Roof lanterns and rooflights for rear extensions in Worcestershire
Lanterns, flat rooflights and walk-on glass that bring light deep into the plan. Rear extensions in Worcestershire: we cover 8 towns including Worcester, Redditch and Kidderminster, with design, approvals and the build under one contract.

Rear extensions in Worcestershire gain most from a rooflight placed against the old back wall, where the room would otherwise be darkest. Red-brick terraces and 1930s semis make up much of Worcestershire. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.
What does it cost in Worcestershire?
As a guide, £2,200–£4,500 including VAT. Ground conditions, glazing, the roof and how far the house is opened up move the final figure within the range.
What approvals does it need in Worcestershire?
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.
