The past five years have tested UK manufacturing supply chains in ways that no continuity plan fully anticipated. Pandemic shutdowns, energy price shocks, port congestion and geopolitical friction have each, in turn, exposed the same underlying weakness: most manufacturers know their Tier 1 suppliers reasonably well, but beyond that, visibility drops off sharply. When a disruption hits three or four layers back, the first sign is often a customer asking why their order is late.
At Kingfisher Building Products, we manufacture specialist construction protection systems: waterproofing compounds, damp proofing treatments, sealants and protective coatings for infrastructure, housing and industrial projects. Our products depend on a specific set of chemical raw materials including polymer resins, pigment dispersions, biocide actives and cementitious binders, sourced from a relatively small number of global suppliers. When those networks buckled between 2020 and 2023, we felt it directly on the production floor.
Here’s what those disruptions taught us, and what we believe mid-sized manufacturers can do to build genuine resilience.
Acknowledge where your visibility actually ends
The first step is admitting how little most manufacturers know about their own supply chains below Tier 1. You can probably name your key direct suppliers and have a reasonable sense of their financial stability and lead times. Ask about their suppliers, and the picture gets murkier. Ask about those suppliers’ suppliers, and you are largely guessing.
During the 2021 raw material crunch, we discovered that two of our apparently independent chemical suppliers were drawing from the same single-source intermediary in continental Europe. When that intermediary reduced output, both suppliers were constrained simultaneously. We hadn’t structured our sourcing to protect against this because we didn’t know the dependency existed in the first place.
Mapping your supply chain beyond Tier 1 isn’t a quick exercise, but it doesn’t need to be exhaustive to be useful. Start with your highest-volume inputs and your most business-critical materials. Ask your Tier 1 suppliers directly where their key inputs originate, and document it. That exercise alone will surface dependencies you would rather find in a planning meeting than during a production stoppage.
Audit single-source dependencies, then act on what you find
Single-source relationships aren’t inherently a problem. Sometimes a supplier offers a product, formulation or specification that can’t be replicated elsewhere, and consolidating volume can deliver better pricing and service. The issue arises when single-source positions exist by default rather than by design: when no one has ever evaluated alternatives, or when switching costs have quietly accumulated until switching feels impossible.
After mapping our critical raw material flows, we identified several inputs where we had drifted into single-source positions without a deliberate decision ever having been made. For some, we ran parallel qualification programmes with alternative suppliers. For others, we negotiated extended lead times and consignment stock arrangements that protected our production schedule during periods of supply pressure.
The goal isn’t to have two of everything. It is to have a clear, documented view of where you’re exposed and a proportionate response to each risk. That proportionality matters: not every single-source dependency warrants the same level of contingency planning, and spreading resource thinly across every potential risk is as counterproductive as ignoring risk altogether.
Build supplier communication into the operating rhythm
During peak disruption periods, the manufacturers who managed best were not always those with the deepest pockets or the most sophisticated procurement systems. They were often those with the strongest supplier relationships: the ones whose calls got answered first, who received early warning of allocation constraints, and who were offered first option on available stock.
Most companies treat supplier communication as reactive rather than routine. Orders go in, invoices come back, and meaningful conversation happens only when something goes wrong. That model leaves you entirely dependent on suppliers choosing to share information proactively, which they aren’t always motivated to do.
We moved to a more structured cadence: quarterly reviews with our key chemical and packaging suppliers that go beyond price and lead time to cover their capacity outlook, input availability, and any regulatory or raw material changes on their horizon. The output is rarely dramatic, but the early signals it produces have, on more than one occasion, allowed us to pull forward orders or adjust formulations before a problem became a crisis.
One example: a supplier conversation flagged an upcoming regulatory change affecting the biocide active used in our anti-mould paint range. Having that information six months ahead of the change, rather than discovering it on an order rejection, gave us time to requalify an alternative active and update our product documentation without any interruption to supply. That kind of lead time only comes when communication is routine, not transactional.
Focus on responsiveness, not just buffer stock
The instinctive response to supply chain disruption is to hold more inventory. Increasing buffer stock does reduce short-term exposure, but it also ties up working capital, introduces warehousing costs and creates obsolescence risk. For chemical manufacturers with shelf-life constraints, that last point is a significant operational consideration.
Responsiveness is the more useful frame. Rather than asking how much stock you need to ride out a disruption, ask how quickly you could adapt your production schedule, reformulate a product, or switch to an alternative input if your primary supply were interrupted. The answers will shape a different set of investments: in production flexibility, in supplier qualification breadth, and in the depth of technical knowledge your team holds about your own formulations.
For UK manufacturers, post-Brexit trade flows have also made supply chain geography a more active consideration, with shorter, more predictable routes to key inputs reducing exposure when systemic shocks hit.
Start with the decisions already in front of you
Supply chain resilience can feel like an enormous undertaking. In practice, the most effective improvements tend to come from a series of modest decisions made consistently over time: mapping one more tier of the supplier network, qualifying one alternative source, establishing one more regular supplier review.
The manufacturers who came through recent disruptions with the most confidence were those who had already begun that work before disruption arrived. Those who struggled assumed stability would continue and had no contingency to activate when it did not.
No supply chain can be made disruption-proof. But one that is well-managed can absorb disruption, adapt quickly and keep production running. Building that capability is achievable for mid-sized UK manufacturers without the resources of a global corporation. It starts with a clear view of where you are exposed and a consistent commitment to closing those gaps, one decision at a time.
