I dont know why people get so pedantic about this, whether you call it HB or UC, it is the money that people get from the government to pay their rent.
It depends.
A PP was arguing that only half a million households in privately rented properties get housing benefit.
If "housing benefit" is just a loose term for all help with housing, right, that's only half a million.
But if it means the legacy Housing Benefit only, and the numbers getting thr housing element of Universal Credit are in addition, it's a larger number.
In the DWP's Benefits Statistics for August 2024, it says
"At May 2024, there were 2.3 million recipients of Housing Benefit (HB), a decrease of 130,000 on the last year. There were 1.1 million Pension Age and 1.2 million Working Age recipients. The number of Working Age recipients will continue to fall as claimants move to Universal Credit (UC). By comparison, 3.6 million households had a housing element as part of their UC assessment, of which 3.4 million were in payment."
So a total of 2.3 million + 3.4 million = 5.7 million households getting help with housing costs.
The breakdown of social rented and privately rented properties, giving us that figure of half a million, is only available for HB. How many of the 3.4 million getting housing help through UC are in the private rented sector?
