Sliding rooflights in Holyhead: what is involved?
We handle sliding rooflights across Gwynedd, including Holyhead. In short: box rooflights whose glass lid slides back for walk-out roof access. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass. Typical uses for sliding rooflights include walk-out access where a hatch would feel cramped.
From Holyhead to Llangefni, Caernarfon and Bangor, Gwynedd, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Anthracite, black or RAL frames
- Box (glazed sides) or flat sliding lid
- Electric drive with safety edge
- Rain sensor
- Double or triple glazing
- Electric operation with safety stops
- Glazed box sides keep the headroom open
Things we check at survey
- Electric units need a dedicated supply and commissioning
- Needs space on the roof for the lid to slide clear
Planning, building control and Holyhead
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Common questions
Is a sliding rooflight better than an access hatch?
For daily use, usually yes — you walk out under open sky instead of climbing through a hinged hatch. A hatch costs less and suits occasional access.
Does it need planning permission?
A box unit that projects above the roof plane can need planning permission, especially on the front of a house or in a conservation area. We check before you order.
What if it is raining?
Fitted with a rain sensor, an electric unit closes automatically. Most also have a manual override for power cuts.
Can you work alongside my builder in Holyhead?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Holyhead?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
