Planning and building rules for Chippenham
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. 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.

Rooflight upstands & kerbs in Chippenham: questions

If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.

Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.

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 Chippenham free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
