Cambridge housing stock considerations
- Victorian terraces (common in Petersfield, Romsey, Newnham): often require sash-style windows to match original character — 40-60% more than casement uPVC
- 1930s semis (Trumpington, Cherry Hinton, Arbury): standard casement style — the most cost-effective replacement
- Conservation areas (Central Cambridge, Newnham, Fitzroy): may require planning permission and wooden frames — budget +30-60%
- Detached properties (Trumpington, Grantchester, Storey’s Way): typically 10-14 windows; aluminium is a common choice for modern detached stock

Cambridge double glazing — homeowner FAQs
Do I need planning permission in Cambridge?
Most like-for-like replacements don’t need planning permission — your FENSA-registered installer handles Building Regs compliance automatically. For work in conservation areas (Central Cambridge, Newnham, Fitzroy), Article 4 directions may apply to front-elevation changes. Check with your council before ordering.
Are Cambridge installers FENSA-registered?
Yes — every installer Findfitter matches must be FENSA-registered (or equivalent). You receive a 10-year insurance-backed guarantee and automatic compliance notification with every install.
Can I get grants for double glazing in Cambridge?
Qualifying households may receive fully funded or subsidised windows via ECO4. See our ECO4 guide.
How long does installation take in Cambridge?
A typical Cambridge semi with 8-10 windows is fitted in 1-2 days by a two-person team. Lead time from order to install is typically 4-6 weeks for standard uPVC, 6-8 weeks for aluminium, and 8-12 weeks for heritage sash.
Why is Cambridge around 12% above the UK average?
Regional labour rates, local installer competition, and proximity to UK uPVC and aluminium fabricators all factor in. Cambridge’s position reflects higher labour rates typical of the region.

From homeowners like you
Was dreading pushy salesmen. Instead got three polite, short calls and a written quote within 48 hours. Went with the local fitter — itemised breakdown, no pressure, 20-year frame warranty.
Tenement flat in the West End — a lot of installers wouldn't quote because of access, but Findfitter matched me with one who specialises in G1-G3 flats. Spot on.
Replaced 3 windows and the front door after our L-postcode terrace survey. The FENSA installer spotted a lintel issue the others missed and priced the proper fix in. Job done.
