External Influences: Economy and Legislation (Edexcel 9BS0 2.5)
No business controls the economy or the law, but both reshape costs and demand constantly. Section 2.5 covers economic influences — interest rates, inflation, exchange rates and taxation — alongside legislation and the competitive environment. Recent UK policy changes give you unusually strong real-world material for application marks.
Economic influences: interest rates, inflation and exchange rates
Interest rates change the cost of borrowing and the reward for saving. The Bank of England cut its base rate to 4% in August 2025 after holding it high to squeeze inflation, easing pressure on indebted firms.
Worked example: a firm with a £150,000 variable-rate loan at 7.5% pays 150,000 × 0.075 = £11,250 interest a year. If its rate falls one percentage point to 6.5%, interest drops to £9,750 — a saving of £1,500 that flows straight to net profit. Rate changes also work through customers: cheaper mortgages leave households more to spend on furniture, cars and eating out.
Inflation raises input costs and erodes real incomes; UK CPI stayed uncomfortably near 3.5–4% through much of 2025, keeping cost pressure on food and hospitality businesses. Exchange rates cut both ways: a weaker pound makes UK exports cheaper abroad but raises the cost of imported materials, so the winners and losers depend on where a firm buys and sells.
Taxation and legislation: the 2025 cost shock
Government policy moved business costs sharply in April 2025, and examiners expect you to know it. Employer National Insurance contributions rose from 13.8% to 15%, while the threshold at which employers start paying fell from £9,100 to £5,000 per worker — a double hit that made every job, especially part-time roles, more expensive. At the same time the National Living Wage rose to £12.21 an hour. Labour-heavy sectors absorbed the worst of it: J D Wetherspoon estimated the combined changes would add roughly £60m a year to its costs, and responded with price rises and continued investment in labour-saving kitchen and ordering technology.
Beyond employment costs, the specification expects working knowledge of:
- Consumer protection — the Consumer Rights Act 2015 requires goods to be of satisfactory quality and fit for purpose.
- Health and safety — duties on employers under the Health and Safety at Work Act.
- Competition law — the Competition and Markets Authority can block mergers and fine cartels.
Responding to external change
Analysis marks come from tracing an external change through to a specific business; evaluation marks come from judging the response. The main strategic options:
- Pass costs on through prices — works where demand is price-inelastic, dangerous in fiercely competitive markets.
- Absorb costs and accept thinner margins — sustainable only for firms with margin to spare.
- Substitute technology for labour — self-order screens and automation, a visible response across UK hospitality since the 2025 NIC rise.
- Hedge or relocate sourcing against exchange-rate swings.
- Fix borrowing costs with fixed-rate finance when rates look likely to rise.
The competitive environment shapes which option is open: a discount retailer facing the same wage bill as a premium rival has far less pricing power. Top answers weigh short-term fixes against long-term positioning — a price rise protects this year’s margin but can hand customers to competitors for good, while automation costs cash now and pays back over years.
Key terms
Practice questions
A business has a £150,000 variable-rate loan charged at 7.5% a year. Calculate the annual saving if the rate falls to 6.5%. [4 marks]
Model answer guidance: Interest at 7.5% = 150,000 × 0.075 = £11,250. Interest at 6.5% = 150,000 × 0.065 = £9,750. Saving = £11,250 − £9,750 = £1,500 a year. Show both interest figures — the subtraction alone does not display the method.
Explain one way a fall in interest rates might increase demand for a UK furniture retailer's products. [4 marks]
Model answer guidance: Identify the household channel: lower rates cut mortgage payments and make credit cheaper. Develop the chain — households have more discretionary income and big-ticket purchases bought on finance become more affordable, so postponed furniture purchases go ahead, lifting the retailer's sales volume.
Discuss how a pub chain might respond to a rise in employer National Insurance contributions. [8 marks]
Model answer guidance: Options: raise selected prices where demand is least sensitive; redesign rotas and cut hours; invest in self-order apps and kitchen technology to reduce staff hours per customer, as Wetherspoon has done. Each carries risk — price rises in a value-led market lose custom, cutting staff harms service. Conclude that a mix, weighted towards productivity investment, protects the model best over time.
Assess the likely impact of a strong pound on a UK manufacturer that exports most of its output to Europe. [10 marks]
Model answer guidance: Negative: its goods become dearer in euros, so European buyers may switch to local rivals, squeezing volume or forcing the firm to cut its sterling price and margin. Offset: imported materials and components become cheaper, lowering costs. Judgement depends on import content and demand sensitivity — a manufacturer importing half its inputs with a differentiated product suffers far less than one selling a commodity with UK-sourced inputs.
Evaluate whether rising labour costs are the most significant external influence on the profits of UK hospitality businesses such as J D Wetherspoon. [20 marks]
Model answer guidance: Build the case for: hospitality is labour-intensive, so the April 2025 combination of a 15% employer NIC rate, a £5,000 threshold and the £12.21 National Living Wage hit margins directly — Wetherspoon put the cost near £60m a year, large against its profit base, and unlike a demand dip the cost is permanent and legally unavoidable. Build the case against: interest rates shape both consumer spending and debt costs, food and energy inflation moved input costs sharply through 2024–25, and weak consumer confidence suppresses visits regardless of the wage bill; unlike wage rises, these can also move favourably. Evaluate by combining them: labour costs are the largest single controllable pressure and fall hardest on value operators with thin margins, but profits ultimately depend on the gap between costs and revenue, and revenue is set by the economic cycle. A strong conclusion argues labour costs are the most significant influence on the cost side, while accepting that a consumer downturn would do greater total damage — then commits to a justified position for a business like Wetherspoon, whose scale allows technology substitution smaller rivals cannot afford.
Examiner tips
- Learn the April 2025 figures cold — 15% employer NICs above a £5,000 threshold and a £12.21 National Living Wage — because precise, dated facts earn application marks generic statements never reach.
- Trace every external change through a two-step chain to profit (rates fall → mortgages cheaper → discretionary spending rises → sales volume up) rather than jumping straight to the conclusion.
- In 20-mark evaluate questions, weigh the influence you were given against one credible alternative and commit to a conclusion that fits the specific business in the case.
