What does skylight replacement in Colwyn Bay involve?
Thinking about skylight replacement in Colwyn Bay? The short answer: replacing tired domes and failed glass with a modern rooflight. The longer answer depends on your roof, which is why we survey before we price.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. In Colwyn Bay, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
Jobs in Colwyn Bay 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.
What you can choose
- Fixed to electric opening
- Like-for-like size replacement
- Upstand rebuild and insulation
- Dome to flat glass upgrade
- Misted glass unit replacement only
- Usually done in a day
- Better thermal performance
Things we check at survey
- A replacement is a chance to meet current thermal standards
- Old glass and domes are disposed of responsibly
Do you need permission in Colwyn Bay?
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. Listed buildings need listed building consent from the council, and flats have no householder permitted development rights.
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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.
