We estimate that there are approximately 80,000 single claimants under 35 without dependent children living in the social sector who currently receive more than the relevant local housing allowance rate. However, not all claimants in this category will be affected by the announced policy as it will only apply from April 2018, where a new tenancy is taken out or a tenancy is renewed after April 2016. Tenants who take on a new tenancy or renew a tenancy will have the opportunity to consider whether they can afford to take on the property before committing to it. As such it is not possible to accurately estimate the proportion of single people without children that will be affected by this policy in 2018. As the overall estimate is based on survey data, it is not possible to provide an estimate by Local Authority due to sample size issues.
