Which postcode districts around Bromley do we cover for permitted development scheme work?
Every Bromley postcode district we draw in, the stock that dominates
it and the authority that validates a permitted development scheme there. Bromley fees below are the
statutory England rates for 2026, not permitted development scheme estimates.
| Postcode | Area | Dominant stock | What it means for a permitted development scheme |
|---|
| BR7 | Chislehurst | 1930s detached, Edwardian villas | Chislehurst sits wholly inside BR7, so Bromley Council validates every permitted development scheme submitted from an BR7 address. |
| BR8 | Swanley | Large 1930s detached and semi-detached in Chislehurst and Bickley; Edwardian in Beckenham; Victorian in Bromley town; Metropolitan Green Belt covers significant rural-fringe land | Permitted development rights in BR8 are read against Kent, not against Bromley. Swanley and Crockenhill sit in Sevenoaks District, so a prior approval or a certificate of lawfulness is submitted to Sevenoaks District Council, and any Article 4 direction that bites there is one Sevenoaks has made. Bromley's directions and its own designations have no effect on a BR8 property. |
| TN16 | Biggin Hill / Downe | 1930s semi-detached | Biggin Hill / Downe sits wholly inside TN16, so Bromley Council validates every permitted development scheme submitted from an TN16 address. |
| SE9 | Eltham / Mottingham | 1930s semi-detached, post-war flats | Eltham / Mottingham is split at SE9. Either Greenwich Council or Bromley Council can determine a permitted development scheme here, so the SE9 address is checked against both policies maps first. |
| SE12 | Lee / Grove Park | Large 1930s detached and semi-detached in Chislehurst and Bickley; Edwardian in Beckenham; Victorian in Bromley town; Metropolitan Green Belt covers significant rural-fringe land | SE12 straddles a boundary: Lee / Grove Park addresses fall to Lewisham Council or Bromley Council, so confirm which authority validates the permitted development scheme before submitting SE12 drawings. |
| SE26 | Sydenham | Victorian villas, Edwardian terraces | SE26 straddles a boundary: Sydenham addresses fall to Lewisham Council or Bromley Council, so confirm which authority validates the permitted development scheme before submitting SE26 drawings. |
| SE20 | Anerley / Penge | Victorian and Edwardian terraces | Anerley / Penge is split at SE20. Either Bromley Council or Croydon Council can determine a permitted development scheme here, so the SE20 address is checked against both policies maps first. |
| BR1 | Bromley / Bickley | Victorian terraces, Edwardian villas, post-war flats | Bromley / Bickley sits wholly inside BR1, so Bromley Council validates every permitted development scheme submitted from an BR1 address. |

How do conservation areas and Article 4 affect a permitted development scheme in Bromley?
Bromley conservation designations: there are 48 across Bromley Council, Beckenham, Keston, Bickley among them. Designation costs a Bromley owner the permitted-development route: a permitted development scheme then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Bickley is the Bromley designation that most often changes a permitted development scheme design.
Article 4 and your Bromley permitted development scheme: Bromley Council has made no borough-wide direction, so permitted development for a permitted development scheme in Bromley generally survives outside Bromley conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a SE20 owner records that a permitted development scheme was lawful.
The building fabric around Bromley: Large 1930s detached and semi-detached in Chislehurst and Bickley; Edwardian in Beckenham; Victorian in Bromley town; Metropolitan Green Belt covers significant rural-fringe land. Largest London borough by area; substantial Green Belt; conservation areas in most town centres; generally permissive elsewhere. A permitted development scheme in Bromley is scoped against that stock first.
Which neighbouring authorities border Bromley?
- Southwark — the Southwark boundary runs against Bromley, so a permitted development scheme a street from Bromley is decided by Southwark Council instead. Southwark runs 43 conservation areas across SE1 and its neighbours, which is why permitted development schemes priced for Bromley are re-checked against Southwark policy whenever the Bromley address sits on that edge.
- Lewisham — adjoining Bromley, with 30 conservation areas centred on SE3. A permitted development scheme on the far side of the Bromley line is determined by Lewisham Council, so the Bromley quote for permitted development schemes is checked against Lewisham guidance before it is issued.
- Greenwich — the Greenwich boundary runs against Bromley, so a permitted development scheme a street from Bromley is decided by Greenwich Council instead. Greenwich runs 20 conservation areas across SE3 and its neighbours, which is why permitted development schemes priced for Bromley are re-checked against Greenwich policy whenever the Bromley address sits on that edge.
- Bexley — cross the Bromley boundary and Bexley Council takes the permitted development scheme instead, applying 16 conservation areas of its own around DA1. We re-price permitted development schemes at the Bromley edge because Bexley policy and Bromley policy rarely align on permitted development scheme depth.
