What Bromley Council asks of a building regulations application

From the council's Building control regulation approval: Full Plans approval (adopted current council pages, read 25 October 2026).

  • Bromley says its Full Plans procedure suits new buildings, extensions or alterations other than small single storey domestic extensions, extensive internal structural alterations and loft conversions. (source, checked 25 October 2026)
  • A Full Plans application needs fully detailed plans, specifications, calculations and other supporting details, scaled to the size and type of work, with a location plan showing the building relative to neighbouring roads and a Client Authorisation form where an agent applies. (source, checked 25 October 2026)
  • If the work complies, Bromley issues an approval notice within five weeks or, where extended by agreement, two months, and it may add conditions to an approval with your written agreement. (source, checked 25 October 2026)
  • On completion the person doing the work must submit a Notice of Completion when requesting a completion inspection, and without that form Bromley cannot issue a Completion Certificate. (source, checked 25 October 2026)
  • Applications received on or after 15 June 2022 for new dwellings, extensions and alterations are subject to the revised Part F and Part L regulations, and Bromley says a Full Plans approval can help when borrowing from a lender and give builders an accurate quote. (source, checked 25 October 2026)

What Bromley building regulations application drawings have to show

Bromley names loft conversions and structural alterations as full plans work, so for a typical Bromley loft the set includes the structure, staircase, fire escape and insulation details, with the calculations beside them. The location plan shows the house against the neighbouring roads, and the Client Authorisation form is completed when we submit on your behalf.

The construction drawings also show the Part F ventilation and Part L energy details required for applications since 15 June 2022, so that the approval notice is issued within the five weeks (or two months by agreement) Bromley allows. We remind you that the Notice of Completion is yours to submit at the end.

Answers

Bromley building regulations application questions

Which Bromley building work needs a Full Plans application?
Bromley says Full Plans suits new buildings, extensions or alterations other than small single storey domestic extensions, extensive internal structural alterations and loft conversions. Smaller domestic jobs can go through a building notice instead. We advise which route fits your project before preparing the drawings.
What is a Notice of Completion in Bromley?
It is the form you submit when you request a completion inspection. Bromley says without it the council cannot issue a Completion Certificate. The person doing the work is also legally obliged to notify the council of work stages, which its acknowledgement letter sets out.
Do the 2022 building regulation changes affect Bromley applications?
Yes. Bromley says applications received on or after 15 June 2022 for new dwellings, extensions and alterations are subject to the revised regulations, with downloadable guides on Parts F and L. Our construction drawings and specification are prepared to those standards.
