Submit a full plans application
This is the most thorough option and gives you most protection. If we're satisfied your application meets our building regulation standards, we'll send you an 'approval notice'.
The approval is valid for three years. Work can begin as soon as two days after you've submitted your application, but you cannot be certain that any work carried out before you have got formal approval complies with building regulations. If you also need planning permission, do not start work until you've got this.
With your application, you'll need to include:
- all detailed plans, sections and elevations, incorporating all necessary technical notes, supporting calculations and specifications
- a 1:1250 scale plan showing the size and position of the building, or the building as extended, and its relationship to adjoining boundaries (sometimes known as 'block plans')
- The appropriate payment
You'll get a response from us within 15 days.
