From the time QES was founded in 1990 we have offered a range of electronics repair and design services for discontinued products, for aerospace projects, public and private bodies. We have a 99% return rate on all products and offer a free consultation to all new clients. If you need electronics maintenance, a power supply design and repair or need consultancy for your electronics, then contact us.

As well as producing and repairing our own products we repair power supplies made by any other manufacturers. Astec, Advance Power, Coutant, Cosel, Lambda, Liteon, Weir and XP Power are just some of the companies we have worked for and whose products we service to this day. We also provide replacements for obsolete power supplies. Our brochure explains this service and lists the models already available.

We have progressed from a Certified ISO9001:2008 certification in 2009. To make sure we honour our Quality Electronic Services promise all of our processes are systematically audited in house, by the BSI QA and all of our major customers.
