Skylight installation for Alnwick: the essentials
Our skylight installation service in Alnwick 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.
Older flat-roofed extensions in the North East are often due a new roof covering — the right time to upgrade the rooflight too. Skylight installation suits builders' projects and retrofits into finished roofs.
From Alnwick to Morpeth, Ashington and Blyth, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Alnwick
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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. 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.
Read the planning permission guide before you commit to a design.
