Roof lanterns in Canterbury: what is involved?
Roof lanterns in Canterbury means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the CT1 district and the rest of Kent, with a survey before any price is fixed.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. In Canterbury, as anywhere, roof lanterns are the usual choice for orangeries, kitchen-diners and single-storey extensions.
From Canterbury to Whitstable, Herne Bay and Faversham, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Internal and external colours
- LED lighting in the plaster box
- Rectangular, square or bespoke sizes
- Aluminium or uPVC systems
- Solar-control or self-cleaning glass
- Can include opening vents
- Light from every angle across the day
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
Consents for roof lanterns in Canterbury
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. 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.

Roof lanterns in Canterbury: 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.
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.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
