A company spokesman declined to name those affected or say how many have lost their jobs. But he stressed that as part of the review the firm is about to make a senior appointment in its fleet department.
In a statement, the company's trading director David Hall said: 'Since taking over in January, I have reviewed our entire fleet operation. One of the key appointments we are set to make is that of a fleet sales director to ensure we have a strong focus on our key customers. As a result, we have decided to make some changes.
'We are committed to growing our fleet business and in order to do so we need to ensure our sales and marketing structure reflects customers' needs.'
The firm has more than 540 centres across the UK, employs about 4,300 people and is part of the Euromaster Group, which operates in 10 European countries.
