How we approach skylight replacement in King's Lynn
We handle skylight replacement across Norfolk, including King's Lynn. 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 conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. In King's Lynn, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
We work across Norfolk, including King's Lynn, and in neighbouring towns such as Wisbech and March. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Misted glass unit replacement only
- Dome to flat glass upgrade

Before you order: points to check
- Old glass and domes are disposed of responsibly
- Upstand and roof condition decide the scope
Planning, building control and King's Lynn
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
Read the planning permission guide before you commit to a design.
