Landlords have come under renewed criticism for reduced mobility among younger people and a lack of housing affordability.

Two separate reports have blamed the rental market for issues in the housing sector.

A report by the Resolution Foundation, based on ONS data, found that young people are moving jobs and to new areas less than they were 20 years ago.

Its analysis of official labour market statistics found that just 18,000 young people started a new job in a different area and moved home last year, compared with 30,000 in 1997.

The report acknowledges that local job availability has improved and the gap between wages among different local authorities has narrowed, but said young private renters are only one-third as likely to switch jobs and homes as they were 20 years ago

This was blamed on rental growth outstripping earnings in 165 out of 324 English local authorities.

Meanwhile, the Affordable Housing Commission (AHC), set up to examine how best to define and measure housing affordability, has proposed a new definition in its interim report based on when rents or purchase costs exceed a third of household income.

Using this measure, the AHC found there are 4.8m households with affordability issues, equivalent to a fifth of all households.

This number has increased by more than 0.5m households since 2010, with the largest rise in the private rented sector, the AHC report says.

The 4.8m figure consists of 2.9m struggling renters, 1m low income older households and 0.9m struggling home owners.

A full report on a new definition will be published in early 2020.

Landlords have hit back at the findings of both publications, claiming the issues of mobility and housing would be helped if the buy-to-let sector wasn’t under attack from tax and regulatory changes and if more homes were built.

David Smith, policy director for the Residential Landlords Association, said: “The biggest threat to rent levels are the policies being pursued by the Government which are choking off the supply of homes for private rent as demand is increasing.

“We warned ministers that this would happen but they have not listened.

“Instead of attacking the private rented sector we need pro-growth policies that recognise the need for more homes of a good standard and at an affordable rent.

“Making renting less attractive for landlords will not make a substantial difference to the availability of property. We must focus on building more homes to address this.”
