What does skylight replacement in St Neots involve?
Thinking about skylight replacement in St Neots? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. Think of skylight replacement for yellowed domes, misted glass and leaking roof windows.
St Neots is around 40 km from Peterborough, and we survey and fit throughout that part of Cambridgeshire, including the PE19 district.

Do you need permission in St Neots?
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.
