How we approach sun tunnels & tubular skylights in Biggleswade
Thinking about sun tunnels & tubular skylights in Biggleswade? 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. Sun tunnels & tubular skylights suit small internal rooms where a full rooflight will not fit.
Biggleswade sits about 5 km from Sandy and 12 km from Letchworth Garden City, and we cover the whole SG18 postcode district and the roads in between.

Consents for sun tunnels & tubular skylights in Biggleswade
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. 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.

Sun tunnels & tubular skylights in Biggleswade: questions
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
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.
Will I need planning permission in Biggleswade?
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.
Do I need to be at home for the survey in Biggleswade?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
