The firm, part of the Leasedrive Group, puts the increase down to fleets replacing pool cars with rental vehicles.
Roddy Graham, commercial director of the Leasedrive Group, said: ‘Our experience over the past four years has shown that mid-term vehicle rental is often overlooked.
‘However, there are signs now that companies are beginning to identify the savings to be made from mid-term vehicle rental over more traditional methods of providing temporary transport.
‘Currently, seven of our top 10 leasing and daily rental customers regularly use mid-term rental.’ The average rental length is two months and visitors from overseas and new employees on probation account for 90% of its business.
Graham added: ‘What some customers do not appreciate is that if you have a rental vehicle for more than 14 days, then you need to report motor insurance and P11D details. ‘Our online registration makes this a virtually invisible process.’
