There is no single best life insurance and critical illness cover provider: which suits you depends on what you need the cover to do. Seven insurers’ current documents are set side by side below, on the terms that differ most: how the plan is built, the conditions listed, smaller payments and children’s cover.
Price is left out because it depends on your age, health and the amount you choose. For a quote built on your own details, an FCA-authorised broker can set offers from several insurers next to each other and ask how each would view your health; complete the form on this page to be introduced to one, at no cost.
How do you compare life and critical illness cover providers?
Two quotes for one sum can describe different cover. The Association of British Insurers (ABI) sets a floor in its Guide to Minimum Standards for Critical Illness Cover (September 2022, updated April 2023): cancer, heart attack and stroke are the core conditions that all policies must include, covered to at least the Guide's standard model wordings.
Each document is dated as printed; terms change, so check the version you are offered. What adding critical illness cover to a life policy does is explained in life and critical illness cover, one of our critical illness and income guides.
How is each insurer’s plan built?
| Insurer and document | How the cover is set up | After a full critical illness payment |
|---|---|---|
| Aviva, Life Insurance+ summary (AL50001 02/2026) | Life and critical illness cover is one choice within the plan | "A successful claim under a critical illness condition for the life covered will pay the full cover amount and end the policy." |
| Legal & General, policy summary (QGI14786 2026/10, direct) | Critical illness cover is added "alongside your Life Insurance as a separate policy" | "We'll pay out your amount of cover in full once. After this happens, the policy will end" (Legal & General’s critical illness cover) |
| Zurich, key features (NP720500009 02/25, still linked from its critical illness page in September 2026) | "Life Cover and Critical Illness" is one type of cover; a different sum assured for each needs "two separate policies" | "After which, your policy will end." |
| LV=, Life and Critical Illness summary (April 2026) | One policy paying "if you die or, if earlier you are diagnosed with a critical illness" | A claim ends the policy, unless it was for an additional payment condition or for children’s cover |
| Scottish Widows, Protect summary (January 2026) | Life with Critical Illness Cover pays on death or a covered diagnosis, "whichever happens first before the policy’s end date" | "If we pay out the full cover amount, we’ll stop collecting your monthly payments and the policy will end." |
| Royal London, Critical Illness Cover plan details (July 2025, adviser site) | A critical illness plan; Royal London’s consumer page says it is "Available through an independent financial adviser" | "We’ll pay out once and then your cover will stop." (Royal London’s critical illness policy) |
| VitalityLife, plan summary (VLTD182053WF_02/25, adviser literature) | Life with Serious Illness Cover, which the summary says "works differently to Critical Illness Cover" | "the amount of cover remaining for future serious illness claims will reduce by the amount we have paid", so more than one payment is possible |
How many conditions does each insurer list as standard?
Each insurer counts conditions its own way and defines them differently, so these counts, quoted where a document gives one, are not like-for-like.
| Insurer and document | Conditions stated | Extras and options |
|---|---|---|
| Aviva (AL50001 02/2026) | "32 critical illness conditions, two additional critical illness conditions and children’s benefit as standard" | An extra-cost upgrade adds 15 further critical illness conditions, plus hospital and pregnancy benefits |
| Zurich (NP720500009 02/25) | "There are 39 critical illness Full Payment conditions and 2 Additional Payment conditions." | Children’s Benefit at extra cost |
| Royal London (adviser web page, read October 2026) | "46 main definitions that pay out the full sum assured" and "32 additional conditions that pay out 50% of the sum assured, up to a maximum of £35,000" | Standard or Enhanced children’s cover, or none |
| LV= (April 2026) | Full payment conditions numbered 1 to 38 and additional payment conditions numbered 40 and 41 | Total permanent disability (condition no.39), which LV= says must be bought through a financial adviser |
| Scottish Widows Protect (January 2026) | Conditions listed by body system, plus a separate list of additional payment conditions | Total Permanent Disability, covered only if you have chosen that feature |
| Legal & General (QGI14786 2026/10) | A named list running from aorta graft surgery to traumatic brain injury | "Accident Hospitalisation Benefit and Children's Critical Illness Cover are included with our Critical Illness Cover at no extra cost." |
| Vitality (web page, captured 23 August 2026) | "114 conditions covered" at its standard level, and "up to 174 conditions" on its higher levels | Higher levels, which Vitality says can only be added through a financial adviser |
A longer list shows how many names an insurer includes, not how each is defined or how much it pays; Vitality’s, for one, pays by severity. Wording differs too. LV= lists "Stroke – of specified severity", while Legal & General’s list describes stroke as "resulting in symptoms lasting at least 24 hours"; a claim is judged against the full definition in each policy’s terms. See the ABI minimum standards and conditions covered.
Should you want these lists read against your own medical history, say so when you complete the form here; the FCA-authorised broker who calls does the checking, and you commit to nothing.
