Honest pricing.
Made in Britain.
We make windows and doors in the UK and sell them direct — without the high-street markup, the commission-paid sales reps, or the high-pressure home visits.
Who we are
Fast Windows & Doors is part of the S&K Group — a family of UK glazing and trade businesses with over 20 years of combined experience supplying made-to-measure windows, doors, conservatories and shopfronts across the United Kingdom.
We started this site for one simple reason: buying windows shouldn't be hard. The traditional model — endless quote forms, sales-rep visits, "today only" discounts — wastes everyone's time and pushes prices up. We sell the same A++ rated, FENSA-approved products at the price you see on screen.
What makes us different
- Real prices, online. Configure your product, see the price, order. No haggling.
- Made in Britain. Every window and door is manufactured at our partner factories in the West Midlands and Yorkshire.
- Two ways to order. Supply-only for DIY-ers and trades; supply & install for full-service customers.
- FENSA approved. Every install comes with full Building Regs certification.
- 10-year guarantee. On every frame, glass unit and installation.
Our standards
Every product we sell meets or exceeds:
- BS EN 14351-1 (Windows & doors — performance)
- PAS 24:2016 (Enhanced security)
- Building Regulations Part L (Energy efficiency)
- Building Regulations Part Q (Security in dwellings)
- Secured by Design (where specified)
