Jobs
What can you get quoted for in Oxford?
Oxford quotes cover replacement windows, timber sash windows, secondary glazing, new sealed units and repairs, whether the house is a grade II terrace or a modern semi.
- Casement and tilt-and-turn windows in uPVC, timber or aluminium for post-war and modern homes
- Timber sash windows that copy the existing glazing bars, or sash-look uPVC where the council allows it
- Secondary glazing, an inner window that keeps the original in place
- Glass-only replacement of misted sealed units in sound frames
- Repairs to hinges, handles, locks and seals
Doors are a separate trade for some firms, so ask the installer whether they fit front, back or patio doors.

Local factors
What changes an Oxford double glazing quote
An Oxford quote turns on five things: a listing, a conservation area, the Osney Town Article 4, a let and a flat. Settle each before the survey, so every quote prices the same windows.
| In Oxford | What it changes in your quote | Ask or check |
|---|---|---|
| 1,181 listed building entriesHistoric England list | Almost any window change needs listed building consent | Who prepares and submits the consent drawings |
| 18 conservation areasOxford City Council | Front windows may need planning permission | Your street on the council's conservation area pages |

Listed buildings
Replacing windows in a listed Oxford home
A listed Oxford home needs listed building consent for almost any window change. The Historic England list holds 1,181 entries in Oxford: 195 grade I, 80 grade II* and 906 grade II. That is about 18.5 entries per 1,000 homes, against 14.6 across England.
Oxford's 195 grade I entries are the most of any city we cover outside London. On a listed building, like-for-like timber or secondary glazing is often the only acceptable option, so the field narrows to joiners and installers who make timber windows and prepare consent drawings.
- Find your entry on the Historic England list before the first survey.
- Ask each installer for addresses and photos of listed jobs in Oxford, and who submits the drawings to Oxford City Council.

Conservation areas
Window quotes in Oxford's 18 conservation areas and Osney Town
Oxford City Council states that "Oxford has 18 Conservation Areas at present", including the Central (City and University), Headington Hill and Wolvercote and Godstow areas.
Osney Town carries an Article 4 direction, which removes some permitted development rights so that changes normally made without an application need planning permission. The council publishes an "Article 4 Windows and Doors Guidance" and a "Window Components Guidance" note for Osney Town.
- Give installers the Osney Town guidance if your home is there, and ask them to quote to it.
- Ask whether they will draw the windows for a planning application if one is needed.

Window types
Double glazing or secondary glazing for an Oxford period home?
Secondary glazing suits an Oxford home whose original windows must stay; double glazing suits one where the frames have failed and replacement is allowed. Get both priced for the same rooms before you decide.
| Question | Secondary glazing | Replacement double glazing |
|---|---|---|
| Original window | Kept, with a new inner pane | Removed and replaced |
| Listed building | Ask the council whether consent is needed | Listed building consent needed |
| Conservation area or Article 4 | Inside the room, so the street view is unchanged | Front windows may need planning permission |
| Building Regulations | Ask the installer how it is signed off | FENSA or CERTASS certificate, or building control |
| Best when | Frames are sound and the look must stay | Frames are rotten, warped or beyond repair |
For a timber sash renewal, ask for a quote that copies the existing bars, horns and opening method. Our page on sash window replacement lists what to ask.

Landlords and flats
Window quotes for Oxford landlords and flat owners
Oxford landlords need window quotes that state the energy rating, because 32.2% of Oxford households rent privately, against 20.3% across England and Wales (Census 2021). Private landlords must already meet a minimum EPC band E to let, and the government aims for as many rented homes as possible to reach band C or equivalent by 2030.
- Ask for the U-value or Window Energy Rating of each window, so an EPC assessor can record the upgrade.
- Quote several properties at once if you let more than one.
Flats need a different first step. 30.7% of Oxford households live in flats, against 21.7% across England and Wales. A leaseholder usually needs the freeholder's written consent before new windows go in: see our guide to replacing windows in a leasehold flat.

Repair or replace
Repair or replace your Oxford windows?
Oxford windows with sound frames are repaired; windows with rotten or warped frames are replaced. A misted pane is a failed sealed unit, and a glazier swaps the unit without touching the frame. Worn hinges, handles and seals are repairs too.
Heritage status tips the balance towards repair, which keeps a listed or Osney Town window out of the consent process. For a modern Oxford home, ask each installer for a unit-only price next to a full replacement price, and for the Window Energy Rating of the new window.

Before you sign
How to check an Oxford double glazing installer
Check an Oxford installer in six steps: scheme registration, company history, the guarantee, where the firm is based, written quotes and the deposit.
- Find the company on FENSA's installer search or the CERTASS register yourself, not from a logo on its website.
- Look it up on Companies House for its status, age and earlier names.
- Ask whether the guarantee is insurance-backed and how many years it runs.
- Ask where the firm is based and who fits, since many Oxford listings come from across Oxfordshire and beyond.
- Get three written quotes for the same spec and compare them with our guide on how to compare double glazing quotes.
- Keep the deposit small and protected: our double glazing deposit guide explains how.
Ignore the "25% glazing rule" some directory guides quote for replacements. The Planning Portal states that Building Regulations "have applied to all replacement glazing" since April 2002, so every replacement window needs a competent person scheme certificate or building control approval, however few you change.
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. Our double glazing cooling-off period guide has the detail.

FAQ
Oxford double glazing questions
Who will contact me after I ask for quotes?
A short phone call confirms the job first. Local installers who cover your OX postcode then contact you to arrange a survey and a written quote.
Can I have double glazing in a listed building in Oxford?
Double glazing in a listed Oxford building needs listed building consent from Oxford City Council, and secondary glazing behind the original windows is the common alternative.
Do I need planning permission for new windows in an Oxford conservation area?
Planning permission is needed in Osney Town for window changes the Article 4 direction covers; elsewhere, check your street with Oxford City Council before you order.
Which double glazing company in the UK is considered the best?
No company is best for every home: the right one for an Oxford home is FENSA or CERTASS registered, has done listed or period jobs like yours and quotes the same spec as the others you compare.
Is it worth replacing 20 year old double glazing?
Replacing 20-year-old double glazing is worth it when the frames are rotten, warped or no longer close tight; misted units, worn seals and stiff hinges in sound frames are repairs. Ask for both prices on one visit.
What is the best time of year to buy double glazing?
No month is proven cheapest, and in Oxford the consent timetable matters more than the season; see our guide to the best time to buy double glazing.
What are the disadvantages of double glazing?
The main disadvantages of double glazing are the up-front cost, sealed units that mist when their seal fails, and the loss of original windows on a period home. In Oxford, a listed home needs consent for almost any window change, so secondary glazing is often the simpler route.
How much should I expect to pay for double glazing?
The price depends on the window count, style and consent work on your written quotes, and our sister site sets out what double glazing costs in each UK region.
