There is no single best life insurance policy in the UK: the best one for a household is the type that matches what it needs to protect, on terms that hold up when a claim is made, from an insurer whose record you can check. This guide compares the main policy types, the features that separate a good policy from a weaker one, and how to judge the companies selling them.
We do not rank insurers or name a winner. If you would like to see how several insurers would treat your own age, health and budget, fill in the quote form on this page and an FCA-authorised broker can talk it through with you. It costs nothing, and you are under no obligation to buy.
Which type of life insurance is best?
The type of cover matters more than the brand. A term policy pays out only if you die (or, on many policies, are diagnosed with a terminal illness) before an end date you choose. Whole of life cover has no end date. Within those two, the main choices are:
| Policy type | What the payout does | Often chosen for |
|---|---|---|
| Level term | Stays the same for the whole term | A fixed lump sum for family, or debts that do not reduce |
| Decreasing term | Falls each month, roughly in step with a repayment loan | A capital and interest mortgage |
| Increasing term | Rises each year to help keep pace with the cost of living, usually with rising premiums | Long terms where inflation would erode a fixed sum |
| Joint policy | Usually pays once, on the first of two people to claim | Couples with shared debts |
| Whole of life | Pays whenever you die, as long as premiums are paid | Leaving a sum regardless of when death happens |
| Over-50s plan | A fixed sum, with no medical underwriting but a reduced payout early on | Older buyers who want acceptance without underwriting |
The table rests on insurers' own wording. Aviva's Life Insurance+ policy summary says decreasing cover "can be a good option to cover the reducing amount you might owe on a capital and interest repayment mortgage or other loans", and that for joint policies it pays out when the first of the two people covered makes a claim.
For whole of life cover, Macmillan Cancer Support's guide to insurance types (reviewed September 2023) explains that it "pays out the lump sum when you die, whenever that happens", and notes that some premiums "get reviewed after a set time, usually 10 years". The same guide says an over-50s plan accepts you without medical underwriting, but if you die of natural causes soon after buying it, "it will not pay out in full. This is usually the first 1 to 2 years." It adds that if you live a long time, "you may pay in more money than is paid out when you die".
MoneySavingExpert, in its life insurance guide updated 2 October 2026, takes the view that "For most, level-term life insurance is the cheapest and simplest option." That is its general view, not a ranking of providers. Our guide to the types of life insurance goes deeper, and couples weighing one policy against two can read how joint life cover compares.
Is life insurance worth paying for?
It depends on whether anyone relies on your income. MoneySavingExpert puts the test simply: "If someone depends on your income, life insurance can help protect them financially if you die." Parents of young children and couples who need two incomes for a mortgage are where cover usually earns its cost.
It is harder to justify when nobody relies on your income and your debts would be cleared from your estate. A term policy is not a savings plan either. Legal & General's Life Insurance policy summary (QGI14768, dated 2026/10, the version sold through Barclays) says plainly that its policies have no cash value, and that nothing is paid if you reach the policy's end without having made a valid claim.
Before buying, check what you already have. Macmillan's guide suggests asking your mortgage provider whether life cover is already included, and notes that "Many employers offer a type of life insurance called death-in-service benefit." It can end when a job or mortgage changes, but it affects how much new cover you look for. Our page on whether you need life insurance goes further.
What makes one life insurance policy better than another?
Two policies with the same sum assured and term can still differ in ways that matter. Compare these in each policy summary before the price.
Guaranteed or reviewable premiums
With guaranteed premiums the price is fixed for the life of the policy unless you change it. Reviewable premiums can move. Aviva's Life Insurance+ summary says that on reviewable premiums it reviews the premium every five years to check you are paying the right price for the cover you chose, and may decide it should go up, go down or stay the same. The same document says life-only cover there comes with guaranteed premiums, while reviewable premiums are an option on life and critical illness cover. More in why life insurance premiums can rise.
How terminal illness cover is defined
Both policies pay early on a terminal diagnosis, but the test differs. Legal & General's summary says you are covered if your hospital consultant and its Medical Officer expect the illness to lead to death within 12 months, and that terminal illness cover cannot be claimed if the length of the policy is less than two years. Aviva pays if "an attending consultant doesn't expect you to live longer than another 12 months". Both are the insurers' own definitions; read the full policy conditions rather than assuming any policy will pay. More in our guide to terminal illness benefit.
Age limits and term lengths
These set who can buy and for how long. Legal & General's summary for the policy it provides through Barclays sets a minimum age of 18, a maximum age of 74 to buy, a term of 5 years to 50 years, and says the policy must end before age 90; limits differ by insurer and by how a policy is sold. Aviva's term "can be between one and 50 years".
Extras included at no cost
If Aviva needs more information before it can give a decision, its Protection Promise covers customers under 55 free of charge, and its summary lists house purchase cover as included on level or decreasing cover. Such extras differ between insurers, each with its own conditions.
Writing the policy in trust
Legal & General's summary says that if a policy is written under a suitable trust, the death payout should not form part of the estate for Inheritance Tax purposes. MoneySavingExpert's guide says "Consider writing your policy in trust." Whether one suits you is for you and a professional; our guide to life insurance trusts explains the options. That is a description of the general position, not tax advice, and the rules can change.
