Posted on April 2, 2015

Shefford, February, 24, 2015, DM Systems and Test Group (DMG), specialist in engineering services, announces the acquisition of Applied Quality Assurance Limited (AQA), a privately held calibration provider.

The acquisition of AQA, established in 1981, allows DMG to consolidate and expand the capability of its calibration business, providing a competitive edge whilst offering a greater range of services and support to its customer base throughout the UK.

Ken Ward, Managing Director of DMG (formerly General Manager of Dowding and Mills UK Limited, Calibration Division) said, “We are delighted to welcome AQA into the DM Group.  Combining our investment and operational capabilities gives us a leading offering in this market. This acquisition will spearhead our strategic growth plans ensuring that DMG capitalises on the numerous exciting opportunities that have been identified.”

Over the next few months DMG will integrate this new company into its group with the goal to continue providing the highest level of service during this time and fostering its long and mutually beneficial relationships with its customers.

Doug and Margaret Healiss, the previous directors and owners of AQA, were careful to ensure they selected the right buyer for their business, which they have built over the past 3 decades. Both Doug and Margaret will remain with the business for an extended handover period and remain integral to the business for the short term, but at least 12 months.


AQA provides comprehensive Mobile, on-site calibration services supported by a permanent Laboratory offering 48hour turnaround, by arrangement. The scope of calibration covers dimensional, torque, pressure and mass with the Mobile Service catering for all of these requirements, including Thread Gauges. All calibration is traceable to National Standards and the Mobile units are environmental controlled to 20+/- 2 °C.


DMG is a specialist engineering services provider to the UK and overseas commercial and defence markets. Services include calibration and repair of test and measurement equipment; design, manufacturer and support services for subsea communications systems and navigation aids; and supply and support services for EMC and satellite communications equipment.

With the acquisition of AQA, DMG is enthusiastic about further developing its many relationships in the various markets and to supporting its existing and prospective customers.
