What is Networkmanship?

Network VEKA is a nationwide organisation representing only the very best local uPVC window and door companies in the industry. It’s not easy to become a member, so homeowners know that when they see the Network VEKA logo, that company is committed to upholding our strict standards of workmanship, training and customer satisfaction. We call it Networkmanship for short.


  • 97% customer satisfaction

    On average, Network VEKA installers achieve around a 97% customer satisfaction rating, compared to the industry’s average of just 83%. So, when buying uPVC windows, look for a local company proudly displaying our logo.

  • A++ thermal efficiency

    The British Federation Ratings Council (BFRC) class VEKA uPVC windows and doors, as having the highest thermal efficiency. Which means our uPVC windows offer superb heat retention, saving you money on your energy bills as well as using less of the world’s resources. In fact, VEKA was the first company to ever produce an A rated window.

  • We keep things tidy

    Quality, expertise, attention to detail, that’s what you get when you choose Network VEKA. Our installers respect your home and possessions, leaving you with beautifully installed uPVC windows and nothing to clean up afterwards.

Some of our happy customers

Here are some of our reviews from our happy customers...

When installers arrived on the 27th May they were only able to install the door as the manufacturer had made errors in the windows. Due to our holiday commitments a new date could not be arranged until 17-06-2016 but commpany kept in touch with us, did not require us to pay any further funds then returned on the agreed date and installed the windows to our satisfaction.
