Applying for Building Control approval is a necessary step before starting most types of notifiable building work. The process is straightforward for most residential projects and can be completed online or by post, with the key decision being whether to submit a full plans application or a building notice.

Two Application Routes

Full plans application

A full plans application involves submitting detailed drawings and specifications to the Building Control body for approval before work begins. The Building Control officer reviews the plans and either approves them, requires amendments, or rejects them. Once approved, the plans provide a clear specification for the work and a basis for the stage inspections during construction. A full plans application is recommended for complex projects, new builds, or any project where having approved drawings provides useful certainty.

Building notice

A building notice allows work to start within two days of submission without the need for pre-approval of drawings. The notice is submitted with basic information about the project and the applicant, a site plan, and the fee. The Building Control officer then carries out stage inspections during construction to verify compliance. A building notice is suitable for simpler projects where the construction is well understood by the contractor. It does not provide the security of approved drawings but is quicker and simpler for straightforward works.

How to Submit

Most local authorities now accept Building Control applications through their online portals. The application form, site plan, and any required drawings are uploaded digitally and the fee paid online. Paper applications are still accepted by most authorities. The application must be made to the local authority in whose area the building is located, not to the applicant's home local authority if these are different.

Alternatively, a private Approved Inspector can be appointed to carry out the Building Control function. The initial notice to the local authority is submitted jointly by the Approved Inspector and the building owner, which discharges the local authority's involvement in the matter. An Approved Inspector may offer a faster or more tailored service for commercial or larger residential projects.

What Information Is Required

A building notice requires the address of the building, a description of the proposed work, the applicant's name and contact details, a site plan showing the building's location and the work proposed, and confirmation of whether the building is a dwelling. A full plans application additionally requires drawings showing the design of the works to a sufficient level of detail for the Building Control officer to assess compliance with the relevant regulations.

Summary

Building Control applications are submitted to the local authority or an Approved Inspector using a full plans application or a building notice. Full plans provide pre-construction approval of the design; a building notice allows work to start quickly without drawing approval. Applications are submitted online or by post with the required fee. Competent persons scheme contractors self-certify eligible work and notify Building Control directly.
