HookThames Water — a balance sheet you can smell
When Thames Water was privatised in 1989 it was handed to shareholders virtually debt-free. By 2024–25 the UK's biggest water company was carrying borrowings of roughly £19bn, with gearing around 80% of its regulatory capital value — far above the 55–60% its regulator assumes a prudent water company would run. Much of the transformation happened under Macquarie's ownership (2006–2017), when dividends totalling roughly £2.7bn flowed out while debt piled up. When interest rates rose after 2021, the interest bill swallowed the cash the business needed for pipes and sewage works, and by 2023 the company's survival was a running national story.
Nothing in that paragraph requires inside information. All of it was sitting in Thames Water's published accounts for years — for anyone who knew where to look. That is what B3.5 trains: reading a statement of comprehensive income and a statement of financial position, distilling them into two ratios (ROCE for how hard the capital works, gearing for how the business is financed), and then reading the workforce numbers — productivity, turnover, absence — that the financial statements silently depend on. Competitiveness is measurable, and the measurements were public all along.
ModelThe two statements — what each one actually shows
The statement of comprehensive income is a film of the year's trading: revenue at the top, then cost of sales taken off to give gross profit, then operating expenses off to give operating profit, then interest and tax to reach the profit for the year. It answers ‘did this business trade well?’. The statement of financial position (balance sheet) is a photograph taken on one day: non-current and current assets on one side; current liabilities, non-current liabilities and shareholders' equity on the other. It answers ‘what does this business own, owe, and how is it funded?’.
Different stakeholders read them with different fears. Shareholders look at profit and dividends; lenders look at debt levels and what security exists; suppliers check liquidity before extending credit; employees and unions read profitability ahead of pay claims; managers mine both for decisions. And the statements have honest limitations worth two evaluation marks anywhere: they are historical (last year, not next), they can be window-dressed (timing sales and payments around the year-end), and the things that most drive future competitiveness — brand, culture, talent — appear almost nowhere in them.
ModelROCE — the interest rate a business earns on itself
Return on capital employed = operating profit ÷ capital employed × 100, where capital employed = non-current liabilities + total equity — all the long-term money in the business, whoever provided it. ROCE is the profitability ratio because it answers the investor's real question: what rate of return does this firm generate on the capital tied up in it?
A ROCE figure means little naked. Judge it three ways: against the firm's own history (rising or falling?), against rivals in the same industry (capital-heavy industries run structurally lower ROCE than software), and — the sharpest test — against the cost of borrowing. If ROCE sits below the interest rate on the firm's debt, the business destroys value with every pound it borrows. Improving ROCE has only two levers, and naming them shows an examiner real understanding: raise operating profit without new capital (prices up, costs down), or shrink the capital employed while holding profit (sell underused assets, run leaner stock).
A regional brewer reports operating profit of £50m on capital employed of £400m (total equity £250m plus non-current liabilities £150m). ROCE = 50 ÷ 400 × 100 = 12.5%. Context makes the number speak: with bank borrowing costing around 6%, every borrowed pound earns roughly twice its cost — healthy. If next year profit falls to £30m on the same capital, ROCE = 7.5%, and the gap over borrowing costs has nearly closed. Same brewery, same assets — but the second version has almost no room for error.
ModelGearing — who really owns the business
Gearing = non-current liabilities ÷ capital employed × 100. It measures what proportion of the firm's long-term funding is debt rather than owners' money. Above roughly 50% a firm is conventionally called highly geared; below 25%, low geared. Neither is automatically ‘bad’ — that is the point examiners most want you to grasp. Debt is cheaper than equity (interest is tax-deductible and lenders accept lower returns than shareholders demand), so gearing up can supercharge returns to owners when ROCE exceeds the interest rate.
The danger is that interest is a CONTRACT and dividends are a choice. A struggling firm can cancel its dividend; it cannot cancel its interest. High gearing therefore magnifies both directions: fatter shareholder returns in good years, existential risk when profits fall or rates rise. That is the Thames Water story in one line — gearing near 80% was tolerable at 2% interest rates and lethal after they climbed. Ask of any gearing figure: how stable are this firm's cash flows, and what happens to the interest bill if rates move? A supermarket with steady weekly cash can carry gearing a housebuilder cannot.
A utility has non-current liabilities of £300m and total equity of £200m. Capital employed = £300m + £200m = £500m. Gearing = 300 ÷ 500 × 100 = 60% — highly geared. At 6% interest, the annual interest bill = 0.06 × £300m = £18m. Against operating profit of £50m that is manageable (36% of profit). But if profit halves to £25m, the unchanged £18m bill consumes 72% of everything the business earns — before tax, dividends or investment. The gearing ratio didn't change; the margin for error did. That interaction between gearing and profit volatility is the analysis the exam pays for.
DataHuman resources — the competitiveness numbers hiding outside the accounts
Financial statements measure the results of people's work but not the people. Edexcel gives you three HR gauges. Labour productivity = output per period ÷ number of employees: the single biggest driver of unit labour costs, and the gap behind most price competitiveness stories. Labour turnover = staff leaving in a year ÷ average employed × 100; UK hospitality routinely runs at roughly double the all-economy average, and every percentage point has a price — recruitment, training, and the months a newcomer spends below full speed, with replacement costs commonly put in the thousands of pounds per leaver. Absenteeism = days lost ÷ working days available × 100: partly sickness, partly a thermometer for morale and management.
The strategies the spec names map onto causes. Financial rewards (pay, bonuses, piece rates) work where effort is measurable and money is the binding constraint. Employee share ownership aligns staff with owners — Richer Sounds handed majority ownership to an employee trust in 2019, the John Lewis model. Consultation and empowerment attack the deeper causes of quitting and absence: powerless, unheard staff leave, or stay and disengage. The evaluative link back to the ratios: HR failure arrives in the accounts eventually — low productivity as bloated costs, high turnover as recruitment spend, absence as overtime — so the ‘soft’ numbers are early warnings of the ‘hard’ ones.
A 20-branch café chain employs an average of 220 staff and serves 44,000 customers a week: productivity = 44,000 ÷ 220 = 200 customers per employee per week. Over the year, 33 staff leave: labour turnover = 33 ÷ 220 × 100 = 15%. If each leaver costs roughly £3,000 in recruitment, training and lost output, turnover costs 33 × £3,000 = £99,000 a year — call it £100k. A £40,000 investment in supervisor training and flexible rotas that cut turnover to 10% (22 leavers, £66,000) saves £33,000 a year against £40,000 spent — marginal in year one, clearly positive once the improvement persists. HR decisions are investment appraisals wearing casual clothes.

ExamWhat examiners want
Ratio questions on Papers 2 and 3 follow a strict ritual: formula, substitution, answer with units, then — the mark most dropped — interpretation against a benchmark. ‘Gearing is 60%’ scores; ‘gearing is 60%, roughly double the level a lender would call comfortable, and interest already consumes a third of operating profit’ scores properly. Learn the Edexcel formulae exactly: capital employed = non-current liabilities + total equity appears in BOTH ratios, and mixing in current liabilities is the classic error.
On bigger evaluate questions, the top-band move is connecting the ratios into one story: high gearing plus falling ROCE plus rising interest rates is a squeeze you can narrate, not two isolated numbers. Bring the limitations honestly — accounts are historical, window-dressable, and blind to brand and people — and when the case gives HR data, use it as the leading indicator it is: rising labour turnover this year is next year's cost line. Examiners' reports repeatedly praise candidates who treat the financial and human numbers as one integrated picture of competitiveness rather than two separate topics.
