How we approach sun tunnels & tubular skylights in Llantwit Major
For Llantwit Major homes and buildings we offer sun tunnels & tubular skylights: light pipes that bring daylight to halls and bathrooms with no window. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. In Llantwit Major, as anywhere, sun tunnels & tubular skylights are the usual choice for windowless hallways, landings and bathrooms.
From Llantwit Major to Cowbridge, Bridgend and Barry, the same survey-first process applies: measure, specify, fix the price, then fit.

Consents for sun tunnels & tubular skylights in Llantwit Major
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. 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.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. 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 Llantwit Major
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.
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 you work alongside my builder in Llantwit Major?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do I need to be at home for the survey in Llantwit Major?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
