How we approach hinged roof access rooflights in Hounslow
Our hinged roof access rooflights service in Hounslow covers hinged glazed hatches over a stair or ladder for roof terrace access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. In Hounslow, as anywhere, hinged roof access rooflights are the usual choice for reaching a roof terrace, plant area or flat roof from a stair or ladder.
Neighbouring towns include Isleworth (1 km) and Twickenham (3 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Hounslow?
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. 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
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.
Will I need planning permission in Hounslow?
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.
Can you work alongside my builder in Hounslow?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
