Roof lanterns in Norwich: what is involved?
We handle roof lanterns across Norfolk, including Norwich. 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.
Barn conversions and timber-framed homes across the East often call for conservation rooflights or bespoke glass. In Norwich, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
Norwich is the main town we list in Norfolk; we also cover nearby Wymondham and Great Yarmouth.
What you can choose
- LED lighting in the plaster box
- Rectangular, square or bespoke sizes
- Solar-control or self-cleaning glass
- Opening vents with electric control
- Internal and external colours
- Light from every angle across the day
- Classic look that suits period and modern homes
Things we check at survey
- Plaster-box depth affects how the lantern looks from below
- Larger lanterns may need a steel or timber ring beam
Planning, building control and Norwich
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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
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.
Do you fit roof lanterns in Norwich?
Yes. We survey and fit roof lanterns in Norwich and across Norfolk. Send your postcode and we will offer a survey date when we reply.
Do I need to be at home for the survey in Norwich?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
