Sun tunnels & tubular skylights in Powys: the essentials
Across Powys, 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.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen.

Planning and building rules in Wales
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
Welsh Building Regulations expect new or replacement rooflights to reach 2.2 W/m²K and roof windows 1.4 W/m²K or a Band B rating. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Common 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 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.
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
Will I need planning permission in Powys?
Planning rules in Wales are tighter than in England for rooflights: Class C rights do not apply in conservation areas, National Parks or AONBs, so a rooflight there needs planning permission.
