Understanding The Market
Why Window Prices Vary So Much
One of the biggest frustrations for homeowners is receiving completely different quotes for the same job. It's not unusual for quotes to vary by £2,000 – £5,000.
This happens because several factors affect the final cost:
- Window frame material
- Glass specification
- Installation quality
- Company overheads
- Guarantees and certifications
The cheapest quote isn't always the best option.
Poor-quality windows or rushed installations can lead to condensation between glass panes, draughts and heat loss, poor locking mechanisms, and frames warping or failing.

The 3 Biggest Mistakes Homeowners Make
Choosing The Cheapest Quote
Low prices often mean cheaper frames, lower quality glass, and rushed installation — leading to problems within a few years.
Not Checking Installation Quality
Even the best windows will fail if installed poorly. Professional installers should ensure proper sealing, secure locking systems, and meet current building regulations.
Ignoring Guarantees
Reputable installers provide long-term guarantees on frames, glass units, and installation work. Always confirm warranty details before proceeding.
