Loft conversion skylights in Thamesmead: what is involved?
Our loft conversion skylights service in Thamesmead 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.
Many London roofs are reached only through the house or over neighbouring property, so lifting heavy glass is planned at survey rather than on the day. In Thamesmead, as anywhere, loft conversion skylights are the usual choice for loft conversions and rooms in the roof.
Thamesmead is around 17 km from central London, and we survey and fit throughout that part of Greater London, including the SE28 district.

Planning, building control and Thamesmead
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
How many roof windows does a loft room need?
Enough to give good light — a common rule of thumb is glazing equal to roughly a tenth to a fifth of the floor area, adjusted for orientation and use. We advise at survey.
Can I add blinds later?
Yes — most manufacturers make blinds for each window size.
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.

Yes. We survey and fit loft conversion skylights in Thamesmead and across Greater London. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Thamesmead?
