What do sliding rooflights in Greenwich involve?
For Greenwich homes and buildings we offer sliding rooflights: box rooflights whose glass lid slides back for walk-out roof access. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of sliding rooflights for walk-out access where a hatch would feel cramped.
We work across Greater London, including Greenwich, and in neighbouring towns such as Blackheath and Lewisham. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Greenwich
- Rain sensor
- Electric drive with safety edge
- Integrated balustrade on some ranges

Things we check at survey
- Needs space on the roof for the lid to slide clear
- Electric units need a dedicated supply and commissioning
Do you need permission in Greenwich?
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. 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.

Sliding rooflights in Greenwich: 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.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
Is it lockable?
Yes. Units lock from inside and the drive holds the lid closed.
Is the survey in Greenwich free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Greenwich?
