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...

Marc & his team fitted a Guardian roof system to my 25sqM L shaped conservatory. The system was assembled and covered in metro tile within 3 days of getting underway. The roof was completed internally and skimmed in under a week. A couple of fitting issues were personally resolved by Marc. Communication was good, with Marc responding to emails and texts promptly, the team arrived when agreed. The Guardian system is type approved to meet Building Control but doesn't give an automatic 'pass' . The roof has given us 25 sqM of welcoming, usable space which replaces the too cold/damp/too hot/dazzling dumping ground it had become. We couldn't have achieved that for the same cost any other way. I would use Marc again.

Friendly, efficient service - from ordering to completion was around 4 weeks. One of the glass panels had to be replaced but this was sorted quickly and the final finish is excellent. Was recommended VEKA by family, and based on our experience would definitely recommend both the windows and the company.

This is the second time we have had BMW Building Products do a job for us .The first was two sliding doors 3 years ago and the last was a large kitchen window and all were fitted to the high standards we expect from any company but don't always get. With BMW you get the personal service and an excellent job finished to a high standard and everything cleared up after they have finished and a special Thank You to Barry who fitted our kitchen window. Thank You again. Denis & Mercel.

From start to finish Daryl and his team were friendly, professional and worked really hard. The plasterer did an excellent job . We are really pleased we made the decision to have a warm roof fitted to our cold north facing conservatory. We would recommend Daryl and his team.

Very pleased with our Supalite warm roof, the quality of materials are excellent and the finish spot on. There was no pressure sales and no gimmicks offered. I would recommend Colourchange UPVC

Had them out for quotation may not be the cheapest but the workmanship is second to none. Had my work completed and the customer service was impeccable, the workmen themselves treated my property with respect and were extremely polite and courteous, cannot recommend this firm highly enough. The service, the quality of materials and the workmanship is a good reflection on the price, worth every penny.
