Hi Alvin,
Every floor must meet a certain level of slip resistance to be deemed safe by the HSE (in both wet and dry conditions). 99% of hard floors meet this in the dry, however 99% of these fail when some sort of contaminant is present e.g water, oils, flour. It is up to the premise manager/owner to carry out their 'duty of care' and to provide a safe, non-slip floor.
There is a testing apparatus called the pendulum slip resistance tester that can determine whether a floor meets the slip resistance level that is set by the UK Slip Resistance Group and the HSE. If a floor meets the slip resistance value then there is no negligence, therefore no compensation and other factors may come into play for example the plaintiffs footwear, state of mind etc, if the floor doesn't meet this level then there is negligence, even if the plaintiff was an intoxicated gentleman in a pub wearing high heels, the underlying factor would be the floor doesnt meet the set slip resistance level.
