What will new windows cost?
A starting figure before the salesman calls. Pick how many windows you're replacing, the frame and the glazing, and your region — and we give you an indicative UK fitted price range, with the usual add-ons broken out. Window prices are notoriously inflated and then 'discounted' on the doorstep; a budget to walk in with protects you. Free, no sign-up.
A guide, not a quote. The ranges are typical 2025/26 UK fitted prices — the frames, the glazing and the fitter's labour, inclusive of VAT — drawn from published industry averages. They exclude structural openings, internal making-good and plastering, very large or feature glazing, and listed-building work. Every job is different: the only real number is a measured, written quote from a FENSA or CERTASS-registered installer, and you should get at least three. Nothing you type leaves your browser.
The frame and glazing set the price; the count and access set the total.
uPVC, aluminium or timber. uPVC is the value choice and the most efficient for the money — it fits most homes. Aluminium is slim, strong and modern-looking, but costs noticeably more. Timber suits period and conservation-area homes and looks the part, but is the dearest option and needs repainting every few years to keep it weathertight.
Double or triple glazing. Good double glazing is the right call for most homes. Triple glazing adds a third pane for roughly 20% more, improving insulation and sound-proofing — it earns its keep on very exposed, cold or noisy elevations more than as a blanket whole-house upgrade, where the extra outlay rarely pays back.
What drives the whole-house figure. The total is the number of windows times an average per-window price — but real homes mix small, medium and one or two large or bay windows, so the average matters. Access counts too: upstairs windows on a two-storey home almost always need scaffolding or a tower, which is easy to leave off a headline price and add later.
The sales tactics — and how to protect yourself. Replacement-window selling is notorious for inflated 'list' prices and big 'today only' discounts designed to make you sign on the first visit. Get three written quotes, never sign on the doorstep, and treat any one-night-only deal as a warning sign. A budget worked out in advance is the simplest defence against a pressured sale.
FENSA, CERTASS and Building Regs. Replacement windows must meet Building Regulations for energy efficiency. Using a FENSA or CERTASS-registered installer means the work self-certifies — you get a certificate confirming it complies, without a separate building-control application. Keep that certificate safe: a buyer's solicitor will ask for it when you sell.
Keep your windows' details in one place.
Stead holds the installer, the FENSA certificate, the glazing guarantee and its expiry alongside the rest of your home's record — so the cover doesn't lapse, and the paperwork's to hand for a claim or a sale.
