What do roof lanterns in Northolt involve?
Our roof lanterns service in Northolt covers hipped glass lanterns that lift the ceiling of orangeries and extensions. 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. Roof lanterns suit rooms that need height as well as light.
Jobs in Northolt are planned around access: whether the roof can be reached from the garden, whether a hoist or crane is needed, and where we can park. We check this when we measure.
What you can choose
- Opening vents with electric control
- Solar-control or self-cleaning glass
- Internal and external colours
- Aluminium or uPVC systems
- LED lighting in the plaster box
- Adds visual height to a single-storey room
- Slim aluminium bars, more glass
What to check first
- Needs a strong, level kerb or upstand
- Plaster-box depth affects how the lantern looks from below
Planning, building control and Northolt
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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. 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.

Roof lanterns in Northolt: questions
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
Will I need planning permission in Northolt?
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.
Is the survey in Northolt free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
