Universal Credit
There is money for rent and some service charges. This is called the housing element.  In every area there is a Local Housing Allowance for people renting private property.  Help is limited to this level.  It was set at the rent of one of the cheapest 30% of homes in the area in 2012. There are different levels for homes with different numbers of bedrooms.  It was increased in September 2019  but since then in many places rents have risen more than the allowance.  Two-thirds of lower income privately renting households have to find at least a quarter of their rent.
