Have they brought their fees down? The leaflet I have quotes 39.99GBP for the 'healthcheck'.
Also, what if they find a problem? Do they then charge the 50GBP fee for repairs too? (1st hour, then 25GBP per hour thereafter).
As mentioned above Norton Utilities is a good investment to sort out usual problems - I can't see why you would need a healthcheck from them on top of that (or instead).
My company charges for repairs at 40GBP ph, which includes the healthcheck/valet etc...which I think is more sensible since at least you are working on a problem (if it ain't broke don't fix principle).
