How we approach skylight replacement in Bath
For Bath homes and buildings we offer skylight replacement: replacing tired domes and failed glass with a modern rooflight. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Many South West towns mix Georgian and Victorian terraces with modern estates, so the right product differs street by street. Think of skylight replacement for older extensions due a modern rooflight.
We cover all of Bath and the BA1 district, and nearby Trowbridge and Kingswood.
Specification options
- Roof window replacement in pitched roofs
- Upstand rebuild and insulation
- Like-for-like size replacement
- Misted glass unit replacement only
- Fixed to electric opening
- Often reuses the existing opening
- Usually done in a day
Before you order: points to check
- Enlarging the opening changes the structure and may need approval
- Old glass and domes are disposed of responsibly
Consents for skylight replacement in Bath
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.
Read the planning permission guide before you commit to a design.
