South Birmingham's housing stock keeps window fitters busy. Kings Heath, Moseley and Bournville are full of Edwardian and 1930s semis with original timber sashes and bay windows, while Selly Oak, Stirchley and Cotteridge have rows of Victorian terraces where conservation-minded owners often want timber or heritage-style uPVC. Further out, Northfield, Longbridge, Rubery and Weoley Castle are packed with 1950s and 60s estates where tired single-glazed or early uPVC units are being swapped for modern double glazing. Moseley and Bournville both have conservation areas, so planning rules can affect what you're allowed to fit. Check before you order.

The businesses on this page were drawn from third-party business listings and ranked by public review rating and review count, with a small lift for those showing a working website and phone number. We read each business's homepage to confirm window installers work is what they primarily offer, which keeps unrelated trades off the page. Listings flagged as permanently closed are removed automatically. Where you see a Trust Verified badge, that business has additionally passed our full verification covering trade qualifications and accreditations, public liability insurance, trading history, customer review history, and registered company information. Our How We Verify page sets out the full list. Businesses without the badge haven't been independently verified by us, so the checks below are ones you should make yourself before booking.

Ask every installer for a written, itemised quote that names the glass specification, frame material, colour, handle and hinge details, and what happens to your old units. Ask whether they're registered with FENSA or CERTASS, because that's how replacement windows are signed off under Building Regulations, and you'll want the certificate for your records and for any future house sale. Get a copy of their public liability insurance and ask about the guarantee, including whether it's insurance-backed in case the company stops trading. Never pay a large deposit up front. Get at least two or three quotes, and compare like for like, as a cheap price often hides thinner glazing or basic fittings.

Frequently Asked Questions

How much does a window installer cost in South Birmingham?
For standard white uPVC double glazing, expect roughly £350 to £700 per window fitted, depending on size and style. A typical three-bed semi in Kings Heath or Northfield, with around eight to ten windows, often lands between £3,500 and £7,000. Bay windows cost more, usually £1,200 to £2,500 each. Coloured or woodgrain finishes add 20 to 30 per cent, and aluminium or timber sashes can double the price. Triple glazing, bigger openings and difficult access push costs up too. Getting two or three quotes is normal, and you should compare the glass spec and fittings, not just the total.
Do I need FENSA or CERTASS paperwork for new windows?
Yes. Replacing windows counts as notifiable work under Building Regulations, and an installer registered with FENSA or CERTASS can self-certify it. You'll get a certificate, which solicitors will ask for when you sell. If your installer isn't registered, you'd need to apply to Birmingham City Council building control, which costs extra and can be a hassle. Ask for the certificate to be issued after completion, and keep it with your deeds.
Can I fit new windows in a conservation area like Moseley or Bournville?
Sometimes, but not always as you'd like. Both areas have conservation status, and some streets are covered by an Article 4 direction, which removes the usual right to change windows without planning permission. That often means like-for-like replacements in timber or a close visual match. Contact Birmingham City Council's planning team with your postcode before you order, as fitting the wrong style can mean being told to reverse it.
How long does a window replacement take?
Most installers fit a whole house in one to two days. A standard window takes about an hour or two, and a bay window half a day. Lead times for manufacture are the slower part, usually three to six weeks for uPVC and longer for bespoke timber or aluminium. Expect some dust and a bit of making good around the reveals, so ask whether plastering or decorating is included or whether you'll need to arrange that separately.
What's the difference between A-rated and B-rated windows, and is it worth paying more?
The energy rating reflects how well the whole window keeps heat in. A-rated units are the common standard now and often sit in the same price band as lower grades, so there's little reason to accept less. The bigger gains come from the spacer bars, the gas fill between panes, and a good fit with no draughts. If you're replacing old single glazing in a 1930s semi, you'll notice the difference immediately in your gas bill and in less condensation. Triple glazing is worth considering mainly on noisy roads like the A38 or Pershore Road.
How do I choose between window installers and check they're reliable?
Start with the paperwork. Ask for proof of FENSA or CERTASS registration and check it on the scheme's own website, then request a copy of their public liability insurance. Read online reviews for patterns, such as how they handled snagging, rather than just the star rating. Ask for a written quote with the glass spec, fitting details and a clear payment schedule, and avoid anyone demanding a big deposit or pressuring you to sign on the day. Check the guarantee is insurance-backed, and ask to see recent local jobs. Remember that businesses without our Trust Verified badge haven't been independently checked by us, so these steps are yours to do.
