How we approach rooflight upstands & kerbs in Kensington
Rooflight upstands & kerbs in Kensington means insulated kerbs built and waterproofed to suit your rooflight. We cover the W8 district and the rest of Greater London, with a survey before any price is fixed.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of rooflight upstands & kerbs for new flat-roof openings and rooflight replacements.

Consents for rooflight upstands & kerbs in Kensington
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.

Common questions
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
What roof coverings do you work with?
Single-ply, EPDM, felt, GRP and liquid-applied systems — or we coordinate with your roofer.
Can I build the upstand myself?
Your builder can, to our drawing. We check it before the rooflight is fitted, because the unit must sit square and level.
Is the survey in Kensington free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Kensington?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
