How we approach skylight replacement in Fulham
For Fulham 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 London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. Think of skylight replacement for older extensions due a modern rooflight.
We work across Greater London, including Fulham, and in neighbouring towns such as Chelsea and Wandsworth. Access, parking and how the glass reaches the roof are all checked at the survey.
Specification options
- Roof window replacement in pitched roofs
- Fixed to electric opening
- Like-for-like size replacement
- Dome to flat glass upgrade
- Upstand rebuild and insulation
- Cures most chronic leaks
- Better thermal performance
What to check first
- Old glass and domes are disposed of responsibly
- A replacement is a chance to meet current thermal standards
Do you need permission in Fulham?
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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.

Common questions
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.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
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.
Can you work alongside my builder in Fulham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Will I need planning permission in Fulham?
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.
