UK Budget: Healey addresses £3 trillion debt and defense gaps

British households face a 16 percent jump in energy bills starting in January, a change driven by the government's price cap increase. This rise follows a period of high global oil prices linked to the conflict in the Middle East and the closure of the Strait of Hormuz. The upcoming budget will outline how the government intends to manage these rising costs while addressing a debt burden that has reached historic levels.

Chancellor John Healey is scheduled to present the UK's autumn budget to parliament on Wednesday at 12:30 GMT. It is the first fiscal plan under Prime Minister Andy Burnham's administration. The announcement comes as total UK borrowing exceeded 3 trillion pounds ($3.99 trillion) in September. The government now spends approximately 100 billion pounds ($133 billion) annually just to service that debt.

A central priority for the budget is funding the nation's defense plans. Prime Minister Burnham stated on Monday that his government's first challenge is financing the already announced investment plan. The plan, revealed in June, involves 298 billion pounds ($396 billion) in investment to transform the armed forces. Britain currently spends about 2.6 percent of its GDP on defense. The government aims to reach 3 percent of GDP by 2030 and 3.5 percent by 2035 to meet NATO commitments.

The Guardian reported that Healey aims to close a 4.7 billion pound ($6.2 billion) funding gap in the defense portfolio inherited from the previous leadership. To cover this shortfall, cuts to other departmental budgets are likely. The Treasury is also expected to introduce new taxes on banks and online marketplaces. The four largest banks reported profits of roughly 15 billion pounds ($19.9 billion) in the first half of 2026. A change to the 2023 bank surcharge rate is expected to raise about 2 billion pounds ($2.6 billion).

Healey is also set to propose a tax on foreign sellers on platforms like Amazon, Temu, and eBay who currently avoid paying VAT. This measure is expected to generate up to 1 billion pounds ($1.3 billion) in revenue. The funds will help finance business rate cuts for high street shops. Additionally, the budget will allocate approximately 1.42 trillion pounds ($1.8 trillion) for day-to-day spending and public investment this year, with 100 billion pounds ($132.8 billion) dedicated to debt interest payments.

Helen Miller, director of the Institute for Fiscal Studies, warned that a "steady-as-she-goes" approach is no longer an option for the chancellor. She noted that borrowing is still expected to fall in coming years and that fiscal rules are currently being met. However, she argued that staying the course with inherited plans would allow inflation to push departmental spending off track. Jasper Kanter, a professorial research fellow in ecological economics at Aberystwyth Business School, echoed the need for targeted support rather than large-scale tax changes.

The government has already announced several measures, including ending the carers' allowance limit and removing tariffs on specific food items like chocolate and beans. Pensioners will see a new personal allowance that shields them from income tax. The state pension will receive a substantial increase, while the minimum wage for low-paid workers will also rise. Healey is expected to add 1 billion pounds ($1.3 billion) to the 39 billion pounds ($51.8 billion) planned for social and affordable housing in England over the next decade.

A new national care service providing free personal care for the elderly is also part of the plan. Burnham announced this initiative last month, noting it would be funded by public spending and savings from scrapping the state pension triple lock. The triple lock ensures pension increases match the highest of inflation, wages, or a fixed 2.5 percent rate. A report detailing the implementation of this service is due in summer 2027. Energy support for households will include scrapping standing charges for energy supply, according to reports.

The budget announcement will occur against a backdrop of rising inflation and government borrowing, both of which hit their highest levels in a year last week. The Office for National Statistics reported that borrowing was nearly 25 billion pounds ($33 billion) in the most recent month alone. This figure was slightly higher than a year earlier due to increased spending and debt interest costs. The ONS noted that while borrowing for the financial year to September 2026 remains below the previous year's level, it is higher than the Office for Budget Responsibility's forecast.
