Cambelt/water pump typical price?

[No1gooner]

Hi all
Just comeback from the dealership after a service and VW recommend my cambelt/water pump needs changing as there's no record of it being done, cars done just over 48,000 on an 06 plate, VW quoted me a price of £519 just wondering if that seems reasonable or can it be done cheaper? Anyone recommendations from members who have had the work done would be appreciated!
Thanks
