End-to-end Party Wall Act 1996 service for Bromley — Section 1, 3 and 6 notices, schedule of condition surveys, party wall award coordination. We handle the process so your Bromley build starts without neighbour disputes.
Two months before cutting into a shared wall, one month before building at the boundary or excavating within three metres of a neighbour’s foundations. On a Bromley semi that is one set of notices; on a terrace it is two, one for each party wall.

| Section 6(2) | Excavating within 6m, inside a 45-degree line | 1 month |

Sources: the Party Wall etc. Act 1996, sections 1, 2, 6 and 10, read at 1 September 2026; Bromley decision figures from MHCLG District Planning Application Statistics (PS1 and PS2), twelve quarters to March 2026. Surveyors’ fees under a section 10 award are not on a statutory scale; they are agreed between the appointed surveyors, and the building owner normally pays both.

Every Bromley postcode district we draw in, the stock that dominates it and the authority that validates a party wall package there. Bromley fees below are the statutory England rates for 2026, not party wall package estimates.
| Postcode | Area | Dominant stock | What it means for a party wall package |
|---|---|---|---|
| TN16 | Biggin Hill / Downe | 1930s semi-detached | A party wall package at an TN16 address in Biggin Hill / Downe is determined by Bromley Council under its own Local Plan policies for Biggin Hill / Downe. |
| SE9 | Eltham / Mottingham | 1930s semi-detached, post-war flats | Eltham / Mottingham is split at SE9. Either Greenwich Council or Bromley Council can determine a party wall package 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 | Lee / Grove Park is split at SE12. Either Lewisham Council or Bromley Council can determine a party wall package here, so the SE12 address is checked against both policies maps first. |
| SE26 | Sydenham | Victorian villas, Edwardian terraces | Sydenham is split at SE26. Either Lewisham Council or Bromley Council can determine a party wall package here, so the SE26 address is checked against both policies maps first. |
| SE20 | Anerley / Penge | Victorian and Edwardian terraces | A party wall package in Anerley / Penge may land with Bromley Council or Croydon Council — SE20 crosses the boundary, and the SE20 policies map decides it street by street. |
| BR1 | Bromley / Bickley | Victorian terraces, Edwardian villas, post-war flats | Bromley / Bickley sits wholly inside BR1, so Bromley Council validates every party wall package submitted from an BR1 address. |
| BR2 | Hayes / Keston | Victorian terraces, Edwardian villas, post-war flats | Hayes / Keston sits wholly inside BR2, so Bromley Council validates every party wall package submitted from an BR2 address. |
| BR3 | Beckenham | Edwardian villas, 1930s semi-detached | Beckenham sits wholly inside BR3, so Bromley Council validates every party wall package submitted from an BR3 address. |
Roof pitch, wall build-up and plot depth change every few Bromley streets, and each one changes what a party wall package can achieve at that address.
How designation changes a Bromley party wall package: Bromley Council maintains 48 conservation areas, including Bromley Town, Chislehurst, Beckenham. Inside any of them a Bromley party wall 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. Keston sets the tone for Bromley casework.
Bromley permitted development status: there is no borough-wide direction from Bromley Council, so a party wall package at a SE20 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a Bromley sale to argue it later.
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 party wall package in Bromley 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 Bromley Council.

Direct answers to the questions Bromley homeowners ask every week about party wall services.
Start a free quote →You need Party Wall Act notices if your Bromley project involves: building on or astride a boundary (Section 1), cutting into a party wall or party structure (Section 3), or excavating within 3m/6m of an adjoining property's foundations (Section 6). Most loft conversions, extensions and basement digs in Bromley trigger at least one section.
If your neighbour consents, that is the whole cost. If they dissent, surveyors must be appointed for the Award and their fees are additional, per neighbour. Notices are included in our Complete architectural packages at no extra charge. See our fees.
If all adjoining owners in Bromley consent: 14 days (Section 3/6 notice) or 1 month (Section 1 notice). If they dissent and surveyors must be appointed, allow 6–8 weeks for the Award. We serve notices as early as possible so the process runs in parallel with your planning application.
No — starting notifiable works in Bromley before serving valid notices or obtaining a Party Wall Award is a breach of the Party Wall Act 1996. It can result in injunctions, damages and loss of your statutory protections. We ensure notices are served at the right time so your build timeline is not delayed.
If an adjoining owner in Bromley does not respond within 14 days, the Act deems them to have dissented. This triggers the surveyor appointment process — you appoint a surveyor, they can appoint their own (at your cost) or you can agree on a single 'agreed surveyor'. We manage this process and keep it moving.
