Right, isolation valve under my sink (hot pipe) is leaking from the tap when open enough to get a decent flow. Guessing that means it needs replacing (or fixing?)
In any case, can someone advise where I'd need to turn the hot water tap off so I can remove the offender and replace?
I don't have a combi boiler so I'm guessing that water might come from the hot water tank?

With the tap closed, try to loosen and retighten the gland nut, if that does not work, remove the gland nut and add some thread tape around the spindle so that the gland nut compresses it into the gland packing housing.
Do not overtighten, tighten just enough to stop the leak.

thanks - will try this
gland nut being the little nut just below the tap?
when you say remove the gland nut, i assume this is with the tap closed still, just unthread the gland nut until it's essentially off, pop some ptfe in then pop the gland nut back on?
