I've had some water lillies in my fishpond for a couple of years

They had flowers on them when bought, but haven't flowered since -

The pond started to leak so I've taken everything out to see if I
can
re-seal it. It had a liner before, well bits of liner were still
left,
and I'm not sure if the bituminous sealer will be the ideal
solution.
Any suggestions as to what to look for in a pond liner? It is a
pretty
small pond around a metre square and thirty centimetres deep.

What species and variety are they? Your pond may not be deep enough
for them, as I think you need at least a foot above the rootstock
even for the smallest. I also wonder if there are too many -- you say
"water lilies", plural.
