Britain’s manufacturers are warning that high energy costs are putting jobs, investment and industrial capacity at risk, with a growing number of firms either moving production overseas or actively considering doing so.
The warning comes amid renewed concern that the UK’s industrial electricity prices remain among the highest in the developed world, leaving manufacturers at a competitive disadvantage against rivals in Europe, the United States and Asia.
Energy-intensive sectors such as steel, chemicals, ceramics, glass, cement, paper, food production and foundries are under particular pressure. These businesses depend on large amounts of electricity and gas, meaning energy prices are not a marginal issue. They are central to whether production in the UK remains commercially viable.
For manufacturers already dealing with labour costs, supply chain disruption, interest rates, taxation, regulation and weak domestic demand, energy has become one of the clearest threats to competitiveness.
A growing offshoring risk
The latest concerns follow warnings from Make UK and the Trades Union Congress that Britain could face a wave of deindustrialisation unless manufacturers receive more urgent relief from high electricity prices.
Recent survey evidence suggests that a quarter of manufacturers have either moved some production overseas or are considering doing so. Almost four in ten have delayed investment, while more than a fifth have reduced headcount.
For a sector that employs millions of people directly and indirectly, those figures are significant. Manufacturing jobs are often concentrated in regions where well-paid industrial work supports local supply chains, training routes and community employment.
The risk is not only that factories close. It is that future investment goes elsewhere.
Once production lines, supplier relationships and skilled teams are lost, they are difficult to recreate. A company that decides to build its next plant in mainland Europe, the US or Asia may not reverse that decision simply because UK policy improves later.
That is why manufacturers describe the issue as urgent. The concern is not theoretical. It is about decisions being made now on where to invest, where to hire and where to produce.
Why UK energy prices are so high
The causes of the UK’s high industrial energy costs are complex.
One issue is the UK’s reliance on gas-fired power stations to balance the electricity system. Under marginal pricing, the most expensive source of power needed to meet demand often sets the wholesale electricity price. Because gas plants are frequently required, gas prices can have an outsized effect on electricity prices even when a growing share of power is generated by renewables.
That has mattered since Russia’s invasion of Ukraine in 2022, which caused a major energy shock across Europe. It has also mattered again during the latest Middle East tensions, which have contributed to volatility in oil and gas markets.
Another issue is the structure of bills. Industrial electricity users face not only wholesale energy costs, but also network charges, policy costs and levies linked to the wider energy system. Manufacturers argue that these costs fall too heavily on electricity users and make the UK less attractive for investment.
There is also the question of infrastructure. Britain needs major grid investment to connect renewables, reinforce transmission networks and support electrification. In the long term, that could reduce reliance on fossil fuel imports and improve energy security. In the short term, however, the cost of upgrading the system can add to bills.
This creates a difficult transition problem. The UK wants cleaner, more secure and more domestic energy. But the journey to that system is currently expensive for many businesses.
The government’s response
The government has recognised the problem and has introduced targeted support for energy-intensive industries.
The British Industry Supercharger and related schemes are designed to reduce electricity costs for qualifying businesses by cutting or compensating some network and policy costs. The Network Charging Compensation Scheme has also been increased from 60% to 90% for eligible energy-intensive industries, taking effect from April 2026, although compensation is paid in arrears.
Ministers argue that this support forms part of a wider modern industrial strategy designed to improve competitiveness, support investment and protect strategically important sectors.
The government position is that manufacturing is vital to economic growth and that high energy costs are being addressed through targeted relief, clean power investment and reforms to the energy system.
However, industry groups argue that current support is still too narrow, too slow or too limited. Some manufacturers do not qualify. Others may qualify but will not receive cash support quickly enough to ease immediate pressure. Smaller firms in supply chains may also face high energy costs without benefiting from the most generous relief schemes.
That is where the dispute lies. The government says it is acting. Manufacturers say the action does not yet match the scale of the problem.
A broader industrial strategy question
The debate goes far beyond electricity bills.
