How we approach pitched roof windows in Coulsdon
Thinking about pitched roof windows in Coulsdon? The short answer: centre-pivot and top-hung skylights for tiled and slate roofs. The longer answer depends on your roof, which is why we survey before we price.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Pitched roof windows suit lofts, attic rooms, landings and vaulted ceilings.
Neighbouring towns include Purley (3 km) and Banstead (5 km). We offer a survey date when we reply to your enquiry.

Consents for pitched roof windows in Coulsdon
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Will it need building regulations approval?
Fitting a new roof window usually involves cutting rafters and changing the thermal envelope, so building control approval (or, in England and Wales, a competent-person route) is normally needed. We tell you which applies.
Can you replace an old roof window?
Yes — replacement into the same opening is usually quicker than a new install, often a few hours per window.
Do I need planning permission for a roof window?
Often not, under householder permitted development, provided it does not project too far above the roof plane and conditions are met. Listed buildings, flats and some conservation areas are different. Our planning guide covers each nation.
