| Property type | Windows | uPVC total | Aluminium total |
|---|---|---|---|
| Flat / apartment (DE) | 3-5 | £1,400 – £2,600 | £2,000 – £3,700 |

Derby housing stock considerations
- Victorian terraces (common in Allenton, Normanton, Pear Tree): often require sash-style windows to match original character — 40-60% more than casement uPVC
- 1930s semis (Mickleover, Oakwood, Chaddesden): standard casement style — the most cost-effective replacement
- Conservation areas (Strutts Park, Friar Gate, Little Chester): may require planning permission and wooden frames — budget +30-60%
- Detached properties (Duffield, Mickleover, Quarndon): typically 10-14 windows; aluminium is a common choice for modern detached stock

Derby double glazing — homeowner FAQs
Do I need planning permission in Derby?
Most like-for-like replacements don’t need planning permission — your FENSA-registered installer handles Building Regs compliance automatically. For work in conservation areas (Strutts Park, Friar Gate, Little Chester), Article 4 directions may apply to front-elevation changes. Check with your council before ordering.
Are Derby 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 Derby?
Qualifying households may receive fully funded or subsidised windows via ECO4. See our ECO4 guide.
How long does installation take in Derby?
A typical Derby 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 Derby around 7% below the UK average?
Regional labour rates, local installer competition, and proximity to UK uPVC and aluminium fabricators all factor in. Derby’s position reflects lower labour rates than London and the South-East, and strong local installer competition.

Compared 4 quotes in under 10 minutes. Gap between cheapest and most expensive was £2,300 for identical spec. Would have been totally lost going direct.
Only got 3 quotes back instead of 4, which was a bit disappointing, but the three were all solid and the one I picked did a great job. Transparent pricing, no haggling nonsense.
Conservatory roof replacement in Solihull. Four quotes ranged £6,800 to £11,500 for identical spec. Went with the middle one — 30% cheaper than I'd been quoted by a national brand.
