Hamptons said this was the highest proportion of income going on rent typically since its records started in 2010.
With household bills added, the average tenant household spent 52% of their post-tax income on bills including gas, electricity, council tax, broadband and TV licences and rent last year, Hamptons estimates, adding up to £16,910 typically.
