Cheers madrab, my thinking is if he can't fix the leaks after a second visit I'm better off finding someone who can... Don't mind how it looks too much as it's quite out of sight in tight space between cistern and wall, but in this case it looks so unsightly I suspected that's whats causing the leaks, kinked flexi hose pulling on the join and the random bit of plastic leaking at both ends. To be clear, if it was initially leak free I wouldn't have paid much attention to it and would be quite happy, but as it leaks, it's drawn my attention to the weird setup and I'm questioning if it needs redoing completely. Hope I've made sense
