Every Bexley postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Bexley fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| DA8 | Erith | Victorian terraces, post-war estates | A drawing package at an DA8 address in Erith is determined by Bexley Council under its own Local Plan policies for Erith. |
| DA14 | Sidcup | 1930s semi-detached, Edwardian villas | A drawing package at an DA14 address in Sidcup is determined by Bexley Council under its own Local Plan policies for Sidcup. |
| DA16 | Welling | 1930s semi-detached | Welling sits wholly inside DA16, so Bexley Council validates every drawing package submitted from an DA16 address. |
| DA17 | Belvedere | 1930s semi-detached, post-war flats | A drawing package at an DA17 address in Belvedere is determined by Bexley Council under its own Local Plan policies for Belvedere. |
| DA18 | Erith Marshes | 1930s semi-detached dominates; Victorian cottages in Bexley Village and Crayford; post-war estates in Thamesmead and Erith | DA18 covers Erith Marshes only; Bexley Council handles the drawing package, and Erith Marshes case officers apply the DA18 conservation-area map. |
| SE2 | Abbey Wood | 1930s semi-detached dominates; Victorian cottages in Bexley Village and Crayford; post-war estates in Thamesmead and Erith | Abbey Wood is split at SE2. Either Greenwich Council or Bexley Council can determine a drawing package here, so the SE2 address is checked against both policies maps first. |
| DA1 | Crayford / Dartford fringe | Victorian terraces, 1930s semi-detached | A drawing package at an DA1 address in Crayford / Dartford fringe is determined by Bexley Council under its own Local Plan policies for Crayford / Dartford fringe. |
Roof pitch, wall build-up and plot depth change every few Bexley streets, and each one changes what a drawing package can achieve at that address.
Conservation areas covering Bexley: Bexley Council runs 16, and Welling, Bexley Village, Old Bexley are the ones Bexley owners meet most. A drawing package inside a Bexley conservation area loses permitted development, so the Bexley submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Bexley Village a drawing package is judged on the street elevation first.
No blanket Article 4 over Bexley: Bexley Council has not withdrawn permitted development across Bexley, so a drawing package outside a Bexley conservation area usually keeps it. The £274 Lawful Development Certificate is still the document a DA1 owner wants on file.
What Bexley is built from: 1930s semi-detached dominates; Victorian cottages in Bexley Village and Crayford; post-war estates in Thamesmead and Erith. Outer south-east London suburban; very permissive planning environment; strong PD uptake for extensions and loft conversions. That mix decides the drawing package route in Bexley more than the postcode does, and it is what a Bexley Council case officer reads first. A householder application costs £548 paid to Bexley Council direct, with 8 weeks to a decision once validated.

Over the 12 quarters from 2023 Q2 to 2026 Q1, Bexley decided 2,859 householder planning applications and approved 91.7% of them — 8.7 percentage points above the London average of 83%. That places Bexley 3rd of 32 London boroughs on householder approval rate. These are decisions the council reported to MHCLG, not our own sample.
| Measure | Bexley | Context |
|---|---|---|
| Householder applications decided | 2,859 | 77,680 across London |
| Householder approval rate | 91.7% | 83% London average |
| Decided within 8 weeks | 97.9% | 4th fastest of 32 boroughs |
| Took longer than 13 weeks | 0.9% | the applications that overran the statutory target |
| Minor dwellings approval rate | 64.1% | new-build and conversion schemes under 10 units |
| All application types | 87.1% | across 3,938 decisions |
| Certificates of lawfulness issued | 882 | confirmations that work was permitted development |
Speed matters as much as the odds. Bexley decided 97.9% of householder applications inside the eight-week statutory period and let 0.9% 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.
