Customer Testimonials


My company used Advance Product Services Ltd to carry out and present MTBF calculations to MIL217F on a range of uninterruptible power supplies. We chose APS because of their expertise, experience and good value. We were delighted with the quality of work which enabled us to fulfil an obligation with one of our customers much more quickly than if we had carried out the work ourselves. I anticipate using APS for power systems design work in the future to supplement our own engineering teams, knowing that they have the discipline, knowledge, experience and relational skills to integrate, work and deliver within a larger organisation

David Heaton EP Systems PLC

A very approachable and friendly organisation who seem genuinely concerned about both their products and services. I would have no hesitation contacting you about any product you list. Thank you for a very positive experience.

Derrick Marsh - Private Individual

An excellent service, good value, with turn around times much faster than quoted. Thanks, we'd almost given up on getting this item repaired.

Phil Jones - Humberside Airport

I have recommended APS on a number of occasions. They have certainly sorted out a lot of long running problems for us, it's very good.
