The last 20 years - A history of PSU

When PSU was formed in 1986 it's core business was the maintenance, support and repair of PC's, servers, printers and IT networks for large organisations across the UK. Throughout the 80's and 90's the company lived and breathed the ethos of good service. When British Standards launched it's BS5750 standard for service, PSU adopted it from the outset and gained accreditation in 1994 making it one of the first companies in the industry to adopt this exacting standard.

Throughout  the late 90's the directors could see that the voice and data industries were converging and the companies that were going to survive in this soon to be merged market were the one's who could deliver on their promises of good service and support. The directors brought in the people who had the skills in InterTel maintenance and then embarked on a process of cross-training all the customer facing staff in both disciplines.


This early investment in knowledge coupled with the experience gained over the previous 15 years and then put within a framework of total quality explains why the PSU Technology Group is as successful as it is today at maintaining InterTel Telephone Systems
