Benchmarking vs Forensic Benchmarking in FM

Why the difference is costing organisations millions (and how to fix it)

In facilities management, benchmarking is often treated as a comfort blanket.

A quick comparison.
A neat report.
A reassuring answer.

“You’re in line with the market.”

But here’s the uncomfortable truth:

Most benchmarking exercises don’t actually tell you if you’re overpaying.

They tell you if you look similar to everyone else.

And that’s where the problem starts.

What is Traditional Benchmarking?

At its core, benchmarking compares your costs, services, or performance against a dataset of similar organisations.

Typically, it answers questions like:

• Are my cleaning costs per m² in line with the market?
• Is my security headcount typical for this type of building?
• Do my catering costs sit within industry averages?

On paper, it sounds logical.

But in reality, it’s often built on:

• High-level cost data
• Assumed service scopes
• Generic building classifications
• Incomplete or inconsistent inputs

Which leads to one critical flaw:

It compares numbers… not reality.

The Problem with Traditional Benchmarking

Over the past 25 years, I’ve reviewed countless “benchmark-compliant” contracts that were quietly leaking money.

Not because anyone was doing anything wrong.

But because the benchmark itself was flawed.

Common issues include:

• Apples-to-oranges comparisons (different scopes, same category)
• Hidden service variations (frequencies, standards, inclusions)
• Legacy contract inefficiencies baked into the data
• Over-reliance on £/m² or cost per head metrics

The result?

A false sense of security.

You’re told you’re “market-aligned”…
while carrying 5–15% inefficiency you can’t see.

---

What is Forensic Benchmarking?

Forensic benchmarking takes a completely different approach.

It doesn’t start with the market.

It starts with your contract.

Then it rebuilds the truth from the ground up.

A forensic benchmark examines:

• The actual service scope (not assumed)
• Task frequencies and specifications
• Staffing models and productivity assumptions
• Site-specific variables (layout, utilisation, risk)
• Contractual obligations vs operational reality

Only then does it compare against the market.

And crucially:

It adjusts the market to match your reality, not the other way around.

---

The Key Difference

• Benchmarking asks:
  “Are we similar to others?”
• Forensic benchmarking asks:
  “What should this cost, based on what we actually do?”

That difference is where the value sits.

Real-World Example 1: Cleaning Contract

We reviewed a corporate office portfolio where the client had been told their cleaning costs were “within benchmark.”

At first glance:

• £/m² aligned with industry data
• Headcount looked typical
• No obvious red flags

But the forensic review revealed:

• Over-specified cleaning frequencies in low-use areas
• Inefficient zoning increasing labour hours
• Legacy staffing models unchanged for 10+ years

Outcome:

• 11% cost reduction without reducing service quality
• Improved cleaning coverage in high-traffic areas
• Clear audit trail to support procurement decisions

The original benchmark didn’t pick any of this up.

Because it wasn’t looking for it.

---

Real-World Example 2: Catering Contract

In a multi-site catering review, the client believed their subsidy levels were “normal.”

The benchmark said they were fine.

But forensic analysis uncovered:

• Hidden subsidy embedded in staffing structures
• Menu engineering issues driving waste
• Misaligned trading hours vs demand

By asking better questions and rebuilding the cost model:

• Subsidy reduced by £180k annually
• Service improved due to demand-led adjustments
• Commercial model reset for future tenders

Again, the benchmark didn’t fail.

It just wasn’t designed to see the problem.

---

Real-World Example 3: Security Provision

A large estate was operating with a benchmark-supported security model.

But the forensic review showed:

• Static guarding where technology could replace coverage
• Overlapping shifts creating duplication
• Risk profile changes not reflected in the contract

Outcome:

• 9% cost saving
• Improved risk coverage through smarter deployment
• Stronger alignment between cost and actual security needs

---

Why Forensic Benchmarking is Worth the Investment

At first glance, forensic benchmarking appears more detailed… and therefore more expensive.

But that’s the wrong way to look at it.

Because the real question is:

What is the cost of not doing it properly?

Typical outcomes we see:

• 5–12% cost optimisation across soft services
• Reduced risk of disputes during contract renegotiation
• Stronger position in tender negotiations
• Clear, defensible data for stakeholders and auditors
• Better service alignment with operational needs

In simple terms:

It pays for itself. multiple times over.

---

When Should You Use Forensic Benchmarking?

It becomes critical when:

• You’re within 12–24 months of contract renewal
• You’re preparing for a tender or re-tender
• Costs feel “about right” but lack transparency
• You’ve inherited a legacy contract
• Benchmarking results feel too good (or too vague) to question

If you wait until mobilisation…

It’s already too late.

Frequently Asked Questions (FAQ)

1. Isn’t benchmarking enough for most organisations?

For high-level insights, yes.
But if you’re making procurement or contract decisions worth millions, high-level isn’t enough.

---

2. How long does a forensic benchmarking exercise take?

Typically 4–8 weeks depending on portfolio size, data availability, and service complexity.

---

3. Do I need perfect data to start?

No. In fact, most clients don’t have perfect data.
Part of the forensic process is validating and rebuilding it.

---

4. Will this disrupt my current supplier relationship?

Not if handled correctly.
In many cases, it improves transparency and strengthens collaboration.

---

5. Is forensic benchmarking only about cost reduction?

No.
It’s about value alignment — ensuring you pay the right amount for the right service.

Cost savings are often a by-product.

---

6. Can this support a future tender?

Absolutely.
It creates a clean, evidence-based foundation for scope design, pricing models, and bid evaluation.

Final Thought

Benchmarking tells you where you sit.

Forensic benchmarking tells you where you should be.

And that gap?

That’s where the money is.
