Quadron starts the five-year contract for Teignbridge District Council next week and says it will save the authority £50,000 each year.
The company beat five other contractors to win a tender bid to look after 400,000sq m of grass, 20 sports pitches, three bowling greens, 1500sq m of flower displays, hedgerows and shrubs. The fixed-price contract was set by the local authority.
A Teignbridge representative said: "A 21 to 26 per cent saving has been built into the contract budget. The budget will be reduced by £50,000 per year."
Lorraine Montgomery, service manager for green spaces, said: "We will make savings by working smarter. One of the main ways will be to use community groups to pick up some of the work."
Councillor Anne Fry, spokeswoman for recreational services said: "To secure such a competitive deal that saves taxpayers money would in itself be cause for celebration but there are added bonuses."
These include a Quadron proposal to take on apprenticeships, redevelop a glasshouse facility for community groups and recycle green waste from grounds upkeep.
Quadron managing director Clive Ivil said: "The council has taken an innovative stance in this age of austerity by fixing its budget for the next five years and challenging contractors to provide a community-focused, output based service."
