Homes and walls in Derby
As well as Derby itself, we quote in Belper, Ilkeston and Heanor.
Housing in the East Midlands includes Victorian terraces in the towns and cities, plenty of inter-war semis and post-war council estates, some of them system-built.
Exposure to wind-driven rain varies across Derbyshire: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.

Approvals in England
For a house in Derby, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.

Do you cover Derby?
Yes — we survey and quote in Derby (DE1) and nearby Belper, Ilkeston and Heanor.
How much does external wall insulation cost in Derby?
Our guide is £105–£170 per m² depending on the system, plus scaffolding — roughly £10,200–£17,700 for a typical three-bed semi with EPS and silicone render. Installing insulation in a home is zero-rated for VAT until 31 March 2027, so that's the total. A free survey fixes the price.
Do I need planning permission in Derby?
Planning in Derby follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
Is VAT charged on wall insulation?
Installing wall insulation in homes is zero-rated until 31 March 2027, then 5%, so our insulation prices are totals. Render-only work and repairs carry VAT at 20%, and our prices for them include it.
