How we approach roof lanterns in Blyth
We handle roof lanterns across Northumberland, including Blyth. 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.
Many North East homes have loft rooms that benefit from larger roof windows with blackout blinds. Roof lanterns suit orangeries, kitchen-diners and single-storey extensions.
Blyth is the main town we list in Northumberland; we also cover nearby Ashington and Cramlington.
What you can choose
- Solar-control or self-cleaning glass

- Classic look that suits period and modern homes
Things we check at survey

Planning, building control and Blyth
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. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
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.
Read the planning permission guide before you commit to a design.

Roof lanterns in Blyth: questions
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 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.
Do you fit roof lanterns in Blyth?
Yes. We survey and fit roof lanterns in Blyth and across Northumberland. Send your postcode and we will offer a survey date when we reply.
Will I need planning permission in Blyth?
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.
