This is what our customers say about us


Initially contacted CNS to solve a problem with our Server recently installed by another company, which kept crashing. CNS came on site and immediately took ownership of the problem and the issue was quickly and professionally solved. We have found that CNS have a rare mix of being very professional and competent, whilst also being easy to deal with. We have been using them for all our IT needs for nearly 20 years and would have no problems in recommending them to others.

We have been working with Robert and his team for over twenty years, from Wang OIS systems through to modern servers running specialist case management as well as general office software. CNS are available whenever we need them and have always proved thoroughly competent and professional. We highly value their support, assistance and guidance.

Limelight Entertainment Ltd has used CNS for around 10 years, it’s been one of the best decisions we’ve made for our business. They have looked after our servers, phone system, internet and personal computers perfectly and are always available on the phone if we have any issues. Over the years we’ve had issues (as everyone experiences) with services going down and CNS has been there on the end of the phone and remotely dialling in with their wealth of experience putting right any problem. From the moment you call them they spend their time sorting out your problem and they really know what they’re taking about when it comes to networking which is a rare skill. If you’re looking for effective IT management CNS are the people for you.
