Which Bexley postcodes does this drawing package service cover?

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.

PostcodeAreaDominant stockWhat it means for a drawing package
DA8ErithVictorian terraces, post-war estatesA drawing package at an DA8 address in Erith is determined by Bexley Council under its own Local Plan policies for Erith.
DA14Sidcup1930s semi-detached, Edwardian villasA drawing package at an DA14 address in Sidcup is determined by Bexley Council under its own Local Plan policies for Sidcup.
DA16Welling1930s semi-detachedWelling sits wholly inside DA16, so Bexley Council validates every drawing package submitted from an DA16 address.
DA17Belvedere1930s semi-detached, post-war flatsA drawing package at an DA17 address in Belvedere is determined by Bexley Council under its own Local Plan policies for Belvedere.
DA18Erith Marshes1930s semi-detached dominates; Victorian cottages in Bexley Village and Crayford; post-war estates in Thamesmead and ErithDA18 covers Erith Marshes only; Bexley Council handles the drawing package, and Erith Marshes case officers apply the DA18 conservation-area map.
SE2Abbey Wood1930s semi-detached dominates; Victorian cottages in Bexley Village and Crayford; post-war estates in Thamesmead and ErithAbbey 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.
DA1Crayford / Dartford fringeVictorian terraces, 1930s semi-detachedA 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.

How does a drawing package differ street by street across Bexley?

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.

What local planning policy applies to a drawing package in Bexley?

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.

Who decides a drawing package on the edge of Bexley?

Sources for this Bexley drawing package page: borough policies maps and conservation-area registers (2025–26), Royal Mail postcode district boundaries, the Town and Country Planning (Fees for Applications) (England) Regulations, the Town and Country Planning (General Permitted Development) (England) Order 2015 as amended, and the Party Wall etc. Act 1996.

What are the chances of approval in Bexley?

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.

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.
