Well I'd definately want clarification of what's included if I was booking my car in.
To be honest, if that's just the price of the service you could end up with a very large bill if any other work is needed (discs, pads, bearings, bushes etc etc)
Bit further out but might be worth considering one of the recommended specialists on here such as Ollie in Horndean or TM Motors in Molesey etc.
