What does skylight replacement in Wandsworth involve?
Our skylight replacement service in Wandsworth covers replacing tired domes and failed glass with a modern rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
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 yellowed domes, misted glass and leaking roof windows.
Wandsworth sits about 1 km from Battersea and 2 km from Chelsea, and we cover the whole SW18 postcode district and the roads in between.
What you can choose
- Fixed to electric opening
- Upstand rebuild and insulation
- Roof window replacement in pitched roofs
- Like-for-like size replacement
- Dome to flat glass upgrade
- Usually done in a day
- Clearer view and more light
Things we check at survey
- Enlarging the opening changes the structure and may need approval
- Upstand and roof condition decide the scope
Planning, building control and Wandsworth
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. 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.
