Roof lanterns for Brecon: the essentials
Our roof lanterns service in Brecon covers hipped glass lanterns that lift the ceiling of orangeries and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Think of roof lanterns for orangeries, kitchen-diners and single-storey extensions.
Brecon is around 64 km from Newtown, and we survey and fit throughout that part of Powys, including the LD3 district.
What you can choose
- Aluminium or uPVC systems
- Solar-control or self-cleaning glass
- LED lighting in the plaster box
- Internal and external colours
- Rectangular, square or bespoke sizes
- Adds visual height to a single-storey room
- Classic look that suits period and modern homes
Before you order: points to check
- Some designs project above the roof enough to affect planning on certain houses
- Larger lanterns may need a steel or timber ring beam
Planning and building rules for Brecon
Welsh householder permitted development (Class C) allows rooflights that project no more than 15 cm and sit no higher than the existing roof — but not in conservation areas, National Parks, AONBs or World Heritage Sites. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
Approved Document L in Wales (2022 edition) sets 2.2 W/m²K for rooflights, measured horizontally, and 1.4 W/m²K or Band B for roof windows in existing homes. A revised Welsh Approved Document L takes effect on 4 March 2027; rooflights in new dwellings stay at 2.2 W/m²K.

Common 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 they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
Is the survey in Brecon free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
Will I need planning permission in Brecon?
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed.
