Law Man1856 suggests a possible ABH charge due to the 'kicking on the floor'. However, the difference between 'Section 39, common assault' and 'Section 47 of the Offences Against the Person Act 1861, i.e. "Actual Bodily Harm"' is determined solely by the nature of the injuries, not by the manner in which they were inflicted. (The manner in which injuries were inflicted only comes into play when considering 'GBH' under sections 18 and 20 of of the Offences Against the Person Act 1861).
I've already provided the link for the definition of 'common assault' which is used by the CPS when determining the correct charge to apply. It seems to fit in with the injuries you describe. However, if you want to read the definition of 'ABH', it's here:
