Sun tunnels & tubular skylights for Thamesmead: the essentials
For Thamesmead homes and buildings we offer sun tunnels & tubular skylights: light pipes that bring daylight to halls and bathrooms with no window. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
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. Sun tunnels & tubular skylights suit small internal rooms where a full rooflight will not fit.
Thamesmead is around 17 km from central London, and we survey and fit throughout that part of Greater London, including the SE28 district.
What you can choose
- Diffusers in several sizes
- Rigid (brighter) or flexible tubes
- Ventilation adaptor
- Integrated electric light
- Insulated tube sections
- Small ceiling opening, quick fit
- Rigid or flexible tubes for awkward lofts
Before you order: points to check
- Tube runs need insulation in cold lofts to limit condensation
- Not a substitute for a habitable-room window
Planning, building control and Thamesmead
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. 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.
Read the planning permission guide before you commit to a design.

Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
