Roof lanterns for Bexleyheath: the essentials
Our roof lanterns service in Bexleyheath covers hipped glass lanterns that lift the ceiling of orangeries and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Typical uses for roof lanterns include rooms that need height as well as light.
Bexleyheath is around 19 km from central London, and we survey and fit throughout that part of Greater London, including the DA6 district.
Options we can specify in Bexleyheath
- LED lighting in the plaster box
- Aluminium or uPVC systems
- Opening vents with electric control
- Solar-control or self-cleaning glass

What to check first
- Some designs project above the roof enough to affect planning on certain houses
- Plaster-box depth affects how the lantern looks from below
Planning, building control and Bexleyheath
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. 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.

- Installation day. Usually one day into a prepared opening, longer for new openings.

Roof lanterns in Bexleyheath: questions
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
Can a lantern go on an existing extension?
Yes, if the flat roof structure can be opened up and trimmed. We check joists and the roof build-up at survey.
Can you work alongside my builder in Bexleyheath?
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 Bexleyheath?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
