Bays, frames and glass
What you can get quoted for in Birmingham
Birmingham installers quote for whole bays, sealed units, repairs and acoustic glass. The typical job is an inter-war semi with a two-storey bay: 27.0% of Birmingham properties were built between 1919 and 1939 (VOA, Council Tax stock of properties 2025), and semi-detached is the most common house type at 35.6% of households (Census 2021, TS044).
- Whole bay windows, priced as their own line, with any leaded or Art Deco top lights copied. A brand new bay counts as an extension under planning rules (Planning Portal).
- Timber or heritage-profile windows for the 11 Article 4 areas and the 19.6% of homes built before 1919. See sash window replacement if yours are box sashes.
- Replacement sealed units and repairs where the frame is sound and only the glass, a hinge or a lock has failed.
- Acoustic glass near Birmingham Airport, where noise matters more than the energy rating.
Doors: ask the installer whether they quote for them at the same visit. In the Article 4 areas, check door changes with the council too.

Planning first
Where do new windows need planning permission in Birmingham?
New windows need planning permission in the 11 Birmingham conservation areas covered by Article 4 directions. Birmingham City Council says that in these areas "even minor residential alterations, for example constructing a porch replacing windows or re-roofing, will require planning permission". The 11 areas are:
- Austin Village
- Bournville Village
- Edgbaston (part)
- Greenfield Road
- High Street, Sutton Coldfield
- Moor Pool, Harborne
- Moseley
- Old Yardley
- Selly Park
- Selly Park Avenues
- St Agnes
A standard uPVC swap in these streets can be refused, and fitting without consent risks enforcement action. Moor Pool has its own council page on replacement windows and a set of council window drawings.
What to ask an installer working in an Article 4 area
- Ask who prepares and submits the planning application, and whether the quote includes it.
- Ask whether they supply timber or heritage-profile windows that match the area guidance.
- Ask whether they have completed Article 4 jobs in Birmingham before.
- Ask how long the quote stays valid while you wait for a decision.
Other conservation areas and listed homes
Birmingham has 29 conservation areas in total (council page updated 2 June 2026), so 18 have no Article 4 window control. Windows there are usually permitted development when they look "similar" to the originals (Planning Portal), but the appearance of front windows still matters. Leicester also brings window changes under Article 4 control in parts of the city, as our page on double glazing in Leicester explains.
Birmingham also has 1,520 listed building entries on the Historic England list (24 grade I, 110 grade II*, 1,386 grade II). A listed home needs listed building consent before any window change, whatever area it is in.

Rentals and flats
Window quotes for Birmingham landlords and flat owners
Birmingham homes rate below the England average: 47.19% of Birmingham homes with an EPC reach band C or above, against 53.28% for England. Semis manage only 28.71%, and pre-1929 homes 16.47% (ONS, tables 2a to 2c, to financial year ending 2025).
Private landlords in England must reach EPC band C on all tenancies by 1 October 2030, and "double glazing for windows" is a named fabric measure (DESNZ, January 2026). 22.6% of Birmingham households rent privately (Census 2021, TS054). Ask for the Window Energy Rating or U-value of every window in writing for the EPC assessor.
24.5% of Birmingham households live in flats. The Planning Portal says that "if you are a leaseholder, you may first need to get permission from your landlord or management company", so get that consent in writing first. Our guide to replacing windows in a leasehold flat sets out the steps.

Aircraft noise
Acoustic glass quotes near Birmingham Airport
Birmingham Airport says its current sound insulation scheme of works is finished and every eligible property inside the scheme boundary has been insulated. Homes bought near the airport can already have scheme-fitted acoustic units, so ask the airport before you replace them. Otherwise ask installers to quote acoustic laminated glass with its sound reduction (Rw) figure.

Repair or replace
Misted or broken windows in Birmingham: repair or replace?
A misted or broken pane in a sound Birmingham frame needs a new sealed unit or a repair, not a new window. A rotten, warped or single-glazed window needs replacing. On a 1930s bay, a new unit leaves the bay frame in place, while a new bay replaces the whole projection.
- Repair or reglaze when mist sits between the panes of a frame that closes tight, a hinge or lock has failed, or one leaded top light is cracked.
- Replace when the frame is rotten or lets in water, the window is still single glazed, or several units in the same bay have failed.
A full replacement window is a "controlled fitting" under the Building Regulations: a FENSA or CERTASS installer self-certifies it and you get a certificate, or building control approves it (Planning Portal).

Before anyone measures up
How to check a Birmingham double glazing installer
Check a Birmingham installer in five steps, using public registers and paperwork rather than the firm's own claims. We do not vet or rank installers, so these checks are yours to run. Our page on checking double glazing installers explains each register and document.
- Registration: find the firm on the FENSA installer search or the CERTASS register. No registration means the job needs building control approval instead.
- Company record: search the name on the quote at Companies House for its start date, directors and any past liquidation.
- Guarantee: ask whether it is insurance-backed and which insurer stands behind it. A company-only guarantee ends with the company. Our guide covers what to do when a double glazing company goes into administration.
- Article 4 experience: in Moseley, Bournville or the other Article 4 areas, ask for a Birmingham job where the firm handled the planning application.
- Three like-for-like quotes: same windows, frame material and glass rating, with each bay on its own line. Our guide on how to compare double glazing quotes shows what to line up.

FAQ
Double glazing quotes in Birmingham, answered
Who will contact me after I ask for quotes?
A short call confirms the job first. Local installers who cover your postcode then contact you to book a survey and give a written quote.
Am I entitled to free double glazing?
No one is automatically entitled to free double glazing. Glazing is an eligible measure under the Warm Homes: Local Grant, which Birmingham City Council runs from 2025 to 2028, so check whether your household qualifies on the council's Warm Homes: Local Grant page before you pay yourself.
Do I need planning permission for windows in Birmingham?
Windows need planning permission in Birmingham's 11 Article 4 conservation areas, including Moseley, Bournville Village and Moor Pool, and on listed buildings and flats. Elsewhere, replacement windows of similar appearance are usually permitted development.
Is it worth replacing 20 year old double glazing?
Replacing 20 year old double glazing is worth it when the frames or several units have failed. Standards are stricter now: a replacement window in England must reach a U-value of 1.4 W/(m²·K) or Window Energy Rating band B (Approved Document L, 2021 edition, Table 4.2). The Energy Saving Trust puts the life of well-fitted double glazing at 20 to 35 years.
What is the best time of year to buy double glazing?
No season is proven cheapest: Which? says installers are quietest in winter and may offer discounts, but publishes no data. In an Article 4 area, ask for quotes once you know what you are allowed to fit. Our guide on the best time of year to buy double glazing covers timing in detail.
What are the disadvantages of double glazing?
Double glazing's main disadvantages are sealed units that mist with age, airtight rooms that need trickle vents kept open, and limits on what listed homes and conservation areas can fit (Energy Saving Trust). In Birmingham's 11 Article 4 areas, a standard uPVC swap can be refused.
How much should I expect to pay for double glazing?
This site covers getting and comparing quotes. For prices, see what double glazing costs in Birmingham on our sister site.
How much does double glazing cost in Birmingham?
A Birmingham price depends on the number of windows, the frame material and glass rating, whether a bay is replaced whole, and whether an Article 4 area needs timber. Three written quotes for the same specification show what your home will cost.
