I can't recommend CAS UK enough. We had a Clarke for a couple of years that we abused running it 12 hours a day. We found CAS UK when it needed a repair, and we were very impressed with how quickly they responded and came out to repair and service the machine.
Our business started to expand and we needed a large compressor with a proper airlines feeding our machines and work stations. The guys from CAS supplied the new compressor and worked flat out getting the machine and pipe working in. They're a brilliant group of lads with a great work ethic and really easy to communicate with.
We'll 100% continue to use and recommend them.

What a refreshing team to have as competent suppliers for our leads and compressed air; not once have they given us poor service. They've saved our business; A Gilligan (Coatings) Ltd thousands of pounds per year with new high tech and efficient equipment. Their advice and service supplied over the last 15 year period has been extremely valuable, we would never consider another company for our compressed air services
