Sun tunnels & tubular skylights in Monmouth: what is involved?
We handle sun tunnels & tubular skylights across Gwent, including Monmouth. In short: light pipes that bring daylight to halls and bathrooms with no window. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Slate roofs, stone cottages and terraced valleys are typical across Wales, and slim rooflights that sit low in the slates suit them best. Typical uses for sun tunnels & tubular skylights include windowless hallways, landings and bathrooms.
Jobs in Monmouth 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.
Specification options
- Integrated electric light
- Ventilation adaptor
- Rigid (brighter) or flexible tubes
- Diffusers in several sizes
- Insulated tube sections
- Works on pitched and flat roofs
- Optional ventilation or lighting kit on some models
What to check first
- Tube runs need insulation in cold lofts to limit condensation
- Light output falls with tube length and bends
Do you need permission in Monmouth?
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.
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.
Read the planning permission guide before you commit to a design.

Common questions
Will it get condensation?
Insulating the tube where it passes through a cold loft prevents most condensation.
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 work at night?
Some models include a light fitting in the diffuser.
Will I need planning permission in Monmouth?
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.
Can you work alongside my builder in Monmouth?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
