How we approach roof lanterns in Cheltenham
Thinking about roof lanterns in Cheltenham? 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.
Western coasts take wind-driven rain, so we pay close attention to upstand height and flashing laps on exposed roofs. Roof lanterns suit rooms that need height as well as light.
Cheltenham is around 12 km from Gloucester, and we survey and fit throughout that part of Gloucestershire, including the GL50 district.
What you can choose
- LED lighting in the plaster box
- Internal and external colours
- Opening vents with electric control
- Aluminium or uPVC systems
- Rectangular, square or bespoke sizes
- Slim aluminium bars, more glass
- Classic look that suits period and modern homes
Things we check at survey
- Larger lanterns may need a steel or timber ring beam
- Some designs project above the roof enough to affect planning on certain houses
Consents for roof lanterns in Cheltenham
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.
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. 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.

Questions about roof lanterns in Cheltenham
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.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Can a lantern go on an existing extension?
Yes, if the flat roof structure can be opened up and trimmed. We check joists and the roof build-up at survey.
Can you work alongside my builder in Cheltenham?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Do you fit roof lanterns in Cheltenham?
Yes. We survey and fit roof lanterns in Cheltenham and across Gloucestershire. Send your postcode and we will offer a survey date when we reply.
