Why can’t an average premium figure predict what I will be quoted?

An average blends people of very different ages, health profiles, smoking statuses and cover amounts into one number, so it cannot reflect your own circumstances. Two people seeking the same sum assured can receive very different quotes once an insurer has assessed their individual risk. Treat any average premium you see online with caution unless it comes with a named source and a date, and even then use it only for general scale rather than as a prediction of your own cost. A written quote against your own specification is the only reliable figure.

Does a cheaper reviewable premium cost less over the whole term?

Not necessarily. A guaranteed premium is fixed for the whole term you choose, so it cannot rise even if your health changes or the insurer’s costs increase. A reviewable premium can be re-rated by the insurer at set intervals written into the policy, which can make an initially cheaper quote considerably more expensive later in the term. Neither basis changes whether a valid claim is paid; the choice is purely about cost certainty. Checking which basis a quote uses, in writing, is as important as comparing the starting price.

How should I compare quotes from different life insurance providers?

Fix your specification first — the exact sum assured, the term length and whether you want guaranteed or reviewable premiums — and keep it identical across every quote you request. Only then are the figures genuinely comparable, because differences at that point reflect each insurer’s underwriting of your risk rather than a different product. Request quotes in writing, note the date each one was given, and remember that a cheaper quote often means different terms somewhere in the small print that is worth reading closely.

How much does life insurance cost in the UK?

The short answer

There is no single honest figure: premiums depend on your age, health, smoking status, the sum assured, the term length and whether premiums are guaranteed or reviewable. Any “average premium” without a named source and date cannot predict your quote. Fix a specification, then compare written like-for-like quotes.

Thinking about how much life insurance costs

What works well

A fixed specification makes quotes genuinely comparable.
Guaranteed premiums remove future repricing risk.
Younger applicants lock in the lowest rates of their lives.

What to watch

Averages without sources cannot predict an individual quote.
A cheaper quote usually means different terms somewhere specific.
Reviewable premiums can rise sharply at review dates.

Why the honest answer is a method, not a number

Every circulated “average premium” hides a different mix of ages, smoking statuses and cover amounts, so it cannot predict your quote. The disciplined approach is to fix the specification first — sum assured, term, guaranteed premiums — then collect written quotes against that identical specification and compare them line by line. What the structure tells you without any figures: term assurance is the cheapest form of cover because a pay-out is possible rather than certain; whole of life costs multiples of term for the same sum because a pay-out is guaranteed; and smoking status is one of the largest single rating factors after age. No insurer publishes a comparable market-wide table of premiums by age band, so none is quoted here; the closest dated figure is Legal & General’s own published average of £26.33 a month (July 2026), which is a single insurer’s book rather than a market average.

Write down your exact specification, request quotes against it in writing, and keep each insurer’s document with its date — a quote without a date is not comparable. Whatever the specifics of how much life insurance costs, the discipline that protects your family is always the same: get the insurer’s position in writing, keep the documents with the policy, and make sure the people who would claim know the policy exists and where the paperwork lives.

What moves the price

Life insurance premiums are set at the outset from your age, your answers on health and lifestyle — smoking status is one of the largest single factors — the sum assured, the length of cover and the premium type. Guaranteed premiums stay fixed for the term; reviewable premiums can be re-priced by the insurer at set intervals, which makes a cheaper starting quote expensive later. Average premium figures circulate widely online, but an average built from different ages, health profiles and cover amounts cannot predict your quote — treat any average without a named source and a date as unusable. For scale rather than prediction, Legal & General published an average UK life insurance cost of £26.33 a month in July 2026, drawn from its own 2025 book. ^[2]

One genuine lever does exist beyond the cover design itself: the underwriting outcome. Two insurers can assess the same medical history differently, so written quotes against an identical specification — same sum assured, same term, same premium type — are the only honest comparison. Pay-out statistics matter when weighing price against reliability: ABI and GRiD data shows protection insurers paid a record £7.34 billion in 2023, equivalent to roughly £20.1 million a day. ^[1]

How to compare two quotes

Fix the cover first: the amount, the term and whether premiums are guaranteed or reviewable.
Ask for each quote in writing, with its date.
Put the quotes side by side and mark every difference in terms before you look at price.
Ask whether any exclusion or price increase was added because of your health answers.

In practice

Insurers treat you as a smoker if you have used any nicotine product in the last 12 months, and that includes vapes, patches and gum. Smoker rates are substantially higher. If you stop, many insurers will reconsider the premium once you have been nicotine-free for 12 months, but you have to ask, and they may ask for a test.
