Autumn Budget: What It Means for UK Businesses
Last week's Autumn Budget contained a mixture of targeted support, tax changes and measures intended to provide greater certainty for businesses.
Some announcements will have a direct effect on particular sectors, while others are more relevant to longer-term planning. Below is a practical summary of what was announced, who may benefit and what businesses may want to review.
The Budget at a Glance
Business Rates
From 1 April 2027, the rateable-value threshold for 100% Small Business Rate Relief will rise from £12,000 to £18,000 for eligible retail, hospitality and leisure properties in England. Tapered relief will extend from the current £15,000 ceiling to £21,000. The Government estimates that approximately 70,000 additional businesses could become exempt as a result. A transitional package includes a two-year real-terms bill freeze for eligible businesses and a one-year extension of the 2023 Supporting Small Business scheme.
Trading Allowance
From 6 April 2027, the Income Tax Trading Allowance will increase from £1,000 to £3,000. This is a tax allowance for qualifying gross trading or miscellaneous income, not a £3,000 cash payment. It is mainly relevant to sole traders and people earning smaller amounts from side businesses or self-employment. Established limited companies do not use this allowance.
Corporation Tax
The Government reaffirmed its corporation tax roadmap rather than announcing a general reduction in the main rate. Full expensing remains available for qualifying plant and machinery. The Budget also announced changes to certain capital-allowance rates from April 2027. Companies considering substantial investment should confirm the eligible expenditure, timing and applicable allowance with their accountant before relying on the headline rates.
Energy and Employment Costs
The Budget contains targeted energy measures, but not a universal reduction in business energy bills. The British Industrial Competitiveness Scheme is aimed at eligible energy-intensive firms, while many SMEs may see little direct support. Separately, the National Living Wage is expected to rise to £13.21 an hour from April 2027 for eligible workers. Employers should confirm the final statutory rate, age eligibility and effective date when updating payroll forecasts, and should also model the effect on pension contributions and other employment costs.
Fuel and Mileage
Red diesel duty will be reduced by 3.7p per litre from 15 June 2026 until July 2027 for eligible users. From 6 April 2026, HMRC's approved mileage rate for employees using their own cars or vans for qualifying business journeys is 55p for the first 10,000 miles. The rate above 10,000 miles currently remains 25p. The Budget proposes increasing that higher-mileage rate to 35p from 6 April 2027. The approved rate is advisory: employers may reimburse more or less, but this can affect the employee's tax position. Eligibility and record-keeping rules still apply.
Tariffs and Imports
Tariffs will be suspended on 72 business products from 5 August 2026, with suspensions extended for 361 products in 2027-28. Separate packages cover 135 food products until 31 December 2028, a further 101 food products and heating-oil kerosene until the same date, and fertiliser until 31 December 2027. The cash benefit will depend on the commodity code, revised tariff rate, country of origin and volume imported. Importers should not assume that every affected product will become duty-free.
Economic Outlook
The OBR upgraded expected GDP growth for 2026 to 1.2%, but the outlook for 2027 is weaker at around 1%. Inflation is forecast at approximately 3.5% in 2027, above the Bank of England's 2% target. For businesses, modest growth may soften demand while inflation and interest rates continue to affect wages, supplier costs, margins and borrowing.
Public Finances
On the OBR's central forecast, the current-budget fiscal rule is met in 2029-30 with £15 billion of headroom, £7 billion less than at Budget 2025. The OBR estimates a 56% probability of the rule being met, so the headroom should not be interpreted as a guaranteed cash buffer. Public sector net debt is forecast to peak at around 97% of GDP in 2028-29 before easing to approximately 96% by 2031-32. The OBR also says debt interest and inflation increased pre-measures borrowing by an average of around £11 billion a year compared with its March forecast.
What the Measures Could Mean in Practice
The direct benefits are uneven. A qualifying shop, café, pub or leisure property with a rateable value between £12,000 and £18,000 may move from partial or no Small Business Rate Relief to 100% relief from April 2027. A property between £18,000 and £21,000 may receive tapered relief. By contrast, an established limited company outside the eligible sectors may see little immediate change beyond continuity on corporation tax and selected investment allowances.
The operating-cost measures should be tested against actual usage. For example, a 3.7p-per-litre duty reduction equates to £370 across 10,000 eligible litres purchased after the measure takes effect. The amount retained will depend on eligibility, supplier pricing, purchase timing and VAT treatment.
A Practical Mileage Example
As a separate illustration, 8,000 qualifying business miles produce an HMRC-approved amount of £4,400 at 55p per mile, £800 more than at the previous 45p rate. The amount actually reimbursed remains a matter for the employer, and the tax treatment depends on the payment made.
The Broad Business Reaction
The response from business organisations has been mixed. The CBI welcomed the corporation tax roadmap and support for innovative firms but said more was needed on energy, employment costs and wider Business Rates reform.
The FSB argued that support was too narrow and did not make hiring more affordable. The BCC described the approach as steady but unlikely to shift growth materially, while the IoD welcomed the absence of major surprises.
The common theme is greater stability, but limited immediate relief for many SMEs.
What Should Businesses Review Now?
Businesses do not necessarily need to make immediate changes. However, the Budget is a useful prompt to review:
- Sales assumptions, cash-flow forecasts and customer payment timing over the next 12 months.
- The effect of wage, energy, supplier and transport costs on gross margin.
- Business Rates eligibility, property costs and any planned investment or recruitment.
- The affordability and structure of existing borrowing, including available headroom.
- Sensitivity to a downside scenario, such as slower sales or customers taking longer to pay.
Your accountant or tax adviser should confirm how the detailed tax and Business Rates measures apply to your circumstances. If your wider review raises questions about cash flow, working capital or existing borrowing, we would be happy to offer an informal second opinion.
What's Next for Your Business?
The Budget does not create the same action point for every business. The sensible next step is to identify which measures are genuinely relevant, update forecasts using realistic assumptions and check that the business has enough flexibility if conditions are weaker than expected.
Our role is to help business owners understand the funding options available where working capital or borrowing forms part of that review.
