LONDON — The wait is finally over. After weeks of briefings, speculation, and U-turns, Chancellor Rachel Reeves has set out her final tax and spending plans for the year ahead.

As expected, there is plenty for policy wonks to chew over. To make your lives easier, we’ve digested the headline budget announcements on energy, financial services, tech, and trade, and dug deep into the documents for things you might have missed. 

Energy 

The government really wants to bring down bills: Rachel Reeves promised it would be a cost-of-living budget, and surprised no one with a big pledge on families’ sky-high energy bills. She unveiled reforms which, the Treasury claims, will cut bills by £150 a year — by scrapping one green scheme currently paid for through bills (the Energy Company Obligation) and moving most of another into general taxation (the Renewables Obligation). The problem is, the changes will kick in next year at the same time bills are set to rise anyway. So will voters actually notice?

The North Sea hasn’t escaped its taxes: Fossil fuel lobbyists were desperate to see a cut in the so-called Windfall Tax, which, oil and gas firms say, limits investment and jobs in the North Sea. But Rachel Reeves ultimately decided to keep the tax in place until 2030 (even if North Sea firms did get a sop through rules announced today, which will allow them to explore for new oil and gas in areas linked to existing, licensed sites.) Fossil fuel lobbyists, Offshore Energies UK, were very unimpressed. “The government was warned of the dangers of inaction. They must now own the consequences and reconsider,” it said.

Financial services

Pension tax changes won’t arrive for some time: The widely expected cut in tax breaks for pension salary sacrifice is set to go ahead, but it will be implemented far later than thought. The thresholds for exemption from national insurance taxes on salary sacrifice contributions will be lowered from £60,000 to £2,000 in April 2029, likely to improve forecasts for deficit cuts in the later years of the OBR’s forecasts.

The OBR has a markets warning: The U.K.’s fiscal watchdog warned that the price-to-earnings ratio among U.S. equities is reminiscent of the dotcom bubble and post-pandemic rally in 2021, which were both followed by significant market crashes. The OBR estimated a global stock market collapse could cause a £121 billion hike in U.K. government debt by 2030 and slash U.K. growth by 0.6 percent in 2027-28. Even if the U.K. managed to stay isolated from the equity collapse, the OBR reckons the government would still incur £61 billion in Public Sector Net Financial Liabilities.

Banks back British investments: British banks and investment houses have signed an agreement with the Treasury to create “invest in Britain” hubs to boost retail investment in U.K. stocks, a plan revealed by POLITICO last week. Reeves also finally tabled a cut to the tax-free cash ISA allowance: £12,000 from spring 2027 (the amount and timings also revealed by POLITICO last week), down from £20,000, with £8,000 slated for investments only. Over-65s will keep the full tax-free subscription amount. Also hidden in the documents was an upcoming consultation to replace the lifetime ISA with a “new, simpler ISA product to support first-time buyers to buy a home.”

No bank tax: Banks managed to dodge a hike in their taxes this time, despite calls from the IPPR for a windfall-style tax that could have raised £8 billion. The suggestions (which also came from inside the Labour Party) were met with an intense lobbying effort from the banks, both publicly and privately. By the eve of the budget, City figures told POLITICO they were confident taxes wouldn’t be raised, citing the high rate of tax they already pay and Reeves’ commitment to pushing for growth through the financial services industry.

Tech

‘Start, scale, stay’ is the new mantra:  Startup founders and investors were in panic mode ahead of the budget over rumored plans for an “exit tax” on wealthy individuals moving abroad, but instead were handed several wins on Wednesday, with Reeves saying her aim was to “make Britain the best place in the world to start up, to scale up and to stay.” She announced an increase in limits for the Enterprise Manage Scheme, which incentivizes granting employees share options, and an increase to Venture Capital Trust (VCT) and Enterprise Investment Scheme (EIS) thresholds to facilitate investment in growing startups. A further call for evidence will also consider “how our tax system can better back entrepreneurs,” Reeves announced. The government will also consider banning non-compete clauses — another long-standing request from startups.

Big Tech will still have to cough up: A long-standing commitment to review a Digital Services Tax on tech giants was quietly published alongside the budget, confirming it will remain in place despite pressure from the Trump administration.

The government will ‘Buy British’ on AI: Most of the government’s AI announcements came ahead of the budget — including plans for two new “AI Growth Zones” in Wales, an expansion of publicly owned compute infrastructure — meaning the only new announcements on the day were a relatively minor “digital adoption package” and a commitment to overhaul procurement processes to benefit innovative tech firms. But the real point of interest on AI came in the OBR’s productivity forecasts, which said that despite the furor over AI, the technology’s impacts on productivity would be smaller than previous waves of technology, providing just a 0.2 percentage point boost by 2030.

OBR delivers a blow to digital ID: The OBR threw up another curveball, estimating the cost of the government’s digital ID scheme at a whopping £1.8 billion over the next three years and calling out the government for making “no explicit provision” for the expense. The government insists digital ID will ultimately lead to cost savings — but “no specific savings have yet been identified,” the OBR added.

Trade 

Shein and Temu face new fees: In a move targeted at online retailers like Shein and Temu, the government launched a consultation on scrapping the de minimis customs loophole, which exempts shipments worth less than £135 from import duties. These changes will take effect from March 2029 “at the latest,” according to a consultation document. Businesses are being consulted on how the tariff should be applied, what data to collect, whether to apply an additional administration fee, as well as potential changes to VAT collection. Reeves said the plans would “support a level-playing field in retail” by stopping online firms from “undercutting our High Street businesses.” 

Northern Irish traders get extra support: Also confirmed in the budget is £16.6 million over three years to create a “one-stop shop” support service to help firms in Northern Ireland navigate post-Brexit trading rules. The government said the funding would “unlock opportunities” for trading across the U.K. internal market and encourage Northern Ireland to take advantage of access to EU markets. 

There’s a big question mark over drug spending: Conspicuously absent was any mention of NHS drug spending, despite U.K. proposals to raise the cost-effectiveness threshold for new drugs by 25 percent as part of trade negotiations with the U.S., suggesting a deal has not yet been finalized. The lack of funding was noted as a potential risk to health spending in the Office for Budget Responsibility’s Economic and Fiscal Outlook, which was leaked ahead of the budget.
