Bespoke & shaped rooflights in Welling: what is involved?
Bespoke & shaped rooflights in Welling means triangular, angled, curved and multi-pane rooflights made to measure. We cover the DA16 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. Bespoke & shaped rooflights suit angled ceilings, corners and architect-designed extensions.
From Welling to Bexleyheath, Bexley and Sidcup, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Welling
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.
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.
