What are sun tunnels & tubular skylights?
Across West Sussex, our sun tunnels & tubular skylights work covers light pipes that bring daylight to halls and bathrooms with no window. Survey first, fixed price second, fitting third.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens.

Planning and building rules in England
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. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
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.
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
Do I need to be at home for the survey in West Sussex?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
