Towns we list in Gwynedd & Anglesey
Fitting across Gwynedd & Anglesey means planning routes, access and lifting as well as the roof itself. Narrow lanes, shared driveways and town-centre parking restrictions all affect how a large unit is delivered and raised to roof level. We ask about these early so the quote reflects them. That approach is the same everywhere we work in Wales, from single domestic jobs to multi-unit commercial sites.
What the job includes
- Ceiling opening cut neatly and the diffuser fitted
- Dome fixed and sealed on top of the flashing
- Route through the loft checked for joists, cables and pipes
- Length and bends in the tube — We plan the shortest, straightest route we can between the roof and the ceiling.
- Tube size — We match the tube size to the room and the roof.
Rules that apply in Wales
For a Welsh home, start with where the house is. In a conservation area, National Park, AONB or World Heritage Site, a rooflight needs planning permission; outside those, permitted development usually covers one that projects 150 mm or less. Side-facing roof windows within 10.5 m of a boundary must be obscure-glazed and fixed. New openings need building regulations approval, and replacements we fit are notified with a building notice, as we are not registered with a competent person scheme. We confirm all of this for your address.
Common questions in Gwynedd & Anglesey
Do I need planning permission for a rooflight in Gwynedd & Anglesey?
Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in Wales. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.
Do you offer trade rates for builders and roofers?
We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade quote.
Can you fit a rooflight in winter or when it is raining?
Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.
