Hinged roof access rooflights in New Malden: what is involved?
Thinking about hinged roof access rooflights in New Malden? The short answer: hinged glazed hatches over a stair or ladder for roof terrace access. The longer answer depends on your roof, which is why we survey before we 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. Typical uses for hinged roof access rooflights include occasional roof access that also lights the stair.
New Malden is around 15 km from central London, and we survey and fit throughout that part of Greater London, including the KT3 district.
Specification options
- Hinge side to suit the stair
- Grab rail or handle inside
- Rain sensor on electric versions
- Manual gas-strut or electric opening
- Frame colour options
- Lockable from inside
- Insulated frame and double or triple glazing
What to check first
- Electric versions need a supply and a safety check
- The lid must open clear of parapets and balustrades
Planning and building rules for New Malden
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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.

Hinged roof access rooflights in New Malden: 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.
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.
Can you work alongside my builder in New Malden?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in New Malden?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
