Unauthorised building work E+W

18.—(1) This regulation applies where it appears to a local authority 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 apply in writing to the local authority for a regularisation certificate in accordance with this regulation, and shall send with the application—

(a) a statement that the application is made in accordance with this regulation,

(b) a description of the unauthorised work,

(c) so far as is reasonably practicable, a plan of the unauthorised work, and

(d) so far as is reasonably practicable, a plan showing any additional work required to be carried out to secure that the unauthorised work complies with the requirements relating to building work in the building regulations which were applicable to that work when it was carried out (in this regulation referred to as “the relevant requirements”).

(3) Where a local authority receive an application in accordance with this regulation, they may require the applicant to take such reasonable steps, including laying open the unauthorised work for inspection by the authority, making tests and taking samples, as the authority think appropriate to ascertain what work, if any, is required to secure that the relevant requirements are met.

(4) When the applicant has taken any such steps required by the local authority as are described in paragraph (3), and having had regard to any direction given in accordance with sections 8 and 9 of, and Schedule 2 to, the Act dispensing with or relaxing a requirement in building regulations which applies to the unauthorised work, the local authority shall notify the applicant—

(a) of the work which in their opinion is required to comply with the relevant requirements or those requirements as dispensed with or relaxed, or

(b) that they cannot determine what work is required to comply with the relevant requirements or those requirements as dispensed with or relaxed, or

(c) that no work is required to secure compliance with the relevant requirements or those requirements as dispensed with or relaxed.

(5) Where the local authority have been able to satisfy themselves, after taking all reasonable steps for that purpose that—

(a) the relevant requirements 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 Act), or

(b) no work is required to secure that the unauthorised work satisfies the relevant requirements (taking account of any such dispensation or relaxation),

they may give a certificate to that effect (in this regulation referred to as “a regularisation certificate”).

(6) A regularisation certificate shall be evidence (but not conclusive evidence) that the relevant requirements specified in the certificate have been complied with.

(7) Where this regulation applies, regulations 12 and 14 shall not apply, and neither the supply of plans nor the taking of any other action in accordance with this regulation is to be treated for the purposes of section 16 of the Act as the deposit of plans in accordance with building regulations.

(8) In this regulation, “unauthorised building work” means building work other than work in relation to which an initial notice, an amendment notice or a public body's notice has effect, which is done without—

(a) a building notice being given to the local authority;

(b) full plans of the work being deposited with the local authority; or

(c) a notice of commencement of work being given, in accordance with regulation 16(1), where a building notice has been given or full plans have been deposited.

Explanatory Note

(This note is not part of the Regulations)

These Regulations revoke and replace the Building Regulations 2000 (S.I. 2000/2531) (“the 2000 Regulations”), and consolidate all subsequent amendments to those Regulations with minor amendments. The amendments include removing the requirement, where building work involves inserting insulation into a cavity wall, to submit along with a building notice a statement about the proposed insulating material. The Regulations also insert into Schedule 3 three new types of work that may be carried out under a self-certification scheme, and revise the list of bodies which are able to register persons for the purposes of self-certification. The three new types of work are the installation of cavity wall insulating material, replacement of roof coverings and installation of systems to produce electricity, heat or cooling by microgeneration or from renewable sources. The authorisation of this last category of work supports the implementation of article 14 of European Parliament and Council Directive 2009/28/EC on the promotion of the use of energy from renewable sources (OJ No. L140, 5.6.2009, p.16).

The Regulations impose requirements on people carrying out “building work” which is defined in regulation 3 as the erection or extension of a building; the provision or extension of a controlled service or fitting; the material alteration of a building or controlled service or fitting; work required in relation to a material change of use; insertion of insulating material into a cavity wall; work involving underpinning of a building; work required to replace or renovate thermal elements; work relating to a change in a building's energy status and work relating to improvement of the energy status of certain large existing buildings. Relevant definitions are found in regulations 2, 3(2) (“material alteration”) and 5 (“material change of use”).

Building work must be carried out so that it complies with the applicable requirements set out in Parts A to P of Schedule 1 and in complying with such requirements there must be no failure to comply with any other such requirements (regulation 4). The requirements in Schedule 1 relate to structure (Part A), fire safety (Part B), site preparation and resistance to contaminants and moisture (Part C), toxic substances (Part D), resistance to the passage of sound (Part E), ventilation (Part F), sanitation, hot water safety and water efficiency (Part G), drainage and waste disposal (Part H), combustion appliances and fuel storage systems (Part J), protection from falling, collision and impact (Part K), conservation of fuel and power (Part L), access to and use of buildings (Part M), glazing – safety in relation to impact, opening and cleaning (Part N) and electrical safety (Part P). Not all provisions of Schedule 1 apply to all building work.

Regulation 7 requires that building work must be carried out with adequate and proper materials and in a workmanlike manner.

Regulations 9 and 10 provide for exemptions. Regulation 11 allows local authorities to dispense with or relax requirements of these Regulations. A person intending to carry out building work is not required to give a building notice or deposit full plans where the work is carried out under a self-certification scheme set out in Schedule 3 or where work falls within Schedule 4 (regulation 12(6)).

Part 3 requires a person intending to carry out building work to give the local authority a building notice or to deposit full plans with the authority (regulation 12) and contains requirements relating to building notices and full plans (regulations 13 and 14) and other procedural requirements.

Part 4 provides that Part 3 and other provisions of these Regulations do not apply where work is supervised in accordance with Part 2 of the Building Act 1984 (c.55) and the Building (Approved Inspectors etc.) Regulations 2010 (S.I. 2010/2215).

Part 5 contains provision about self-certification schemes. Membership of self-certification schemes exempts persons carrying out relevant work from the normal requirements under the Building Regulations to notify the local authority of an intention to carry out the work.

Part 6 contains provision transposing articles 3 to 6 of the Energy Performance of Buildings Directive (OJ No. L1, 4.1.2003, p.65), a transposition note for which is attached to the Explanatory Memorandum for the Building and Approved Inspectors (Amendment) Regulations 2006 (S.I. 2006/652). It also contains other provisions relating to energy performance of buildings.

Part 7 contains provisions relating to the water efficiency of new dwellings.

Part 8 contains provisions about information to be provided by a person carrying out building work to the building owner or responsible person.

Part 9 contains provisions requiring a person carrying out work to test certain sorts of building work and to commission fixed building services.

Part 10 contains miscellaneous provisions including power for local authorities to test building work and take samples, and provision that the contravention of certain regulations is not to be an offence.

Regulation 54 and Schedules 5 and 6 revoke the 2000 Regulations and amending Regulations, including Regulations amending both the 2000 Regulations and the Building (Approved Inspectors etc.) Regulations 2000 (S.I. 2000/2532), and make consequential amendments. No transitional provision is made in respect of the minor changes made in these Regulations. Regulations 49 to 52 contain transitional provisions in respect of the amendments made to the 2000 Regulations by the Building and Approved Inspectors (Amendment) Regulations 2010 (S.I. 2010/719). Regulation 53 secures that transitional and saving provisions in earlier Building Regulations continue to have effect.

A table showing how these Regulations correspond to the 2000 Regulations is attached to the Explanatory Memorandum.
