Skylight replacement for Surbiton: the essentials
Skylight replacement in Surbiton means replacing tired domes and failed glass with a modern rooflight. We cover the KT5 district and the rest of Greater London, with a survey before any price is fixed.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Skylight replacement suits yellowed domes, misted glass and leaking roof windows.
From Surbiton to New Malden, Kingston upon Thames and Esher, the same survey-first process applies: measure, specify, fix the price, then fit.
What you can choose
- Misted glass unit replacement only
- Dome to flat glass upgrade
- Upstand rebuild and insulation
- Like-for-like size replacement
- Roof window replacement in pitched roofs
- Cures most chronic leaks
- Often reuses the existing opening
Things we check at survey
- Old glass and domes are disposed of responsibly
- Enlarging the opening changes the structure and may need approval
Planning, building control and Surbiton
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. 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.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. 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.
Read the planning permission guide before you commit to a design.

Common 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.
Can I go bigger when replacing?
Possibly. Enlarging the opening means trimming joists, so we check the structure first.
Will it mess up my ceiling?
We protect the room and make good the reveal. Minor decoration may be needed afterwards.
Can you work alongside my builder in Surbiton?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Surbiton?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
