How we approach skylight replacement in Milton Keynes
We handle skylight replacement across Buckinghamshire, including Milton Keynes. 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.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Skylight replacement suits older extensions due a modern rooflight.
Milton Keynes is the main town we list in Buckinghamshire; we also cover nearby Bletchley and Leighton Buzzard.
What you can choose
- Misted glass unit replacement only
- Fixed to electric opening
- Upstand rebuild and insulation
- Dome to flat glass upgrade
- Roof window replacement in pitched roofs
- Better thermal performance
- Option to add opening and rain sensor
Before you order: points to check
- Upstand and roof condition decide the scope
- Old glass and domes are disposed of responsibly
Consents for skylight replacement in Milton Keynes
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
