What is Networkmanship?

Independent Network 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 Independent Network 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, Independent Network 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 Independent Network. Our installers respect your home and possessions, leaving you with beautifully installed uPVC windows and nothing to clean up afterwards.

That's Networkmanship

Some of our happy customers

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

Professional company with friendly workers. Offered good advice and gave a good price. Very trustworthy, were able to leave them in the house in our absence. Only negative would be lack of communication on some aspects of the job. Wouldn’t hesitate to recommend.

This is the third time Phil has done work for me and he has never failed to provide a n excellent service. He replaced an old patio door with a box bay window. He and Darren took great care with every detail, making sure we were happy and every was tidy before they left. The products he provides are of good quality and are guaranteed by Network VEKA. I would not hesitate to recommend them.
