50 Deals and Counting: Why FM Consolidation Is the Biggest Risk Hiding in Your Contract

By Ernie Melling, IFMA Consultants Council

The proposed acquisition of OCS by Mitie has dominated discussion across the FM sector in recent weeks.

Much of the commentary has focused on market share, strategic fit and what the deal means for the organisations involved.

I think there’s another question that deserves just as much attention.

What does another major acquisition mean for organisations buying FM services?

Because this isn’t an isolated transaction. It’s part of a much bigger pattern that has been reshaping the UK FM market for several years. From where I sit, the implications for buyers are far more significant than many organisations realise.

I had a conversation recently with an estates director that perfectly illustrated the point.

“We ran a tender three years ago and had six strong bidders. We’re preparing to retender now, and two of them have been acquired, one has merged, and another has pulled out of our sector entirely. We’ve gone from six to three. And one of those three is the incumbent.”

That’s not a procurement problem. That’s a market structure problem.

It’s happening across the UK FM sector at a pace I haven’t seen in over 15 years of managing tenders and contracts.

The numbers tell the story

Q2 2026 saw 50 FM transactions across the UK and Ireland, 31% above the long-term quarterly average. Building maintenance and M&E deals were up 24% year-on-year (BDO). Soft FM consolidation is accelerating across cleaning, security and landscaping as businesses expand to offer integrated FM solutions. In 2024, the sector recorded 181 mergers and acquisitions, a 34% rise from 2021.

Read most M&A reports and the tone is understandably positive. Consolidation is presented as greater scale, increased investment and enhanced technical capability.

From the supplier perspective, much of that is true.

Larger organisations can invest more heavily in technology, compliance, specialist expertise and national coverage than many smaller providers ever could.

But I spend my time on the client side of the table.

From there, consolidation is quietly changing the commercial risk profile of almost every FM contract.

What the efficiency narrative misses

When a supplier is acquired, the press release talks about investment, capability and enhanced service delivery.

What it rarely discusses is what happens to the client contract during the transition.

I’ve seen it happen too many times.

The account manager who knew your estate inside out is replaced.

The SLA reporting tailored around your operational priorities becomes absorbed into a standard corporate reporting platform.

The pricing model negotiated around your specific risk profile is gradually harmonised with the acquiring company’s commercial framework.

None of this is malicious.

It’s simply what happens when your contract becomes one of hundreds within a much larger organisation.

Your carefully negotiated arrangements can quickly become a very small part of a much bigger business.

The buyer rarely sees it coming.

The first sign is often a dip in service performance explained away as “transition issues.”

The second is a pricing review that wasn’t anticipated.

The third is realising that several of the suppliers you shortlisted only a few years ago no longer exist as independent competitors.

What consolidation actually costs the buyer

The cost isn’t immediately visible on an invoice.

It’s structural.

And over time, it compounds.

Loss of competitive tension

This is perhaps the most significant consequence.

Competition isn’t simply about how many suppliers submit bids.

It’s about how many genuinely independent commercial strategies are competing for your business.

Six logos on a tender list may now represent only three ownership groups.

When your market shrinks from six viable suppliers to three, your leverage changes.

Pricing may remain competitive initially, but over time the balance of power shifts.

Innovation slows.

Negotiations become harder.

Contract renewal begins to replace genuine competition.

SLA drift through transition

Acquisitions inevitably create operational change.

Key personnel move on.

Knowledge transfer is rarely perfect.

The service standards originally agreed can gradually be interpreted differently by new operational teams who were never involved in writing the contract.

Performance slips, but often so gradually that it becomes accepted as normal.

Erosion of negotiated terms

Many organisations assume the contract they negotiated will continue to operate exactly as intended.

In reality, ownership changes often introduce new governance models, commercial processes and contractual interpretations.

I’ve seen change-of-control clauses that looked robust on paper prove difficult to enforce because ownership structures evolved in ways the contract never anticipated.

Shrinking strategic options

Every FM contract should be written with a credible exit strategy.

Consolidation quietly narrows those options.

If several realistic alternatives have been absorbed into larger groups, transitioning supplier becomes more complex, more expensive and potentially more disruptive.

That changes the commercial dynamic, whether either party acknowledges it or not.

What I’d be asking right now

Whether you’re a CFO, Estates Director or Procurement Lead, these are the questions I’d be asking.

• Who ultimately owns your FM provider today? Not simply the trading name on the invoice, but the parent organisation behind it. Has ownership changed since contract award?
• Does your contract contain a meaningful change-of-control clause? One that gives more than notification. Can it trigger renegotiation, benchmarking or, where appropriate, termination?
• When did you last benchmark your contract against today’s market rather than the market that existed when the contract was awarded?
• Does your exit strategy still reflect reality? Are your alternative suppliers still independent? Are they still active in your sector?
• Is your contract management evolving as quickly as the market? Governance, benchmarking rights, pricing review mechanisms and performance frameworks should all be reviewed as markets consolidate.

The case for independent oversight

I’m not anti-consolidation.

Some of it is healthy.

Scale can deliver genuine improvements in technology, investment and technical capability.

But larger organisations also create greater distance between the client and the commercial decisions that shape contract delivery.

That makes governance more important, not less.

Whether the proposed Mitie acquisition of OCS proceeds as planned or not, it highlights a wider trend that has been building for several years.

Buyers should resist viewing this simply as another corporate transaction.

It is another reminder that the structure of the FM market is changing, and procurement and contract management need to evolve with it.

Most FM contracts were written for a market that no longer exists.

The pricing assumptions, governance arrangements and competitive landscape they were designed around have fundamentally changed.

I’ve spent more than 15 years managing FM tenders and contracts, covering more than 200 procurement exercises.

The pattern I see today feels different.

Not because acquisitions are new.

Because of the pace at which buyer choice is narrowing.

The real issue isn’t whether consolidation will continue.

Every indication suggests it will.

The question is whether buyers continue managing FM contracts as though the market still looks the way it did five years ago.

In my view, that’s becoming one of the biggest commercial risks in facilities management.
