Hertfordshire: walls, weather and approvals
The East of England has a mix of post-war estates, inter-war semis and older solid brick and flint cottages, with some system-built council homes on post-war estates.
Much of Hertfordshire sits in the lower wind-driven rain exposure bands, which keeps the choice of finishes wide — though hilltop, coastal and exposed gable walls can still need a tougher specification, so we check the actual site.

Planning and building control in England
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. Planning permission is usually needed in conservation areas, National Parks, National Landscapes, the Broads and World Heritage Sites (where cladding a house in stone, artificial stone, pebble dash, render, timber, plastic or tiles isn't permitted development), for flats and maisonettes, for commercial buildings, under an Article 4 direction, or where the look changes noticeably. Listed buildings need listed building consent.
Renovating more than half of a wall's area — insulating it, or stripping and re-rendering it — or more than a quarter of the building's whole external envelope brings in the energy requirements of Part L, so building control needs to be involved and the wall should reach about 0.30 W/m²K where that's technically, functionally and economically feasible.
What's involved in stripping old render?
The render is hacked off, usually with breakers, and the debris bagged or skipped. The wall is then inspected: loose bricks, eroded mortar and damp spots are repaired, and the surface is prepared to suit the new system.

Re-rendering in Hertfordshire: questions
Do I need building control for re-rendering?
In England and Wales, re-rendering more than half of a wall's area — or more than a quarter of the whole building's envelope — is controlled work under Part L, so usually yes. We explain how it's handled in the quote.
Is it worth adding insulation?
On solid or concrete walls it's usually the most cost-effective time to do it, because access and preparation are already paid for.
Can I re-render just one wall?
Yes, though matching colour and texture to the other walls may mean recoating them too.
Do you cover all of Hertfordshire?
Yes. We survey and quote re-rendering across Hertfordshire, including Watford, Stevenage, Hemel Hempstead, St Albans, Welwyn Garden City.
Do I need planning permission in England?
