How we approach frameless structural rooflights in Dunstable
Frameless structural rooflights in Dunstable means minimal glass rooflights with no visible frame from inside. We cover the LU6 district and the rest of Bedfordshire, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of frameless structural rooflights for rooms where you want sky without a visible frame.
Dunstable sits about 7 km from Luton and 10 km from Leighton Buzzard, and we cover the whole LU6 postcode district and the roads in between.

Do you need permission in Dunstable?
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.

Common questions
Can it open?
Some frameless designs include a sliding or hinged opening element, but most are fixed. Pair with an opening unit if you need ventilation.
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.
Can a frameless rooflight be walked on?
Only if it is specified as a walk-on unit. Most frameless rooflights are for light only.
Is the survey in Dunstable free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Dunstable?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
