How we approach sun tunnels & tubular skylights in Redhill
We handle sun tunnels & tubular skylights across Surrey, including Redhill. 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 South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Typical uses for sun tunnels & tubular skylights include small internal rooms where a full rooflight will not fit.
From Redhill to Reigate, Horley and Caterham, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Diffusers in several sizes
- Rigid (brighter) or flexible tubes
- Integrated electric light
- Ventilation adaptor
- Insulated tube sections
- Daylight where no window is possible
- Optional ventilation or lighting kit on some models
What to check first
- Not a substitute for a habitable-room window
- Light output falls with tube length and bends
Planning, building control and Redhill
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. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Sun tunnels & tubular skylights in Redhill: 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.
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
Do I need to be at home for the survey in Redhill?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Redhill free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
