Fantastic Service! Needed help setting up our firewall they were happy to guide me through every step, Would highly recommend.

When things went wrong Criterion had us up and running before 10am! Emailed Lee Smith at 8.30am and received a prompt reply “technician on the way”. Cant ask for more! Great service. Highly recommend.

I have used Criterion for 18 years and bought several full IT and telephone systems from them for my business. I have always found them to be extremely helpful providing advise and guidance from quotation to installation. They are always very competitive on price.

We have being using Criterion Systems for quite a few years and they have always been very competitive and their customer service is excellent. Would definitely recommend this company to all.
