Energy Efficient

Energy Efficient windows and doors by Discount UPVC Windows Cardiff

 With energy prices constantly on the rise, we know how important it is to help reduce heat loss to the absolute minimum.

That’s why we only use products that offer the best energy efficient rating possible, helping to keep your home warm for longer and for less cost.

Established Company


Discount uPVC Windows was established in 1990 to address a gap in the marketplace for a local, reliable and professional provider of double glazed windows, doors and conservatories to local customers.

Since that time, due to the level of referrals and recommendations from existing customers, it has grown to be a key provider throughout South Wales and the Valleys, with the majority of its customer base both in and around Cardiff.
