Conservation rooflights for Sunbury-on-Thames: the essentials
Thinking about conservation rooflights in Sunbury-on-Thames? The short answer: slim, low-profile steel-look rooflights for period and listed roofs. The longer answer depends on your roof, which is why we survey before we price.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Think of conservation rooflights for period, listed and conservation-area roofs.
We work across Surrey, including Sunbury-on-Thames, and in neighbouring towns such as Walton-on-Thames and Hampton. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Sunbury-on-Thames
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.
