Nearly seven in 10 (69%) people are concerned about their personal finances and ability to cover the essentials, according to a survey carried out in September.
This is an increase from 57% who said this in July and 62% who felt this way in August, according to the research carried out for Nationwide Building Society.
A third (32%) of those in the latest survey said they are left with £100 or less in their account at the end of each month, with one in 11 (9%) saying they have no money left.
Nationwide’s own internal figures, based on data from its members, also showed that spending on mortgage payments in August was up by 11% annually, by value.
The total value of spending on rents surged by 19% annually in August.
The value of spending in discount stores increased by 28% annually in August.
The survey research was carried out among more than 2,000 people across the UK by Censuswide, between September 13 and 15.
Mark Nalder, payments strategy and performance director at Nationwide Building Society, said: “Money worries have peaked this year, which is perhaps not a surprise after many people juggled the expectation to spend during the summer with continued high living costs.
“As we enter the autumn, households will hope for some respite before the return of colder weather and the need to heat homes once again.
“While energy costs have dipped from their peak last year, the return of high utility bills will not be a welcome sight for many. Just as we saw last year, we expect many to cut back into their discretionary spending in order to manage their budgets.”
