Critical illness additional payments: how much cover remains afterwards?

Some critical illness policies pay a smaller amount for specified conditions without paying the full main benefit. The wording may call these additional payments or partial payments, but the label alone does not establish what happens to the remaining cover.

Before comparing policies, identify the condition definition, payment calculation and effect on any later claim.

Distinguish the main benefit from other payments

A policy can contain several types of benefit with different triggers. The main critical illness amount, an additional-condition payment, children's cover and other support benefits may each follow separate rules.

Legal & General's critical illness product information provides an example of additional payments that preserve the main lump sum, subject to the policy terms. That feature should not be assumed for every insurer, product version or kind of partial payment.

Use the schedule and conditions supplied when the policy was accepted. A newer sales page may describe improved or simply different terms.

Read the percentage and the cap together

Consider a fictional benefit paying 25% of the insured amount, capped at £20,000. With £60,000 main cover, the calculated payment is £15,000. With £120,000 main cover, 25% would be £30,000, but the cap limits payment to £20,000.

These invented terms illustrate the calculation rather than describing a current product. The larger main policy does not necessarily produce a proportionately larger payment for every additional condition.

Check whether the percentage applies to the original cover, the amount at the claim date or another defined value. Decreasing and increasing policies can make that distinction significant.

Confirm whether the payment reduces anything else

Ask whether receiving the additional benefit reduces the main amount, ends part of the policy or affects eligibility for another claim. Establish whether there are restrictions for related conditions or repeated claims.

If a hypothetical £15,000 additional payment leaves £60,000 main cover intact, record both facts. If another contract instead reduces the main amount by £15,000, the remaining amount would be £45,000. Those are materially different arrangements even though the first payment is identical.

Do not describe either result as universal. Obtain the insurer's explanation using the specific policy wording.

A diagnosis name is not the complete trigger

The policy may require a specified severity, treatment, test result or other criterion. Everyday descriptions of an illness can be broader than the insured definition.

Ask the insurer or adviser to identify which definition applies. Supply accurate medical information through the appropriate secure process, and allow the insurer to obtain the evidence it requires.

If a claim is declined or paid at a different level from expected, request the reason and the clause used. A comparison based solely on the number of conditions listed would not have explained this distinction before purchase.

Put the payment into a practical budget

Suppose a fictional £15,000 payment is received and £4,000 is needed for immediate adjustments at home. The remaining £11,000 could meet a £1,100 monthly shortfall for ten months, ignoring interest, inflation and other expenses.

That calculation helps assess what the money can do. It does not mean the policy is designed to replace income for ten months, or that another payment will follow when the reserve is used.

Keep any ongoing income protection, sick pay or other support in a separate line with its own conditions. Avoid counting an uncertain future claim as money already available.

Compare benefits that matter to the household

A useful review considers the main insured amount, relevant definitions, additional payment limits, survival conditions where applicable, exclusions and the impact of a claim on future cover.

Ask the adviser to explain material differences between the accepted quotes and why they matter for the stated need. More listed benefits do not automatically make a policy preferable if the central cover is unsuitable or unaffordable.

Keep a concise summary with the full policy documents. It should help a family member find the insurer and understand that a claim needs assessment, without trying to replace the contractual wording.
