Budget has brought its uninsured loss recovery (ULR) operations in-house in a blow for former outsourcing partners Albany ULR and ULR Norwich.
The move follows a decision to boost efficiency and control over customer service at the broking group.
The work will be done by Budget's claims handling operation ACM, whose ULR director Bob Perry said the business was now capturing 80 to 100 new ULR cases a day.
If continued for a year, this figure implies the loss of up to 26,000 cases annually for Budget's former outsourced ULR providers.
Perry said: "It was a strategic decision that was made within the company to bring the service in-house.
"We feel we can have a higher control over the service and it means the client isn't going from pillar to post."
ULR Norwich chief executive Nigel Sayer said the bulk of the work had been held by Albany ULR. Norwich ULR had extended its relationship with Budget in household business.
