Roof lanterns in Dunstable: what is involved?
Roof lanterns in Dunstable means hipped glass lanterns that lift the ceiling of orangeries and extensions. We cover the LU6 district and the rest of Bedfordshire, with a survey before any price is fixed.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
Dunstable is around 7 km from Luton, and we survey and fit throughout that part of Bedfordshire, including the LU6 district.

Consents for roof lanterns in Dunstable
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. 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.
Building Regulations Approved Document L sets a limiting U-value of 2.2 W/m²K for new or replacement rooflights in existing homes, measured in the horizontal plane; roof windows need 1.4 W/m²K or a Band B energy rating. Replacing a rooflight or roof window can be self-certified by an installer registered with an authorised competent person scheme; otherwise building control approval is needed.

Roof lanterns in Dunstable: questions
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
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.
Can you work alongside my builder in Dunstable?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
