At the end of last year, the manufacturer had a 140-strong dealer network, which included seven fleet specialists and by the end of the second quarter of this year will increase this figure to 15.
Each will have a dedicated corporate sales manager and a corporate demonstrator fleet.
Mazda fleet and remarketing director David McGonigle said: 'The 15 fleet specialist dealers are located throughout the UK. However it is important that we recognise that all Mazda dealers are equipped to sell fleet and we have established a programme to encourage just that.
'The fleet specialists have relationships with major blue chip customers and contract hire and leasing companies, while the rest of the network is focused on winning more localised fleet business.
'Many companies have recognised the unique proposition we have. However, to help further expand our fleet business our dealers must be our 'eyes and ears' at a local level.
'Research shows that our dealers already enjoy a fantastic relationship with existing Mazda customers and we want more fleet decision-makers and company car drivers to enjoy that experience.'
The announcement comes a week after a Sewells report revealed fleet managers believe there are not enough fleet experts at dealers.
