i hate saying this but i am going to have to pay for my mantis tiller to be serviced it has got a fault on it and i have not got the time to spare to do it myself question is roughly how much should it cost

Haven't got a clue, I'm afraid.
The company I work for charges £38 per hour + parts + vat, and we're pretty cheap for the area we're in.
I expect that the further north you go, the cheaper it gets (generally  )
