Study Finds Digital Banking Tools Save UK Households £3,500 Over Ten Years

A study commissioned by Lloyds Banking Group estimates that smarter use of banking apps could save the average UK household about £3,500 over the next decade. The research, led by John Gathergood, a professor of financial economics at the University of Nottingham, projects that expanded adoption of these tools could unlock roughly £100 billion in total economic value across the country.

The report lists seven areas where banking apps already help or are expected to help users within five to ten years. These include accessible investing, debt management, mortgage switching, credit access, insurance optimisation, money management, and financial capability.

Gathergood said many savers keep money in cash ISAs instead of diversified stock-market funds and that apps could soon identify suitable users and present investment options matched to age and risk profile. He added that providers are beginning to roll out these features.

On debt, the study estimates households could save around £15 billion by using app alerts that show when savings could pay down higher-interest credit-card balances. Gathergood said some banks have started offering these debt-financing suggestions.

The report notes that most UK mortgages are short-term fixed or discounted deals. Gathergood said apps can already flag when a deal is ending and display alternative rates, a function introduced several years ago. For credit access, the study highlights gaps for younger people and migrants who lack traditional credit histories.

Gathergood said new data sources such as rent-payment records could be added to credit files, allowing faster scoring and broader access to products. Insurance optimisation remains prospective. Gathergood said transaction data could eventually identify life events that change insurance needs, but such features are not yet available and are projected for five to ten years ahead.

Gathergood said future cross-bank data sharing could alert users when savings in one account could clear an overdraft or credit-card balance held elsewhere. Some apps already provide single-bank alerts of this type. The study also links improved financial capability to an additional £8 billion in household savings through better everyday choices.

Gathergood stressed that users must still authorise any transaction. Jas Singh, CEO consumer relationships at Lloyds Banking Group, said repeated small gains across millions of users could produce larger aggregate benefits for individuals and the wider economy.
