Where in Brent does a scheme inside an Article 4 area actually get determined?
Below: the postcode districts we draw in across Brent, the stock that fills them, and which council validates a submission from each. One caution about the right-hand column — it lists the statutory planning charge set by government for 2026, which has nothing to do with what drawings cost.
| Postcode | Area | Dominant stock | What it means for a scheme inside an Article 4 area |
|---|
| NW2 | Cricklewood / Neasden | Edwardian villas and terraces | NW2, taking in Cricklewood and Neasden, is split three ways. An address there may be determined by Brent, by Barnet or by Camden, so establish which authority validates the drawings before they are submitted. |
| NW10 | Willesden / Harlesden / Kensal Green | Modern apartments, post-war estates | NW10 takes in Willesden, Harlesden and Kensal Green, and it crosses into Ealing on its western side. Confirm whether Brent or Ealing holds the address before an NW10 submission goes in. |
| HA0 | Wembley / Sudbury | 1930s semi-detached, new-build | HA0 covers the Sudbury side of Wembley, and submissions from an HA0 address are likewise validated by Brent Council. |
| HA9 | Wembley / Wembley Park | 1930s semi-detached, new-build | Wembley and Wembley Park lie inside HA9, and Brent Council validates every submission made from an HA9 address. |
| NW6 | Kilburn / West Hampstead / Queen's Park | Mansion blocks, post-war flats | NW6 straddles a boundary: Kilburn / West Hampstead / Queen's Park addresses fall to Camden Council or Brent Council, so confirm which authority validates the scheme inside an Article 4 area before submitting NW6 drawings. |
| NW9 | Colindale / Kingsbury | Post-war flats, new-build | Colindale / Kingsbury is split at NW9. Either Barnet Council or Brent Council can determine a scheme inside an Article 4 area here, so the NW9 address is checked against both policies maps first. |

How do conservation areas and Article 4 affect a scheme inside an Article 4 area in Brent?
Conservation areas covering Brent: 22 of them, with Mapesbury, Kensal Green and Harlesden the names owners here run into most. Inside a conservation area the permitted development route closes, so the submission becomes a householder application decided over eight weeks rather than a prior approval decided in six, and the charge changes with it. The householder application fee in England is £548. The fee for a larger householder prior approval is £249. None of that means a refusal is coming, though this is a harder borough than the average: across twelve quarters ending last March, 2,231 of 2,843 householder applications were granted, which is 78.5% where the 33 boroughs pooled reach 83.0%. Six hundred and twelve householder schemes were turned down in that period. Source: MHCLG live planning statistics

Ealing runs 30 conservation areas across W3 and its neighbours, which is why scheme inside an Article 4 areas priced for Brent are re-checked against Ealing policy whenever the Brent address sits on that edge.
- Harrow — adjoining Brent, with 29 conservation areas centred on HA1. A scheme inside an Article 4 area on the far side of the Brent line is determined by Harrow Council, so the Brent quote for scheme inside an Article 4 areas is checked against Harrow guidance before it is issued.
