What do conservation rooflights in Cowbridge involve?
Our conservation rooflights service in Cowbridge covers slim, low-profile steel-look rooflights for period and listed roofs. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Welsh planning rules exclude rooflights from permitted development in conservation areas and National Parks, so we check the designation before quoting. Conservation rooflights suit period, listed and conservation-area roofs.
Neighbouring towns include Llantwit Major (6 km) and Bridgend (11 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Cowbridge
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
Are conservation rooflights double glazed?
Most modern ones are, with slim units behind the traditional frame.
Do I need consent for a conservation rooflight?
On a listed building you need listed building consent. In a conservation area, check with the council — many areas have Article 4 directions affecting roof alterations.
Can they open?
Yes, most are top-hung or side-hung for ventilation and cleaning, with manual or electric operation.
Do I need to be at home for the survey in Cowbridge?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Cowbridge?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
