What are hinged roof access rooflights?
Across Cornwall, our hinged roof access rooflights work covers hinged glazed hatches over a stair or ladder for roof terrace access. Survey first, fixed price second, fitting third.
Stone cottages, slate roofs and conservation areas are common in the South West, and conservation-profile rooflights keep the roofline quiet. Holiday lets and second homes across the South West often want roof windows with blinds and remote opening for when the house is empty.

Planning and building rules in England
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. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

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.
How big does an access hatch need to be?
Big enough to climb through comfortably for the stair or ladder you have. For a stair, we size it to the stair width and the headroom; for occasional plant access a smaller hatch can work.
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.
Can it replace an old loft hatch?
Where there is a flat roof above, yes. On a pitched roof, an access roof window is the equivalent.
Do you fit hinged roof access rooflights across Cornwall?
Yes. We survey and fit hinged roof access rooflights across Cornwall, including Redruth, Falmouth, St Austell.
