This is partly for helvella but also for others looking for liquid Levo at the moment when it's been scarce.
By a mishap I ended up with a repeat prescription a bit early for my liquid Levo, so I bravely phoned the independent pharmacy and they actually had a bottle on their shelf (extra gold stars). So I rushed down there and picked it up with the balance remaining, but it's a type not mentioned on the T UK website. Can't see your list Helvella as the dropbox link wasn't working. It's by BrillPharma. Maybe it's been rebranded but they do seem to specialise in liquids. Thought people aught to know it's at least possibly available at the moment.
