    Just spotted some greern flakey residue on the stubby copper pipes
    that come out of the floor into a first floor radiator. i.e. just
    under the valve. I've got it on two rads. I can't feel any water but
    could it be the start of a leak or is it something else?

    It's most likely a very slow leak, ie water is slowly leaking but
    evaporating before you can detect it, leaving residue. The green stuff
    is the effect of corrosion on copper.
