Motor Transport understands Cheshire-based trailer manufacturer Cartwright Group has filed a notice to appoint an administrator.

Calls to the Altrincham family business went unanswered but it is understood that the company has filed a notice to appoint Deloitte to handle its affairs.

Cartwright Group can trace its history back to 1952 and it has grown into one of the UK’s leading trailer and commercial vehicle body and conversion manufacturers.

In June, the group hailed its employees for their work in keeping the company operating through what it described as an “unprecedented period”.

It added: “As we move into July and our production facility is returning to normal operations, we are looking forward to getting back to ‘business as usual’.”

In 2016 Cartwright Group won a Motor Transport award for its apprenticeship scheme.

Six years earlier, former Cartwright Group joint MDs John and Steven Cartwright set up trailer manufacturer Tiger Trailers in Winsford, Cheshire.

A Deloitte spokesman confirmed it had not yet been appointed administrator but declined to comment further.
