Most cleaning business operators have never calculated Revenue Per Head (RPH). It takes two numbers and thirty seconds. RPH tells you more about your business’s health than your last management accounts.
The Growth Lab Profitability Index analysed 20 verified UK cleaning and FM businesses, cross-referenced against Plimsoll’s dataset of 1,871 UK FM firms. Only 82 of those companies achieved four consecutive years of profit growth.
4%
The other 96% aren’t failing because of poor operations or not winning work.
They’re growing revenue while RPH stays flat. That’s not growth. That’s dilution.
The Number You’re Not Calculating
Two numbers. Both available today. No accountant required.
RPH is the most predictive metric in a direct-employment Soft FM business. It tells you more about your commercial health than gross margin, turnover, or growth rate.
Why?
Because RPH captures the relationship between revenue generated and baseline employment cost.
The current baseline is £31,000 per operative per year. That’s the minimum all-in cost of one employed cleaner:
National Living Wage at 37.5 hours per week
Employer National Insurance
Pension, uniform, vetting, training, and travel.
Every component is a fixed or statutory cost — none of it is discretionary. Due to NLW, this number has risen 22% since April 2023. It’s due to rise again next month (April 2026) when NLW increases to £12.71/hour.
Every £1 of RPH above £31,000 is your gross profit per head. The gap between RPH and that floor is the only number that matters.

The Four Zones
The GLPI identifies four RPH zones for direct-employment cleaning businesses. Every operator sits in one of them. Most don’t know which.
The Profit Gap - What £30K Difference Actually Costs
The delta between Survival and Health is approximately £30,000 in RPH. That gap results in a 33% difference in margin outcomes — verified across the GLPI dataset.
The full GLPI Baseline Report provides more detail.
If these numbers raise questions about your own business, the GLPI Baseline Report gives you the complete picture. RPH benchmarks by operator size. Margin profiles by zone. The commercial decisions that separate the 4% from the 96%.

Your Next Move
RPH doesn’t improve through operations. You cannot supervise your way from £38,000 to £68,000. You cannot hire your way there. Technology won’t get you there at SME scale either.
RPH is the output of three commercial decisions:
Who you sell to - ICP clarity determines which contracts you win and at what rate
What you charge - your pricing model determines your billing rate per operative hour
What you accept - portfolio discipline determines whether strong-RPH contracts get diluted by weak ones
If you’re in the Danger or Survival Zone, the pattern is almost always the same. You priced on cost-plus. You bid market rate, not value rate. You accepted volume without pricing discipline. And while NLW has increased by 22% since 2023, your contract prices haven’t kept pace.
The billing rate is a commercial decision. The employment cost floor is not.
THE CALCULATION — DO THIS NOW
Take your last 12 months of revenue. Divide it by the total number of people currently on your payroll. Include everyone: operatives, supervisors, coordinators, managers, admin, and yourself.
That number is your RPH. Compare to the zone table above.
The Bottom Line
The 4% who grow profitably don’t get there by working harder. They get there by knowing their ICP, pricing at value, and refusing work that drags the number down.
That clarity starts with knowing your RPH zone — and understanding which of the three commercial decisions is holding you there.
Know your zone. Understand why you’re in it.
The GLPI Baseline Report is the only benchmark built for direct-employment UK Soft FM operators. 20 verified businesses. Real margin data. The four RPH zones mapped against actual commercial decisions.
If your number sits in Survival or Danger, this report tells you exactly what the Health Zone businesses are doing differently — and which of the three commercial decisions to fix first.
