Skylight installation for Accrington: the essentials
Skylight installation in Accrington means survey, supply and fit — new openings, extensions and fit-only work. We cover the BB5 district and the rest of Lancashire, with a survey before any price is fixed.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. In Accrington, as anywhere, skylight installation is the usual choice for new extensions, new openings and fit-only jobs.
From Accrington to Rawtenstall, Blackburn and Darwen, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Accrington
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

Common 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 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.
Will I need planning permission in Accrington?
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.
Do I need to be at home for the survey in Accrington?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
