Swindon's housing stock gives window installers a mixed bag of work. Old Town and the Railway Village have Victorian and Edwardian terraces where original sashes and timber casements still turn up, and conservation rules can limit what you're allowed to fit. Further out, Abbey Meads, Haydon Wick, Park South and Westlea are full of 1970s to 2000s semis and estate homes, where tired uPVC units with failed seals (that misty look between the panes) are the most common reason people pick up the phone. Add the exposed, windy edges of the town towards the Downs and the Ridgeway, and thermal performance and draught-proofing matter more than people expect.
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 that window installation 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 has the full list. For anyone without the badge, we haven't independently checked those things, so you'll need to do it yourself before booking.
Start by asking every installer for a written, itemised quote showing the frame material, glass specification, fittings and whether removal and disposal of old units is included. Confirm they're registered with a relevant trade accreditation such as FENSA or CERTASS, or that they'll arrange building regulations sign-off another way, because you'll need a compliance certificate when you sell. Ask for proof of public liability insurance and a clear guarantee, ideally insurance-backed. Get at least two or three quotes. Prices for the same job can differ by hundreds of pounds, and the cheapest isn't always the one using the better glass or the tidier finish.
How We Select & Rate The Best Window Installers in Swindon
Businesses are ranked mainly by public review rating and review count drawn from third-party business listings, with a small lift for those showing a working website and phone number.

Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. Every other listing is ranked on rating and review count from third-party business listings. How we rank & verify →

Transparency notice: Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. All other listings are ranked by a combined score drawn from ratings and review counts published on third-party business listings, plus basic completeness signals such as a working website and phone.

For a typical three-bed semi in Swindon, expect roughly £3,500 to £7,000 for a full set of white uPVC double glazed windows, depending on how many openings you have and the glass spec. Individual casement windows usually start around £300 to £600 fitted, with tilt-and-turn, bay windows and coloured or woodgrain finishes costing more. Aluminium and timber sit well above uPVC, and a bay can add £1,500 or more. Triple glazing, trickle vents, and whether old units are taken away all move the price. Getting two or three itemised quotes is normal and worth the effort.
Do I need planning permission to replace my windows?
Usually not. Like-for-like replacement on most houses falls under permitted development. The exceptions are listed buildings, properties in a conservation area where an Article 4 direction applies, and some flats and leasehold properties where the freeholder controls the exterior. Parts of Old Town and the Railway Village have heritage constraints, so check with Swindon Borough Council before you order anything. If you're unsure, ask your installer to confirm in writing.
What's the difference between uPVC, aluminium and timber windows?
uPVC is the cheapest, low maintenance and fine for most estate homes. Aluminium has slimmer frames, lasts a long time and suits modern extensions, but costs more. Timber looks right on period properties and can be repaired, though it needs repainting every few years. Composite frames combine a timber interior with an aluminium exterior and sit at the top of the price range.
How long does a full window replacement take?
A typical house takes one to two days to fit once the windows are made. The lead time is the longer part. Made-to-measure units normally take three to eight weeks to arrive, longer for aluminium or bespoke timber. A survey visit comes first, where the installer measures every opening. Expect some dust and noise, and clear furniture away from the windows beforehand.
What guarantees and paperwork should I get?
You should receive a compliance certificate (for example from FENSA or CERTASS, or a building control completion certificate) and a written guarantee. Ten years on frames and glazing is common, but check what it covers: seals, hinges, handles and labour can all differ. Ask whether the guarantee is insurance-backed, so it still stands if the company stops trading. Keep everything with your house documents, because a buyer's solicitor will ask for it.
How do I check and choose between window installers?
Start with the basics. Ask to see proof of relevant trade accreditation and check it with the scheme itself, ask for a copy of their public liability insurance, and look up the company on Companies House if they're a limited company. Read recent online reviews, including the less glowing ones, and see how the business replied. Ask for addresses of recent local jobs you could look at. Then compare quotes line by line: same glass spec, same frame profile, same extras. Avoid anyone who demands a large upfront payment or pressures you with a time-limited discount. A deposit of 10 to 25 per cent is more usual, with the balance on completion.