What smaller payments does each insurer make?
| Insurer | Smaller payment | Other payments described |
|---|---|---|
| Zurich (02/25) | "£25,000 or 25% of the sum assured, whichever is lower" for an additional payment condition; "Once paid, your policy will continue unchanged." | — |
| Royal London (July 2025) | The lower of 50% of the cover or £35,000 for an additional condition | Additional-condition claims "don't affect the ability to claim for a more serious illness later" (adviser page) |
| LV= (April 2026) | The lower of 25% of cover or £30,000; the policy does not end | An extra 50% on top of the amount of cover for certain accident claims, up to £200,000 |
| Scottish Widows (January 2026) | 25% of cover, "The most we’ll pay is £30,000" | A booster of 150% of cover if you are 45 or under with a named neurological illness (at most £200,000 on top), and an advance payment while on an official UK waiting list for certain heart operations, brain or spinal tumours and organ transplants; either ends the policy |
| Aviva (AL50001 02/2026) | For level and decreasing cover, "£25,000 or 25% of your cover amount, whichever is lower"; "the policy will remain in force" | The upgrade adds hospital and pregnancy benefits |
| Legal & General (QGI14786 2026/10) | 25% of cover up to £25,000; the amount of cover and premiums are not affected | Accident hospitalisation benefit, included at no extra cost |
| Vitality (02/25) | A share of cover by severity, "from 5% (Severity G)" to "100% (Severity A)"; 1X covers levels A to D, 2X A to E, 3X A to G | 1X, 2X and 3X allow up to 100%, 200% or 300% of the initial amount across several claims |
How do children’s cover terms compare?
Some include it, some charge for it, and ages and amounts differ. Child critical illness cover explains the benefit itself.
| Insurer | How it comes | Ages and amount |
|---|---|---|
| Aviva | Children’s benefit included as standard | Cover from 30 days old to age 18 (or 21 if in full time education); £25,000 or 50% of cover, whichever is lower |
| Legal & General | Included with critical illness cover at no extra cost | A child between 30 days old and the 18th birthday (21st if in full time education); the lower of 50% of cover or £25,000 |
| Scottish Widows | Included with critical illness cover | Birth to the 22nd birthday; 50% of cover up to £30,000 |
| Zurich | Children’s Benefit, an option at extra cost that can be added or removed | Until the 22nd birthday; the lower of £25,000 or 50% of the sum assured |
| LV= | An option "for an additional cost" | Birth to the 23rd birthday; the lower of 50% of cover or £35,000 |
| Royal London | Choose none, Standard or Enhanced | Standard: 50% of cover up to £30,000. Enhanced: up to £50,000 |
| Vitality | Added to an adult plan | Up to £100,000 of Child Serious Illness Cover across your children and plans |
Vitality says its child cover "does not cover any pre-existing medical conditions" that existed before the cover started, and Royal London’s Standard option leaves out additional conditions. For a policy on a child, see life insurance for children.
What critical illness claims figures do insurers publish?
Aviva, LV= and Royal London publish their own 2025 critical illness claims figures. Each counts on its own basis (Aviva’s includes children’s and disability claims), so they are context, not a league table.
- Aviva’s March 2026 release says it paid more than £388 million across 5,500 critical illness, children’s benefit and total and permanent disability claims in 2025, and "Aviva paid 90.7% of claims received in this category".
- LV=’s look back at its 2025 claims (July 2026) says that for critical illness "90% of all claims were paid", and almost £33m went to 444 individuals and families.
- Royal London’s adviser page, under "Our 2025 claims record", gives £197.8m paid in critical illness claims, £944,933 paid in claims for additional conditions, and 2,959 claims paid.
More figures, including the ABI’s industry totals, are on critical illness claims statistics, and when critical illness cover does not pay out covers declined claims.
What else should you check before comparing quotes?
Terms alone cannot name the most comprehensive provider; what matters depends on what the cover is for. Four more checks from the same documents:
- Guaranteed or reviewable premiums. Aviva, Royal London and Vitality offer either. Aviva reviews a reviewable premium every five years without looking at "things like your age or your health"; Royal London’s five-yearly review means it "could go up or down". Zurich, Legal & General, LV= and Scottish Widows describe premiums that stay the same unless you change the cover or choose increasing or inflation-linked cover. A reviewable quote and a guaranteed one are different promises.
- Survival periods. LV= and Vitality require 14 days after diagnosis, Aviva says "you survive for at least 10 days", and Royal London pays nothing if the person covered "dies within 10 days of meeting one of our critical illness definitions". See when critical illness pays out.
- The channel. Royal London’s cover is "Available through an independent financial adviser", and LV= says total permanent disability must be bought from one, so some options are not open to someone buying direct.
- Matching terms. Quotes compare only on the same sum, term, premium type and children’s option; health can change what is offered (pre-existing conditions).
Frequently asked questions
Is critical illness cover sold without life insurance?
Zurich’s key features list "Critical Illness Cover which pays your chosen cover amount if you’re diagnosed with a critical illness covered by the policy", and Scottish Widows Protect offers Critical Illness Cover beside Life with Critical Illness Cover. Other insurers’ rules are on buying critical illness cover on its own.
Is Vitality’s serious illness cover the same as critical illness cover?
No. Vitality’s summary says a payment "may be more than, the same as or less than you would receive from a policy with Critical Illness Cover". Each claim pays a share of cover set by severity. Vitality’s serious illness cover sets out its terms.
If you would like these differences priced for you, the form on this page requests a free call: an FCA-authorised broker can then line up offers on matching terms, though no broker can promise an insurer will accept you.
