Building Regulations for rear extensions in Staffordshire
Construction drawings, structural calculations and building control through to the completion certificate. Across Staffordshire we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Stoke-on-Trent, Newcastle under Lyme and Burton upon Trent.
Staffordshire has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.
What does it cost in Staffordshire?
As a guide, £2,500–£5,500 including VAT. These are guide ranges; the written quote after the survey is the figure that counts.
What approvals does it need in Staffordshire?
Every rear extension in England needs Building Regulations approval, whether or not planning is needed. You can use the council's building control service or a registered building control approver, by full plans (checked before work, usually within five weeks) or a building notice, and you get a completion certificate at the end.
New fabric must meet Approved Document L (2021 edition incorporating 2023 amendments): walls 0.18, roof 0.15 and floor 0.18 W/m²K, windows 1.4 W/m²K or Band B. Under the simple route, new windows, doors and rooflights should not exceed 25% of the extension floor area plus any openings removed; more glass is possible with a whole-house calculation.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent.
