Loft conversion skylights in Putney: what is involved?
Our loft conversion skylights service in Putney covers roof windows planned for loft rooms — light, headroom and escape. 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. Think of loft conversion skylights for attic bedrooms, offices and en-suites.
Putney is around 8 km from central London, and we survey and fit throughout that part of Greater London, including the SW15 district.

What to check first

Do you need permission in Putney?
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.

Questions about loft conversion skylights in Putney
Will the loft be cold near the windows?
Correctly fitted insulation collars and linings keep the window surround warm and reduce condensation.
Top-hung or centre-pivot in a loft?
Top-hung gives a clearer view and often suits escape use; centre-pivot is easier to clean and suits higher positions.
Can I add blinds later?
Yes — most manufacturers make blinds for each window size.
Do I need to be at home for the survey in Putney?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Putney?
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.
