MOST tenants in their 20s are spending an average of 34 per cent of their pre-tax incomes on rent, new research has revealed.

Analysis of 20 major cities in the UK found Brighton is the least affordable city to rent a room – taking up 35 per cent of a 20-something’s pay cheque.

London was in second place. But stronger income growth has meant that tenants in their 20s are typically spending less on rent than before.

Sheffield was identified as the most affordable city on the list to rent a room, with rent accounting for 25 per cent of a tenant’s income.

The research suggests tenants looking for a one-bedroom home for themselves face paying 31 per cent more than if they rented a room in a house share.
