How to read your Margin Diagnostic results

The Margin Diagnostic asks 20 questions across five pillars of margin: commercial and pricing; cost-to-serve and footprint; operations and productivity; procurement and supply base; and data, systems and accountability. You choose an answer from level 1 to level 5 for each question, and the tool turns those answers into a score for each pillar, a comparison with your sector, and an indicative value for each gap.

This guide walks through the results in the order you'll see them.

The pillar scores

Each pillar gets a score between 0 and 4. Next to it you'll see two reference points. One is the sector median, which is roughly where a typical business in your sector sits. The other is the best-in-class mark of 3.6, which is the same for every pillar.

Read the scores in this order:

1. Look for the pillar furthest below the sector median. That is where you are weaker than your peers, and usually where the easiest gains are.
2. Then look at the gap to 3.6. A pillar can sit at the median and still be a long way from best in class. That gap is a longer-term opportunity rather than a quick fix.
3. Ignore small differences. A score of 2.1 against a median of 2.3 is within the margin of an honest self-assessment. A gap of a full point is worth acting on.

The headline score comes with a maturity label that puts the number into words. It is based on the average of your five pillar scores: below 1.0 is Reactive, 1.0 to 1.8 is Emerging, 1.8 to 2.6 is Structured, 2.6 to 3.4 is Managed, and 3.4 or above is Optimised. Reactive and Emerging mean the business is relying on individual effort and memory. Structured means defined processes exist but are applied unevenly. Managed and Optimised mean performance is measured, owned and improved as a matter of routine. Inside each pillar, look at the individual answers too: anything at level 1 or 2 of 5 is usually where the practical fix is.

The value estimates, and why they are indicative

For each pillar, the tool estimates an indicative annual value of closing the gap. It does this using your turnover band and typical value pools for your sector, then shows a range of plus or minus a quarter around the central figure.

Please treat these figures as a guide to where to look, not a forecast. The tool doesn't see your accounts, your customer mix or your contracts. It uses your turnover band rather than your exact turnover. And the sector pools are averages: a business that has already fixed its pricing will have less to gain there than the number suggests, and a business with an unusual cost structure may have more. The plus or minus 25% range is there to remind you of that.

What the estimates are good for is ranking. If one pillar shows three times the value of another, that difference is meaningful even if the absolute numbers are rough.

A worked example

The figures below are illustrative only. They describe an imaginary distributor, not a real business or a real report.

Imagine a building products distributor in the £20m to £30m turnover band. Its results might look like this:

Three things stand out. Commercial and pricing is furthest below the median and carries the largest value, so that is the first place to look. Operations is above the median; the warehouse is probably run reasonably well, and spending management time there first would be a mistake. And data, systems and accountability scores lowest of all but carries a modest value. Weak data rarely costs money directly, but it makes every other improvement harder to prove and harder to keep.

Why would pricing matter so much? McKinsey's long-standing analysis of an average large-company income statement found that a 1% price rise, with volumes held, lifted operating profit by about 8%. Your multiplier will differ, but in a business with thin net margins small price leaks have a big effect on profit.

Turning results into actions

Pick one or two pillars, not five. For each, go back to the individual questions where you answered level 1 or 2. Those answers usually point straight at the practical fix. For example, if a low answer reflects discounts being agreed by individual salespeople with no approval limits, the action is to set limits and review the biggest discounts monthly.

Give each action one owner and a date. Then decide how you'll know it has worked. For pricing, that might be average discount by customer group. For procurement, spend under contract with your top suppliers.

Timing matters too. The Bank of England's Decision Maker Panel for September 2026 found firms expecting to raise their own prices by 3.7% over the next year, with wage growth of 4.0% over the past year. With the National Living Wage at £12.71 since April 2026 and employer National Insurance at 15% since April 2025, labour costs have risen sharply for many businesses. If your commercial pillar is weak, cost increases are probably reaching your margin before they reach your prices.

Finally, repeat the diagnostic in six to twelve months. Answer honestly both times. The movement in your scores is more useful than any single result.

Many organisations almost always underestimate cost-to-serve. They believe their margin problem is pricing, until we show that small orders and special deliveries are eating the margin on their best customers. Seeing one customer's true profit on a single page is usually what changes their mind.
