UK Businesses Face Fresh Energy Price Shock as Calls Grow for Long-Term Strategy

British businesses are bracing for another surge in energy costs, compounding an already difficult operating environment. Even before the latest geopolitical tensions pushed global prices higher, the UK had the highest industrial electricity costs among G7 nations—raising renewed questions about the country’s long-term energy and industrial strategy.

Rising Energy Costs Add Pressure on UK Firms

The latest projections from consultancy Cornwall Insight point to sharp increases in both electricity and gas prices for businesses.

Electricity costs could rise by between 10% and 30%, while gas prices may jump by as much as 25% to 80%. Unlike households, UK businesses are not protected by an energy price cap, meaning costs are determined through contracts negotiated directly with suppliers.

This leaves companies exposed to market volatility, with pricing influenced by factors such as company size, sector, energy consumption and financial stability.

Real-World Impact on Bills

Cornwall Insight highlights the scale of the potential increases. A larger retail or leisure site—or a small manufacturing business—could see its annual electricity contract rise to around £578,000, an increase of roughly £95,000 in just a matter of weeks.

Gas bills are set to climb even more steeply, potentially increasing by £376,000 to exceed £1 million annually.

For many firms already grappling with inflationary pressures, wage demands and supply chain disruptions, such increases could significantly erode margins.

Timing and Market Volatility Intensify the Challenge

The timing of the latest price spike is particularly problematic. Around one-third of UK businesses renew their energy contracts at the start of April, aligning with the beginning of the financial year. This means higher wholesale prices are passed through almost immediately.

Compounding the issue is extreme market volatility. Prices are fluctuating rapidly—even within a single day—making it difficult for businesses to secure stable contracts.

Adam Berman, director of policy and advocacy at EnergyUK, described a highly unstable market environment. Suppliers are increasingly reluctant to offer long-term deals, and in some cases, quotes are withdrawn within hours due to shifting prices.

As a result, some companies are opting for short-term contracts of just three months, rather than the more typical annual agreements, in an attempt to manage uncertainty.

Limited Scope for Government Intervention

In the short term, there appears to be little prospect of broad government support for businesses facing rising energy costs.

Chancellor Rachel Reeves has signalled that any future assistance is likely to be targeted at vulnerable households rather than companies. Given the current fiscal constraints, a wide-ranging support package for businesses is considered unlikely.

Industrial Support Schemes in Limbo

There is some possibility—albeit remote—that planned support for energy-intensive industries could be accelerated.

A proposed “British industrial competitiveness scheme”, which aims to deliver energy bill reductions of up to 25% for around 7,000 manufacturing firms from April next year, remains under development. However, progress has been slow, with ongoing debates over eligibility criteria and funding.

Meanwhile, the existing “supercharger” scheme, which provides discounts for heavy energy users, will expand slightly from next month—but it currently covers only around 500 companies.

Economic Growth Slows Amid Cost Pressures

The broader economic picture reflects the strain. Recent purchasing managers’ index (PMI) data suggests UK growth has slowed “to a crawl” across both manufacturing and services.

Cost inflation has accelerated at its fastest monthly rate since the period following the Black Wednesday, underlining the severity of current pressures.

Energy costs, in particular, are transmitted rapidly through the economy, affecting everything from production to pricing.

Long-Term Energy Strategy Back in Focus

While immediate relief may be limited, the latest energy shock has reignited debate over the UK’s long-term approach to energy policy and industrial competitiveness.

Business groups, including the Confederation of British Industry and EnergyUK, have argued that persistently high energy costs are undermining economic growth.

Their central claim—that expensive energy is holding back UK industry—has gained renewed urgency in light of recent developments.

A Need for Structural Reform

Analysts suggest that short-term support measures funded by other bill payers are not a sustainable solution. Instead, a more strategic, long-term reset of energy policy is required—one that addresses structural cost issues and improves resilience to global shocks.

Other advanced economies, including European neighbours, are often cited as examples of more coordinated and strategic approaches to energy pricing and industrial policy.

Conclusion

The latest surge in energy costs is another setback for UK businesses already operating under significant pressure. While immediate government intervention appears unlikely, the crisis has sharpened calls for a comprehensive rethink of energy strategy. Without structural reform, high energy prices risk continuing to weigh on competitiveness, investment and long-term economic growth.
