Roof lanterns in Kingston upon Thames: what is involved?
Roof lanterns in Kingston upon Thames means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the KT1 district and the rest of Greater London, with a survey before any price is fixed.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Typical uses for roof lanterns include rooms that need height as well as light.
Kingston upon Thames sits about 3 km from Twickenham and 3 km from Richmond, and we cover the whole KT1 postcode district and the roads in between.

Consents for roof lanterns in Kingston upon Thames
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.
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.
