What do roof lanterns in Ashford, Surrey involve?
Thinking about roof lanterns in Ashford, Surrey? 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Roof lanterns suit rooms that need height as well as light.

Planning, building control and Ashford, Surrey
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.

Common 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.
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.
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.
