Every Lambeth postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Lambeth fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| SW9 | Brixton / Stockwell | Victorian terraces, post-war estates | Brixton / Stockwell sits wholly inside SW9, so Lambeth Council validates every drawing package submitted from an SW9 address. |
| SW16 | Streatham / Norbury | Edwardian terraces, post-war flats | SW16 straddles a boundary: Streatham / Norbury addresses fall to Lambeth Council or Wandsworth Council or Merton Council or Croydon Council, so confirm which authority validates the drawing package before submitting SW16 drawings. |
| 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. |
| SE19 | Upper Norwood / Crystal Palace | Victorian villas, Edwardian terraces | Upper Norwood / Crystal Palace is split at SE19. Either Croydon Council or Lambeth Council can determine a drawing package here, so the SE19 address is checked against both policies maps first. |
| 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. |
| SW12 | Balham | Victorian and Edwardian terraces | A drawing package in Balham may land with Wandsworth Council or Lambeth Council — SW12 crosses the boundary, and the SW12 policies map decides it street by street. |
| SE11 | Kennington / Vauxhall | Georgian terraces, post-war estates | SE11 covers Kennington / Vauxhall only; Lambeth Council handles the drawing package, and Kennington / Vauxhall case officers apply the SE11 conservation-area map. |
Roof pitch, wall build-up and plot depth change every few Lambeth streets, and each one changes what a drawing package can achieve at that address.
How designation changes a Lambeth drawing package: Lambeth Council maintains 64 conservation areas, including Brixton Road, Kennington, Brockwell Park. Inside any of them a Lambeth drawing 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. Herne Hill sets the tone for Lambeth casework.
What Article 4 removes near Lambeth: Borough-wide Article 4 for HMO conversions; plus office-to-residential restrictions. Before pricing a drawing package we check whether the SE11 address is inside the mapped area, because Lambeth Council draws the Lambeth boundary street by street rather than across the whole of Lambeth.
The building fabric around Lambeth: Victorian terraces in Clapham, Brixton, Herne Hill; Edwardian villas; 1930s and post-war estates in parts of Streatham; Georgian in Kennington. Mix of dense Victorian residential and post-war estate; strong conservation area coverage; generally design-led planning decisions. A drawing package in Lambeth 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 Lambeth Council.

Over the 12 quarters from 2023 Q2 to 2026 Q1, Lambeth decided 1,736 householder planning applications and approved 80.1% of them — 2.9 percentage points below the London average of 83%. That places Lambeth 23rd of 32 London boroughs on householder approval rate. These are decisions the council reported to MHCLG, not our own sample.
| Measure | Lambeth | Context |
|---|---|---|
| Householder applications decided | 1,736 | 77,680 across London |
| Householder approval rate | 80.1% | 83% London average |
| Decided within 8 weeks | 95.2% | 10th fastest of 32 boroughs |
| Took longer than 13 weeks | 0.3% | the applications that overran the statutory target |
| Minor dwellings approval rate | 46.5% | new-build and conversion schemes under 10 units |
| All application types | 75.5% | across 5,139 decisions |
| Certificates of lawfulness issued | 1,138 | confirmations that work was permitted development |
Speed matters as much as the odds. Lambeth decided 95.2% of householder applications inside the eight-week statutory period and let 0.3% 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.
