What do conservation rooflights in Welling involve?
Our conservation rooflights service in Welling 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.
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. Think of conservation rooflights for slate and plain-tile roofs where a quiet roofline matters.
Welling is around 17 km from central London, and we survey and fit throughout that part of Greater London, including the DA16 district.
Specification options
- Manual or electric opening
- Steel or aluminium frames
- Blinds
- Flashings for slate or plain tile

Things we check at survey
- Projection above the roof line is limited — usually as flush as possible
- Conservation officers may specify size and position
Do you need permission in Welling?
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.
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. 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.

Can they open?
Yes, most are top-hung or side-hung for ventilation and cleaning, with manual or electric operation.
