How we approach sliding rooflights in London
Our sliding rooflights service in London covers box rooflights whose glass lid slides back for walk-out roof access. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Typical uses for sliding rooflights include staircases that rise to a roof terrace.
London is the main town we list in Greater London; we also cover nearby Pimlico and Islington.

Planning and building rules for London
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Common questions
Does it need planning permission?
A box unit that projects above the roof plane can need planning permission, especially on the front of a house or in a conservation area. We check before you order.
Can children open it?
Controls can be key-switched or placed out of reach. We will set the controls up to suit the household.
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
Can you work alongside my builder in London?
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 London?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
