Conservation rooflights in Westbury-on-Trym: what is involved?
Thinking about conservation rooflights in Westbury-on-Trym? The short answer: slim, low-profile steel-look rooflights for period and listed roofs. The longer answer depends on your roof, which is why we survey before we price.

Do you need permission in Westbury-on-Trym?
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. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
