How we approach roof lanterns in Luton
We handle roof lanterns across Bedfordshire, including Luton. In short: hipped glass lanterns that lift the ceiling of orangeries and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Many South East homes have been extended more than once, and an old dome over an earlier extension is often due for replacement. Roof lanterns suit rooms that need height as well as light.
Luton is the main town we list in Bedfordshire; we also cover nearby Dunstable and Harpenden.
What you can choose
- Solar-control or self-cleaning glass
- LED lighting in the plaster box
- Aluminium or uPVC systems
- Internal and external colours
- Rectangular, square or bespoke sizes
- Adds visual height to a single-storey room
- Light from every angle across the day
Before you order: points to check
- Plaster-box depth affects how the lantern looks from below
- Some designs project above the roof enough to affect planning on certain houses
Consents for roof lanterns in Luton
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. 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.
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.

Roof lanterns in Luton: questions
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.
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.
Do I need to be at home for the survey in Luton?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
How do I book a survey in Luton?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
