Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens.

Planning and building rules in England
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.
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
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.
Is it secure?
Units lock from inside. As with any rooftop door, keep it locked when the house is empty.
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.

Yes. We survey and fit hinged roof access rooflights across West Sussex, including Crawley, Worthing, Bognor Regis.
