Sun tunnels & tubular skylights in Bexleyheath: what is involved?
We handle sun tunnels & tubular skylights across Greater London, including Bexleyheath. 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.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Typical uses for sun tunnels & tubular skylights include windowless hallways, landings and bathrooms.
From Bexleyheath to Welling, Bexley and Thamesmead, the same survey-first process applies: measure, specify, fix the price, then fit.
Options we can specify in Bexleyheath
- Insulated tube sections
- Pitched or flat-roof flashings
- Rigid (brighter) or flexible tubes
- Diffusers in several sizes
- Ventilation adaptor
- Daylight where no window is possible
- Small ceiling opening, quick fit
Things we check at survey
- Light output falls with tube length and bends
- Tube runs need insulation in cold lofts to limit condensation
Do you need permission in Bexleyheath?
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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.
Read the planning permission guide before you commit to a design.

Common questions
Can it work at night?
Some models include a light fitting in the diffuser.
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.
Is the survey in Bexleyheath free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Bexleyheath?
