Life insurance premiums in the UK are calculated based on the statistical likelihood of the insurer having to pay a claim during the policy term, combined with the size of the payout, the duration of cover, and a range of personal factors specific to the applicant.

Understanding what drives the cost of life insurance helps you make informed decisions about the type and amount of cover you arrange. This article sets out the main factors that insurers consider and how each one affects your premium.

Factor 1: Age

Age is the single most significant factor in life insurance pricing. The older you are when you take out a policy, the higher the statistical likelihood of dying during the policy term, and therefore the higher the premium. A healthy non-smoker in their early 30s will typically pay significantly less than an equivalent applicant in their 50s for the same level of cover over the same term.

This is also why financial advisers commonly recommend arranging life insurance earlier rather than later. Locking in premiums at a younger age, when health is generally better, can result in substantially lower costs over the life of a policy.

Factor 2: Health and Medical History

Insurers assess your current health and your medical history as part of the underwriting process. You will typically be asked to complete a medical questionnaire, and in some cases the insurer may request a report from your GP or arrange a nurse screening.

Factors that can affect your premium include existing medical conditions, a history of serious illness, regular prescription medication, mental health history, and family history of hereditary conditions such as certain cancers or heart disease.

Factor 3: Smoking Status

Smokers typically pay between 50% and 100% more than non-smokers for equivalent life insurance cover. Most UK insurers classify you as a non-smoker if you have not used tobacco or nicotine products, including e-cigarettes and vaping, for at least 12 consecutive months. Nicotine replacement therapy such as patches or gum generally counts as nicotine use.

If you have recently stopped smoking, you will initially pay smoker rates, but after 12 months smoke-free you can usually ask the insurer to reassess your status.

Factor 4: The Sum Assured

The larger the payout you want the policy to provide, the higher the premium. This relationship is broadly linear, though pricing is not always proportionate, and different insurers price large sums assured differently.

Factor 5: Policy Term

A longer policy term means more years during which the insurer is at risk of having to pay a claim. All else being equal, a 30-year policy costs more per month than a 20-year policy for the same sum assured.

Factor 6: Type of Policy

Decreasing term insurance, where the sum assured reduces over time in line with a repayment mortgage, is cheaper than level term insurance, where the payout stays fixed. Whole of life insurance, which has no end date and is guaranteed to pay out eventually, is more expensive than term policies.

Factor 7: Occupation

Certain occupations carry higher risk and result in premium loadings. Roles involving working at height, hazardous materials, or offshore environments are the most commonly affected. Most standard professional and office roles have no impact on the premium.

Factor 8: BMI

A very high or very low BMI can indicate increased health risk and may result in higher premiums or a request for additional medical information before a decision is made.

Guaranteed vs Reviewable Premiums

When comparing quotes, it is important to check whether the premiums are guaranteed or reviewable. Guaranteed premiums stay fixed for the entire policy term. Reviewable premiums can be increased by the insurer at review points, typically every five or ten years, based on their updated assessment of risk. Reviewable premiums are sometimes lower initially but carry the risk of significant increases over time.

Frequently Asked Questions

Why did my life insurance premium change between getting a quote and applying?

A quote is an indication of price based on limited information. Once you complete a full application with detailed medical and lifestyle disclosures, the insurer underwrites your risk properly. If any information disclosed in the application indicates a higher risk than the quote assumed, the final premium may be higher.

Does paying annually instead of monthly save money?

Yes, in most cases. Many insurers offer a discount of around 2% to 5% if you pay an annual premium upfront rather than monthly. Over a 25-year policy term, this can represent a meaningful saving.

Does my credit score affect my life insurance premium?

No. Life insurance underwriting is based on health and lifestyle risk, not financial creditworthiness. Your credit score is not a factor in the premium calculation.

Why are premiums different between insurers for the same cover?

Different insurers have different views of risk, different reinsurance arrangements, and different target customer profiles. One insurer may price certain health conditions or occupations more favourably than another. This is why comparing across the whole market, particularly through a broker, typically produces better outcomes than going directly to a single insurer.
