Exeter housing stock considerations
- Victorian terraces (common in St David’s, Heavitree, St Leonard’s): often require sash-style windows to match original character — 40-60% more than casement uPVC
- 1930s semis (Topsham, Pinhoe, Whipton): standard casement style — the most cost-effective replacement
- Conservation areas (Central Exeter, St Leonard’s, Topsham): may require planning permission and wooden frames — budget +30-60%
- Detached properties (Topsham, Pennsylvania, Duryard): typically 10-14 windows; aluminium is a common choice for modern detached stock

Exeter double glazing — homeowner FAQs
Do I need planning permission in Exeter?
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 Exeter, St Leonard’s, Topsham), Article 4 directions may apply to front-elevation changes. Check with your council before ordering.
Are Exeter 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 Exeter?
Qualifying households may receive fully funded or subsidised windows via ECO4. See our ECO4 guide.
How long does installation take in Exeter?
A typical Exeter 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 Exeter around 2% below the UK average?
Regional labour rates, local installer competition, and proximity to UK uPVC and aluminium fabricators all factor in. Exeter’s position reflects lower labour rates than London and the South-East, and strong local installer competition.
