Chancellor John Healey Faces Budget Squeeze As Headroom Drops
The UK government faces a shrinking cash buffer ahead of the upcoming Budget as rising borrowing costs pressure public finances. Chancellor John Healey must decide how to raise funds to meet fiscal rules without breaking Labour’s 2024 election manifesto pledges.
Rising Interest Rates Squeeze Budget Headroom
Chancellor John Healey enters the upcoming Budget facing a significant squeeze on public finances, according to BBC reporting. Economists estimate that the government’s cash buffer—known as headroom—might have halved over the last six months, dropping from approximately £24bn down to £11bn. This decline stems partly from rising interest rates that the government pays to borrow money from private investors.
The Chancellor needs to restore this buffer to demonstrate that Labour’s plan to reduce borrowing by the end of the Parliament remains on track. Concurrently, the Treasury deals with heavy demands to secure funds for military expenditures and to assist citizens dealing with escalating living expenses.
However, Labour’s 2024 election manifesto explicitly pledged not to raise the rates of income tax, VAT, or National Insurance. While increasing taxes on capital gains or extending the mansion tax had previously been raised as possible options, government sources have since ruled them out.

Potential Tax Adjustments for Banks and Gambling Machines
With traditional tax levers restricted by manifesto commitments, BBC Verify reports that policymakers are evaluating alternative revenue streams ahead of Wednesday’s announcement.
One primary option involves increasing taxes on banks. UK banks have seen profits rise in recent years by charging higher interest rates on borrowing. Projections by the Tax Policy Associates think tank indicate that the Treasury could generate between £1bn and £2bn each year by bumping the corporation tax surcharge on banks from 3% to 5.5%. Bank bosses warn that additional taxes could deter investment, reduce jobs, and indirectly impact ordinary savers through pension funds or higher borrowing costs.

Former prime minister Gordon Brown has urged the Chancellor to hike taxes on electronic gaming machines in betting shops and adult gaming centres, citing social harm from problem gambling. The Social Market Foundation (SMF) estimates that doubling the tax on these machines from 20% to 40% could raise between £275m and £460m. The gambling industry argues that such a tax hike could force betting shop closures, threatening jobs and reducing financial contributions to horse racing.
Online Marketplaces May Collect VAT for Retailers
Another major revenue proposal targets major digital platforms. Reports indicate the Chancellor is preparing to make online marketplaces such as Amazon, eBay, and Temu legally responsible for collecting tax owed by third-party retailers selling on their sites.
The Treasury estimates it misses out on approximately £12bn a year in VAT revenues that should be paid by companies operating online, a shortfall known as the VAT tax gap. Tax experts note that while third-party non-compliance does not account for the entirety of the £12bn gap, shifting collection duties to platforms represents a direct method to capture uncollected revenue without altering consumer tax rates.
Economists expect the Chancellor’s decisions on Wednesday to show whether the plan to reduce borrowing by the end of the Parliament is still on track.
