What do loft conversion skylights in Bromley involve?
Loft conversion skylights in Bromley means roof windows planned for loft rooms — light, headroom and escape. We cover the BR1 district and the rest of Greater London, with a survey before any price is fixed.
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 Bromley, as anywhere, loft conversion skylights are the usual choice for loft conversions and rooms in the roof.
We work across Greater London, including Bromley, and in neighbouring towns such as Beckenham and Catford. Access, parking and how the glass reaches the roof are all checked at the survey.

Planning, building control and Bromley
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. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
Read the planning permission guide before you commit to a design.

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.
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.
Do loft roof windows need to be escape windows?
Some loft rooms need an escape window, depending on the layout and the fire strategy for the conversion. Building control confirms the requirement.
Is the survey in Bromley free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
How do I book a survey in Bromley?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
