Sun tunnels & tubular skylights for Coulsdon: the essentials
Thinking about sun tunnels & tubular skylights in Coulsdon? 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.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Think of sun tunnels & tubular skylights for small internal rooms where a full rooflight will not fit.
Neighbouring towns include Purley (3 km) and Banstead (5 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Coulsdon
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.

Sun tunnels & tubular skylights in Coulsdon: questions
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.
Can it work at night?
Some models include a light fitting in the diffuser.
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 Coulsdon?
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.
Do I need to be at home for the survey in Coulsdon?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
