Conservation rooflights in Bolton: what is involved?
For Bolton homes and buildings we offer conservation rooflights: slim, low-profile steel-look rooflights for period and listed roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Converted mills and warehouses in the North West often have large rooflights or glass roofs that need specialist replacement. Typical uses for conservation rooflights include period, listed and conservation-area roofs.
Bolton is around 17 km from Manchester, and we survey and fit throughout that part of Greater Manchester, including the BL1 district.

Planning and building rules for Bolton
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
See our building regulations guide for U-values, glazing limits and self-certification.