Britain has repeatedly said it wants to rebuild industrial strength, increase domestic resilience, support advanced manufacturing and grow sectors such as clean technology, defence, automotive, aerospace, life sciences and green infrastructure.
But those ambitions depend on competitive input costs.
A country cannot easily present itself as a manufacturing hub if industrial power costs are persistently higher than those faced by competitors. Businesses may admire the UK’s skills base, legal system, research universities and innovation ecosystem, but final investment decisions often come down to cost, reliability and policy certainty.
This is particularly important for energy-intensive industries. A glass furnace, chemical plant or steel works cannot simply absorb high electricity and gas costs indefinitely. If margins are squeezed for long enough, the choice becomes raising prices, cutting investment, reducing jobs or moving production.
That also affects the transition to net zero. Many green technologies require manufacturing capacity. Wind turbines, electric vehicle components, heat pumps, batteries, grid equipment and low-carbon construction materials all need industrial supply chains. If the UK loses too much manufacturing capacity, it risks becoming more dependent on imports for the very transition it is trying to deliver.
The consumer impact
High industrial energy costs do not only affect factory owners.
They can feed into prices across the economy. Manufacturers facing higher electricity, gas, transport and materials costs may pass those increases on to customers. That can affect everything from food packaging and building materials to cars, household goods and infrastructure projects.
There is already evidence that manufacturers have been raising prices in response to higher input costs. For the Bank of England, this matters because energy-driven cost increases can spill over into broader inflation.
If companies absorb the costs, profits fall and investment weakens. If they pass the costs on, inflationary pressure rises. Neither outcome is ideal.
This is why industrial energy policy is also economic policy. It affects inflation, productivity, investment, exports, regional growth and living standards.
The case for caution
There is, however, another side to the debate.
Large-scale subsidies or shifting levies from business bills to general taxation would cost money. At a time when the public finances are already under pressure, ministers must decide whether support for manufacturers should take priority over other demands such as defence, welfare, public services and household support.
There is also a fairness question. If some industrial users receive relief, other businesses or taxpayers may end up bearing more of the cost. Retailers, hospitality businesses and smaller service firms also face high energy bills, but may not qualify for industrial schemes.
Policy also needs to avoid locking in inefficient energy use. Support should protect viable businesses and strategic capacity, but it should not remove incentives to invest in efficiency, electrification, storage, demand flexibility and low-carbon technologies.
That makes the solution more complicated than simply cutting bills. The challenge is to reduce the UK’s structural cost disadvantage while still encouraging energy efficiency and long-term system reform.
What businesses need now
For manufacturers, the immediate priority is certainty.
Businesses need to know what support will be available, when it will arrive, whether they qualify and how long it will last. Investment decisions cannot be based on temporary announcements, delayed compensation or schemes that may change after the next fiscal event.
They also need clarity on the direction of the electricity market. If the government intends to reform marginal pricing, rebalance levies, expand industrial support or accelerate grid investment, businesses need a credible timetable.
For many firms, the issue is not whether the UK can eventually build a cleaner and cheaper energy system. The issue is whether they can survive long enough to benefit from it.
A warning sign for the UK economy
The renewed focus on manufacturing energy costs is a warning sign for the wider economy.
Britain has spent years discussing productivity, growth, levelling up, exports and industrial renewal. Yet high energy costs cut across all of those ambitions. They reduce margins, weaken investment, threaten jobs and make the UK a harder place to manufacture.
There is no simple solution. The government must balance support for industry against fiscal constraints, climate goals and fairness to other consumers. But ignoring the problem would carry its own cost.
If production moves overseas, the UK loses more than output. It loses skills, supply chains, tax revenue, regional employment and strategic capability.
The immediate energy shock may eventually ease. The deeper question is whether Britain can build an energy system that is not only cleaner, but also affordable and competitive for industry.
For now, manufacturers are sending a clear message: unless the cost gap is closed, more investment will go elsewhere.
