From first contacting Alan Campbell Engineering Services (ACES) in an effort to resolve a problem with a power unit, our issue was dealt with promptly and professionally.

After discussing the options available to us, we elected to ship the unit directly to ACES for evaluation. On receiving our unit, they fast- tracked it through their facility and identified the problem within 48 hours. As our power unit forms part of a system, they sent an engineer along with the repaired unit, so that this could be fitted and checked before sign off of the repair.

I would have no hesitation in contacting ACES in the future for any similar issues arising with our equipment.

I would highly recommend ACES to other Telecommunication and related companies. I have recently used ACES on a major Inverter refurbishment project and found them to be professional and easy to deal with during the lifecycle of the project.

As part of the C&W contract we at Mitie have been using ACES for the last five years. They offer an excellent service across the board, excellent turnaround times with a high level of technical knowledge. I would recommend them to anyone.
