2.2 The Need for and Benefits of Insurance

Why People and Organisations Buy Insurance

Insurance does not stop losses from happening - a sprinkler does not stop a fire starting, and a motor policy does not prevent a collision. What insurance does is transfer the financial consequences of those losses to an insurer, in exchange for a known, manageable premium. That single function produces benefits at three levels.

Benefits for the Individual

For private individuals, the core benefits are psychological and financial:

• Peace of mind - the removal of anxiety that would otherwise accompany the ownership of assets and the carrying of responsibilities.
• Financial security - a fire, flood, or serious illness can be financially ruinous; insurance restores the insured to the position they were in before the loss.
• Certainty - the uncertain large loss is replaced by a certain small premium, which a household can budget for.
• Compliance - motor insurance is a legal requirement in the UK, and buildings insurance is usually a condition of a mortgage.

Benefits for Business

For firms, insurance is not a luxury - it is part of the operating system of the enterprise.

• Business continuity - property and business interruption cover allows a firm to rebuild and keep trading after a major loss rather than fail outright.
• Protection of assets and earnings - stock, premises, plant, and receivables are protected, as is the profit stream that depends on them.
• Access to credit and finance - lenders routinely require property to be insured as a condition of a loan; without cover, finance may be refused or withdrawn.
• Reduction in the cost of risk - by combining risk improvement with transfer, the total cost of risk (premium plus retained losses plus risk-management costs) is lowered.
• Support for investment and growth - investors and shareholders are more willing to back a business whose downside is capped.
• Legal compliance - employers' liability insurance is compulsory for most UK employers under the Employers' Liability (Compulsory Insurance) Act 1969.

Benefits for the Economy and Society

At the macro level, insurance is a cornerstone of a modern economy.

• Spreads and reduces the cost of risk - by pooling many independent exposures, insurers make the cost of risk predictable and far lower for each participant than self-insurance would be.
• Encourages risk reduction - insurers impose conditions, warranties, and discounts that drive safer behaviour (burglar alarms, sprinklers, driver telematics).
• Mobilises savings - long-term life and pension insurance collects and invests large pools of capital, funding infrastructure and corporate investment.
• Supports international trade - marine, aviation, and political-risk insurance allow goods and capital to move across borders that would otherwise be too hazardous to finance.
• Balance of payments and employment - the UK insurance industry is a net exporter, generating premium income from overseas business and employing around 300,000 people.
• Tax contribution - insurers pay corporation tax and insurance premium tax (IPT), and their employees pay income tax and National Insurance.

Loss-Control and Risk-Improvement Services

Insurers do more than pay claims. Through their surveyors, engineers, and risk consultants they provide loss-control services that help policyholders prevent losses in the first place. Examples include fire protection surveys for factories, fleet driver training for motor clients, and cyber-security assessments for commercial policyholders. This is a genuine win-win: the policyholder suffers fewer disruptions, and the insurer pays fewer claims.

What Insurance Does Not Do

It is important to be clear about the limits of insurance. Insurance does not eliminate risk, restore life or limb, or compensate for sentimental value. It compensates financial loss, no more and no less. Keeping this in mind explains why insurance is always paired with risk control in a well-designed programme.

The Cost of Risk and the Insurance Trigger

A useful concept that ties the previous section to this one is the cost of risk - the total cost to an organisation of living with its risks. It comprises insurance premiums, retained losses (deductibles and uninsured losses), risk-control expenditure (alarms, training, security), and the administrative cost of running the risk-management function. Insurance is worthwhile only when it reduces the total cost of risk, or when the losses it covers would otherwise threaten the survival of the organisation.

Most private insurance operates on the principle of indemnity - restoring the insured to the position they were in immediately before the loss. Life assurance is the main exception, because a life cannot be valued in money, so a fixed sum assured is paid. Understanding which principle applies helps explain why general insurance covers the actual loss suffered, while life policies pay out an agreed amount regardless of financial loss.

Insurance as a Pillar of Civil Society

Compulsory insurances - motor third party, employers' liability, and (in practice) buildings cover as a mortgage condition - exist because the consequences of uninsured loss fall on innocent third parties and on the state. By making cover compulsory, society ensures that victims of road accidents and injured workers are compensated even when the responsible party cannot pay. This social function is why insurance is described not just as a private contract but as a pillar of a functioning economy.
