What do roof lanterns in Uxbridge involve?
Thinking about roof lanterns in Uxbridge? The short answer: hipped glass lanterns that lift the ceiling of orangeries and extensions. The longer answer depends on your roof, which is why we survey before we price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. In Uxbridge, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
Uxbridge is around 25 km from central London, and we survey and fit throughout that part of Greater London, including the UB8 district.
What you can choose
- Internal and external colours
- Rectangular, square or bespoke sizes
- Opening vents with electric control
- Solar-control or self-cleaning glass
- Aluminium or uPVC systems
- Slim aluminium bars, more glass
- Light from every angle across the day
What to check first
- Needs a strong, level kerb or upstand
- Larger lanterns may need a steel or timber ring beam
Planning and building rules for Uxbridge
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
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. 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.

Roof lanterns in Uxbridge: questions
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
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.

Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
