About AC Metrology
AC Metrology is the trading name of Ascott & Cooper Metrology Ltd, a specialist dimensional metrology company based in Derby.
We supply granite and cast iron surface plates, alongside a range of metrology equipment, and provide specialist calibration, resurfacing and servicing of surface plates to BS 817:2008. Our services also include the servicing and calibration of CMMs and other precision measuring equipment and gauges.
In addition, we work closely with manufacturers to identify and resolve measurement challenges, developing practical solutions to improve accuracy, repeatability and efficiency while reducing downtime.
Based in Derby, we support customers throughout the UK and Ireland, with international services available upon request.
The company was founded in 2026 by Luke Ascott and Andy Cooper, who between them bring more than 20 years’ experience in UK dimensional metrology and over 1,000 calibrations across their careers.
The team
Director
Luke has worked in dimensional metrology for 9 years. He spent 4 years as a field service engineer, working on CMMs and horizontal arm machines, resurfacing and calibrating surface tables, and servicing digital height gauges, before moving into sales. Like Andy, he built that experience at Eley Metrology.
Director
Andy has 11 years of experience in metrology and precision engineering, working his way up from engineering apprentice to Director of Eley Metrology. His work has covered granite surface table calibration and resurfacing, digital height gauge assembly, servicing and calibration, CMM servicing and calibration, and subcontract CMM inspection, and throughout his career he has worked in a UKAS-accredited environment. He also has extensive hands-on experience of CAD and precision manufacturing, including lathes, milling machines and surface grinders, so he understands the practical problems customers face on the shop floor as well as in the inspection room.
Industries we work with
Our team’s experience covers aerospace, automotive, medical, nuclear, defence, rail, oil and gas, food and drink, precision engineering, and inspection and QA labs.
