Walk-on rooflights for Pimlico: the essentials
Thinking about walk-on rooflights in Pimlico? The short answer: structural glass you can stand on, set flush into terraces and floors. The longer answer depends on your roof, which is why we survey before we price.
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.
Pimlico sits about 2 km from Battersea and 2 km from Chelsea, and we cover the whole SW1 postcode district and the roads in between.

- Double or triple glazed with a structural top pane

What to check first
- Drainage around the unit needs planning so water does not pond on the glass
- Structural support and the design load must be confirmed by the manufacturer or an engineer
Planning, building control and Pimlico
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. 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.
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Is the glass slippery?
Walk-on glass has an anti-slip finish, usually a ceramic frit or etched pattern. Like any outdoor surface it needs cleaning to stay effective.
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.
Can you see through it?
Clear glass can be seen through from both sides. A privacy interlayer or patterned frit keeps the light while obscuring the view.

Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
