How we approach frameless structural rooflights in Colne
We handle frameless structural rooflights across Lancashire, including Colne. In short: minimal glass rooflights with no visible frame from inside. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. Typical uses for frameless structural rooflights include architect-led extensions and long slots of light over islands or along party walls.
Colne sits about 3 km from Nelson and 8 km from Burnley, and we cover the whole BB8 postcode district and the roads in between.
Specification options

Before you order: points to check
- Tolerances are tight — the opening must be built square and to size
- Large panes need lifting gear and access planning
Planning, building control and Colne
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.
Read the planning permission guide before you commit to a design.

Common questions
Does it cost more?
Usually, because the glass is larger and heavier and the finish needs tighter tolerances. The price table shows typical ranges.
Will I see the edge of the glass?
From inside, the reveal is finished up to the glass so the edge is hidden. From outside you will see the glass and its edge seal.
How is it lifted onto the roof?
Larger panes go up with a vacuum lifter, a hoist or a crane. We plan access at survey.
Can you work alongside my builder in Colne?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Colne free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
