How we approach skylight installation in Preston
Our skylight installation service in Preston covers survey, supply and fit — new openings, extensions and fit-only work. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Think of skylight installation for builders' projects and retrofits into finished roofs.
We cover all of Preston and the PR1 district, and nearby Leyland and Chorley.

Do you need permission in Preston?
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
Read the planning permission guide before you commit to a design.
