How we approach skylight installation in Chorley
Our skylight installation service in Chorley 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.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. In Chorley, as anywhere, skylight installation is the usual choice for builders' projects and retrofits into finished roofs.
We work across Lancashire, including Chorley, and in neighbouring towns such as Leyland and Darwen. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Chorley

What to check first

Do you need permission in Chorley?
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.
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. 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.

Questions about skylight installation in Chorley
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.
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.
How long does installation take?
Fitting into a prepared upstand takes about a day. A new opening in an existing roof, including making good, often takes two to three days.
How do I book a survey in Chorley?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Chorley?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
