How we approach skylight replacement in Ilkeston
Skylight replacement in Ilkeston means replacing tired domes and failed glass with a modern rooflight. We cover the DE7 district and the rest of Derbyshire, with a survey before any price is fixed.
Older terraced streets in Midlands towns often have back additions and side passages that suit a ridge rooflight or long flat rooflight. Typical uses for skylight replacement include older extensions due a modern rooflight.
Ilkeston is around 12 km from Derby, and we survey and fit throughout that part of Derbyshire, including the DE7 district.

Do you need permission in Ilkeston?
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.
