What does skylight replacement in Crowborough involve?
We handle skylight replacement across East Sussex, including Crowborough. 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.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Crowborough, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
We work across East Sussex, including Crowborough, and in neighbouring towns such as Tunbridge Wells and East Grinstead. Access, parking and how the glass reaches the roof are all checked at the survey.
Options we can specify in Crowborough
- Misted glass unit replacement only
- Upstand rebuild and insulation
- Fixed to electric opening

What to check first
- Enlarging the opening changes the structure and may need approval
- Upstand and roof condition decide the scope
Do you need permission in Crowborough?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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.

Skylight replacement in Crowborough: questions
Can you replace only the misted glass?
Sometimes, if the frame is sound and the maker supplies replacement units. Often a complete new rooflight costs little more and performs better.
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.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Will I need planning permission in Crowborough?
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.
Do I need to be at home for the survey in Crowborough?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
