What does skylight installation in Holyhead involve?
For Holyhead homes and buildings we offer skylight installation: survey, supply and fit — new openings, extensions and fit-only work. 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. Typical uses for skylight installation include new extensions, new openings and fit-only jobs.
Holyhead is around 34 km from Bangor, Gwynedd, and we survey and fit throughout that part of Gwynedd, including the LL65 district.
What you can choose
- Supply and fit
- Electrics coordination
- Internal plaster reveal
- Upstands and flashings
- Fit only (customer-supplied units)
- Fixed price in writing before work
- New openings in existing roofs
What to check first
- Building Regulations approval (a building warrant in Scotland) may be needed
- Structural changes may need an engineer's check
Do you need permission in Holyhead?
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about skylight installation in Holyhead
Do I need a structural engineer?
For new openings that cut joists or rafters, a structural check is sensible and building control may ask for calculations.
How long does installation take?
Fitting into a prepared upstand takes about a day. A new opening in an existing roof, including making good, often takes two to three days.
Who handles building control?
We tell you which route applies — building control approval, a building warrant in Scotland, or in England and Wales self-certification by a registered competent person — and supply the product data.
Do I need to be at home for the survey in Holyhead?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
