Cost for cambelt replacement D1 200tdi

Hi all,

Looking to get the cambelt replaced on my 200tdi D1.

Is there anything else I should be doing at the same time? Assume water pump?

What are the prices on swapping these out usually? I could probably do it myself but do not have a lot of time on my hands, based in the south east in kent if anyone knows somewhere local.

Thanks
