What do sun tunnels & tubular skylights in Caterham involve?
Thinking about sun tunnels & tubular skylights in Caterham? The short answer: light pipes that bring daylight to halls and bathrooms with no window. The longer answer depends on your roof, which is why we survey before we price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Think of sun tunnels & tubular skylights for windowless hallways, landings and bathrooms.
We work across Surrey, including Caterham, and in neighbouring towns such as Coulsdon and Purley. Access, parking and how the glass reaches the roof are all checked at the survey.

Consents for sun tunnels & tubular skylights in Caterham
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.
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.

Sun tunnels & tubular skylights in Caterham: questions
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
Do sun tunnels need planning permission?
Usually not on a house, provided the dome does not project too far and the property is not listed. Check if you live in a conservation area or a flat.
Do I need to be at home for the survey in Caterham?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
