The requirements in the Building Regulations 2010 continue to apply to higher-risk buildings. Amendments (to be made elsewhere) to those Regulations disapply most of the procedural requirements in those Regulations, consequently procedures in this instrument apply instead.
Part 2 of these Regulations sets out the procedures for applying for building control approval in relation to higher-risk buildings. Applications must be submitted to the regulator giving the information required and accompanied by the plans and documents required. Building control approval may, with the applicant’s consent, be subject to a requirement, for example, to not progress beyond a specified point without agreement of the regulator or that more detailed plans or documents could be approved by the regulator at a later date.
Part 3 of these Regulations sets out the change control process where any document relating to the work which was approved by the regulator at the application stage (or subsequently under a requirement or a change control) is to be changed. And provision is also made in this Part for change to the client, principal contractor or principal designer, insolvency etc of a client and variation of a requirement imposed on a building control approval.
Part 4 of these Regulations sets out provisions in relation the golden thread information, mandatory occurrence reporting and the handover of information on completion of the work.
Part 5 of these Regulations sets out the procedures for applying for a completion certificate in relation to higher-risk buildings. Applications must be submitted to the regulator giving the information required and accompanied by the plans and documents required. Provision is also made for partial completion certificates where it is proposed a building (or part of a building) is occupied before all of the higher-risk building work is completed.
Part 6 of these Regulations sets out provision relating to inspections, testing and sampling, regularisation of unauthorised work, review by the regulator of its decisions, and appeals in relation to reviewed decisions and the procedure under section 30A of the Building Act 1984 (which provides that a request can be made to the Secretary of State for determination of an application where the regulator has not made a decision within the time limit prescribed).
Part 7 of these Regulations defines exempt work, gives the regulator the power by direction to require an application to be sent to it via a specified method, and also sets out those provisions in relation to which a stop notice under section 35C of that Act may be given. Part 7 also includes consequential amendments to the Regulatory Reform (Fire Safety) Order 2005 (S.I. 2005/1541); the Community Infrastructure Levy Regulations 2010 (S.I. 2010/948); and the Building Safety (Responsible Actors Scheme and Prohibitions) Regulations 2023 (S.I. 2023/753). Schedule 3 to these Regulations sets out transitional, supplementary and saving provisions in relation to projects for higher-risk building work for which plans were deposited or initial notices given before 1st October 2023.
