How do I change cam belt on Citroen C5. 2,0 HDI?

My local mechanic changed to cam belt on my citroen c5 hdi. It took him 8 hours to change the cam belt, water pump, anti roll bar linkage rods, and perform a full filter and fluids service, including check and adjust brakes. This cost me £210.00 plus parts (approx £160) all inc. VAT.
