Which postcode districts around Ealing do we cover for measured building survey work?
Listed below are the Ealing postcode districts we draw in, the stock that predominates in each, and whichever authority would validate a survey-led submission sent from there. The money column is statute rather than our quote — £548 for a householder application, £249 for larger home extension prior approval and £274 for a certificate, at the England rates in force from 1 April 2026.
| Postcode | Area | Dominant stock | What it means for a measured building survey |
|---|
| W7 | Hanwell | Edwardian villas, 1930s semi-detached | W7 covers Hanwell only; Ealing Council handles the measured building survey. |
| W13 | West Ealing | Edwardian terraces | No permission is sought and none is given. Measurement is judged on whether later drawings fit reality. West Ealing's W13 villas are frequently split into flats, which means communal halls, meter cupboards and the party wall line all belong in the record alongside the rooms themselves. |
| UB1 | Southall North | Edwardian terraces, post-war flats | Nothing is determined at this stage. A surveyor measures, an owner receives the drawings, and only a later application meets a planning officer. In Southall North the UB1 houses have often been extended more than once, so the survey becomes a job of finding where the original back wall used to be. |
| UB2 | Southall South | Edwardian terraces, post-war flats | There is no approving authority for measurement; accuracy and completeness are what govern it. UB2 in Southall South mixes terraces with small workshops and mixed-use frontages, and a shop underneath a flat means two circulation routes and two sets of levels to reconcile in the same drawing. |
| UB5 | Northolt | 1930s semi-detached, post-war estates | UB5 covers Northolt only; Ealing Council handles the measured building survey. |
| UB6 | Greenford / Perivale | 1930s semi-detached | UB6 covers Greenford / Perivale only; Ealing Council handles the measured building survey. |
| NW10 | Willesden / Harlesden / Kensal Green | Modern apartments, post-war estates | NW10 runs across the Brent boundary through Willesden, Harlesden and Kensal Green, so a survey drawn for an NW10 address may be validated by Brent Council or by Ealing Council. The NW10 policies map settles it street by street, and we check it before the visit. |
| W4 | Chiswick / Bedford Park | Arts & Crafts villas (listed) | W4 is shared with Hounslow across Chiswick and Bedford Park. We confirm which of the two councils holds a W4 address on its list before drawings go out, because their validation requirements are not identical. |

How do conservation areas and Article 4 affect a measured building survey in Ealing?
Conservation areas covering Ealing: Ealing Council runs 30, and Bedford Park, Acton Green, Hanwell are the ones Ealing owners meet most. A measured building survey inside a Ealing conservation area loses permitted development, so the Ealing submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Hanwell a measured building survey is judged on the street elevation first.
Article 4 and your Ealing measured building survey: Article 4 for HMOs in specific streets in Acton, Ealing and Southall. At a W3 address that matters twice over, because Ealing Council applies the direction unevenly across Ealing — we read the Ealing policies map for the exact W3 address before quoting measured building surveys.
What Ealing is built from: Victorian and Edwardian villas in Ealing central; 1930s semi-detached in Northolt and Hanwell; mansion blocks along main roads; Bedford Park is a listed Arts & Crafts garden suburb. Leafy outer-west London; Bedford Park conservation area has strict heritage controls; rest of borough generally permissive. That mix decides the measured building survey route in Ealing more than the postcode does, and it is what a Ealing Council case officer reads first. A householder application costs £548 paid to Ealing Council direct, with 8 weeks to a decision once validated.
