Do you need permission in Llanelli?
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
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.

Questions about sun tunnels & tubular skylights in Llanelli
How much light does a sun tunnel give?
A good rigid tunnel on a bright day lights a hallway well. Output depends on tube diameter, length and the number of bends.
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
Will I need planning permission in Llanelli?
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.
How do I book a survey in Llanelli?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
