Housing rent is due to be paid every Monday throughout the year.
There are usually 52 Mondays in a rent year, so 52 weekly payments are due during the course of the year, which runs from 1 April to 31 March.
Sometimes there are 53 Mondays between 1 April and 31 March - and you will be liable to make 53 weekly rent payments. We call this a '53-week rent year', and it only happens every few years.
