Roof lanterns for Penrith: the essentials
Thinking about roof lanterns in Penrith? 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.
The North West gets more rain than most of England, so upstand height, membrane detailing and rain sensors on opening units are not optional extras. Roof lanterns suit rooms that need height as well as light.
Penrith is around 28 km from Carlisle, and we survey and fit throughout that part of Cumbria, including the CA11 district.
Options we can specify in Penrith
- LED lighting in the plaster box
- Rectangular, square or bespoke sizes
- Aluminium or uPVC systems
- Internal and external colours
- Solar-control or self-cleaning glass
- Classic look that suits period and modern homes
- Adds visual height to a single-storey room
Before you order: points to check
- Some designs project above the roof enough to affect planning on certain houses
- Larger lanterns may need a steel or timber ring beam
Planning, building control and Penrith
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common questions
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.
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 you work alongside my builder in Penrith?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
How do I book a survey in Penrith?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
