The Shrinking Nearshore Discount: Five Tests for UK Manufacturers Weighing a Move

Nearshoring has become the default answer in British boardrooms whenever supply-chain risk is raised. The pitch is familiar: shorter lead times, a European or Mediterranean time zone, lower labour costs and a reduced exposure to the geopolitical fragility of long-haul routes. Each element contains truth. Taken together, they are frequently presented as a package rather than as a set of claims that need testing.

The difficulty in 2026 is that the arithmetic has moved. Labour costs across Central and Eastern Europe have risen faster than in the UK for several years. Industrial energy prices remain structurally higher than in the United States and parts of Asia. Rules of origin have become an active commercial constraint rather than a compliance footnote. None of this invalidates nearshoring; it simply means the comparison must be built on unit costs and total landed cost rather than on headline wages.

Assumption one: the wage gap will stay wide

The wage gap is real, and it is narrowing. Minimum wage levels in Poland, Czechia and Romania have climbed steadily, and skilled engineering salaries in the main industrial clusters have converged towards Western European levels faster than most five-year plans assumed. What matters commercially is unit labour cost — wages divided by output — and that requires an honest view of productivity, training, absenteeism and staff turnover in the specific plant being considered.

A UK manufacturer of precision components recently found that its Polish alternative carried a 40 per cent labour advantage that narrowed to single digits once tooling transfer, quality engineering, expatriate management and additional inventory were loaded in. The gap did not vanish. It stopped being decisive.

Assumption two: energy will be cheaper

Energy-intensive processes — heat treatment, ceramics, glass, chemicals, large-scale forming — are acutely sensitive to this assumption, and it is the one most often left unexamined. Wholesale and industrial tariffs across the continent vary markedly, and Turkey and North Africa present a different profile again. The relevant comparison is delivered cost per unit of output after efficiency losses, including the capital required to run existing UK equipment on a different supply voltage and tariff structure.

Where energy is a material share of the cost stack, the nearshore case should be built bottom-up from plant-level consumption data. Where it is marginal, the analysis can be lighter. Applying a single European average to every process is how plausible business cases acquire an unfounded precision.

Assumption three: rules of origin are somebody else's problem

This is where nearshoring decisions most often become expensive after the fact. A UK manufacturer that moves assembly to Turkey and ships finished goods into the EU may find that the product no longer meets the applicable origin rule, because the UK–EU agreement rewards bilateral and diagonal cumulation on specific terms, and the UK–Turkey arrangement does not automatically confer the same treatment. Processing that is judged insufficient — a light assembly, a packaging operation, a minor modification — will not shift origin, and the tariff will follow the goods regardless of where the invoice is raised.

The same applies in reverse for UK-bound flows under preferential arrangements with Morocco, Tunisia and Egypt, and to the documentation regime that supports them. Supplier declarations, long-term statements and bill-of-materials lineage need to be designed into the sourcing plan, not retrofitted when HMRC asks a question.

Assumption four: logistics will be reliably faster

Road freight from Poland or Czechia to the Midlands is measured in days rather than weeks, and that is a genuine advantage for responsiveness and working capital. It is not, however, an advantage that survives a driver shortage, a channel crossing disruption, a port congestion event or a new border formality without cost.

Two developments deserve particular attention in 2026. The EU's carbon border adjustment mechanism is now in its definitive phase for covered goods, which affects manufacturers importing iron, steel, aluminium, cement, fertiliser, hydrogen and electricity into the EU, and adds a reporting and cost layer to the routing decision. Alongside it, the EU's import control systems and deforestation rules continue to expand the documentary burden on goods crossing into the single market. Nearshoring reduces distance; it does not reduce paperwork.

Assumption five: the supplier base will scale with you

A nearshore site is only as good as its second and third tier. UK manufacturers frequently discover that the tier-one partner is excellent and the tier-two network behind it is thin, poorly capitalised or dependent on imported inputs from the very regions the move was designed to avoid. Tooling capability, metrology, materials availability and engineering depth vary enormously between clusters 200 kilometres apart, let alone between countries.

Resilience also has a human dimension. A single site with one shift pattern and one qualified maintenance team is not a diversified supply chain; it is a relocation of the original single point of failure.

A framework for comparing domestic, nearshore and offshore

Rather than debating locations in the abstract, score each candidate against weighted criteria:

• Total landed cost per unit, including duty, freight, energy, inventory and quality cost.
• Cash-to-cash cycle and the working capital tied up in transit and buffer stock.
• Time to mobilise, including tooling transfer, qualification and customer approval.
• Skills depth and the availability of a second-tier supplier network.
• Compliance burden, covering origin, product regulation, carbon reporting and customs documentation.
• Currency exposure and the sensitivity of the case to a 15 per cent movement in sterling.
• Resilience under a defined stress test, such as a three-week disruption on the primary route.
• Exit cost, including redundancy, lease liabilities and unrecoverable tooling investment.

The discipline lies in holding the weights constant across options and revisiting them when the board's priorities change. A cost-led strategy and a resilience-led strategy will produce different winners from the same data.

What a defensible decision looks like

Firms that get this right rarely move everything at once. They pilot a single product family, dual-source through the transition, and write contractual exit provisions before signing a lease. They test the case against adverse scenarios rather than only against the base case. And they treat the nearshore option as one candidate among three rather than as a settled conclusion looking for supporting evidence.

Nearshoring remains a credible answer to genuine supply-chain risk. What it is not is a shortcut. For UK manufacturers in 2026, the value lies in the rigour of the comparison rather than in the geography itself.
