Roof lanterns and rooflights for rear extensions in Bedfordshire
Lanterns, flat rooflights and walk-on glass that bring light deep into the plan. Rear extensions in Bedfordshire: we cover 11 towns including Luton, Bedford and Dunstable, with design, approvals and the build under one contract.
Rear extensions in Bedfordshire gain most from a rooflight placed against the old back wall, where the room would otherwise be darkest. Bedfordshire mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.
What does it cost in Bedfordshire?
As a guide, £2,200–£4,500 including VAT. We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
What approvals does it need in Bedfordshire?
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.
