They were awarded the title based on their ongoing work installing and maintaining Otterbine’s aerating fountains throughout the country.
Topturf’s Colin Clark said: "We are delighted to have won this award for the fourth year running. Our success is testament to the team’s hard work and dedication – although it does make our job easier that Otterbine is the Rolls-Royce of aeration.
"I believe our unique rolling maintenance programme, which provides constant support to customers rather than waiting until a machine breaks down, makes for an award-winning service."
Otterbine distributor Lely’s Roger Lupton commented: "Topturf’s success shows just what can be achieved when you partner a great product with high standards of installation and service.
"Thanks in particular to its team of Otterbine factory-trained installers, Topturf provides an excellent all-round service that ensures customers get the most out of their Otterbine for the lifetime of the unit. Congratulations to Colin and his team for a deserved win."
