UK Debt Hits Record £3 Trillion as Burnham Faces First Budget Test

Andy Burnham’s new administration faces its first major test this Wednesday, with Chancellor John Healey taking the floor at 12:30 GMT to unveil the autumn budget. It is a high-stakes moment. The UK is grappling with soaring living costs, and energy bills are set for their steepest jump in four years come January, driven largely by the ongoing conflict in the Middle East.

The financial backdrop is grim. Total UK borrowing smashed through the 3 trillion pounds ($3.99 trillion) mark for the first time in September. The cost of servicing that debt now runs at 100 billion pounds ($133bn) annually. Still, Healey promised to shift "money and power out of Westminster and into every postcode around Britain." In a recent speech, he claimed he and Burnham are working in "lockstep" to balance the books, maintain buffers against uncertainty, and control borrowing to crush inflation.

Expect a different tone from previous budgets. After two fiscal statements under former Chancellor Rachel Reeves that packed in significant tax hikes and spending increases, Healey is reportedly adopting a "steady as she goes" approach. Critics argue that caution is the wrong strategy right now.

Defence spending will likely dominate the headlines. On Monday, Burnham told ITV’s Good Morning Britain that his government's primary challenge is financing the already announced defence investment plan. That plan, launched in June, backs 298 billion pounds ($396bn) of investment to transform the armed forces for "warfighting readiness" and bolster "European security."

Burnham stressed the importance of having a funded plan they can actually implement. "We will set out more details on Wednesday as to how we've done that," he said. The roadmap includes meeting NATO commitments to spend 3 percent of gross domestic product (GDP) on defence by 2030 and 3.5 percent by 2035. Currently, Britain spends about 2.6 percent of its GDP on defence.

The Guardian reports Healey aims to close a 4.7-billion-pound ($6.2bn) funding gap in the inherited Labour Party plan. Cuts to other departmental budgets are the likely source of those funds.

Inflation remains a stubborn problem. Last week, both UK inflation and government borrowing hit their highest levels in a year. The Office for National Statistics (ONS) reported borrowing of nearly 25 billion pounds ($33bn) last month alone. That figure was slightly higher than a year earlier because spending, including rising debt interest costs, outpaced government income.

The ONS noted that while borrowing in the financial year to September 2026 stayed below the same period last year, it exceeded the Office for Budget Responsibility’s forecast. Debt at the end of last month exceeded 3 trillion pounds ($3.99 trillion). Much of this surge stems from the Iran war and the fallout from the closure of the Strait of Hormuz, which forced the government to borrow more than expected.

Jasper Kanter, a professorial research fellow in ecological economics at Aberystwyth Business School, argues that growing the economy without spiking inflation requires a deeper understanding of what kind of economy is being built.

"The strongest policies improve prosperity, resilience and sustainability at the same time," Kanter said. He added that growth is less likely to be inflationary when it comes from increasing the economy’s productive capacity rather than simply boosting spending.

Chancellor Rachel Reeves faces a tightrope walk. She must balance fiscal discipline against rising costs.

Helen Miller, director of the Institute for Fiscal Studies, warns that a "steady-as-she-goes" approach is not an option. Her media release notes that borrowing is expected to fall, yet inflation threatens to derail departmental spending plans.

"Choosing to stay the course with the inherited tax and spending plans would mean allowing inflation to blow departments’ spending plans off course," Miller said.

The budget will likely target the financial sector. New taxes on banks and online marketplaces are on the horizon. Amazon, Temu, and eBay are in the crosshairs.

The biggest four banks made about £15 billion ($19.9bn) in profit during the first half of this year. Trade unions want more tax on those earnings. The Treasury is reportedly leaning toward adjusting a 2023 surcharge rate. That change could raise about £2 billion ($2.6bn).

Online sellers face scrutiny too. Healey aims to crack down on foreign vendors avoiding UK VAT. This measure could generate as much as £1 billion ($1.3bn). The revenue would help fund business rate cuts for high street shops.

Public spending is massive. According to The Guardian, day-to-day spending and public investment will total about £1.42 trillion ($1.8 trillion) this year. Debt interest alone will consume about £100 billion ($132.8bn).

Kanter, of Aberystwyth Business School, expects "targeted support rather than large-scale tax cuts or rises." He believes the government wants to signal empathy for people under pressure.

"Addressing the harsh cliff edge in carer’s allowance and expanding parental pay are good examples of this," Kanter told Al Jazeera.

Some measures are already locked in. The cap on carers’ allowance ends. Tariffs on chocolate and beans drop to lower prices for shoppers.

Pensioners get a shield. A new personal allowance will protect them from income tax. Healey is also expected to add another £1 billion ($1.3bn) to the £39 billion ($51.8bn) planned for social and affordable housing in England over the next decade.

"Pensioners will benefit from another substantial increase in the state pension, while low-paid workers will benefit from increases in the minimum wage," Kanter explained. "For most households, the bigger determinants of living standards will remain wages, inflation and energy costs rather than any new tax measures announced in the budget."

Last month, Andy Burnham announced a new national care service. It will provide free personal care for elderly people.

Measures that improve skills, reduce energy dependence, strengthen local economies, and regenerate ecosystems are likely to deliver more lasting benefits than short-term stimulus.

Elderly care costs have rocketed across the UK, making this a headline concern since Burnham took office. He insists the new plan will roll out in stages, paid for entirely by public spending and savings from ditching the state pension triple lock. For context, that lock guarantees annual rises tied to inflation, wages, or a fixed 2.5 percent, whichever is higher. A detailed report on implementation is due by summer 2027.

Energy bills are another bleeding point. The US-Israeli conflict with Iran and the resulting closure of the Strait of Hormuz have sent gas and oil prices spiraling. Brent crude futures hit $115.90 a barrel on Wednesday. Domestic households feel the pinch. Cornwall Insight, in its latest forecast from last month, predicts UK energy prices will climb by 16 percent. That puts annual bills near 2,000 pounds ($2,655) starting in January.

What happens next? Reports indicate the chancellor plans to announce relief measures in the upcoming budget. Scrapping standing charges for energy supply is expected to be a key part of the package.
