Every Southwark postcode district we draw in, the stock that dominates it and the authority that validates a building regulations package there. Southwark 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 |
|---|---|---|---|
| SE1 | Bermondsey / Borough / Waterloo | Georgian terraces, post-war flats, new-build | A building regulations package in Bermondsey / Borough / Waterloo may land with Southwark Council or Lambeth Council — SE1 crosses the boundary, and the SE1 policies map decides it street by street. |
| SE5 | Camberwell | Georgian villas, Victorian terraces | Camberwell is split at SE5. Either Southwark Council or Lambeth Council can determine a building regulations package here, so the SE5 address is checked against both policies maps first. |
| SE15 | Peckham / Nunhead | Victorian terraces, post-war estates | A building regulations package at an SE15 address in Peckham / Nunhead is determined by Southwark Council under its own Local Plan policies for Peckham / Nunhead. |
| SE16 | Bermondsey / Rotherhithe | Warehouse conversions, Georgian terraces, new-build | Bermondsey / Rotherhithe sits wholly inside SE16, so Southwark Council validates every building regulations package submitted from an SE16 address. |
| SE17 | Walworth | Post-war estates, new-build towers | SE17 covers Walworth only; Southwark Council handles the building regulations package, and Walworth case officers apply the SE17 conservation-area map. |
| SE21 | Dulwich Village | Georgian villas, Edwardian villas (Dulwich Estate) | SE21 straddles a boundary: Dulwich Village addresses fall to Southwark Council or Lambeth Council, so confirm which authority validates the building regulations package before submitting SE21 drawings. |
| SE22 | East Dulwich | Victorian and Edwardian terraces | East Dulwich sits wholly inside SE22, so Southwark Council validates every building regulations package submitted from an SE22 address. |
| SE24 | Herne Hill | Victorian villas, Edwardian terraces | A building regulations package in Herne Hill may land with Lambeth Council or Southwark Council — SE24 crosses the boundary, and the SE24 policies map decides it street by street. |
Roof pitch, wall build-up and plot depth change every few Southwark streets, and each one changes what a building regulations package can achieve at that address.
Southwark conservation designations: there are 43 across Southwark Council, Camberwell Grove, Bermondsey Street, Dulwich Village among them. Designation costs a Southwark owner the permitted-development route: a building regulations package then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Borough is the Southwark designation that most often changes a building regulations package design.
Article 4 and your Southwark building regulations package: Article 4 for HMOs borough-wide; additional Article 4 for office-to-residential in Bermondsey and Elephant & Castle. At a SE1 address that matters twice over, because Southwark Council applies the direction unevenly across Southwark — we read the Southwark policies map for the exact SE1 address before quoting building regulations drawings.
The building fabric around Southwark: Georgian and Regency in Bermondsey and Borough; Victorian terraces in Camberwell and Peckham; Dulwich Estate controlled housing; riverside new-build. Dulwich Estate private planning scheme affects much of SE21 and SE22; Southwark planning for rest of borough; strong heritage context. A building regulations package in Southwark 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 Southwark Council.

Direct answers to the questions Southwark homeowners ask every week about building regulations drawings.
Start a free quote →In Southwark, you can submit building regulations applications to either Southwark 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 Southwark 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 Southwark (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 Southwark 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, Southwark 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 Southwark, 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 Southwark 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 Southwark 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.
