What do sun tunnels & tubular skylights in Croydon involve?
We handle sun tunnels & tubular skylights across Greater London, including Croydon. 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.
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 windowless hallways, landings and bathrooms.
From Croydon to South Croydon, Wallington and Carshalton, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning and building rules for Croydon
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. 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.

- Agree the quote. You approve the specification and price before anything is ordered.
- Installation day. Usually one day into a prepared opening, longer for new openings.

Common questions
Can it work at night?
Some models include a light fitting in the diffuser.
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.
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
Is the survey in Croydon free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Can you work alongside my builder in Croydon?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
