Life Insurance With A Pre Existing Condition
TL;DR
UK life insurance is available to applicants with pre-existing conditions in the vast majority of cases. The wrong first move — applying to a single insurer whose underwriting doesn't favour the history — can result in a decline that stays on industry records, so the route most likely to secure cover on the best terms is a broker-led comparison across insurers known to be receptive to this kind of application. Where a query includes "pre", "existing", and "condition", the guide below works through likely underwriting treatment, disclosure requirements and impact on cover.
Disclosing pre-existing conditions on the application
The disclosure rule that matters here is the duty of fair presentation. In relation to pre-existing conditions, that means past diagnoses, ongoing medication, GP notes, specialist referrals, family history, and any investigations still in progress all need to be on the application. Leaving borderline cases off the form — because "it was years ago" or "nothing came of it" — is the single biggest cause of later claim problems.
If something is borderline, disclose it. Insurers far prefer a declared history they can underwrite (and possibly load or exclude) to an undisclosed one they discover at claim stage through GP records under the Access to Medical Reports Act.
Common exclusions and how they apply
Even where cover is in force, claims linked to pre-existing conditions can be affected by specific policy exclusions. Typical UK exclusions fall into three groups: pre-existing conditions not disclosed at application, high-risk activities named in the schedule, and deaths within a defined suicide or self-harm period (commonly 12–24 months from policy start).
The exclusion set on your policy is specific to you — it's assembled during underwriting based on declared history. Two applicants buying the same branded policy can have very different exclusion wording on their individual schedules, so the comparison that matters is your schedule, not the marketing page.
How a claim is assessed
UK insurers assess claims involving pre-existing conditions against three things: continuity of premiums, accuracy of the original application, and whether the cause of claim falls inside any policy exclusion. The ABI's claims-paid ratio for term life insurance sits above 97%, and the rejected minority almost always cluster around non-disclosure rather than genuine ambiguity.
Genuine claims that are rejected almost always share one of two features: a pattern of non-disclosure that changed the risk, or a claim that falls inside a named exclusion. Speaking to an adviser before you apply tends to prevent both.
How this plays out in practice
An applicant declined by one mainstream insurer for pre-existing conditions is not uninsurable. The same application, routed to an insurer with a more favourable underwriting stance on the specific history, often results in cover at standard or modestly-loaded rates. What matters is where the application is sent first — a formal decline sits on the industry database and can complicate later attempts.
Start dates, waiting periods, and pre-existing conditions
Policies run from the start date on the schedule, not the application date. In relation to pre-existing conditions, the timing rules that bite most often are the standard 12–24 month suicide exclusion, the gap between application and on-risk if underwriting takes longer than expected, and any policy lapse caused by a missed direct debit.
The single most important operational rule: don't let the existing policy lapse while waiting on new cover. A brief period of paying two premiums costs little; a gap in cover that coincides with any claim event has no remedy.
Frequently asked questions
Is there a waiting period for cover when pre-existing conditions is declared?
For fully-underwritten policies, no — cover goes on risk from the start date. Guaranteed-acceptance over-50s plans have a waiting period (commonly 12–24 months) during which only accidental death is fully covered, whether or not pre-existing conditions is present.
Do I have to tell the insurer about pre-existing conditions when I apply?
Yes — UK law requires you to make a "fair presentation" of material facts. Anything a reasonable insurer would want to know about pre-existing conditions should be disclosed, including past diagnoses, ongoing treatment, medication and family history.
How much extra does pre-existing conditions add to life insurance cost?
Loadings for declared medical history in the UK range from about +25% of standard rates for mild or historical cases up to +200% or more for active conditions. Some insurers apply no loading after a clear period; others decline outright. The spread is exactly why a multi-insurer comparison matters here.
