Annual update of formula rent and rent cap levels

In September each year the annual Consumer Price Index (CPI) figure is set which is used to establish limits on rents for social housing. The Rent Standard sets out requirements for how social rents should be increased.

Formula rent is used to calculate social rents. Rent caps set the maximum that can be charged for a social rent. These figures change annually because they are linked to CPI. The limit on annual rent increase documents include:
