Double glazing quotes in Leicester
Compare free written quotes from local installers who cover your LE postcode, for replacement windows, sealed units, repairs and secondary glazing.

What installers quote for
What can you get quoted for in Leicester?
Leicester installers quote for replacement windows, new sealed units, repairs and secondary glazing, and one survey can price all four.
- Replacement windows in uPVC, aluminium or timber, casement or sash.
- Bay windows priced as one line for Victorian and Edwardian terraces.
- Sealed-unit replacement for misted or cracked glass in sound frames.
- Repairs to hinges, handles, locks and seals.
- Secondary glazing on the room side of windows that must stay, as on listed buildings.
Not every window firm fits doors, so ask the installer whether they quote for a front or back door too.

Quotes for Leicester's Victorian terraces: what to ask for
A Leicester terrace quote should price each bay as one line and offer a sash-style option, because so many of the city's homes are Victorian. The Valuation Office Agency counts 26.5% of Leicester properties as built before 1919 and 20.5% before 1900, against 20.0% and 15.0% across England (31 March 2026). The 2021 Census puts 29.2% of households in a terraced house, against 23.0% for England.
Homes of that age were built with timber sash or casement windows, often in a ground-floor bay. Many now have a first or second set of replacements, and the openings are rarely a standard size.
- Ask every installer to measure each opening at the survey, not from photos.
- Ask for a sash-style option in timber or uPVC next to a standard casement price.
- Ask whether the bay roof, posts and making good of the reveals are in the price.

Energy ratings
Window quotes that lift a Leicester home's EPC
New windows can lift a Leicester home further than an average English one, because only 42.8% of Leicester homes with an EPC reach band C, against 53.3% across England. For homes built before 1929 the share falls to 19.4% (ONS, tables 1a, 2a and 2c, to financial year ending 2025).
A replacement window in England must reach a U-value of 1.4 W/m²K or Window Energy Rating band B (Approved Document L, Table 4.2). Ask how far each quoted window beats that minimum.
Landlords: the 2030 EPC deadline
29.4% of Leicester households rent privately, against 20.5% across England (Census 2021, TS054). Private landlords must bring every tenancy up to the higher standard, equivalent to EPC band C, by 1 October 2030, and "double glazing for windows" is one of the named fabric measures (DESNZ, January 2026). Nearby Nottingham has a similar private rented share, 28.6%, set out on our Nottingham window quotes page.
- Ask for one quote per let, with the glazing specification the EPC assessor needs.
- Ask whether quotes for several properties can be surveyed in one visit.

Planning
Window quotes in Leicester's Article 4 and conservation areas
Leicester homes inside an Article 4 area can need planning permission for "changing windows or doors", a change that is normally permitted development (Leicester City Council). Article 4 directions apply to specific areas and buildings, so check your address on the council's Article 4 map before you order. In Birmingham, Article 4 directions control windows in 11 conservation areas, covered on our Birmingham double glazing quotes page.
Leicester has 25 conservation areas, including Stoneygate, Knighton, South Highfields, Ashleigh Road, New Walk, Evington Village, Old Humberstone and Aylestone village. The council also notes that "flats and commercial buildings do not have the same permitted development rights as single dwellings". The city has 395 entries on the Historic England list, and a listed home needs listed building consent for a window change.
- Ask installers whether they have fitted windows under a Leicester Article 4 direction.
- Ask who prepares the drawings if your street needs an application.
- Ask how long the quote stays valid while the council decides.

Repair or replace
Is it worth replacing 30 year old double glazing?
Replacing 30 year old double glazing is worth it when the frames have warped, the seals have perished or the locks no longer hold. Keep the frame when it is square, dry and secure, and replace only the misted units.
Use three questions to decide:
- Is the frame sound? A frame that is rotten, cracked or out of square needs a new window.
- Is only the glass misted? A failed sealed unit needs a new unit in the old frame.
- Must the original stay? On a listed building or a protected front, secondary glazing on the inside keeps the frame and adds a second pane.
Ask each installer for a repair or glass-only price and a whole-window price on the same quote, with the U-value of each option.

Comparing quotes
What changes the price on a Leicester quote?
Six things move a Leicester window quote, and two quotes only compare when they match on all six:
- Window count, with each bay counted as one line.
- Frame material: uPVC, aluminium or timber.
- Style: casement, sash or tilt and turn.
- Glass: WER or U-value, plus any acoustic or safety glass.
- Access for upper windows and the making good of old reveals.
- Drawings or applications for Article 4, conservation area or listed homes.

How to check a Leicester installer
Check a Leicester installer's registration, company record and guarantee before you let them survey, because a badge on a website proves nothing on its own. Our guide on how to choose double glazing installers walks through each register and record.
- Search the FENSA and CERTASS registers for the company name.
- Open the company on Companies House and check it is active.
- Get the guarantee terms in writing, and ask whether an insurer backs them. Our guide shows what happens if a double glazing company goes bust.
- Compare reviews on more than one site.
Bring our questions to ask a double glazing salesman to the survey. 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.

FAQ
Leicester double glazing questions
Who will contact me after I ask for quotes?
A short confirmation call comes first. Local installers who cover your postcode then contact you to arrange a survey and a written quote.
Is there a grant for double glazing in Leicester?
Leicester City Council says Warm Homes: Local Grant applications are currently closed because this year's funding is allocated, and may reopen in 2028, subject to funding. Its list of upgrades names insulation, heat pumps, heating controls and solar panels, not windows.
Do I need permission for new windows in a Leicester conservation area?
A house in a Leicester conservation area needs planning permission for new windows only when an Article 4 direction covers it, or when it is listed or a flat. Check the council's Article 4 map first.
Who is the best double glazing company in the UK?
There is no single best double glazing company in the UK. The right Leicester installer is on the FENSA or CERTASS register, offers an insurance-backed guarantee and quotes your exact windows in writing. Our guide on how to choose double glazing installers covers the checks.
Can I replace just the misted glass rather than the whole window?
Yes, a misted sealed unit is replaced on its own when the frame is sound, and it fits the existing frame. Ask for the unit's guarantee in writing.
Is it worth replacing 20 year old double glazing?
Replacing 20 year old double glazing pays off when the frames have failed or the home needs a better EPC band; a sound frame with misted glass needs new units only. In Leicester, where under half of homes reach band C, ask for the WER of each option.
What are the disadvantages of double glazing?
The disadvantages of double glazing are the up-front outlay, sealed units that eventually mist, less background ventilation without trickle vents, and a changed look on a Victorian front. In an Article 4 area, a changed look can also need planning permission.
How much should I expect to pay for double glazing?
The price follows the window count, frame, style, glass and access on your written quotes, and our sister site sets out what double glazing costs in each UK region.
