Skylight replacement for Rhondda: the essentials
Thinking about skylight replacement in Rhondda? 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.
Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen. Think of skylight replacement for yellowed domes, misted glass and leaking roof windows.
We cover all of Rhondda and the CF42 district, and nearby Tonypandy and Aberdare.
Choices for your Rhondda project
- Roof window replacement in pitched roofs
- Dome to flat glass upgrade
- Fixed to electric opening
- Upstand rebuild and insulation
- Misted glass unit replacement only
- Clearer view and more light
- Better thermal performance
Things we check at survey
- Old glass and domes are disposed of responsibly
- A replacement is a chance to meet current thermal standards
Do you need permission in Rhondda?
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.
Read the planning permission guide before you commit to a design.
