Business Regulation

Promoting Competition

Competition keeps prices down and quality up, so most UK regulation of business aims to protect it.

Preventing Anti-Competitive Practices

UK competition law bans two things: agreements between firms that restrict competition, such as price fixing in a cartel, and a dominant firm abusing its position, such as through predatory pricing (unit 4.2.1). Firms that break the law can be fined, and individuals involved in a cartel can go to prison.

Controlling Mergers and Takeovers

A merger between rivals removes a competitor. The Competition and Markets Authority (CMA) can review a merger where the business being bought has UK turnover above £100 million, or where the merged firm would supply at least 25% of a product in the UK.

If a deal would substantially lessen competition, the CMA can block it, as it did with Sainsbury's and Asda in 2019, or approve it only if the firms sell off parts of the business.

Privatisation

Privatisation: transferring a business from public ownership to private ownership, usually by selling shares.

BT, British Gas and Royal Mail are UK examples. The aim is to bring in the profit motive and, where possible, competition:

• Efficiency: private owners want profit → managers cut waste and costs → lower prices or better service for customers.
• Government finances: the sale raises money once → the state no longer covers the firm's losses.

The risk is that a privatised natural monopoly is still a monopoly. Without competition the profit motive can push prices up and quality down, which is why such firms are regulated.

Regulating Natural Monopolies

A natural monopoly, such as a gas or electricity network, cannot be made competitive by breaking it up (unit 4.2.1). Instead an industry regulator controls what it does. Ofgem, for example, limits how much the companies that own the energy networks can charge.

Regulators use two main tools:

• Price caps: prices may rise by no more than inflation minus a figure, X, for efficiency savings (often written RPI − X) → the firm keeps any profit from beating X → it has an incentive to cut costs.
• Quality and performance targets: fines for missing targets such as supply cuts or complaints → the firm cannot raise profit by letting service slip.

How well this works depends on:

• Information: the firm knows its costs far better than the regulator, so X may be set too low.
• Regulatory capture: a regulator that grows too close to the firms it oversees may start to serve their interests (unit 4.2.3).

Protecting Consumers

Consumers know less about a product than the firm selling it, so the law sets minimum standards. Under the Consumer Rights Act 2015, goods must be of satisfactory quality, fit for purpose and as described, and buyers can claim a refund, repair or replacement if they are not.

The Digital Markets, Competition and Consumers Act 2024 went further. It bans fake reviews and drip pricing, where extra charges appear only late in the buying process. Since April 2025 the CMA can decide for itself that a firm has broken consumer law and fine it up to 10% of its global turnover.

• Consumers: clear prices and honest reviews → they can compare offers properly → better choices and fewer bad buys.
• Firms: compliance costs money → but honest firms no longer lose sales to rivals who mislead.

The Work of the Competition and Markets Authority

Competition and Markets Authority (CMA): the UK government body that enforces competition and consumer law.

Its main jobs are to:

• review mergers and block or change harmful ones
• investigate and fine cartels and abuse of dominance
• study whole markets that seem not to be working, and order changes
• enforce consumer protection law

In 2025, after the Oasis reunion ticket sale, the CMA secured commitments from Ticketmaster to give fans clearer pricing information and label tickets accurately.

Impact of EU Competition Policy

The EU has its own competition rules, enforced by the European Commission. Since Brexit they no longer apply inside the UK, where UK law does the same job. They still matter to UK businesses:

• UK firms that trade in the EU: a cartel or abuse of dominance that affects EU markets can be investigated and fined by the Commission → UK exporters must follow EU rules as well as UK ones.
• Large mergers: the EU no longer reviews deals on the UK's behalf → a global merger can need approval from both the CMA and the Commission → more cost and delay, and a risk the two decide differently.

Employee Protection

Workers usually have less bargaining power than their employer, especially where it is a monopsony (unit 4.2.1). UK law sets minimum standards, including:

• The National Minimum Wage and National Living Wage, a legal floor on hourly pay.
• The Equality Act 2010, which bans discrimination on grounds such as sex, race, disability and age.
• Health and safety law, which makes employers manage risks at work.
• Limits on working time and protection from unfair dismissal. The Employment Rights Act 2025 is adding further rights in stages.

The effects of employee protection:

• Workers: higher minimum pay and safer conditions → higher real incomes and better wellbeing.
• Firms: higher labour and admin costs → lower margins or higher prices, though better-treated staff may stay longer and work harder.

The overall effect depends on:

• Firm size: the paperwork weighs more heavily on a small business than a large one.
• The labour market: where employers have monopsony power, a minimum wage can raise pay without cutting jobs.
