What do roof lanterns in Bexley involve?
We handle roof lanterns across Greater London, including Bexley. In short: hipped glass lanterns that lift the ceiling of orangeries and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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. Think of roof lanterns for rooms that need height as well as light.
Jobs in Bexley are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Options we can specify in Bexley
- Internal and external colours
- Aluminium or uPVC systems
- Rectangular, square or bespoke sizes
- LED lighting in the plaster box
- Solar-control or self-cleaning glass
- Light from every angle across the day
- Classic look that suits period and modern homes
Before you order: points to check
- Some designs project above the roof enough to affect planning on certain houses
- Needs a strong, level kerb or upstand
Planning, building control and Bexley
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.
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. 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.

Common questions
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
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.
Is the survey in Bexley free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Bexley?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
