Conservation rooflights for Hounslow: the essentials
We handle conservation rooflights across Greater London, including Hounslow. In short: slim, low-profile steel-look rooflights for period and listed roofs. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
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. Think of conservation rooflights for period, listed and conservation-area roofs.
Neighbouring towns include Isleworth (1 km) and Twickenham (3 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Hounslow
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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.
Read the planning permission guide before you commit to a design.
