Sun tunnels & tubular skylights for Barnes: the essentials
Our sun tunnels & tubular skylights service in Barnes covers light pipes that bring daylight to halls and bathrooms with no window. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Sun tunnels & tubular skylights suit windowless hallways, landings and bathrooms.
Neighbouring towns include Chiswick (2 km) and Putney (3 km). We offer a survey date when we reply to your enquiry.

Planning and building rules for Barnes
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.
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.

Questions about sun tunnels & tubular skylights in Barnes
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
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 it work at night?
Some models include a light fitting in the diffuser.
Is the survey in Barnes free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Do I need to be at home for the survey in Barnes?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
