Skylights and rooflights across Powys
SkylightCompany.uk covers the whole of Powys — homes, extensions, schools and commercial roofs — with a free survey for new installations.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere.
Chapels, barns and farm buildings converted across Wales often need bespoke or conservation-style glass.

Planning and building rules in Wales
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. 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. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

Common questions
Do you cover all of Powys?
Yes. We survey and fit across Powys, including Brecon, Llandrindod Wells and Machynlleth. Remote and island addresses are by arrangement.
Do I need planning permission for a rooflight in Powys?
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.
How quickly can you fit?
Manufacturers typically quote two to four weeks for standard rooflights; bespoke, structural and motorised units take longer. Your quote states the lead time.
How do I get a price?
Use the guide-price tool for an instant range, or send the form with your postcode and a photo for a fixed quote after survey.
Fixed or opening?
Opening units suit kitchens, bathrooms and bedrooms; fixed units are simpler and cheaper where the room already ventilates well.
