New survey data from Hodge Bank has revealed that unexpected monthly expenses are placing significant financial strain on UK households. Over a third of Brits (34%) report that they have fallen behind on at least one bill in the past year due to unplanned costs.

The findings show that rising everyday expenses, such as household repairs, medical bills, and surprise travel fares, are disrupting monthly budgets and causing many people to miss essential payments.

Nearly a third of Gen-Z and Millennials have admitted that they have frequently fallen behind on bills, with 43% of 18–24-year-olds admitting unexpected costs have forced them to fall behind on bills once or twice.

By contrast, those aged 65 and over appear to be more financially resilient, with just 9% reporting falling behind on bills due to unexpected costs, suggesting that older generations are better protected against financial shocks.

The data demonstrates a significant divide between older and younger generations, with only 15% of those over the age of 55 stating that they’ve fallen behind on bills because of unexpected costs. Compare that with those aged between 25-34, and a staggering 40% state that they have fallen behind on bills as a result of unexpected costs.

“These results highlight the growing financial fragility facing many UK households,” says Christie Cook, Managing Director of Retail at Hodge. “Unexpected costs are not just inconvenient. They are actively preventing people from paying essential bills like rent, utilities, and council tax. For younger generations in particular,” continues Cook, “the line between just about managing and falling behind is becoming increasingly thin.”

“As prices continue to rise and financial unpredictability becomes more common, many are finding their ability to plan ahead severely limited,” Cook observes. “This data increases the need for accessible savings options that can offer support when sudden expenses arise.”

The findings emphasise the growing impact of unexpected costs on household finances across the UK and highlight the importance of planning and financial resilience in an increasingly uncertain economic environment.
