(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.

Impact Assessments

Impact Assessments generally accompany all UK Government interventions of a regulatory nature that affect the private sector, civil society organisations and public services. They apply regardless of whether the regulation originates from a domestic or international source and can accompany primary (Acts etc) and secondary legislation (SIs). An Impact Assessment allows those with an interest in the policy area to understand:

  • Why the government is proposing to intervene;
  • The main options the government is considering, and which one is preferred;
  • How and to what extent new policies may impact on them; and,
  • The estimated costs and benefits of proposed measures.
