What do walk-on rooflights in Bromley involve?
Walk-on rooflights in Bromley means structural glass you can stand on, set flush into terraces and floors. We cover the BR1 district and the rest of Greater London, with a survey before any price is fixed.
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. Walk-on rooflights suit roof terraces, balconies and floors above basements.
We work across Greater London, including Bromley, and in neighbouring towns such as Beckenham and Catford. Access, parking and how the glass reaches the roof are all checked at the survey.

Before you order: points to check
- Structural support and the design load must be confirmed by the manufacturer or an engineer
- Drainage around the unit needs planning so water does not pond on the glass
Do you need permission in Bromley?
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Walk-on rooflights in Bromley: questions
Can it be used inside the house?
Yes. Internal walk-on panels pass light from an upper floor or ground floor to a basement below.
Will it sit flush with my paving?
Yes — the unit is set on its own upstand so the glass finishes level with the surrounding paving or decking.
Does it need a structural engineer?
Often, yes. Where the unit sits on new or altered structure, an engineer confirms the support and the manufacturer confirms the glass.
Can you work alongside my builder in Bromley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
