Pitched roof windows for Mitcham: the essentials
For Mitcham homes and buildings we offer pitched roof windows: centre-pivot and top-hung skylights for tiled and slate roofs. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Pitched roof windows suit pitched roofs over bedrooms, stairs and bathrooms.
Neighbouring towns include Morden (2 km) and Wimbledon (3 km). We offer a survey date when we reply to your enquiry.

Consents for pitched roof windows in Mitcham
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. 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.
