What People Are Saying

"When one of our IT team moved on to another organisation we required interim support until we found a replacement. As a national environmental charity we rely heavily on our IT systems so it was crucial that we maintained our levels of service. We met with System 15 who from the outset understood our operations and proactively suggested both technical recommendations and an implementation path for improvements. They provided expert advice on the technical issues we were facing and worked with our IT team not only to fix issues but to ensure the team were then in a position to support the changes internally. Put simply, if you have a technical issue that cannot be solved internally or you are looking to transition your IT to the next level then System 15 are the people you should call, I did and would do so again tomorrow."
Michael Sharp, Head of IT and Data - Marine Conservation Society

"ADEY engaged with System 15 to consult on a major IoT project that would drive the future of the company through its product road map. System 15 were ultimately asked by me to become ADEY's external partner to project manage a solution that could deliver a successful outcome. The development team at System 15 also designed and coded the full back-end functionality of the solution. By advising and liaising with 3rd parties on the design and development of the associated website and IoT device firmware, System 15 proved invaluable in delivering the successfully completed project to market. Finally, we needed to grow our internal capabilities and ensure that the software was provided for in terms of disaster recovery. System 15 took on the role of assisting one of ADEY’s internal software developers to up-skill for this purpose. I would have no hesitation recommending them."
Edward Davies, Former Chief Operating Officer - ADEY Innovation Limited

"System 15 complete all work professionally and quickly but what impresses me the most is the quality of customer care. Everything is explained simply and they make sure that everything works correctly. I never feel the frustrations that I have felt with other providers. We are so impressed with the work System 15 have completed on our network and laptop upgrades and the IT support that we receive. They provide contracted support for all our computing and audio visual equipment and we would recommend them to anyone."
Mr. D. Port, Deputy Head - Meadowside Primary School

"We have had the opportunity for many years to work closely with the individuals that now comprise the core of System 15. They have broad skills and experience in software development, and they have a strong understanding of client support. Since starting System 15 their underlying capabilities and beliefs are showing through strongly."
Mr. J. Munday, Director and Co-Founder - Blue Zebra Associates Ltd

"You can never know everything, that's why we use System 15, to fill that knowledge gap. As a small IT dept we have a limited set of skills but System 15 give us the rest when we need it. They are knowledgeable, professional and personable. Too many times in modern life you don't really feel like you are talking to an actual person, when you deal with System 15 you talk to individuals that can communicate, making something complicated easy to understand, they inspire confidence. Its a pleasure to call them our support provider."
John Headley, ICT Manager - Stroud High School

"System 15 provide software product development and IT support in an easy to manage package - what we need, when we need it. Future additions to our Warehouse Management System and IT systems management will be in good hands. A company going places!!"
Neil Smith, Distribution Manager - Deltaform Ltd

"As a small business we can’t cover all the bases, and IT support is something we have to outsource. System15 have been an excellent addition, allowing us to concentrate on our daily business, safe in the knowledge that our IT is being looked after. Cool in a crisis, nothing is too much trouble, and their ability to work with our software providers has meant that a potentially difficult installation of a new MRP system went off without a hitch. We can highly recommend the team at System15 and look forwards to working with them in the future."
Jane Butler, Production Planner - Online Engineering Ltd

"System 15 have been invaluable in keeping our IT infrastructure in top shape. As we do not have an in-house IT department we are reliant on System 15 to solve any issues quickly and efficiently which they do time and again. Would not hesitate to recommend them to others."
Jon Pert, Director - Moravia UK Ltd

"It has been a great pleasure to of worked on numerous projects with the team at System 15. From the initial briefing to the final delivery their knowledge was second to none. Nick and the team understood exactly what we were trying to achieve from the beginning of the project and they consistently deliver on time and within budget. We look forward to working with System 15 for a long time to come."
Adam Vines, Chief Executive Officer - Join In China

"Ferguson Snell & Associates Ltd have dealt with Nick Rowntree and his company for many years for IT data systems, maintenance and updates. I would highly recommend them for any IT matters that your company might need. Their response time is excellent and they are always easy to deal with especially if you do not have a good understanding of the technical computer world. They are good at listening to what your company needs and will then recommend the right system for your company and staff needs."
