What you can get quoted for in Ilford
Ilford installers quote for new windows, glass-only units, secondary glazing and repairs from one enquiry:
- Replacement windows in uPVC, aluminium or timber for bays, flat fronts and backs;
- Timber slimline or sash windows for Aldersbrook and Edwardian streets, compared under sash window replacement;
- Sealed-unit replacement for misted glass;

Grants
Ilford double glazing grants: check before you get quotes
A grant can pay for double glazing in Ilford when the home is rated EPC D or below and the household income is 36,000 pounds or less. Redbridge Council's home improvement grants page lists "double glazing" among the Warmer Homes: Local Grant measures, funded by DESNZ and delivered by the Greater London Authority.
- Who can apply: owner-occupiers, private landlords and tenants.
- How measures are chosen: a surveyor recommends them after a full retrofit survey, so windows are funded only where it includes them.
- Other measures on the list: wall, loft and underfloor insulation, air source heat pumps, solar panels and heating controls.
Only 46.3% of EPC-rated Redbridge homes reach band C or above, against 57.9% across London, and only 24.0% of homes built before 1929 do (ONS, to March 2025).
- Find your rating on the GOV.UK EPC register.
- If it is D or below and your income fits, apply through the GLA's Warmer Homes page before booking any window survey.
- If you do not qualify, ask installers for the whole-window U-value on every quote, so the next EPC can record the gain.
The grant is applied for through the GLA, not sold at the door. Anyone charging you to "unlock" it is not part of the scheme.

Replacement windows for Ilford's 1930s semis and Edwardian streets
Ilford quotes split between inter-war bays and Edwardian fronts. 34.3% of Redbridge properties were built from 1919 to 1939 and 26.8% before 1919, while 27.0% of households live in a semi, against 18.6% across London (VOA 2025; Census 2021).
- 1930s semis in Gants Hill, Newbury Park and Clayhall: ask for the bay as its own line, whether any structural support is included, and how leaded or coloured top lights will be matched.
- Edwardian terraces in Ilford, Seven Kings and Aldersbrook: ask for a sash or timber casement option alongside standard uPVC.
- Flats: 33.6% of households live in one. Flats have no permitted development rights for windows, so get the freeholder's consent first, using our guide to replacing windows in a leasehold flat.
The Planning Portal says a new bay "will be treated as an extension and may require permission". Keep a bay to its existing shape unless you plan to apply.

Planning
Do you need permission for new windows in Redbridge?
New windows need planning permission on houses covered by a Redbridge Article 4 direction, and on listed buildings and flats. Other Redbridge houses usually need none for a similar-looking replacement. The council has 16 conservation areas.
| Direction | Which windows | What to ask installers |
|---|---|---|
| Aldersbrook and Lake House (2020) | Front, side and rear windows of every house and garage | Timber slimline double glazing or secondary glazing, and the application |
| The Drive, Snaresbrook | Windows and frames on the front elevation | A front design matching the original |
| 1 to 47 Spratt Hall Road (2013) | Windows fronting the highway | Front and rear priced as separate lines |
| 32 to 38 Cumberland Close (1996) | Alterations to the house, which include windows | Whether the quote includes drawings |
Aldersbrook is the strictest: even rear windows need permission. Its design guide asks for replacements that are "timber, slimline and close in shape and style to Edwardian window designs". It also says that where timber frames survive, "secondary glazing, shutters and alternative draught-proofing measures are strongly encouraged".

Before you sign
How to check an Ilford double glazing company
Check an Ilford company on its scheme register, on Companies House and against a written guarantee, and never buy at the door. Redbridge runs Doorstep Calling Restricted Zones, signed on lamp posts, that tell traders "residents do not buy goods and services at the door". The council warns that rogue traders "will often try to convince you that work needs to be carried out on your home".
- Search the company on fensa.org.uk or certass.co.uk. A registered installer self-certifies the work under Building Regulations.
- Look it up on Companies House: active status, age and previous names.
- Ask for an insurance-backed guarantee in writing, with its length.
- Confirm the firm works in your IG or E postcode: directories often list Ilford under Essex and mix in firms from Chelmsford or Sidcup.
- Compare itemised quotes using our guide on how to compare double glazing quotes.
Adverts showing Martin Lewis selling windows are fake: MoneySavingExpert says he "doesn't do ads". If you sign at home, you usually have at least 14 days to cancel, but made-to-measure windows can be an exception, so check the contract before you sign. The double glazing cooling off period guide has the detail, and how to choose a double glazing installer has the full checklist.

FAQ
Double glazing in Ilford: questions answered
Can I get a grant for double glazing in Redbridge?
Redbridge homes rated EPC D or below, with household income of 36,000 pounds or less, can get double glazing funded under the Warmer Homes: Local Grant when the retrofit survey recommends it.
What are people saying about Martin Lewis at Help to Buy windows?
Help to Buy windows adverts using Martin Lewis are scams: MoneySavingExpert states he does not do adverts or endorse products. Redbridge's real window funding is the Warmer Homes: Local Grant, applied for through the GLA.
Is Ilford in London or Essex?
Ilford is in London, in the London Borough of Redbridge, though its postal county is still Essex. Redbridge Council handles planning, grants and Trading Standards for Ilford.
What is the best time of year to buy double glazing?
The best time to buy double glazing in Ilford is after you have checked the Warmer Homes grant, because funded windows cost you nothing. No month is proven cheapest, as our guide to the best time of year to buy double glazing explains.
Is it worth replacing 20 year old double glazing?
Replacing 20 year old double glazing is worth it when the frame has failed; a misted pane in a sound Ilford frame needs only a new sealed unit.
What are the disadvantages of double glazing?
Double glazing's main disadvantages are sealed units that mist when seals fail, thick uPVC glazing bars that Redbridge's Aldersbrook guide calls out of character on Edwardian houses, and permission needed on Article 4 streets.
How much should I expect to pay for double glazing?
Your price rests on window count, bays, frame material and any Article 4 work, so compare itemised quotes and see what double glazing costs in London on our sister site.
