Whole-house double glazing
What can change a real Cambridge quote?
- Casement, sash, sliding, tilt-and-turn, bay or bow style
- Window dimensions and opening configuration
- uPVC, aluminium or timber frame specification
- Double versus triple glazing
- Number of windows in the order
- Scaffolding or difficult access
- Making good around the openings
Local planning considerations
Local labour demand, restricted central access and higher-specification property work can move real quotations outside the broad East of England planning range.
- Central access and delivery constraints can add logistics that are not captured by a simple regional multiplier.
- Check heritage, conservation or listed-building requirements before budgeting standard external alterations or replacement windows.
- Professional fees and specification choices can outweigh the regional factor on extensions, structural work and high-finish refurbishments.
How the regional model works
The broad East of England factor is 1.08×, but the live window calculator applies only 30% of that regional difference because replacement-window pricing has a large manufactured-product component. The resulting Cambridge window factor is 1.024×.

Frequently asked questions
How much do replacement windows cost in Cambridge in 2026?
Current double-glazing benchmarks run from about £500 for a basic casement to £5,000+ for larger specialist bow windows. A typical 3-bedroom whole-house project is around £8,000–£15,000 nationally; the modelled Cambridge range is £8,200–£15,350.
How much do 10 casement windows cost in Cambridge?
The national casement benchmark is £500–£1,250 per window. For 10 windows, the calculator's moderated regional factor gives £5,100–£12,800, before triple-glazing or scaffolding allowances.
Why is the Cambridge window factor smaller than the general regional factor?
Frames and glazing units contain a substantial nationally priced manufacturing component, so the calculator applies only 30% of the broad regional difference.
What can increase a window replacement quote?
Sash, bay and bow windows, aluminium or timber frames, triple glazing, upgraded security glass, difficult access, scaffolding and repairs to existing openings can increase the total.
