Hinged roof access rooflights in Carshalton: what is involved?
For Carshalton homes and buildings we offer hinged roof access rooflights: hinged glazed hatches over a stair or ladder for roof terrace access. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Think of hinged roof access rooflights for reaching a roof terrace, plant area or flat roof from a stair or ladder.
Carshalton sits about 1 km from Wallington and 1 km from Sutton, and we cover the whole SM5 postcode district and the roads in between.

Do you need permission in Carshalton?
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. 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.

Common questions
Electric or manual?
Gas-strut hatches are simple and reliable. Electric hatches suit heavier lids, wider openings and anyone who would struggle to push a lid up.
Can it be opened from the roof?
Many units have an external handle or key for opening from outside. If you need that, tell us at survey.
Does it let in as much light as a normal rooflight?
Yes — closed, it is a glazed rooflight. The frame is slightly deeper to carry the hinge and seals.
