Where abouts in Wiltshire are you?
There are a couple of great specialist in the Oxford area if you fancy a short drive..
Your noise could be the waterpump, alternator or even a cambelt bearing.
The garage might take the auxillary belt off and start the engine to see if the noise is still there. If the noise goes when the belt is off, then it isn't anything to do with the auxillary belt.
To be honest though if the variator is rattling, you are probably better off getting all of the belts, tensioners, variator and waterpump done.
