How we approach skylight installation in Bletchley
For Bletchley homes and buildings we offer skylight installation: survey, supply and fit — new openings, extensions and fit-only work. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Period cottages and conservation-area streets are common in the South East, so slim conservation rooflights are often the right choice. In Bletchley, as anywhere, skylight installation is the usual choice for new extensions, new openings and fit-only jobs.
Bletchley sits about 6 km from Milton Keynes and 10 km from Leighton Buzzard, and we cover the whole MK3 postcode district and the roads in between.

Planning and building rules for Bletchley
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 installation in Bletchley: questions
Is the survey free?
Yes, for new installations. Repair visits are charged.
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Who handles building control?
We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.
Can you work alongside my builder in Bletchley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Bletchley?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
