Skylight installation in Thamesmead: what is involved?
Our skylight installation service in Thamesmead covers survey, supply and fit — new openings, extensions and fit-only work. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
London homes often run deep from front to back, so the middle of the ground floor is the darkest space — exactly where an overhead rooflight earns its keep. Think of skylight installation for new extensions, new openings and fit-only jobs.
Neighbouring towns include Barking (4 km) and Welling (5 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Thamesmead
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.
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.
Read the planning permission guide before you commit to a design.

Is the survey free?
Yes, for new installations. Repair visits are charged.

Yes. We carry out skylight installation in Thamesmead and across Greater London. Send your postcode and we will offer a survey date when we reply.
Can you work alongside my builder in Thamesmead?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
