The UK steel fantasy: Why supply-side thinking keeps failing and an industrial opportunity for Scotland

AS A DOCTOR I have been taught that evidence is core to practice. As a child of the 1980s, Adam Ant taught me something else. In the words of Prince Charming, ridicule is nothing to be scared of. Finally my thoughts turn to my old friend at Sheffield medical school, who is an incorrigible fan of Cshipardiff City FC. Oh how I have suffered. Give the man one beer, and you will hear about Cardiff City all night long. I certainly have.

So, my ears have pricked up because some party on the right has decided to talk again about the steel industry – one I know well from my Sheffield days. I must stress: ridicule is nothing to be scared of – and the right really has to stop talking about industry in the detached, ethereal way it usually does. Instead, we need evidence and sector-informed vision about where the UK can go in steel making.

A serious UK steel strategy has to begin with an uncomfortable but necessary truth: Britain does not have a natural demand base for bulk steel anymore, and pretending otherwise leads to policy that props up structure rather than purpose. Steel industries do not exist in isolation – they exist because there is sustained downstream demand from manufacturing, shipbuilding, automotive production, appliances, and large-scale construction. When that demand erodes, steel production does not lead it; it follows it downward.

Historically, the UK steel industry grew because there was a dense industrial ecosystem to serve. Shipyards, railways, heavy engineering firms, domestic car manufacturing, appliance production, and large infrastructure projects created a continuous pull for large volumes of steel. Steel was not the starting point of industrial strength – it was the response to it. When that ecosystem contracted, steel did not disappear immediately; it lingered at the margins, increasingly reliant on exports and state support, until global competition and energy costs made it structurally uncompetitive.

The sequencing matters. The UK lost shipbuilding scale before it lost steelmaking capacity. Once shipyards declined, one of the most steel-intensive domestic industries disappeared. As export competitiveness weakened at the margin, steel producers lost the ability to compensate for shrinking domestic demand. Steel mills were not the first domino – they were the last.

This exposes a core misunderstanding in modern policy debates: you do not rebuild steel demand by subsidising steel supply. You rebuild steel supply by rebuilding the industries that use it. Without that, you are sustaining production into an artificial market rather than a real one.

Today, the UK simply does not generate large-scale domestic demand for bulk steel in the way it once did. We do not build ships at global scale. We do not manufacture mass-market vehicles at the same intensity. We do not produce domestic appliances – fridges, washing machines – at a scale that would anchor heavy steel consumption. Much of our construction supply chain is globalised. The UK is no longer a high-volume manufacturing economy, and steel policy must reflect that reality.

Where demand does exist is in high-value, not high-volume segments. The UK still has strong structural demand for high-performance alloys, aerospace and turbine-grade materials, defence applications, precision engineering steel and structural steel for infrastructure and specialised construction. These are specification-driven products where value lies in performance, not tonnage. This is where the UK can still compete.

That leads to a more fundamental reframing: steel production should not be treated as the foundation of industrial strategy. It should be treated as a downstream capability embedded within a broader manufacturing ecosystem. The correct sequence is not “build steel mills to support industry”. It is “build competitive manufacturing systems, and let steel production form around them”.

This inversion matters because much current debate still assumes that maintaining steel capacity will somehow recreate industrial demand. It will not. Without shipbuilding, large-scale automotive production, appliance manufacturing, and heavy engineering at volume, there is no anchor for bulk steel production.

blast furnaces are rigid, capital-intensive systems optimised for a world that no longer exists in the UK

This is also why attempts to preserve blast furnace capacity are increasingly disconnected from economic reality. Blast furnaces are designed for continuous, high-volume output into stable demand. They depend on imported iron ore and coking coal, stable energy, and uninterrupted logistics. They are not flexible assets – they are rigid, capital-intensive systems optimised for a world that no longer exists in the UK.

The historical investment pattern reinforces this point. Across Europe and the UK, genuinely new blast furnace construction effectively stopped in the early 2000s. For over two decades, there has been no meaningful expansion of blast furnace capacity. What has happened instead is periodic relining and rebuilding of existing furnaces – extending their life by ten to twenty years, improving efficiency, but not creating new capacity.

This distinction is critical. Rebuilding a furnace is not the same as choosing that technology for the future. It is a maintenance decision, not a strategic one. And over the last decade, even that pattern has begun to shift. Instead of relining blast furnaces, companies are increasingly choosing to close them and replace them with electric arc furnaces or alternative technologies.

In other words, the industry itself has already made the decision: blast furnaces belong to the past, not the future.

Even in scenarios of geopolitical disruption, their strategic value is questionable. Blast furnaces are highly vulnerable to supply chain shocks. They rely on continuous inputs of imported raw materials and cannot be easily paused or restarted. In a crisis – whether war, blockade, or energy shock – they do not degrade gradually. They fail quickly.

