New suppliers have now taken on 9,073 Carillion workers, it said.

However, the firm’s collapse has resulted in more than 1,700 job losses to date, while a decision on the future of another 6,400 employees, who are currently retained to enable Carillion to deliver the remaining services it is providing for public and private sector customers, has yet to be determined.

A further 123 staff will leave the business later this week as the programme of redundancies rolls on.

A spokesperson for the Official Receiver said: “A further 481 jobs have been saved with employees transferring to new suppliers who have picked up contracts that Carillion had been delivering. More than 9,000 employees have now been found secure ongoing employment.

“Regrettably we have been unable to find ongoing employment for a further 123 employees who will leave the business later this week. Jobcentre Plus’ Rapid Response Service will provide them with every support to find new work.

“Discussions with potential purchasers continue. I am continuing to engage with staff, elected employee representatives and unions to keep them informed as these arrangements are confirmed.”
