The UK’s appliance manufacturing sector faces a pivotal year as corporation tax reforms take full effect in 2026. With rising energy costs, supply chain challenges, and tight margins, tax planning for appliances manufacturers has become essential for maintaining profitability. These reforms bring both opportunities and risks—rewarding well-timed investments but penalising errors in classification or compliance. Apex Accountants partners with appliances manufacturers across the UK, offering expert guidance on corporation tax for appliances manufacturing companies, R&D claims, and capital allowance planning. Our goal is to help businesses make informed investment decisions, manage tax efficiently, and maintain strong cash flow in an evolving financial environment.
This article highlights the key corporation tax changes for 2026, focusing on tax rates, capital allowances, R&D incentives, and compliance strategies that can help appliances manufacturers reduce liabilities and plan confidently for the future.
Corporation Tax Rates from 2026
The current corporation tax rate framework, introduced in April 2023, continues into 2026. Appliance manufacturers should plan using the following thresholds:
- Main rate: 25% for companies with taxable profits above £250,000.
- Small profit rate: 19% for profits up to £50,000.
- Marginal Relief: Applies between £50,000 and £250,000, providing a gradual increase in the effective rate.
- Associated companies: If your company has subsidiaries or related entities, the thresholds reduce proportionally, potentially bringing you into the higher tax band earlier.
Manufacturers must assess their group structure carefully and forecast profits to determine their expected effective tax rate.

Capital Allowances and Investment Incentives
Full Expensing for Plant and Machinery
Introduced in April 2023 and now made permanent, Full Expensing allows 100% tax relief in the year of purchase for qualifying new and unused main-rate plant and machinery. This includes production equipment, robotic systems, and assembly lines.
Key points:
- Applies only to new and unused assets.
- Leased or second-hand machinery does not qualify.
- Expenditure must be incurred, and the asset must be in use within the accounting period.
Special Rate Assets
Certain items, such as integral features of buildings (heating, lighting, or ventilation systems), qualify for a 50% first-year allowance, with the remaining balance written down in subsequent years.
Annual Investment Allowance (AIA)
The AIA limit remains at £1 million per year. It allows 100% deduction for most qualifying assets, including second-hand equipment. For manufacturers combining full expensing and AIA, it is vital to allocate expenditures correctly to maximise overall benefit.
Research and Development (R&D) Changes
From 2024, the UK introduced a merged R&D scheme for all companies. In 2026, appliances manufacturers conducting qualifying R&D activities—such as developing energy-efficient appliances, new materials, or automation processes—can continue to claim:
- A taxable expenditure credit for qualifying R&D costs.
- The credit is treated as taxable income, providing a meaningful reduction in the overall tax burden for profit-making companies.
- R&D-intensive SMEs with significant qualifying expenditure can still access enhanced cash benefits.
Maintaining accurate technical documentation and cost records is essential to defend R&D claims during HMRC reviews. Effective corporation tax advice for manufacturing businesses can help identify eligible projects and avoid compliance risks.
Global Minimum Tax and Pillar Two
Large UK appliances manufacturers that are part of multinational groups with global revenues exceeding £651.72 million will fall under the OECD’s Pillar Two framework. This introduces a minimum 15% effective tax rate per jurisdiction. UK groups meeting this threshold must perform effective tax rate calculations and prepare for top-up taxes from 2026 onwards.
Key Risks for Appliances Manufacturers
- Incorrect asset classification – Misidentifying special-rate assets can reduce tax savings.
- Leased or used machinery – Incorrectly claiming full expensing on ineligible assets can trigger HMRC penalties.
- Associated company issues – Failing to account for group links may lead to unexpected higher tax rates.
- R&D claim errors – Poor documentation or weak technical justification may cause HMRC rejections.
- Timing mismatches – Delays in placing machinery into use can defer deductions into future years.
Opportunities for 2026 Planning
- Schedule major equipment purchases to coincide with profitable periods to gain maximum deduction.
- Use AIA for assets excluded from full expensing.
- Integrate R&D tax planning into product development cycles.
- Conduct early tax modelling to estimate post-reform liabilities.
- Maintain robust records of asset costs, commissioning dates, and supplier invoices.
Case Study: Apex Accountants Supporting a UK Appliances Manufacturer
A mid-sized UK appliances manufacturer approached Apex Accountants in 2025 ahead of its factory expansion project. The business planned to invest £3.2 million in new robotic assembly lines and energy-efficient systems. Our team performed a detailed capital allowance review and identified that:
- £2.4 million qualified for full expensing as new and unused main-rate assets.
- £600,000 of integral features, such as lighting and ventilation, qualified for the 50% special-rate allowance.
- The remaining £200,000 of second-hand tooling was allocated under the Annual Investment Allowance (AIA).
We also conducted an R&D assessment, identifying qualifying projects related to sensor innovation and energy efficiency. This produced an R&D expenditure credit worth £180,000, improving overall tax efficiency.
As a result, the client reduced its 2025–26 tax liability by nearly £800,000, freeing cash for new product development and workforce expansion.
