How much do new windows cost in Cheltenham? A 2025 price guide.
Here’s what to expect…
If you’ve started looking into replacing your windows, you’ll know it can be a bit of a minefield. One company will quote you £1,200 for a single window, another says they can do your whole house for less. So, what’s the real story? And what should you expect to pay in Cheltenham in 2025?
I’ve been fitting windows for over 25 years, and if there’s one thing I can’t stand, it’s people being overcharged. The big national companies often add on huge overheads and pushy sales tactics that leave homeowners paying far more than they need to. This guide will give you a clear, no-nonsense idea of what new windows actually cost — so you can budget properly and avoid getting taken for a ride.
Average cost of new windows in 2025
The price of a new uPVC double-glazed window in Cheltenham usually falls between:
£400–£650 per window (supply + installation, standard size).
£3,500–£7,500 for a typical 3-bed semi-detached house (8–10 windows).
That’s for straightforward replacements. Costs can shift depending on:
Frame material: uPVC is cheapest, aluminium is more expensive but modern-looking and durable, timber sits at the top end.
Glazing type: Double glazing is standard; triple glazing adds ~20–30% on top.
Size & style: A small casement window is cheaper than a large bay or sash window.
Access: Upstairs windows or tricky locations may need scaffolding, adding to the bill.
What about doors?
uPVC front/back door: £650–£950 fitted.
Composite front door: £1,100–£1,800 fitted.
French/patio doors: £1,200–£2,000 depending on size and material.
Bifold doors: £3,000+ depending on span and glazing.
Conservatory costs (for context)
Many homeowners looking at new windows are also thinking about their conservatory. Rough ballparks:
Conservatory roof replacement: £3,000–£7,000 depending on size and materials.
Full conservatory installation: £12,000–£25,000+.
Repair vs replacement
If your windows are draughty, stiff, or have misted glass, it doesn’t always mean you need a full replacement.
Glass unit replacement: £120–£200 per window.
New hinges/handles: £50–£120.
Often, repairs can buy you another 5–10 years before full replacement is needed.

Final word
Replacing your windows isn’t cheap, but it also shouldn’t cost the earth. In Cheltenham, fair, competitive pricing is out there — you just need to know what to look for. My advice: don’t be rushed by sales tactics, compare quotes carefully, and work with someone who values a job done properly at the right price.
