A battery is committed when a person intentionally and recklessly applies unlawful force to another.
It is a summary offence, which carries a maximum penalty of six months' imprisonment and/or a fine not exceeding the statutory maximum. However, if the requirements of section 40 of the Criminal Justice Act 1988 are met, then Common Assault can be included as a count on an indictment.
