Sun tunnels & tubular skylights for Borehamwood: the essentials
Thinking about sun tunnels & tubular skylights in Borehamwood? 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.
Larger gardens in much of the South East mean deeper rear extensions, and deeper rooms need light from above rather than only from the doors. In Borehamwood, as anywhere, sun tunnels & tubular skylights are the usual choice for windowless hallways, landings and bathrooms.
Borehamwood sits about 5 km from Barnet and 6 km from Bushey, and we cover the whole WD6 postcode district and the roads in between.

Consents for sun tunnels & tubular skylights in Borehamwood
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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Can it work at night?
Some models include a light fitting in the diffuser.
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.
Can you work alongside my builder in Borehamwood?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Borehamwood?
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.