The idea that they represent resilience is therefore largely an illusion.

By contrast, electric arc furnace systems – based on scrap steel – are far more adaptable. They can operate intermittently, scale output, restart quickly, and rely on domestic material flows. The UK already exports large volumes of scrap steel, effectively shipping industrial value abroad. Retaining and upgrading that scrap into high-quality steel domestically is a far more realistic strategic foundation.

Energy is the second pivot. The UK’s renewable system, particularly wind, creates a unique opportunity. At times of low demand, large amounts of electricity are curtailed. Electric steelmaking is one of the few industrial processes capable of absorbing that surplus. This creates a pathway for coupling steel production with otherwise wasted energy.

This is where Scotland becomes strategically central. Scotland’s wind resources – especially offshore – generate significant surplus electricity at times. Combined with engineering capability and industrial heritage, this creates the basis for a new kind of steel cluster: one built on renewable energy, flexible production, and high-value output.

This is not about recreating bulk steel production. It is about building a modern, energy-integrated metallurgy system.

There is also growing interest in electrochemical iron production and hydrogen-based reduction, which aim to eliminate coal from the process entirely. These technologies are promising but not yet mature at scale. They should be developed alongside – not instead of – proven electric arc systems. The near-term future is hybrid: scrap-based production supplemented by low-carbon primary inputs as they become viable.

All of this points to a deeper shift in how we understand industrial resilience. Modern conflict and disruption do not reward large, centralised industrial assets. They reward flexibility, distribution, and rapid adaptation. Steel remains essential – but as an input into advanced systems, not as a standalone pillar.

manufacturing must be treated as global, not narrowly national

The final piece of the puzzle is perhaps the most important. Heavy industry did not simply “disappear” from the UK because demand vanished. It relocated because the conditions for reinvestment became more attractive elsewhere. Energy costs, taxation, regulatory structure, and global supply chains all shaped those decisions.

But this does not mean it can simply be brought back by reversing a single policy lever. Industrial ecosystems are path-dependent. Once supply chains, skills, and capital relocate, they are difficult to reconstruct.

And this leads to a harder, more strategic conclusion: in a world defined by multiple free trade agreements, manufacturing must be treated as global, not narrowly national. The UK cannot behave as if it can wall off its industrial base from global competition – it cannot. The price war in bulk manufacturing was lost decades ago.

That does not mean abandoning industry. It means recognising that you cannot tax manufacturing that has already left – and you should not tax the manufacturing you are trying to attract before it arrives.

This is the real policy failure. The UK has often treated heavy industry as a revenue source rather than a strategic asset. Having spent decades taxing smoking and cheering the success of lower smoking rates – and while the reasons for quitting are complex – will we now repeat the same logic with manufacturing? High energy costs, business rates, and layered taxation have made marginal investment decisions tilt elsewhere. The result is not collapse in a single moment, but a steady absence of reinvestment.

So the policy shift must be explicit: do not tax manufacturing per se. Tax outcomes, tax profits, tax land if necessary – but do not structurally penalise production itself. In a globally mobile industrial system, production goes where it is easiest to sustain. Britain will have industry when global industry locates here.

Which brings us to the central conclusion: a steel industry cannot be rebuilt in isolation. If the UK wants a strong steel sector, it must first rebuild a competitive manufacturing economy that creates sustained demand for steel. Without that, steel policy becomes an exercise in maintaining capacity without purpose.

The choice is not between having steel and not having steel. It is between two different models. One attempts to preserve large, inflexible, legacy systems in the hope that demand will return. The other builds a smaller, smarter, and more adaptable steel sector aligned with the actual structure of the modern economy.

Scotland, with its energy resources and industrial base, is uniquely positioned to anchor that future. Not as a relic of past industrial scale, but as the foundation of a new, integrated system linking energy, materials, and advanced manufacturing.

The question is no longer “how do we save steel?” It is “what kind of economy would actually need it?” Only one answer to that question leads anywhere forward.

This is a sharp correction to many years of thinking across the Right. National pride is one thing; being honest about the nation as it is, is another. For decades, the right has waxed lyrical about nostalgic forms of heavy industry while much of the world has talked less, taxed less, and simply got on with it. Talk has been cheap; tax has been expensive for what remains of Britain’s industrial base.

Consider the comparison. Slovakia did not exist in 1993. With a population similar to Scotland, it now manufactures more cars than the UK as a whole. That wasn’t talked into existence; it was built on a clear strategy aligned to its advantages – and in a landlocked country at that. Portugal, operating within the same Single Market, has not achieved the same outcome. Japan, thousands of miles away, is present on every forecourt.

For those who say Britain is broken, let us ask a question. How is it fixable? That should be food for thought for those rolling up their sleeves to pop the next steel rivet.
