What do roof lanterns in Milton Keynes involve?
We handle roof lanterns across Buckinghamshire, including Milton Keynes. 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.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Milton Keynes, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
We cover all of Milton Keynes and the MK9 district, and nearby Bletchley and Leighton Buzzard.
What you can choose
- Aluminium or uPVC systems
- Opening vents with electric control
- LED lighting in the plaster box
- Rectangular, square or bespoke sizes
- Solar-control or self-cleaning glass
- Classic look that suits period and modern homes
- Can include opening vents
Things we check at survey
- Larger lanterns may need a steel or timber ring beam
- Some designs project above the roof enough to affect planning on certain houses
Consents for roof lanterns in Milton Keynes
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.
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. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Questions about roof lanterns in Milton Keynes
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.
Do I need to be at home for the survey in Milton Keynes?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Is the survey in Milton Keynes free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
