Every Southwark postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Southwark fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| SE1 | Bermondsey / Borough / Waterloo | Georgian terraces, post-war flats, new-build | Bermondsey / Borough / Waterloo is split at SE1. Either Southwark Council or Lambeth Council can determine a drawing package here, so the SE1 address is checked against both policies maps first. |
| SE5 | Camberwell | Georgian villas, Victorian terraces | A drawing package in Camberwell may land with Southwark Council or Lambeth Council — SE5 crosses the boundary, and the SE5 policies map decides it street by street. |
| SE15 | Peckham / Nunhead | Victorian terraces, post-war estates | A drawing 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 | SE16 covers Bermondsey / Rotherhithe only; Southwark Council handles the drawing package, and Bermondsey / Rotherhithe case officers apply the SE16 conservation-area map. |
| SE17 | Walworth | Post-war estates, new-build towers | A drawing package at an SE17 address in Walworth is determined by Southwark Council under its own Local Plan policies for Walworth. |
| SE21 | Dulwich Village | Georgian villas, Edwardian villas (Dulwich Estate) | Dulwich Village is split at SE21. Either Southwark Council or Lambeth Council can determine a drawing package here, so the SE21 address is checked against both policies maps first. |
| SE22 | East Dulwich | Victorian and Edwardian terraces | SE22 covers East Dulwich only; Southwark Council handles the drawing package, and East Dulwich case officers apply the SE22 conservation-area map. |
| SE24 | Herne Hill | Victorian villas, Edwardian terraces | Herne Hill is split at SE24. Either Lambeth Council or Southwark Council can determine a drawing package here, so the SE24 address is checked against both policies maps first. |
Roof pitch, wall build-up and plot depth change every few Southwark streets, and each one changes what a drawing package can achieve at that address.
Southwark conservation designations: there are 43 across Southwark Council, Peckham Rye, Borough, Camberwell Grove among them. Designation costs a Southwark owner the permitted-development route: a drawing package then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Dulwich Village is the Southwark designation that most often changes a drawing package design.
Article 4 and your Southwark drawing 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 architectural 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 drawing 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.

Over the 12 quarters from 2023 Q2 to 2026 Q1, Southwark decided 1,617 householder planning applications and approved 93.8% of them — 10.8 percentage points above the London average of 83%. That places Southwark 2nd of 32 London boroughs on householder approval rate. These are decisions the council reported to MHCLG, not our own sample.
| Measure | Southwark | Context |
|---|---|---|
| Householder applications decided | 1,617 | 77,680 across London |
| Householder approval rate | 93.8% | 83% London average |
| Decided within 8 weeks | 95.8% | 8th fastest of 32 boroughs |
| Took longer than 13 weeks | 1.2% | the applications that overran the statutory target |
| Minor dwellings approval rate | 88.0% | new-build and conversion schemes under 10 units |
| All application types | 90.6% | across 4,303 decisions |
| Certificates of lawfulness issued | 604 | confirmations that work was permitted development |
Speed matters as much as the odds. Southwark decided 95.8% of householder applications inside the eight-week statutory period and let 1.2% run past thirteen weeks. A drawing package that is complete and correctly described at validation is the part of that timeline you control; the rest belongs to the council's caseload.
