How we approach skylight replacement in Whitstable
Skylight replacement in Whitstable means replacing tired domes and failed glass with a modern rooflight. We cover the CT5 district and the rest of Kent, with a survey before any price is fixed.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. In Whitstable, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
Whitstable is around 37 km from Maidstone, and we survey and fit throughout that part of Kent, including the CT5 district.
What you can choose
- Upstand rebuild and insulation
- Dome to flat glass upgrade
- Fixed to electric opening
- Misted glass unit replacement only
- Roof window replacement in pitched roofs
- Option to add opening and rain sensor
- Better thermal performance
Before you order: points to check
- Old glass and domes are disposed of responsibly
- Enlarging the opening changes the structure and may need approval
Planning, building control and Whitstable
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.
See our building regulations guide for U-values, glazing limits and self-certification.
