Do I need building regulations approval if my project is permitted development?

Yes. Permitted development removes the need for planning permission in that case; the building regulations requirements still apply to the construction.

Can my builder handle this?

Some builders arrange a building notice for simpler work. For extensions, a drawn and specified set gives you a more accurate price and a clearer record of what was agreed.

When should this stage start?

Usually after planning is resolved, so the technical work is based on the approved scheme rather than one that may change.

Building regulations drawings

Building regulations are about how a building is constructed, not whether it should exist. This is the technical stage that follows planning, and it is what a builder actually prices and builds from.

Free to start. No obligation. No drawings needed.

What a building regulations set covers

Construction build-ups for walls, floors and roof, including insulation
Structural elements, coordinated with a structural engineer's design
Drainage, including connections and any build-over considerations
Ventilation, heating and energy requirements
Fire safety, escape routes and alarm provision

How approval works

Approval is obtained either through a full plans submission to a building control body before work starts, or through a building notice with inspection during the work. Your designer will explain which suits your project.

Building control inspects at key stages and issues a completion certificate at the end. Keep that certificate - it is asked for when you sell.

Who this is for

Homeowners with planning permission who need the technical stage
People whose project is permitted development and still needs building regulations approval
Anyone whose builder has asked for construction drawings and specifications

Typical process

Scope and fee agreed in writing before the technical stage begins.
Technical drawings and specifications prepared.
Structural design coordinated where it is needed.
Submission to your chosen building control body and response to their comments.

Important things to be aware of

Building regulations approval is separate from planning permission; one does not imply the other.
Building control fees are charged by the building control body and are separate from design fees.
Structural engineering is coordinated with the technical drawings. Structural calculations are included in the Planning & Technical Design and Planning to Tender packages; work beyond the agreed package scope is quoted separately.
