Skylight replacement for Holyhead: the essentials
We handle skylight replacement across Gwynedd, including Holyhead. In short: replacing tired domes and failed glass with a modern rooflight. 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. Think of skylight replacement for yellowed domes, misted glass and leaking roof windows.
Neighbouring towns include Llangefni (22 km) and Caernarfon (30 km). We offer a survey date when we reply to your enquiry.
Specification options
- Fixed to electric opening
- Dome to flat glass upgrade
- Upstand rebuild and insulation
- Roof window replacement in pitched roofs
- Misted glass unit replacement only
- Better thermal performance
- Usually done in a day
Before you order: points to check
- Upstand and roof condition decide the scope
- Enlarging the opening changes the structure and may need approval
Do you need permission in Holyhead?
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
Do I need building regulations approval to replace a rooflight?
Replacements in existing homes generally need to meet current thermal standards and may need notification or approval. We advise on the route for your job.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
How long does a replacement take?
Usually a day for a standard rooflight on a sound upstand.
Do you offer skylight replacement in Holyhead?
Yes. We carry out skylight replacement in Holyhead and across Gwynedd. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in 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.
