Which Brent postcodes does this conservation area application service cover?
Brent district by district: the postcodes we draw in, what stands in each of them, and which authority takes a conservation area application at that address. The charges shown are the 2026 statutory England fees, not an estimate of what a conservation-area scheme costs.
| Postcode | Area | Dominant stock | What it means for a conservation area application |
|---|
| NW2 | Cricklewood / Neasden | Edwardian villas and terraces | NW2 straddles a boundary: Cricklewood / Neasden addresses fall to Brent Council or Barnet Council or Camden Council, so confirm which authority validates the conservation area application before submitting NW2 drawings. |
| NW10 | Willesden / Harlesden / Kensal Green | Modern apartments, post-war estates | NW10 crosses an authority boundary: Willesden, Harlesden and Kensal Green addresses fall to Brent Council or to Ealing Council depending on the street, so establish which one validates before NW10 conservation area drawings go in. |
| HA0 | Wembley / Sudbury | 1930s semi-detached, new-build | HA0, covering Wembley and Sudbury, is entirely Brent Council territory, and the Local Plan policies written for those areas govern the outcome. |
| HA9 | Wembley / Wembley Park | 1930s semi-detached, new-build | An HA9 address in Wembley or Wembley Park is decided by Brent Council alone, under the Local Plan policies it applies to that part of the borough. |
| NW6 | Kilburn / West Hampstead / Queen's Park | Mansion blocks, post-war flats | Kilburn / West Hampstead / Queen's Park is split at NW6. Either Camden Council or Brent Council can determine a conservation area application here, so the NW6 address is checked against both policies maps first. |
| NW9 | Colindale / Kingsbury | Post-war flats, new-build | NW9 is split as well. Colindale and Kingsbury addresses sit with Barnet Council or with Brent Council according to the street, so the validating authority needs confirming before an NW9 application is lodged. |
How does a conservation area application differ street by street across Brent?
Roof form, wall build-up and plot depth shift from one Brent street to the next, and inside a conservation area each of those variations is also part of the evidence a case officer weighs.
- Mapesbury (NW2) — a conservation area application in Mapesbury starts from edwardian villas and terraces, and Mapesbury reads as Edwardian conservation area. Edwardian houses here typically need the same householder set plus a roof plan where a dormer is proposed in NW2. Brent Council assesses Mapesbury conservation area applications against its own Mapesbury character guidance, and the location plan we draw for Mapesbury references Mapesbury Conservation Area.
- Kensal Green (NW10) — a conservation area application in Kensal Green starts from victorian terraces, and Kensal Green reads as Victorian terraces. Most applications on these Victorian streets are householder applications validated on existing and proposed plans in NW10.

Brent Council assesses Willesden conservation area applications against its own Willesden character guidance, and the location plan we draw for Willesden references Willesden Green Tube.
- Neasden (NW10, NW2) — 1930s semi-detached defines Neasden, where 1930s semi-detached, post-war set what a conservation area application can do. On these 1930s semis the prior approval route often replaces a full application across NW10. Any Neasden conservation area application is validated by Brent Council, with BAPS Shri Swaminarayan Mandir the usual Neasden reference point on the site plan.
- Cricklewood (NW2) — a conservation area application in Cricklewood starts from edwardian terraces, and Cricklewood reads as Edwardian terraces.

What local planning policy applies to a conservation area application in Brent?
Brent conservation designations: these were not designated as a set and do not behave as one. The oldest is Roe Green Village, protected on 31 October 1968; the newest is Kensal Rise, added on 27 May 2024 — a fifty-six year span, over which what designation was meant to achieve changed considerably. They differ as much in size: Queens Park covers 54.6 hectares, while Sudbury Cottages covers 0.4, and a rule written for a whole Edwardian suburb reads very differently when it is applied to a single terrace of cottages. Twenty-three are recorded for Brent in the national dataset. What designation costs is the same in each: the permitted development route closes, so work that would have gone through prior approval at £249 in six weeks needs a £548 householder application with eight weeks to decide. Harlesden is the designation that most often changes a scheme here.
Brent and Article 4: Article 4 for HMO conversions in specific streets around Wembley and Harlesden. A conservation area application planned at a NW2 address is checked against that direction first; Brent Council publishes the Brent extent, and the NW2 line rarely follows the Brent boundary you would expect.
What Brent is built from: Edwardian villas in Queen's Park and Mapesbury; Victorian terraces in Kilburn and Harlesden; 1930s semi-detached in Wembley; post-war tower blocks in Church End. Highly diverse borough; Queen's Park and Mapesbury are heritage-controlled; Wembley is a major regeneration hub. That mix decides the conservation area application route in Brent more than the postcode does.
Which neighbouring authorities border Brent?
- Hammersmith and Fulham — adjoining Brent, with 45 conservation areas centred on W6. A conservation area application on the far side of the Brent line is determined by Hammersmith & Fulham Council, so the Brent quote for conservation area applications is checked against Hammersmith and Fulham guidance before it is issued.
- Ealing — cross the Brent boundary and Ealing Council takes the conservation area application instead, applying 30 conservation areas of its own around W3. We re-price conservation area applications at the Brent edge because Ealing policy and Brent policy rarely align on conservation area application depth.
- Harrow — cross the Brent boundary and Harrow Council takes the conservation area application instead, applying 29 conservation areas of its own around HA1. We re-price conservation area applications at the Brent edge because Harrow policy and Brent policy rarely align on conservation area application depth.
- Barnet — the Barnet boundary runs against Brent, so a conservation area application a street from Brent is decided by Barnet Council instead. Barnet runs 20 conservation areas across N2 and its neighbours, which is why conservation area applications priced for Brent are re-checked against Barnet policy whenever the Brent address sits on that edge.
