Every BR2 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. BR2 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| BR2 | Hayes / Keston | Victorian terraces, Edwardian villas, post-war flats | Hayes / Keston sits wholly inside BR2, so Bromley Council validates every drawing package submitted from an BR2 address. |
| BR2 | Bromley | Victorian terraces, Edwardian villas, post-war flats | Bromley sits inside BR2; drawing package proposals here are determined by Bromley Council. |
| BR2 | Keston | Edwardian villas, 1930s semi-detached | Keston sits inside BR2; drawing package proposals here are determined by Bromley Council. |
| SE20 | Anerley / Penge | Victorian and Edwardian terraces | Adjoining district to BR2, also inside Bromley for drawing package purposes. |
| BR1 | Bromley / Bickley | Victorian terraces, Edwardian villas, post-war flats | Adjoining district to BR2, also inside Bromley for drawing package purposes. |
| BR3 | Beckenham | Edwardian villas, 1930s semi-detached | Adjoining district to BR2, also inside Bromley for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few BR2 streets, and each one changes what a drawing package can achieve at that address.
