Skylight replacement for Enfield: the essentials
We handle skylight replacement across Greater London, including Enfield. 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.
Party walls are a fact of life in London terraces, and rooflights close to a shared wall need detailing that keeps the neighbour's side dry too. Skylight replacement suits older extensions due a modern rooflight.
Jobs in Enfield are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
Specification options
- Like-for-like size replacement
- Roof window replacement in pitched roofs
- Fixed to electric opening
- Dome to flat glass upgrade
- Misted glass unit replacement only
- Option to add opening and rain sensor
- Better thermal performance
Before you order: points to check
- Upstand and roof condition decide the scope
- A replacement is a chance to meet current thermal standards
Do you need permission in Enfield?
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Our planning guide covers each nation in more detail.

Skylight replacement in Enfield: questions
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
What do you do with the old unit?
We remove it from site and recycle what can be recycled.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Do I need to be at home for the survey in Enfield?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Enfield?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
