Planning
Do you need planning permission for new windows in Ealing?
You need planning permission for new windows on four Ealing estates where an Article 4 direction names them, and in any flat in a conservation area. The council notes that "Affected development varies from area to area".
| Area | What the direction controls |
|---|---|
| Brentham Garden Estate | Alterations to a house, including "replacement of windows and doors", porches, roof materials and chimneys |
| Hanger Hill Garden Estate | Alterations to a house, including "replacement of windows and doors" and front porches |
| Hanger Hill (Haymills) Estate | "Alterations to the front elevations of properties, including replacement of windows" |
| Ealing Town Centre: The Grove | "replacement of windows and doors" and "alterations to stonework, brickwork and external timbers" |
| Bedford Park (Ealing side) | Enlargement, improvement or alteration of a house; the council's summary does not name windows |
On the Bedford Park side of the borough, ask the council how its direction treats windows before ordering. The Chiswick side of Bedford Park has its own schedule, set out on our page for double glazing quotes in Hounslow. For houses with no direction, the planning permission for windows checker covers the general rules.

Conservation areas
Is double glazing like for like in an Ealing conservation area?
Double glazing is not always like for like in Ealing's conservation areas, because sealed units are deeper than single glass. Ealing published a draft management plan for conservation areas for consultation in February 2022. It says double glazing units "may not be considered as like for like in some cases as they are usually deeper in profile than original single glazed units".
- Slim units: "timber or aluminium 'slimlite', or similar units with reduced depths may help overcome this issue".
- Materials: "PVC-U and aluminium replacements are not generally acceptable", while "slim section" replacements are considered on rear facades hidden from view, on isolated or detached buildings, or where they would not harm the area.
- Listed buildings: "In listed buildings, double glazed windows will not normally be approved."
Ask each installer for the unit depth and a drawing of the frame profile with the quote, so you can compare them against the original window.

Flats
Window quotes for Ealing flats and converted houses
An Ealing flat in a conservation area needs planning permission for replacement windows, and every flat needs the freeholder's consent. The draft management plan states that "planning permission is always required for replacement windows in flats in CAs". For blocks, "agreement should be reached where possible with all other residents so that all the windows in the building are the same".
49.5% of Ealing households live in a flat, maisonette or converted building: 34.5% in purpose-built blocks and 12.7% in converted or shared houses (Census 2021).
- Check the lease for who owns the frames.
- Agree one window design with the freeholder and the other flats.
- Ask each installer whether the quote covers the planning application.

Landlords
Window quotes for Ealing's rented homes
Ealing landlords need window ratings in writing. 34.0% of the borough's households rent privately, above the London figure of 30.0% (Census 2021), and private lets must reach EPC band C or register an exemption by 1 October 2030 (DESNZ, January 2026). Ask installers for the U-value or Window Energy Rating of every window, and keep it for the EPC assessor.
Period windows
Sash and period window quotes in Ealing
A period Ealing window is quoted to keep its opening style: the draft management plan says "sliding sash windows should not be replaced with top hung windows or casements". 28.2% of the borough's properties were built before 1919 and 30.1% between 1919 and 1939 (VOA 2025), and 31.2% of homes built before 1929 reach EPC band C (ONS).
- Secondary glazing: "acceptable in principle", with fixings that can be reversed.
- Glazing bars: copied "on the outside rather than just between the panes of glass".
- Openings: top-hung, bottom-hung and pivot windows are "unsuitable for use in CAs" unless original.

Repair or replace?
Repair or replace windows in Ealing?
Repair comes first for Ealing's conservation area windows: the draft plan calls "the repair of existing windows in traditional materials" the "preferred option", together with secondary glazing. Replace when the frame has failed or the house sits outside the controls.
| Your window | Route | Ask the installer |
|---|---|---|
| Original timber sash in a conservation area | Repair and secondary glazing | A repair price beside a replacement price |
| Misted unit, sound frame | New sealed unit | The guarantee on the unit |
| Flat in a block | Replacement to the block's agreed design | The specification the freeholder approved |
| Failed frame, no controls | Full replacement | The whole-window U-value in writing |

How to check an Ealing double glazing company

- Search the firm on the FENSA or CERTASS register.
- Check the company on the quote is active on Companies House.
- For Brentham, Hanger Hill or The Grove, ask for a past planning reference on one of those estates.
- Get the insurance-backed guarantee in writing.

FAQ
Double glazing in Ealing: questions answered
Do I need planning permission to replace windows in a flat in Ealing?
An Ealing flat in a conservation area needs planning permission for replacement windows, according to the council's draft management plan, and any flat needs the freeholder's consent first.
Can I fit uPVC windows on the Brentham or Hanger Hill estates?
Brentham and Hanger Hill Garden Estate need planning permission for any replacement windows, and Ealing's draft guidance says "PVC-U and aluminium replacements are not generally acceptable" in conservation areas.
Which is the best double glazing company in the UK?
The right company for an Ealing home is registered with FENSA or CERTASS, active on Companies House, gives an insurance-backed guarantee in writing and can show past conservation area work in the borough.
What is the best time of year to buy double glazing?
The best time in Ealing is after planning permission or freeholder consent is in hand, because a fitting date before approval cannot be kept. Our guide to the best time of year to buy double glazing covers seasons and lead times.
Is it worth replacing 20 year old double glazing?
Replacing 20 year old double glazing in Ealing is worth it when the frame has failed; a misted unit in a sound frame needs only a new sealed unit.
How much should I pay for double glazing?
The price depends on the window count, timber or uPVC, and any consent work, so compare itemised quotes and read what secondary glazing costs on our sister site if you are keeping original windows.
