How we approach skylight installation in Lancaster
Skylight installation in Lancaster means survey, supply and fit — new openings, extensions and fit-only work. We cover the LA1 district and the rest of Lancashire, with a survey before any price is fixed.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. Skylight installation suits builders' projects and retrofits into finished roofs.
Lancaster sits about 5 km from Morecambe and 19 km from Fleetwood, and we cover the whole LA1 postcode district and the roads in between.

Planning, building control and Lancaster
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Our planning guide covers each nation in more detail.

Questions about skylight installation in Lancaster
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.
Do you fit rooflights bought elsewhere?
Yes. We check the product and the opening first, and our workmanship terms cover the fitting rather than the product.
Is the survey free?
Yes, for new installations. Repair visits are charged.
Do I need to be at home for the survey in Lancaster?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
