Emergency funds and health shocks

Financial planning for illness usually focuses on treatment costs, and for most households the larger exposure is the income that stops.

The two exposures

Which require different preparation.

Direct costs: treatment, medication, dental and optical, travel to appointments, equipment, home adaptations and childcare during treatment.

These vary enormously by health system, from negligible to catastrophic.

Indirect costs: lost earnings for the ill person, lost earnings for whoever cares for them, and the additional expenses of being at home and unwell — heating, food, transport.

Studies of the financial impact of serious illness consistently find indirect costs to be the larger component in countries with public healthcare, and a substantial component everywhere.

Sizing an emergency fund

General guidance and its limits.

The common advice is three to six months of essential expenses.

The appropriate figure depends on income stability, sick pay entitlement, household composition and existing insurance.

Employees with generous occupational sick pay need less; self-employed people with none need considerably more.

Single-income households need more than dual-income ones.

The practical starting point is calculating essential monthly expenditure — housing, utilities, food, transport, minimum debt payments, insurance — which is generally lower than total spending and is the figure that matters.

Building it

Where perfection is the enemy.

A small fund is dramatically better than none: research on financial resilience consistently finds that a modest buffer prevents the cascade into expensive credit that turns a temporary problem into a lasting one.

Automate transfers on payday rather than saving what is left.

Keep it accessible, in an instant-access account separate from everyday banking, since accessibility is the point.

Do not invest an emergency fund, since the money is needed exactly when markets may be down.

And prioritise it above overpaying low-interest debt, and below clearing high-interest debt, which is generally the right order.

What to check before you need it

The preparation that costs nothing.

Employer sick pay: the rate, the duration and whether it is contractual or discretionary.

Whether the employer provides income protection, critical illness or private medical cover as a benefit, which many do and few employees know.

Existing insurance policies, including anything bundled with a mortgage, bank account or credit card.

State provision, particularly if self-employed.

Pension arrangements, including whether contributions continue during sickness and whether ill-health early retirement provisions exist.

And whether your household could manage on one income, which is the scenario most worth modelling.

Insurance worth considering

Where the case is strongest.

Income protection, which pays a proportion of income after a deferred period and until recovery or retirement, is the product most closely matched to the actual risk and is under-bought relative to life insurance.

The deferred period is the main lever on cost — a longer wait, matched to your sick pay and savings, substantially reduces premiums.

Critical illness cover, which pays a lump sum on diagnosis of specified conditions, with the definitions being the entire product — reading them matters more than comparing prices.

Life insurance, particularly with dependants or a mortgage.

And private medical insurance, whose value depends heavily on the health system you are in.

Buying through an employer scheme is frequently substantially cheaper than individually.

When the shock arrives

The order of actions.

Claim everything you are entitled to promptly, since backdating is limited — sick pay, benefits, insurance policies, and any employer schemes.

Get a benefits check from an independent advice service rather than assuming ineligibility, since take-up is consistently below eligibility.

Contact creditors early, since hardship processes exist and options narrow after missed payments.

Prioritise essential bills — housing, energy, council tax — over unsecured debt, which is the opposite of what pressure suggests.

Ask the treating team about welfare rights support, which many hospitals and condition-specific charities provide.

And apply for charitable grants, which exist for many conditions and are rarely approached.

The costs people forget

Which accumulate quietly.

Travel and parking for appointments, which for repeated treatment is substantial and for which reimbursement schemes exist in some systems.

Childcare during appointments.

Heating, since being at home unwell costs more.

Food, since cooking becomes harder.

Equipment and adaptations.

Prescription, dental and optical costs, where exemptions exist for some conditions and are unclaimed.

And the cost of a partner reducing hours to provide care, which is frequently the largest single item and is rarely counted.
