Pricing in Minutes, Not Days
You shouldn't have to wait a week and sit through a sales visit just to find out what windows cost. With Prime Sash Windows you get a real number straight away. Enter your sizes and specification online and our calculator prices it instantly — then, when you're happy, send it to us in one click for a firm, confirmed quote.
How Your Instant Quote Works
- Price it yourself, online. Enter your window sizes and spec and see a guide price in minutes — free and with no obligation.
- Send it for a firm quote. Happy with the figure? One click sends it to us and we confirm it.
- Book a survey when ready. For installation we measure on site so the final price is exact. No pressure at any step.
Why Instant Beats Waiting
- Speed — a real figure in minutes instead of a callback next week.
- No sales pressure — you're in control; we don't cold-call or chase you.
- Transparent — itemised pricing, so you see exactly where every pound goes.
- Anytime — quote at 11pm on a Sunday if that suits you; the calculator never closes.

Instant Window Quote — FAQ
How quickly can I get a window quote?
Instantly. Our online calculator gives you an itemised guide price in minutes — no waiting for a callback or a sales appointment.
Is the instant quote the same as a firm quote?
The instant figure is an accurate guide. We confirm it as a firm quote after a quick check, and a site survey if we're installing.
Will I get a sales call?
No. We don't cold-call or chase you. You're in control and only contact us when you're ready.
Is there any obligation?
None at all. Price as many projects as you like, as often as you like, and only proceed when it suits you.
Can I get an instant quote for doors too?
Yes — french, bifold, sliding and entrance doors price through the same tool, alongside your windows.
