Just managed to source a replacement belt for my Hoover washing machine,
and was wondering how tight it needs to be fitted?

When fitted, how far should I be able to move the belt in and out at a
point half way between the pulleys,

Rule of thumb for alternator belts it about half an inch.
If you get any slip, tighten it up a bit more.

or is it just a case of tight as possible?

No -- that will more rapidly wear the motor bearings.
