AIG Life Ltd has been writing UK protection insurance for generations and sits among the major providers on our whole-of-market comparison panel. This 2026 review covers AIG Life's critical illness cover proposition — claims performance, features, pricing, underwriting stance and who it's the right choice for.
About AIG Life
AIG Life Ltd is an FCA-authorised UK protection insurer. Its critical illness cover sits on the whole-of-market panel that UK FCA-authorised advisers quote from, so applicants can access AIG Life pricing whether they go direct or via an adviser.
AIG Life critical illness cover — key facts
- Entry age: 18–77 years.
- Max cover amount: £5 million.
- Max term: 50 years.
- Headline premium: £5/month from age 25.
- 2024 claim-paid %: 94.0%.
- USP: YourLife Plan with free Smart Health (24/7 GP, second opinion, online fitness, mental health support, nutrition consults for whole household).
Features included
Smart health included free, wellbeing support, relationship support, real rewards discount scheme, flexible premium payment.
In our adviser panel's view these features materially differentiate AIG Life from budget online-only providers. The feature that most often justifies choosing AIG Life over a cheaper competitor is Smart Health included free — especially for applicants who'll actually use it.
Pricing — is AIG Life competitive?
AIG Life sits in the low-mid tier of UK protection pricing. For a healthy non-smoker aged 30 buying £250,000 of critical illness cover, our adviser panel typically sees AIG Life priced around £5/month from age 25 — in line with the major-brand competitive set.
Where AIG Life tends to outperform on price:
- Applicants matching this underwriting stance: competitive for over-50s and joint-life policies.
- Mid-to-large sums assured (£250k+).
- Standard-term cover (20–30 years).
Where AIG Life is not usually the cheapest:
- Very small sum-assured policies (<£100k) — budget online-only insurers typically undercut on these.
- Very old or very young applicants at the extremes of the entry-age range.
Claims performance
AIG Life paid 94.0% of critical illness cover claims in 2024 — a strong figure against the UK industry average of ~98% for term life, ~91% for critical illness, ~90% for income protection.
Declined claims across the whole UK market are driven overwhelmingly by:
- Non-disclosure at application — the biggest cause by far. Honest, complete answers at application is the single biggest determinant of whether your claim pays.
- Definition mismatch — the claim doesn't meet the policy's wording. Particularly common on older critical illness definitions.
- Policy lapse — missed premium payments causing the policy to be cancelled before the claim event.
Critical illness definitions — what does AIG Life actually cover?
AIG Life's critical illness policy covers 52 conditions in its core definition, with additional conditions available as optional upgrades. Core conditions include:
- Cancer — treated in accordance with ABI+ definitions, pays on diagnosis of invasive cancer (some early-stage cancers pay a partial sum).
- Heart attack — on diagnosis meeting ABI definition (troponin, ECG changes).
- Stroke — permanent neurological deficit at 24 hours or more.
- Multiple sclerosis — diagnosis with persistent neurological abnormalities for at least 3 months.
- Major organ transplant, kidney failure, motor neurone disease, Parkinson's disease (under age 60/65), dementia (over 55).
Partial payment / additional conditions: AIG Life pays partial sums on less-severe conditions such as low-grade prostate cancer (typically 25%), Carcinoma in situ of the breast (typically 25%), and specific severity grades of Crohn's, UC and severe burns. Check the policy's Key Facts document for full 2026 definitions.
Underwriting — who will AIG Life price competitively?
AIG Life's underwriting profile is: competitive for over-50s and joint-life policies.
In practice that means:
- Healthy non-smokers, age 25–45: competitive; often within 5–10% of the cheapest market rate.
- Smokers: AIG Life's smoker loading is typically in line with the major-insurer average.
- Pre-existing conditions: underwriting varies sharply by condition — our advisers pre-underwrite with AIG Life and two or three competitors in parallel to find the favourable home.
- Over-50s: standard — not a specialist in this segment.
Who is AIG Life critical illness cover best for?
- Applicants who value YourLife Plan with free Smart Health (24/7 GP, second opinion, online fitness, mental health support, nutrition consults for whole household).
- Applicants who'll actually use Smart Health included free.
- Underwriting profile: competitive for over-50s and joint-life policies.
- Sum assured in the £100k–£5 million range.
- Term in the 10–50 years range.
Who should look elsewhere?
- If you want the cheapest possible budget headline and have simple requirements: a budget online-only insurer may be cheaper.
- If your medical history falls outside AIG Life's favoured underwriting profile: another insurer may price more competitively.
- If you need cover over £5 million or beyond 50 years: another insurer with a higher cap.
How to get AIG Life critical illness cover
AIG Life policies are available direct from AIG Life and via FCA-authorised advisers. Going via an adviser has three advantages:
- You see AIG Life alongside every other major UK insurer in one sitting.
- The adviser pre-underwrites with AIG Life and competitors, so you see realistic not just illustrative quotes.
- The adviser-channel price is the same as (or better than) direct.

If you're cancelling because you've found a cheaper alternative, make sure the new policy is in force before cancelling the old one.
