Sun tunnels & tubular skylights in Barnet: what is involved?
We handle sun tunnels & tubular skylights across Greater London, including Barnet. In short: light pipes that bring daylight to halls and bathrooms with no window. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Victorian and Edwardian terraces with narrow side returns are typical of much of London, and a glass roof or long flat rooflight is the usual way to keep the back rooms bright once the return is built over. Sun tunnels & tubular skylights suit windowless hallways, landings and bathrooms.
Neighbouring towns include Potters Bar (5 km) and Borehamwood (5 km). We offer a survey date when we reply to your enquiry.
What you can choose
- Diffusers in several sizes
- Pitched or flat-roof flashings
- Insulated tube sections
- Ventilation adaptor
- Rigid (brighter) or flexible tubes
- Low maintenance
- Small ceiling opening, quick fit
Before you order: points to check
- Gives light, not a view
- Light output falls with tube length and bends
Planning and building rules for Barnet
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.
