  • Managed Business IT Support in Sussex, Surrey, and beyond

  • HealthPartners International have worked with CSE for over 15 years, we have found them helpful and responsive to our needs. They have developed a good understanding of our business and are always able to offer IT solutions to any challenge presented to them.

  • Customer Service Excellence is another way to describe CSE - professional, friendly and always willing to go the extra mile!

  • We have used CSE for all our IT Support needs for the last 7 years or so. They have always been quick to answer the phone and fast to respond to our problems. The reason we keep using CSE is mainly that when they come to visit they speak to us like people and not idiots the way many other IT companies do, it goes a long way when the engineers take an extra 5 minutes to explain in English what the problem / solution is. I would have no hesitation in recommending CSE to any business.

  • We have worked with CSE for over 10 years, we have always found their service to be top class, our calls are always answered straight away and any major problems we've had (not related to CSE!) have been dealt with in a timely manner, by friendly and professional staff. We as a company The Cruise Line ltd would have no problem in recommending their services to any other business's. 10/10 well done, keep up the good work.

  • Excellent company with first class staff who when in consultation have always had the time to listen to us meeting our IT support requirements and needs. Allowing Renovo International to remain efficient competitive and productive. P.M.Coghlan Managing Director Renovo International Ltd

  • CSE have provided our IT maintenance and support for over 17 years. We have been very satisfied by the level of service CSE provide. There is always someone available on the end of the phone and the engineers are unfailingly friendly and polite. The CSE team provide a wide range of expertise so there is always someone with the necessary know-how to address any IT issue that arises. I would have no hesitation in recommending CSE to any business.

  • We have been supported by CSE since June 2010. Peter Hook and team have always been helpful & informative; they have normally responded to requests for assistance in an efficient and timely manner; and they keep us regularly informed on upgrades and improvements needed for our computer network.

  • I have worked with CSE for a number of years so when I started by own company two years ago there was no doubt in my mind who I would appoint. As a specialist in Airline Representation, CSE knew what was required and have been very supportive from the start. The staff are very professional and customer service is excellent.

  • I've had a great experience with CSE. I've used them for live support for a while now and always get instant support when needed. My previous computer support company often made me wait for an hour or so before getting back to me, whereas CSE seem to be almost instant. Well done Dom and the team.
