UK Mortgage Protection Insurance: What You Need (and What You Don't)

This guide is general information and not regulated protection advice. Protection products are sold through FCA-authorised advisers who'll assess your specific cover needs. Your home may be repossessed if you do not keep up repayments on your mortgage.

The three main protection products

Life insurance (term)

Pays out a lump sum (or set of lump sums) if you die during the policy term. Most mortgage-aligned policies use "decreasing term" cover - the payout decreases over time, matching the typical mortgage balance reducing through repayment. Cheapest of the three protection types. Pays nothing if you survive the term.

Critical illness cover

Pays a lump sum on diagnosis of specified illnesses - cancer, heart attack, stroke, multiple sclerosis, and others. Each insurer publishes a list of covered conditions (typically 50+ for modern policies). Common buy: combined Life + Critical Illness (CIC) on a single policy paying out on the first event of either.

Income protection

Pays a monthly income (typically 50-65% of pre-tax salary) if you're unable to work due to illness or injury. Continues paying until you return to work, hit the policy's expiry (often retirement age), or reach a benefit cap. The most valuable protection for most working-age earners - and the most under-bought.

What employer cover does and doesn't include

Many UK employers provide some basic protection: death-in-service benefit (typically 2-4x salary), sometimes Group Income Protection, sometimes Group Critical Illness. Always check your employer's benefits document before buying additional cover - what you have may reduce what you need to buy yourself.

But employer cover has limits: it stops when you change jobs, the cover amount may be capped, definitions of "unable to work" may be stricter than private cover, and Statutory Sick Pay alone (currently £116.75/week in 2026) won't cover most UK mortgage payments.

Typical costs (2026 indicative)

Smokers typically pay 30-50% more. Health conditions (high BMI, asthma, mental health history, family history of major illness) often loadings of 20-200%. Older applicants and high-risk occupations pay materially more.

Which combinations suit which situations

Single, no dependants, modest mortgage

Income protection is the priority - protects your income (and therefore mortgage payment) if you can't work. Life insurance is much less important; your mortgage would be repaid from the sale of the home and there are no dependants who need the cover.

Couple with dependants, joint mortgage

Joint life cover protects the mortgage. Critical illness cover adds protection against the financially-disrupting illnesses. Income protection for whichever partner is the primary earner. This is the most common comprehensive protection bundle for UK home-buying couples.

Self-employed

Income protection is essential - self-employed have no employer-provided sick pay or death-in-service cover. Often valuable to have both Income Protection and Critical Illness Cover. Life cover for any dependants.

Older buyers / second-property buyers

Cover requirements shift - dependants are usually grown, mortgage often shorter, but premiums are higher. Sometimes a decreasing term life policy plus modest CIC is enough. Take advice.

Common mistakes

• Buying mortgage payment protection insurance (MPPI) sold by the lender at completion. Lender-tied PPI products are usually worse value than properly-advised protection bought separately. Take the time to compare via a broker.
• Under-insuring income protection. SSP doesn't cover a UK mortgage. Without income protection, savings have to bridge any extended sickness absence.
• Treating death-in-service as enough cover. It evaporates when you change jobs. Standalone life cover is portable.
• Not disclosing material health information on application. Misrepresentation can void cover at claim. Always be honest on the application.
• Choosing decreasing-term when you want level cover. Decreasing covers the mortgage; level covers fixed-need amounts like child education or income replacement.
• Forgetting to put life cover in trust. Without a written-in-trust, the payout falls into your estate and may attract IHT or be tied up in probate.

Putting cover in trust

Most UK life insurance is best held in trust. A trust ensures the payout goes directly to your nominated beneficiaries without going through probate, avoiding delays and protecting against UK Inheritance Tax (the payout doesn't form part of your estate). Trusts are typically free to set up at the time of policy application via the insurer's standard trust form.

Buying through your mortgage broker

Most UK mortgage brokers also advise on protection. The advantages: they know your mortgage circumstances and dependants situation, they can size cover to match the mortgage, and the advice is typically free (commission-paid by the insurer). The same broker session covers both the mortgage and the protection needs.

What to do next

Match with a UK mortgage broker who'll also advise on protection. Free, FCA-authorised, qualified to give both mortgage and protection advice. They'll model your specific situation rather than selling a one-size-fits-all bundle.
