Conservation rooflights in Mitcham: what is involved?
Our conservation rooflights service in Mitcham covers slim, low-profile steel-look rooflights for period and listed roofs. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Think of conservation rooflights for period, listed and conservation-area roofs.
Mitcham is around 12 km from central London, and we survey and fit throughout that part of Greater London, including the CR4 district.
Options we can specify in Mitcham
- Central vertical glazing bar
- Manual or electric opening

Before you order: points to check
- Conservation officers may specify size and position
- Projection above the roof line is limited — usually as flush as possible
Planning and building rules for Mitcham
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.
