What we fit in Bolton
From flat-roof extensions to period slate roofs, we fit the right rooflight for the building in Bolton — after a survey, with a fixed written price.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement.
We work across Greater Manchester, including Bolton, and in neighbouring towns such as Farnworth and Westhoughton. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning and building rules in England
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. 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.

Skylight questions: Bolton
Do I need to be at home for the survey in Bolton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Bolton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Bolton?
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.
Is the survey in Bolton free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do you take a deposit?
Nothing is paid until you accept a written quote. Made-to-measure products are ordered after you accept, we tell you in writing when the order is placed, and the quote states the payment stages.
Can a skylight be fitted into an existing flat roof?
Yes. We form the opening, trim joists, build an insulated upstand, re-waterproof and make good the ceiling.
