Rooflight upstands & kerbs for Brighton: the essentials
Rooflight upstands & kerbs in Brighton means insulated kerbs built and waterproofed to suit your rooflight. We cover the BN1 district and the rest of East Sussex, with a survey before any price is fixed.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. In Brighton, as anywhere, rooflight upstands & kerbs are the usual choice for new flat-roof openings and rooflight replacements.
We cover all of Brighton and the BN1 district, and nearby Hove and Portslade.

Do you need permission in Brighton?
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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about rooflight upstands & kerbs in Brighton
Why is my rooflight cold around the edge?
Usually an uninsulated upstand. Insulating the kerb and lining the reveal fixes most cold spots.
Can an old upstand be reused?
If it is sound, square, insulated and the right size. Often it is cheaper to rebuild than adapt.
Does every rooflight need an upstand?
Flat and dome rooflights do. Pitched roof windows use flashing kits instead.
