Skylight installation for Grantham: the essentials
We handle skylight installation across Lincolnshire, including Grantham. In short: survey, supply and fit — new openings, extensions and fit-only work. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Bungalows are common across parts of the Midlands, and sun tunnels or roof windows are a quick way to brighten internal hallways. Skylight installation suits builders' projects and retrofits into finished roofs.
Neighbouring towns include Newark-on-Trent (21 km) and Melton Mowbray (23 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Grantham?
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.
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.
Read the planning permission guide before you commit to a design.
