Sun tunnels & tubular skylights in Chelsea: what is involved?
Thinking about sun tunnels & tubular skylights in Chelsea? The short answer: light pipes that bring daylight to halls and bathrooms with no window. The longer answer depends on your roof, which is why we survey before we price.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Typical uses for sun tunnels & tubular skylights include small internal rooms where a full rooflight will not fit.
Chelsea is around 4 km from central London, and we survey and fit throughout that part of Greater London, including the SW10 district.
What you can choose
- Insulated tube sections
- Diffusers in several sizes
- Integrated electric light
- Rigid (brighter) or flexible tubes
- Pitched or flat-roof flashings
- Small ceiling opening, quick fit
- Works on pitched and flat roofs
Before you order: points to check
- Gives light, not a view
- Tube runs need insulation in cold lofts to limit condensation
Consents for sun tunnels & tubular skylights in Chelsea
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. 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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
How much light does a sun tunnel give?
A good rigid tunnel on a bright day lights a hallway well. Output depends on tube diameter, length and the number of bends.
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
Will I need planning permission in Chelsea?
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.
Is the survey in Chelsea free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
