What does skylight installation in Twickenham involve?
Skylight installation in Twickenham means survey, supply and fit — new openings, extensions and fit-only work. We cover the TW1 district and the rest of Greater London, with a survey before any price is fixed.
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. Skylight installation suits builders' projects and retrofits into finished roofs.
We work across Greater London, including Twickenham, and in neighbouring towns such as Richmond and Kingston upon Thames. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Twickenham
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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. 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.

Questions about skylight installation in Twickenham
Is the survey free?
Yes, for new installations. Repair visits are charged.
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
Do you work with builders?
Yes — on new extensions we fit to the builder's programme once the upstand or roof is ready.
Do I need to be at home for the survey in Twickenham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Twickenham?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
