Investment has to make commercial sense
Aaron Blutstein 23 September 2026 
As the Chancellor prepares the Autumn Budget, manufacturers could be forgiven for being less interested in the language surrounding growth than in the conditions needed to deliver it. Most engineering businesses do not need persuading of the case for investing in new machinery, automation, energy efficiency or people; the harder question is whether, against the current backdrop of costs and uncertainty, the sums justify doing it now.
The UK already provides significant tax relief for investment in plant and machinery, through full expensing for qualifying company expenditure and the £1 million Annual Investment Allowance, among other allowances. The priority should therefore be to give manufacturers some confidence that the investment environment will remain stable rather than subjecting it to repeated changes. Tax treatment matters, but even generous allowances will not turn a proposed investment into a purchase order when energy and employment costs are high, order books are uncertain and businesses are reluctant to commit capital.
Investment is important throughout manufacturing, not only for increasing capacity but for improving productivity, efficiency and competitiveness. For many businesses, the decision is whether to replace ageing equipment, automate a process, improve an existing production line or continue to get by with what they already have. When confidence is fragile, it is often these projects that are delayed, with consequences that extend through the engineering supply chain.
There is a similar connection with energy policy, as manufacturers have considerable scope to reduce consumption through more efficient machinery, better controls, improved monitoring and changes to production processes. These are practical engineering improvements that can deliver measurable returns, but the initial investment still has to compete for capital with everything else a business needs to fund. High industrial energy costs also make it harder for UK manufacturers to compete, even while giving them a greater incentive to improve efficiency.
Manufacturing itself is changing as sensors, automation, condition monitoring, data and connected systems become more commonplace on the factory floor. Programmes such as Made Smarter can help SMEs adopt these technologies, but support needs to be straightforward enough for smaller manufacturers to use and sufficiently practical to result in equipment being installed and productivity improved rather than another digital strategy being written.
Skills form part of the same picture, with engineers and technicians increasingly needing to work across traditional mechanical disciplines, electronics, controls, software and data. Training and apprenticeship policy needs to reflect what modern manufacturing actually requires and make it easier for employers to develop those capabilities.
No Budget can remove every uncertainty facing manufacturers, but this one can provide greater stability and address some of the costs holding investment back. The test is ultimately a practical one: does it give UK manufacturers greater confidence to invest and sign the next purchase order?
