What changes a Romford double glazing quote
Five things change a Romford quote: house shape, energy rating, renting, Gidea Park's Article 4 and grant callers. Check them before the survey, so each installer quotes for the same windows.

Who sets the rules
Is Romford in London or Essex? Who sets the rules for your windows
Romford is in the London Borough of Havering, part of Greater London since 1965. Havering Council handles planning, building control and Trading Standards for Romford, Hornchurch, Upminster, Harold Wood and Rainham, even though addresses still read "Romford, Essex".
Essex County Council guidance and Essex district Article 4 lists do not apply to an RM postcode. Havering's own heritage page, Article 4 list and energy advice page do.
Romford Road is a different place. It runs through Forest Gate and Manor Park (E7 and E12) in the London Borough of Newham, so a firm on Romford Road is not necessarily near Romford. Ask any installer which RM districts it covers before booking a survey.

Replacement windows for Romford's 1930s bays and post-war houses
Havering's housing is 70.8% inter-war or post-war: 35.6% of properties were built from 1919 to 1939 and 35.2% from 1945 to 1972. Only 4.9% pre-date 1919, against 29.1% across London.
| Measure | Havering | London |
|---|---|---|
| Properties built 1919 to 1939 | 35.6% | 22.2% |
| Properties built 1945 to 1972 | 35.2% | 16.9% |
| Households in a semi-detached house | 41.2% | 18.6% |
| Households in a house of any type | 76.7% | 45.9% |
| Households that own their home | 69.5% | 45.2% |
A Romford quote is usually for a whole semi: a front bay, flat windows to the side and back, and often a porch. Enfield's inter-war semis raise the same bay questions, set out under double glazing quotes in Enfield.
- Bay on its own line: the Planning Portal says a new bay "will be treated as an extension and may require permission", so confirm the quote replaces the bay like for like.
- Top lights: ask whether leaded or coloured top lights on a 1930s bay will be copied or replaced with plain glass.
- Post-war openings: ask the surveyor to measure every opening rather than estimate from one window.

Energy ratings
Energy-rated window quotes for Romford's low-EPC homes
Only 43.8% of Havering homes with an EPC reach band C or above, the lowest share of any London borough, against 57.9% for London and 53.3% for England. For homes built before 1929 the figure is 14.9% (ONS, to March 2025).
With 69.5% of households owning their home, most Romford window buyers pay the heating bill themselves. Ask each installer for the whole-window U-value or Window Energy Rating on the written quote, and compare that, not the glass figure alone.
Landlords renting out the 15.8% of privately let Havering homes face a 1 October 2030 deadline to reach EPC band C or register an exemption (DESNZ, January 2026). Keep each window's rating in writing for the next EPC.

Planning
Gidea Park window quotes: when you need permission
Window changes need planning permission on listed addresses in the Gidea Park conservation area, under an Article 4 direction confirmed on 24 June 2016. It is the only Havering direction that reaches windows. The others cover satellite dishes at Havering-atte-Bower and boundary walls at Cranham.
- Control Level 1: alterations "to the front and sides of the dwellinghouse".
- Control Level 2: alterations "to the front, sides and rear", plus porches and exterior painting.
- Streets: named house numbers on roads including Heath Drive, Reed Pond Walk, Meadway, Parkway, Brook Road and Balgores Lane.
The July 2025 Gidea Park appraisal records "unsympathetic replacement of traditional timber and metal windows ... with uPVC units". Havering's Heritage SPD adds that where permission is needed, "only matching materials are likely to be acceptable". Ask installers in Gidea Park for timber or steel replacements, and whether they will prepare the application.
Emerson Park in Hornchurch is a policy area, not a conservation area, and has no window control.

Grant scams
Free double glazing in Romford? What Havering says about grant callers
Havering does not offer free double glazing, and it warns about people charging fees for grants. Its energy advice page says: "We have become aware of individuals operating in London who are approaching residents and asking for a fee" in connection with Warm Homes: Local Grant.
The council lists insulation, heat pumps, solar panels, ventilation and damp prevention as the grant's measures, with no windows, and says the scheme "is not delivered by Havering Council directly". Never pay anyone to access a grant. Report the caller to Havering Council Trading Standards, as the council asks.

Repair or replace?
Repair or replace windows in a Romford house?
Repair a Romford window when the frame still seals and replace it when the frame has failed. Ask for a repair price and a replacement price on the same visit, so you see both before choosing. Our page on window replacement across London sets out each step from survey to certificate.
- Condensation between the panes: the sealed unit has failed. Ask for a unit price before a window price.
- Draughts or a sash that drops: ask for new seals and hinge adjustment.
- Frames that bow, crack or let water in: ask for replacement, with the U-value written down.
- Original timber or metal windows on a Gidea Park house: ask for repair first, because the appraisal "strongly" discourages replacing historic windows "unless they are damaged beyond repair".

Before you sign
How to check a Romford double glazing company
Check a Romford company on the FENSA or CERTASS register and on Companies House, then get three written quotes. Havering's Trading Standards pages cover doorstep-sale cancellation rights and the Buy With Confidence scheme.
- Search the company name or postcode on fensa.org.uk or certass.co.uk. Registration lets the installer self-certify the job under Building Regulations.
- Check Companies House for an active company, its age and any earlier names.
- Read reviews on platforms the installer does not control, and compare the count as well as the score.
- Ask for an insurance-backed guarantee in writing, so it holds if the company stops trading.
- Compare itemised quotes with our guide on how to compare double glazing quotes.
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. See the double glazing cooling off period guide, and how to choose a double glazing installer for the full checklist.

FAQ
Double glazing in Romford, answered
Do I need planning permission for new windows in Romford?
Most Romford houses need no planning permission for similar-looking windows. Listed Gidea Park addresses on the Article 4 list, listed buildings, flats and new bays need permission or consent.
Which double glazing company is considered the best in the UK?
No double glazing company holds an official "best in the UK" title, and we do not rank installers. Judge a Romford firm on its FENSA or CERTASS registration, its guarantee and a written quote for the same windows as its rivals.
Is Romford in Essex or London?
Romford is in London, in the London Borough of Havering, and has been since 1965. Its postal county is still Essex, which is why many installers list it under Essex.
Is it worth replacing 20 year old double glazing?
Twenty year old double glazing in a Romford house is worth replacing when the frames bow, leak or will not lock; misted glass alone needs a new sealed unit.
What are the disadvantages of double glazing?
The disadvantages of double glazing are sealed units that can mist years later, uPVC that Havering's heritage guidance discourages on listed and Gidea Park homes, and a larger spend than repairing frames that still work.
How much should I expect to pay for double glazing?
Expect the total to track window count, bays, frame material and glass, so compare itemised quotes and see what double glazing costs in London on our sister site.
