Every Bromley postcode district we draw in, the stock that dominates it and the authority that validates a building regulations package there. Bromley fees below are the statutory England rates for 2026, not building regulations package estimates.
| Postcode | Area | Dominant stock | What it means for a building regulations package |
|---|---|---|---|
| BR5 | Orpington / Petts Wood | 1930s semi-detached | Orpington / Petts Wood sits wholly inside BR5, so Bromley Council validates every building regulations package submitted from an BR5 address. |
| BR6 | Orpington | 1930s semi-detached | BR6 covers Orpington only; Bromley Council handles the building regulations package, and Orpington case officers apply the BR6 conservation-area map. |
| BR7 | Chislehurst | 1930s detached, Edwardian villas | A building regulations package at an BR7 address in Chislehurst is determined by Bromley Council under its own Local Plan policies for Chislehurst. |
| BR8 | Swanley | Large 1930s detached and semi-detached in Chislehurst and Bickley; Edwardian in Beckenham; Victorian in Bromley town; Metropolitan Green Belt covers significant rural-fringe land | BR8 covers Swanley only; Bromley Council handles the building regulations package, and Swanley case officers apply the BR8 conservation-area map. |
| TN16 | Biggin Hill / Downe | 1930s semi-detached | Biggin Hill / Downe sits wholly inside TN16, so Bromley Council validates every building regulations package submitted from an TN16 address. |
| SE9 | Eltham / Mottingham | 1930s semi-detached, post-war flats | SE9 straddles a boundary: Eltham / Mottingham addresses fall to Greenwich Council or Bromley Council, so confirm which authority validates the building regulations package before submitting SE9 drawings. |
| SE12 | Lee / Grove Park | Large 1930s detached and semi-detached in Chislehurst and Bickley; Edwardian in Beckenham; Victorian in Bromley town; Metropolitan Green Belt covers significant rural-fringe land | Lee / Grove Park is split at SE12. Either Lewisham Council or Bromley Council can determine a building regulations package here, so the SE12 address is checked against both policies maps first. |
| SE26 | Sydenham | Victorian villas, Edwardian terraces | Sydenham is split at SE26. Either Lewisham Council or Bromley Council can determine a building regulations package here, so the SE26 address is checked against both policies maps first. |
Roof pitch, wall build-up and plot depth change every few Bromley streets, and each one changes what a building regulations package can achieve at that address.
How designation changes a Bromley building regulations package: Bromley Council maintains 48 conservation areas, including Keston, Bickley, Bromley Town. Inside any of them a Bromley building regulations package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Chislehurst sets the tone for Bromley casework.
No blanket Article 4 over Bromley: Bromley Council has not withdrawn permitted development across Bromley, so a building regulations package outside a Bromley conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a SE20 owner wants on file.
The building fabric around Bromley: Large 1930s detached and semi-detached in Chislehurst and Bickley; Edwardian in Beckenham; Victorian in Bromley town; Metropolitan Green Belt covers significant rural-fringe land. Largest London borough by area; substantial Green Belt; conservation areas in most town centres; generally permissive elsewhere. A building regulations package in Bromley is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Bromley Council.

Direct answers to the questions Bromley homeowners ask every week about building regulations drawings.
Start a free quote →In Bromley, you can submit building regulations applications to either Bromley Council's in-house Building Control (LABC route) or to a private approved inspector. Both routes produce the same legally-valid completion certificate. We submit to whichever suits your project and builder.
The building regulations fee for a Bromley project is set by scope: a straightforward extension or loft is the baseline, while HMOs, basement conversions and flat splits need more detailing and coordination. Structural calculations are priced by the intervention — a single beam is far less than a full loft or underpinning package. See our fees.
Yes — every habitable loft conversion in Bromley (and across England) requires Building Regulations approval covering fire escape, floor structure, insulation and staircase. This is independent of whether you also need planning permission.
Part L of the Building Regulations sets minimum energy-efficiency standards — insulation, glazing U-values, air permeability, heating efficiency. New extensions in Bromley must meet the 2025 uplift (Future Homes Standard transition). We include full Part L calculations and a compliance statement in every Complete package.
Once submitted, Bromley Council Building Control reviews Full Plans within 5–8 weeks. Approved inspectors typically review in 2–4 weeks. On-site inspections run through the build — typically 6–10 visits depending on scope.
In Bromley, building regulations are required for: loft conversions, extensions, structural alterations, roof replacements, new openings in walls, and any work to a flat. Some minor works (like-for-like replacements, small porches) are exempt. We confirm at the free site visit.
A completion certificate from Bromley Council Building Control (or an approved inspector) confirms your works comply with Building Regulations. It is essential for selling or re-mortgaging — lenders and conveyancers require it. We manage the inspection sequence and close out sign-off as part of every Complete package.
Extensions and loft conversions in Bromley that change the building's energy characteristics require an updated EPC (or SAP/SBEM calculation as part of Part L compliance). We include Part L calculations in every Complete and Bespoke package.
