Sun tunnels & tubular skylights in Llangefni: what is involved?
For Llangefni 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.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Sun tunnels & tubular skylights suit small internal rooms where a full rooflight will not fit.
Jobs in Llangefni are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.

Before you order: points to check
- Gives light, not a view
- Tube runs need insulation in cold lofts to limit condensation
Consents for sun tunnels & tubular skylights in Llangefni
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
See our building regulations guide for U-values, glazing limits and self-certification.

Sun tunnels & tubular skylights in Llangefni: questions
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.
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
Can you work alongside my builder in Llangefni?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Llangefni?
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.