Gift cards and cashback
Post Office, for example, offers "a £100 gift card or experience worth up to £200" on its life insurance page. An incentive has its own terms and does not change what the cover does, so weigh it only after the cover itself.
An FCA-authorised broker can compare these features across several insurers in one conversation, including how each is likely to treat your health; the form on this page is the way to ask.
How to judge life insurance companies on claims, complaints and reviews
Lists of best-rated insurers rarely say what they measured. Four checks rest on published records.
- Claims paid. Across the industry, the Association of British Insurers reported that 97.9% of individual protection claims (life, income protection and critical illness together) were paid in 2025. Some insurers publish their own figures: Aviva's March 2026 release says its life claims, including over-50s plans and terminal illness payments, had an acceptance rate of 98.7% in 2025, and Post Office says the insurer behind its Post Office Life Insurance, Scottish Friendly, "paid 98.47% of life insurance claims they received in 2025". Each is the insurer's own count on its own basis, so they are signs of a record, not a league table. Our life insurance claims statistics page goes further.
- Why claims are declined. Aviva says the leading cause of its declined life claims remained misrepresentation of relevant information, in particular about health and lifestyle. Answering the application questions fully matters more than which brand you choose.
- Complaints. The Financial Ombudsman Service publishes complaint numbers and uphold rates for named businesses. Its latest release, dated 22 July 2026, covers 1 July 2025 to 31 March 2026 and includes only firms where it "received and resolved at least 45 complaints", so a small insurer's absence tells you little.
- Authorisation. The FCA describes its Financial Services Register as a public record of the firms, individuals and other bodies that are, or have been, authorised by the FCA or the PRA. Any insurer or broker you deal with should be on it.
Reviews on sites such as Trustpilot show how a firm handles service, but scores move constantly. Martin Lewis's MoneySavingExpert guide steers readers to a broker: execution-only if you know what cover you want, advisory if you are unsure or have a medical condition. We cite it for what it says, not as an endorsement.
Which life insurance company is cheapest?
No insurer is cheapest for everyone. Each insurer prices on your own details: age, health, smoking, amount of cover, term and policy type. The order of insurers can change from one applicant to the next. Our page on what life insurance costs explains what moves the price, and the cost and quotes guides cover the rest.
An actual figure comes from a quote on your own details, from an insurer directly or through a broker. To have an FCA-authorised broker compare several insurers for you, use the form on this page; our guide to getting quotes covers the other routes and what you will be asked.
Being a woman no longer changes the price on its own. The explanatory memorandum to the Equality Act 2010 (Amendment) Regulations 2012 records that "from 21 December 2012, the use of sex as a risk factor should not result in differences in individuals' insurance premiums and benefits". Health, smoking and other answers still count for everyone.
Which life insurance suits different ages and households?
Age changes which products are open to you more than which one is best. In your twenties and thirties, many people match a long term to a mortgage or to when children will be independent. Couples in their forties often weigh one joint policy against two single ones. From the fifties onward, maximum buying ages and end ages start to bite: on the Legal & General policy sold through Barclays, the limit is 74 to buy, with cover ending before 90. Later on, some people look at whole of life cover or the plans compared in our guide to over-50s cover.
Cover for a child is a different question, covered in life insurance for children. Insuring a parent needs what Legal & General calls an insurable interest, and the parent's consent. If a parent is already seriously ill, ask the insurer or a broker what could be offered; our page on life insurance for parents explains what may still be possible. Marie Curie's Support Line, 0800 090 2309, offers free information and emotional support to people living with a terminal illness and their families.
Frequently asked questions
What are the top 10 life insurance companies in the UK?
We do not publish one: the insurer that suits one application can be dearer or narrower on the next. Claims records, complaint data and policy terms, set out above, are fairer tests.
What happened to AIG life insurance in the UK?
Aviva says it has completed the acquisition of AIG Life Limited from Corebridge Financial; former AIG Life policies now sit with Aviva Life & Pensions UK Limited (AIG life insurance, now Aviva). Existing policyholders should use the contact details in their own policy documents.
Who provides HSBC life insurance?
HSBC UK's life insurance page refers customers to "one of our insurance providers" and says Premier customers can see an adviser who recommends a policy "from our hand-picked list of providers". Ask HSBC which insurer would provide your policy (HSBC life insurance).
Who provides Post Office life insurance?
Two insurers: Scottish Friendly underwrites the term plan, for ages 18 to 70 at the start, and Aviva the Over 50s Life Cover (Post Office life insurance).
Who provides Guardian life cover?
Guardian's website says Guardian Financial Services Limited is an appointed representative of Scottish Friendly, and that "All products are provided by Scottish Friendly". It sells life cover, critical illness cover, income protection and children's critical illness cover.
Which companies sell life insurance in the UK, including level term?
Of the firms mentioned on this page, Aviva, Legal & General and Post Office sell level cover; Scottish Friendly provides Post Office's and Guardian's policies; HSBC sells other providers' policies. Many more exist: check any firm on the FCA's Financial Services Register before buying.
