The Mountfitchet Group companies: A history of aviation.

Air Charter Service

As the son of a pilot, Chris Leach had aviation in his blood, and in 1990 from the basement of his home in Kingston Upon Thames he looked at the aircraft charter market and saw an opportunity. He believed that if you went that extra mile for your customers then they would always come back and with that blueprint he would build a business, thus Air Charter Service (ACS) was born.

Decades later, with a network of offices spanning North America, South America, Europe, Africa, CIS, Middle East and Asia, ACS is the proud supplier to thousands of clients worldwide, in fact we arrange 25,000 charter flights every year.


Voluxis started life as Berrard Aviation, before joining the Mountfitchet Group in 2016 and undergoing a full rebrand. Today, Voluxis has offices in both London Biggin Hill and Farnborough, and offers a fleet of high performing aircraft, as well as a range of services including private charter, aircraft management and sales & marketing.
