What does skylight replacement in Cirencester involve?
We handle skylight replacement across Gloucestershire, including Cirencester. In short: replacing tired domes and failed glass with a modern rooflight. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Barn and chapel conversions in the South West often need bespoke or shaped rooflights to suit the original structure. Typical uses for skylight replacement include older extensions due a modern rooflight.
Cirencester is around 25 km from Gloucester, and we survey and fit throughout that part of Gloucestershire, including the GL7 district.

Planning, building control and Cirencester
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

Skylight replacement in Cirencester: questions
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
Can you work alongside my builder in Cirencester?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Cirencester?
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof.
