Why the Best Suppliers Are the Easiest to Lose

Before any organisation retenders a facilities management contract, it should ask the question procurement rarely asks: what exactly are we about to give up?

Every mature facilities management contract reaches the same crossroads. It rarely arrives as crisis; there’s no compliance breach, no visible failure, no single moment forcing a decision. It starts quietly, in a planning meeting, with one question: our contract is due to expire, should we go back to market?

On the face of it, that’s entirely reasonable. Competition drives value, and organisations have a duty to show that money is well spent. In many cases, testing the market is exactly the right call.

The problem isn’t the decision to retender. It’s that most organisations start by asking whether the service could be bought more cheaply, before they’ve properly worked out what they’re already getting for the price.

The bias procurement doesn’t talk about

Procurement teams are trained to work from evidence: prices, staffing ratios, SLAs, KPIs. That discipline is one of the profession’s genuine strengths, and quietly one of its blind spots too.

Not everything of value shows up in a tender matrix. Facilities management runs on relationships, site knowledge and operational judgment built up over years, none of which fits neatly into a pricing schedule. Organisations end up weighting the evidence they can see far more heavily than the value they can’t easily measure. That isn’t a conscious choice so much as a structural one.

When good suppliers become invisible

There’s a genuine irony in long-term outsourcing: the better a supplier performs, the less visible their contribution becomes.

Compliance turns routine. Assets keep running. Problems get solved before anyone upstairs hears about them. Stakeholders stop noticing good service because they’ve never experienced the alternative, and a contract that’s simply working starts to look like a contract that isn’t earning its keep.

This pattern is common enough that experienced FM consultants see it repeatedly across sectors: a well-run contract questioned not because performance has slipped but because it has become familiar. Familiarity, more than underperformance, is usually what triggers the retender conversation.

The asset that never makes the business case

Every well-run FM contract builds up an asset that almost never appears in a procurement report: organisational knowledge.

That’s not just knowing where the plant rooms are. It’s knowing which buildings can’t tolerate a shutdown during exam season, which stakeholder wants speed over process, how security, catering and engineering actually coordinate during a live incident without anyone opening a manual. None of it is written into the specification. It exists because people have solved problems together, repeatedly, over years, and it has real commercial value that is almost never priced. It’s also easy to lose without ever noticing it’s gone.

A large North West university ran into this directly when reviewing its catering service. Rather than relying on benchmark comparisons alone, the review dug into trading activity, cost structures and stakeholder input to test long-held assumptions rather than accept them, separating what people believed about the service from what was actually true, so the eventual decision rested on evidence rather than institutional folklore.

The distinction is worth holding onto. Benchmarking tells you where you stand. Organisational knowledge tells you why you’re standing there. A review that only does the first is working with half the picture.

The economics that don’t show up in the tender

Changing supplier gets framed as a comparison of two prices, but it’s really a comparison of two operating models, and every switch carries transition costs, some visible and most not.

The visible ones are familiar: mobilisation, technology integration, legal and procurement time, retraining, new governance. The costly ones rarely make it into a business case at all: management distraction during transition, a temporary dip in service consistency, the months it takes a new relationship to mature to where the old one already was.

Economists call these transaction costs, the resources burned simply in moving from one commercial arrangement to another. In complex estates, whether a hospital, a multi-site logistics operation or a university, where operational continuity is non-negotiable, these costs can be substantial.

One national corporate organisation felt this directly when mobilising a new catering contract across multiple sites. The opportunity to improve service was real, but so was the strain. The same stakeholders responsible for running the business day to day were also expected to oversee mobilisation, review supplier submissions, monitor implementation and hold the line on continuity, all on top of their existing workload.

What changed the outcome wasn’t the mobilisation plan itself but who was watching it. Independent oversight tracked progress against the plan, pressure-tested assumptions as they surfaced, and flagged risk early enough to act on it, freeing senior managers to keep running the business rather than splitting their attention across two jobs.

The contract went live with clear governance and measurably less disruption than an unmanaged transition would have produced. A mobilisation isn’t just a milestone to hit. It’s a period where organisational knowledge, management bandwidth and business continuity are all simultaneously at risk, and treating it as a pure implementation task rather than something requiring its own scrutiny is exactly how transition costs go unpriced until they’ve already been paid.

Across more than £150m of FM tendering we’ve overseen, spanning healthcare, logistics, retail and education, we’ve seen the same pattern hold. Contracts rarely fail overnight. They drift. The same is true in reverse: the value of stability rarely announces itself either.

Treating transition cost as an implementation footnote rather than a strategic input is where the analysis usually breaks down.

Why benchmarking isn’t the answer, only a starting point

Benchmarking is a sensible instinct, and increasingly a contractual one. Many long-term FM and PFI contracts now build in benchmarking clauses that activate automatically as the contract matures. It tells you how your costs compare with the wider market. It cannot tell you why.

The estate might be more complex. Compliance requirements might be higher. Staffing models might differ. Or the incumbent might simply have built operational practices over years that reduce disruption in ways no financial model captures.

Used well, benchmarking is one input into a decision. Used badly, it becomes the decision, quietly pushing organisations toward optimising cost while losing track of value.

One recent review illustrates the point. On the surface, there was nothing to flag: the supplier was performing well, the client had no complaints, and the invoices matched the contract line for line. A standard market-average benchmark would likely have confirmed the price was reasonable and moved on.

The reviewers asked a different question, not how much was being paid but why. That shift uncovered a set of assumptions nobody had revisited in years: labour models that predated changes in how the buildings were actually used, management costs that had simply become accepted as normal, specifications that no longer matched current operations.

None of it showed up as a red flag against a market average, because a market average only tests the price, not the logic behind it. Once those assumptions were challenged individually, the review identified over £250,000 in savings without changing supplier or cutting the service the client actually needed.

The lesson isn’t that benchmarking is worthless. It’s that benchmarking doesn’t save money on its own; challenging the assumptions underneath the numbers does. Benchmarking simply supplies the evidence to make that challenge with confidence.

The better question, asked earlier

Here’s the principle that should reshape how these reviews get run: the decision to retain an incumbent should require exactly the same rigour as the decision to replace one, not because incumbents deserve the benefit of the doubt, but because both routes carry commercial risk and only one of them is currently being scrutinised properly.

Before any tender is issued, procurement should be able to answer:

• Why does our current contract cost what it does, and how much of that is genuine operational need versus habit?
• Are we benchmarking the price, or challenging the assumptions behind it? When was the last time someone asked why, rather than simply accepting what?
• How much organisational knowledge has this contract built, and what would it cost to rebuild it from zero?
• What would we actually be exposed to during transition, in a bad-case scenario, not just the average one?
• Could the outcomes we’re chasing be delivered through renegotiation rather than replacement?

None of this weakens procurement. It’s what makes a retender decision, or a retention decision, defensible when someone asks why six months later.

The real cost at stake

Facilities management now runs on richer data and better benchmarking than at any point in its history, and under the UK’s Procurement Act 2023, which came into force in February 2025, public sector buyers face the most significant overhaul of procurement rules in decades. Better information and better process both help.

Neither one, on its own, produces a better decision.

The organisations that get this right aren’t the ones that retender most often, or the ones that never do. They’re the ones that can explain, in plain terms, exactly why they chose one path over the other, and have priced the full cost of that choice before signing anything.

The real risk was never the cost of changing suppliers. It’s the cost of a decision made without knowing what was actually on the table.
