Glass links & glass box roofs for Preston: the essentials
We handle glass links & glass box roofs across Lancashire, including Preston. In short: frameless glass links joining old and new buildings. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Exposed hillside towns in the North West need flashing and seal details that cope with wind-driven rain. In Preston, as anywhere, glass links & glass box roofs are the usual choice for joining a period house to a new extension or annexe.
Preston is the main town we list in Lancashire; we also cover nearby Leyland and Chorley.

Planning and building rules for Preston
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
See our building regulations guide for U-values, glazing limits and self-certification.
