What you can get quoted for
What you can get quoted for in Enfield
Enfield installers quote for new windows, glass-only replacement, secondary glazing and repairs through one enquiry:
- Replacement windows in uPVC, timber or aluminium, with each bay on its own line;
- Timber casements or sashes for Article 4 frontages, compared in more depth under sash window replacement;
- Sealed-unit replacement where the frames are sound and only the glass has misted;
- Secondary glazing for protected fronts and homes on busy roads;
- Repairs to hinges, handles, locks and seals.
Ask the installer whether a front or back door can go on the same quote. On an Article 4 house a front door change can need permission too, because the 2006 wording names doors alongside windows.

Local factors
What changes an Enfield double glazing quote

Planning
Do you need planning permission to replace windows in Enfield?
Replacing front windows needs planning permission on houses named in Enfield's Article 4 schedules, which cover parts of 15 conservation areas. Elsewhere a house usually needs none for windows of similar appearance. Enfield Council lists 22 conservation areas in total.
| Direction | Areas covered | What it controls |
|---|---|---|
| 2006, Article 4(2) | Parts of Bush Hill Park, Clay Hill, Enfield Lock, Forty Hill, Hadley Wood, Southgate Green, Trent Park, Turkey Street, Vicars Moor Lane and Winchmore Hill | "Installation/ replacement windows" on elevations facing or visible from a highway or open space |
| 2008, confirmed 29 January 2009 | Most of Grange Park, Meadway and The Crescent | Alterations to a house that front a highway, open space or waterway |
| 2009, confirmed 30 November 2009 | Abbotshall Avenue, plus extensions to Clay Hill, Forty Hill, Enfield Lock and Southgate Green | Class A alterations, which include windows |
| 2017, in force 8 January 2018 | Enfield Town conservation area | Alterations to a house that front a highway, waterway or open space |
The schedules work address by address. A semi in Bush Hill Park can be on the list while the house next door is not. Rear windows that cannot be seen from a road or open space usually stay outside the 2006 control.
- Find your house number in the schedule for your conservation area on Enfield Council's Article 4 page.
- Ask every installer to quote a design that matches the original pattern, such as timber casements or a matching bay with top lights.
- Ask who prepares the drawings and submits the application, and whether that work is in the quote.

Replacement window quotes for Enfield's 1930s semis and bays
The typical Enfield window job is a bay-fronted inter-war semi or terrace.
| Measure | Enfield | London |
|---|---|---|
| Properties built 1919 to 1939 | 35.2% | 22.2% |
| Properties built before 1919 | 23.3% | 29.1% |
| Households in a semi-detached house | 24.8% | 18.6% |
| Households in a house of any type | 61.2% | 45.9% |
| Households that own their home | 52.4% | 45.2% |
Bays are where Enfield quotes differ most. The Planning Portal says a new bay window "will be treated as an extension and may require permission", so a like-for-like bay and a reshaped bay are two different jobs.
- Bay priced as its own line: a single total hides how much of the price the bay takes.
- Structural support stated: ask whether the installer checks the bay for movement and includes any support it needs.
- Top lights matched: ask how leaded or coloured top lights will be copied, kept or replaced.

Energy ratings
What Enfield's energy ratings mean for your quote
Only 45.7% of Enfield homes with an EPC reach band C or above, against 57.9% across London and 53.3% across England. For homes built before 1929 the share falls to 19.2% (ONS, to March 2025).
Most older Enfield houses are therefore rated D or below, and windows are one of the upgrades an assessor records. Ask each installer to state the whole-window U-value, not just the glass figure, so you compare the same measure on every quote.
Landlords have a deadline. 29.3% of Enfield households rent privately, and the government has set 1 October 2030 as the date for privately rented homes to reach EPC C or register an exemption (DESNZ, January 2026). Ask for each window's U-value or Window Energy Rating in writing, so the next EPC assessor can use it.

Repair or replace?
Repair, replace or secondary glaze your Enfield windows?
Repair or reglaze when only the glass or hardware has failed, replace when the frame has, and choose secondary glazing when the front must stay as it is. "Secondary glazing Enfield" and "double glazing repairs Enfield" are both common Google suggestions.
| Route | When it fits | What to ask |
|---|---|---|
| Sealed-unit replacement | Misted or blown panes in frames that still open, close and lock | The unit's spacer, gas fill and glass rating, and the guarantee on the new unit |
| Repair | Draughts, stiff hinges, broken handles or failed locks | Whether new seals and hinge adjustment fix it before any replacement |
| Secondary glazing | Original timber on an Article 4 frontage, or a noisy main road | Whether panels lift out or slide for cleaning, and how they fix to the reveal |
| Full replacement | Rotten timber, warped uPVC or frames that no longer seal | Frame material, whole-window U-value and a matching design on a listed frontage |
Secondary glazing sits inside the existing window, so the outside of the house stays as the schedule expects. Ask for a repair price and a replacement price on the same visit if you are unsure which route fits. Our page on London window replacement walks through the repair or replace decision in full.

Before you sign
How to check an Enfield double glazing installer
Check an Enfield installer on the FENSA or CERTASS register, on Companies House and against a written guarantee before anyone measures. Enfield Council's doorstep crime advice tells residents to display a "No Cold Calling" sticker and to "use accredited Trading Standards approved contractors". London Trading Standards warns that "there are more rogue traders offering insulation, double glazing, solar panels and heat pumps".
- Scheme register: search the company name or postcode on fensa.org.uk or certass.co.uk yourself. A registered installer self-certifies the job under Building Regulations and you receive a certificate.
- Companies House: confirm the company is active, how long it has traded and whether it has changed name.
- Guarantee: ask for an insurance-backed guarantee named in writing, with its length, so it survives if the firm stops trading.
- Written quotes: compare three itemised quotes for the same windows and glass, using 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. The double glazing cooling off period guide explains why. For the full checklist, read how to choose a double glazing installer.

FAQ
Enfield double glazing questions
Is there a government grant for double-glazed windows?
Enfield Council's Warm Homes: Local Grant page lists insulation, solar panels and air source heat pumps, not windows. Check the council page before trusting anyone who offers grant-funded windows in Enfield.
Do I need planning permission for new windows in Enfield?
A house on one of Enfield's Article 4 schedules needs planning permission to change front windows; other houses usually do not for a similar-looking replacement. Flats and listed buildings need permission or consent in every case.
What type of double glazing is best?
The best double glazing for an Enfield home is the type your street allows and your frame suits: matching timber on an Article 4 frontage, secondary glazing behind original windows you must keep, and uPVC or aluminium on houses with no control. Compare the whole-window U-value on each quote.
Is it worth replacing 20 year old double glazing?
Twenty year old double glazing is worth replacing only when the frames or hinges have failed. Misted panes, draughts and stiff handles usually need a new sealed unit, new seals or new hardware instead.
Is it worth replacing 30 year old double glazing?
Replacing 30 year old double glazing is worth it when the frames have warped, rotted or stopped sealing; when only the glass has misted, a new sealed unit in the old frame is the cheaper fix. Ask an Enfield installer to quote both routes on one visit.
What are the disadvantages of double glazing?
Double glazing has four main drawbacks: sealed units mist when their seals fail, uPVC frames rarely match period detail, Article 4 houses need permission for a new design, and replacing sound windows costs more than repairing them.
How much should I expect to pay for double glazing?
The price depends on window count, bays, frame material and any planning work, so compare itemised quotes and see what double glazing costs in London on our sister site.
