The maximum sentence for armed robbery in the UK is life imprisonment, but this is typically reserved for the most serious cases. In most cases, armed robbery will result in a sentence of several years in prison. For example, the average sentence for armed robbery in England and Wales in 2018 was 8.5 years.
In addition to a prison sentence, armed robbers may also be required to pay compensation to their victims, and may also be subject to additional penalties such as drug treatment or community service.
