Legal & General vs Vitality for critical illness cover: two of the UK's major protection insurers, both FCA-authorised and both with strong track records. Here's how they compare on price, claims, features and underwriting, based on 2024 published data and our adviser panel's real application experience.
Legal & General vs Vitality — at a glance
| Insurer | Min / Max age | Max cover | Max term | Claim-paid % | Premium from |
|---|---|---|---|---|---|
| Legal & General | 18 / 77 | £1 million (£3m via IFA panel) | 50 years | 92.2% | £5/month from age 25 |
| Vitality | 18 / 74 | £5 million | 50 years | 98.0% | £6/month from age 25 (may fall with activity rewards) |
Claim-paid % figures are each insurer's latest published 2024 UK term protection figures for critical illness cover. Headline premium is indicative for a healthy non-smoker aged 25–30 at the lowest cover tier. Max cover figures reflect headline caps; both insurers may go higher case-by-case via their IFA panels.
Price: who's cheaper for critical illness cover?
For a healthy non-smoker aged 30 buying £250,000 of critical illness cover, our adviser panel sees the following pricing pattern in 2026:
- Legal & General: £5/month from age 25 — low tier pricing. competitive for healthy non-smokers; less flexible on severe pre-existing conditions
- Vitality: £6/month from age 25 (may fall with activity rewards) — mid-high tier pricing. willing on lifestyle-related risk (BMI, smoker incentives) if you commit to Vitality Programme
On pure price, Legal & General typically wins for straightforward applicants. But neither is the cheapest in the market for every profile — for diabetics, smokers, high-BMI or pre-existing mental health cases, the ranking can flip dramatically. That's the point of whole-of-market comparison rather than direct-to-insurer buying.
Claims performance
Claims-paid percentage is the single most important number in protection insurance. It's the regulated, audited statistic for how often each insurer pays when a claim is submitted.
- Legal & General: 92.2% of critical illness cover claims paid in 2024 (Legal & General Assurance Society).
- Vitality: 98.0% of critical illness cover claims paid in 2024 (Vitality Life Ltd).
On 2024 figures, Vitality has the edge. That said, both exceed the UK industry average of ~98% for term life, ~91% for critical illness, and ~90% for income protection, so the realistic difference for you as an applicant is small. What matters more is giving a complete, accurate medical history at application — non-disclosure is the overwhelming reason claims are declined across the whole market.
Features & extras compared
Legal & General
Free trust-writing, terminal illness cover included, children's cover included at no extra cost on life + cic, rehabilitation support on ip.
Vitality
Optimiser (dynamic premiums linked to activity), serious illness cover with 177 conditions and severity-based payouts, partial and full severity claims.
Verdict on features
For most applicants, the features matter as much as price. Legal & General's standout is its market-leading price for healthy applicants — consistently cheapest for straightforward level and decreasing term. Vitality's standout is its Vitality Programme — up to 40% cashback via wearable-linked activity tracking, Apple Watch rewards, Waitrose discounts. Work out which of those you'll actually use — wearable integration with Vitality is worthless if you won't wear the tracker; Aviva's Digicare+ is worthless if you're already paying for private health support; Royal London's Helping Hand mutual benefits are only compelling if you value a mutual structure.
Underwriting: who'll accept you at a better rate?
Underwriting is where the headline price comparison breaks down. Every insurer has its own strengths and weaknesses on medical history and occupation:
- Legal & General: competitive for healthy non-smokers; less flexible on severe pre-existing conditions.
- Vitality: willing on lifestyle-related risk (BMI, smoker incentives) if you commit to Vitality Programme.
If you have any health history — diabetes, cancer history, high blood pressure, BMI above 30, regular alcohol consumption, mental health treatment — the right insurer can halve your premium versus the wrong one. An FCA-authorised adviser does a pre-underwriting enquiry on both before submitting a full application, so you see the realistic price from both insurers rather than guessing.
Max cover and max term
Legal & General will write critical illness cover up to £1 million (£3m via IFA panel) over 50 years, with entry between age 18 and 77. Vitality will go to £5 million over 50 years, with entry between age 18 and 74. For most UK households, both caps are well beyond what you'd realistically need — unless you're covering a £1m+ mortgage or a £2m+ IHT-triggering estate, both are more than sufficient.
Who should pick Legal & General?
- You value market-leading price for healthy applicants — consistently cheapest for straightforward level and decreasing term.
- You fall into the profile where Legal & General's underwriting is competitive: competitive for healthy non-smokers.
- You want to use free trust-writing.

Who should pick Vitality?

Frequently Asked Questions
For a healthy non-smoker, Legal & General and Legal & General is usually cheaper at the headline level. But the real answer depends on your health and occupation — any pre-existing condition or non-standard job can flip the ranking. The only reliable way to know is to get both quoted on exactly the same cover.
Legal & General paid 92.2% of critical illness cover claims in 2024; Vitality paid 98.0%. Both comfortably exceed the UK industry average. The delta between them is small and most declined claims across the whole market come from non-disclosure at application rather than from insurer-specific strictness.
Yes. There's no limit on the number of UK critical illness cover policies you can hold, provided each policy's sum assured is reasonable relative to your financial circumstances. Splitting cover across two insurers can make sense for very high sums assured or for diversifying claims risk, though it usually costs more than consolidating with one.
Legal & General's headline difference is market-leading price for healthy applicants — consistently cheapest for straightforward level and decreasing term. Vitality's headline difference is Vitality Programme — up to 40% cashback via wearable-linked activity tracking, Apple Watch rewards, Waitrose discounts. Price and claim-paid figures are close; the decision usually comes down to which set of non-price features matches how you'll actually use the policy.
Yes, but with a catch. You can cancel any UK protection policy at any time. The catch is that your health may have changed since the original application — if you've had any medical events, the new insurer will price them into the new premium. If your health is identical, switching is straightforward; if it's materially worse, you might be better off keeping the original policy.
Always compare. Both Legal & General and Vitality sell direct, but the quotes you get direct are the same as (or slightly worse than) those available via an FCA-authorised adviser — and you only see one insurer's price. A whole-of-market comparison shows both side by side alongside every other major UK insurer, with no cost to you.
