Director - Circle Wealth Partners

What a fantastic company. I have worked directly with Simon and Jill at Sitec IT for some years now and have continuously been impressed by their knowledge and experience at working with a business our size. We have many moving parts and Simon has been on top of it all, throughout Cyber essentials, new hardware for multiple staff and even an office move thrown in for good measure. Nothing has been too much for these guys and I highly recommend their services. Always available on the end of the phone or in person, and they are very good problem solvers, something which is essential in IT. Keep up the brilliant work.

Simon and the team are absolutely fantastic. Sitec has provided IT support for GASP Motor Project for over 5 years and the service remains as high as ever. No problem is either too big or too small, calls and emails are responded to in a very timely manner, and everyone is incredibly friendly. I highly recommend Sitec.
