How we approach skylight installation in Formby
Skylight installation in Formby means survey, supply and fit — new openings, extensions and fit-only work. We cover the L37 district and the rest of Merseyside, 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.
Formby sits about 10 km from Maghull and 10 km from Southport, and we cover the whole L37 postcode district and the roads in between.

Planning, building control and Formby
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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. 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.

Skylight installation in Formby: questions
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.
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
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.
Will I need planning permission in Formby?
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.
