How we approach sun tunnels & tubular skylights in Bentley
Sun tunnels & tubular skylights in Bentley means light pipes that bring daylight to halls and bathrooms with no window. We cover the DN5 district and the rest of South Yorkshire, with a survey before any price is fixed.
Exposed Pennine and coastal towns in Yorkshire need upstand and flashing details built for wind-driven rain. In Bentley, as anywhere, sun tunnels & tubular skylights are the usual choice for small internal rooms where a full rooflight will not fit.
Jobs in Bentley are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Rigid (brighter) or flexible tubes
- Insulated tube sections
- Integrated electric light
- Diffusers in several sizes

Do you need permission in Bentley?
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. 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. 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.
