Reshoring has become one of those words that means whatever the speaker needs it to mean. To politicians it promises the return of industrial employment. To procurement directors it means something narrower and more practical: moving a specific component closer to the assembly line because the risk of not having it has become intolerable.
Both descriptions can be true simultaneously, which is why the debate is so confused. Supply chains genuinely are shortening. Manufacturing employment is not returning in proportion, because the processes coming back are the ones that can be automated.
What is actually moving
The clearest movement is in components where the cost of failure dwarfs the cost of production: aerospace fasteners, medical devices, defence electronics, pharmaceutical intermediates and specialist castings. In each case a shipping delay or a quality escape can halt a production line worth millions a day, and that asymmetry justifies paying more for proximity.
Surveys by Make UK have tracked a steady rise in firms reporting they have moved some sourcing back to Britain or nearer Europe. The same surveys find the primary motivation is resilience rather than cost, which is an important distinction: resilience-driven reshoring survives a return to cheap freight, cost-driven reshoring does not.
Why employment does not follow
A modern reshored plant is a building with a small number of highly skilled people and a great deal of capital equipment. The economics of bringing production home depend on automation, because British labour costs cannot compete on volume assembly. That means output can rise substantially while headcount barely moves.
Productivity statistics from the Office for National Statistics capture this poorly at sector level, because the firms doing it are small in number and large in capital intensity. The result is a genuine industrial shift that is almost invisible in the headline employment data politicians quote.
The energy cost obstacle
The single largest constraint on British manufacturing competitiveness is industrial electricity pricing, which has run persistently above the levels paid by competitors in France, Germany and the United States. For an energy-intensive process such as glass, ceramics, chemicals or metals, that difference can exceed the entire labour cost advantage of automation.
Comparative figures published by the International Energy Agency illustrate how much of the gap comes from policy costs layered onto industrial tariffs rather than from wholesale prices. That makes it a fixable problem in principle and a politically awkward one in practice, because the levies fund decarbonisation commitments.
Skills, again
Every reshoring conversation eventually arrives at the same place: the availability of maintenance engineers, controls specialists, machinists and technicians who can keep automated lines running. These are the roles that gate expansion, and they take years to train. A firm can install a robot cell in three months and wait two years for the people who can fix it.
This is why industrial policy and skills policy cannot be separated. Capital allowances accelerate investment decisions. They do not produce technicians, and a factory that cannot be maintained is worse than no factory at all.
What a serious strategy would prioritise
Sequence matters more than scale. Fix industrial energy costs first, because they determine whether the investment case closes at all. Fund technical training with employers rather than around them. Use public procurement, particularly in defence and health, as a demand signal that justifies private capital expenditure. And treat planning consent for industrial sites with the same urgency now reserved for housing.
Done in that order, reshoring becomes an industrial strategy. Done in reverse, it becomes a press release attached to a factory that was going to be built anyway.
What reshoring requires that Britain does not yet have
Reshoring conversations tend to founder on the assumption that the decision is primarily about labour cost. For most of the manufacturing that Britain could plausibly attract back, labour is no longer the binding constraint — automation has compressed the wage share of unit cost to the point where a modern line in Sheffield is competitive with one in Guangdong. The binding constraints are industrial electricity prices, grid connection timescales, planning consent, and the depth of the local supplier base.
Industrial electricity is the most quantifiable problem. British manufacturers pay materially more per unit than competitors in France, the United States or much of Asia, and for energy-intensive processes that differential alone can decide a site selection. Grid connection is the most frustrating, because the delay is measured in years rather than months and cannot be solved by the investor at any price. Together they mean that a firm weighing a new UK line is often choosing between a competitive operating cost it cannot access and a slower timetable it cannot control.
The supplier-base problem is subtler and more damaging in the long run. Manufacturing clusters work because a firm can source a specialist casting, a heat treatment, or a precision grind within a short drive. Britain lost much of that intermediate layer between 1980 and 2010, and it does not regenerate in response to a single anchor investment. It requires sustained demand visibility of the sort that long procurement pipelines in defence, rail and energy can provide, if government is willing to commit to timetables it will actually keep.
Where those conditions exist — aerospace around Bristol, automotive around the Midlands, life sciences along the Oxford and Cambridge corridors — Britain remains genuinely competitive. The policy task is less about persuasion than about removing the specific frictions that make otherwise sound investment cases fail on timing.
