Skylight replacement for Clevedon: the essentials
We handle skylight replacement across Somerset, including Clevedon. 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Typical uses for skylight replacement include yellowed domes, misted glass and leaking roof windows.
Clevedon sits about 7 km from Nailsea and 8 km from Portishead, and we cover the whole BS21 postcode district and the roads in between.

- Dome to flat glass upgrade
- Upstand rebuild and insulation
- Misted glass unit replacement only
- Like-for-like size replacement

Things we check at survey
- A replacement is a chance to meet current thermal standards
- Upstand and roof condition decide the scope
Do you need permission in Clevedon?
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. 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.

Skylight replacement in Clevedon: questions
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
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.
Will I need planning permission in Clevedon?
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.
Is the survey in Clevedon free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
