Skylight repairs & leak fixes in Thornton-Cleveleys: what is involved?
Thinking about skylight repairs & leak fixes in Thornton-Cleveleys? The short answer: leak tracing, resealing, actuator repairs and glass replacement. The longer answer depends on your roof, which is why we survey before we price.

Planning and building rules for Thornton-Cleveleys
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.
