Conservation areas
There is no "Hanwell Broadway" or "Hanwell Flight of Locks" conservation area - the canal is covered by St Mark's Church and Canal, and Boston Manor is in Hounslow. See Ealing's conservation area pages.
Housing stock in Hanwell
Hanwell's conservation areas run from the Village Green and Churchfields through the interwar Cuckoo Estate to the canal at St Mark's. Ealing's own guidance notes its conservation areas typically contain original timber sash and casement windows and steel-framed windows.

Frequently asked about Hanwell
Is there an Article 4 direction in Hanwell?
Yes, but not on windows. Ealing's Churchfields - Half Acre Road direction, made in 1996, covers roof additions and alterations only. The four Ealing directions that name window and door replacement are all elsewhere in the borough: Brentham, The Grove, Hanger Hill Garden Estate and Haymills.
Which conservation areas cover Hanwell?
Churchfields, Hanwell Village Green, Cuckoo Estate, Hanwell Clock Tower, St Mark's Church and Canal, and Hanwell Cemeteries. There is no "Hanwell Broadway" designation, and the canal locks are covered by the St Mark's Church and Canal area.
So can I fit what I like in a Hanwell conservation area?
Not quite. Permitted development still requires materials of similar appearance to the original construction, and Ealing states that plastic looking windows are not likely to be acceptable replacements for timber or steel-framed windows. But without an Article 4 on windows, a genuine like-for-like replacement on an unlisted house does not need permission.
What if I own a flat in Hanwell?
Flats and houses converted to flats have no permitted development rights in Ealing, so planning permission is always needed to change doors and windows.
What is the safest way to upgrade thermally?
Ealing points to double or triple glazing inserted into timber frames as the route that keeps a consistent appearance and is unlikely to require permission. Where you are unsure, the council recommends a Lawful Development Certificate.
Hanwell: where the restriction actually falls
Hanwell is in the London Borough of Ealing, which counts around 30 conservation areas. Six of them cover W7, but the Article 4 direction here - Churchfields, Half Acre Road, made in 1996 - is restricted to roof additions and alterations. It does not remove permitted development rights for windows.
That is a meaningful difference from Brentham or Hanger Hill, where the directions itemise "replacement of windows and doors" as one of the works requiring permission.
What still applies everywhere is the permitted development test itself: materials must be of similar appearance to those used in the original construction, and the design should be similar in glazing pattern and style. Ealing's adopted Policy 7C in the 2013 Development Management DPD then governs anything that does need an application.
