The 3.5-tonne long wheelbase platform cabs are being supplied by East Midlands dealer RH Commercial Vehicles (RHCV).
Bloomfields secured European Whole Vehicle Type Approval in six months with the Renault Master, in contrast, it says, to the three years it has taken with other manufacturers.
Dean Moody, owner of the Boughton-based business, says: "Renault Trucks and RHCV have been extremely responsive partners, providing first-class service and technical support, as well as manufacturing what we think is the most reliable and long lasting vehicle on the market.
"The Renault Master feels more robust than others and, together with our reinforced status-tested bulkhead that separates the horse from the driver, we think we have a vehicle that is as strong and as safe as possible for both passenger and horse."
