Latest Office for National Statistics (ONS) figures shows that tenants renting from private landlords have seen the highest rise in rents since comparable records began seven years ago.
Rents rose 4% last year as landlords passed on the costs of higher mortgage rates. A poll of tenants surveyed in December saw a quarter say their rent had risen in the past six months.
On average, renters pay 24% of their weekly expenditure on housing compared with 16% by those with a mortgage.
