Pitched roof windows for Hounslow: the essentials
We handle pitched roof windows across Greater London, including Hounslow. In short: centre-pivot and top-hung skylights for tiled and slate 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 pitched roof windows for pitched roofs over bedrooms, stairs and bathrooms.
From Hounslow to Isleworth, Twickenham and Richmond, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for pitched roof windows in Hounslow
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
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.

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.
Centre-pivot or top-hung?
Centre-pivot windows are easy to clean and suit most rooms. Top-hung windows open out from the top for an unobstructed view and suit lower roof pitches near eye level.
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 you fit pitched roof windows in Hounslow?
Yes. We survey and fit pitched roof windows in Hounslow and across Greater London. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Hounslow?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
