We are trying to lift vinyl flooring that has been glued very firmly
in place. We have bought a special tool (like a paper scraper but bigger)
but it
still doesn't come up very easily. Can anyone suggest the best way to
remove it.

Did this recently using my SDS drill in chisel mode and a 75mm tile-removing
chisel. Worked brilliantly but watch out for your eardrums - and the cost of
the chisel (£30 from Screwfix and others say they break easily if you don't
think about where the forces are applied and follow the instructions
carefully). May not compute if you don't already have a rotation-stoppable
SDS drill but otherwise I fear you are doomed to an awful lot of manual
labour with your paper-scraper-but-bigger.
