Renters could almost twice as much as homeowners, and could report housing costs rising over the past six months, the Office for National Statistical Data shows.
According to the Number Watchdog, 39% of tenants say they are more likely to complain of a rise in rent compared to 22% of mortgage holders who reported higher mortgage payments. 
41% of renters added that in the sector's latest public opinion and social trends survey, it is more likely that payments will be seen as “very or slightly difficult” compared to 26% of mortgage holders.
Also, 43% of renters were more likely to report “cannot afford” an unexpected cost of £850, compared to 20% of mortgage holders.
Data came after the relaxation of the cost of living, which was relaxed to 2.6% for two consecutive months. Official figures showed on Wednesday that it was much lower than the 11% inflation peak seen in 2022.
However, in March, average UK rents rose 7.7% to £1,332.
This annual growth rate has declined from 8.1% annually to February, but is almost three times the headline inflation.
A wide range of tenant rights bills have passed through Congress. This proposes limiting annual rent increases and banning Section 21's non-disabled eviction.
Ventumei, CEO of Generation Rent, said:
“When we are forced to spend a lot of our income on rent, the impact will ripple over the rest of our lives.
“Our energy and water bill prices exist right, but nothing stops a landlord from hiking the cost of someone else's home all of a sudden.
“Thankfully, the government can and must act on this by limiting the amount that landlords can increase rent.
In contrast, mortgage owners have seen a base rate cut of four-quarters since August fell to 4.5%.
However, according to UK finances, around 1.8 million mortgage holders are planning to refinance their mortgage this year. This means moving to more rates than the market has offered in the last 3-5 years.
