TL;DR: Buying life insurance at 40 is still well within the window where premiums are competitive and underwriting is broadly accessible. The key decisions at this age involve choosing the right term length, selecting between joint and single policies, and aligning cover with remaining mortgage liabilities. Delaying beyond 40 accelerates the premium curve significantly, making a purchase decision in the early-to-mid forties one of the most cost-effective timing choices available. Full medical disclosure is required under the Consumer Insurance (Disclosure and Representations) Act 2012 regardless of the product chosen.
KEY FACTS

Why 40 Is a Pivotal Age for Life Insurance Decisions
The early forties represent a practical inflection point in the life insurance market. Premiums at 40 reflect a mortality risk profile that, while higher than at 30, remains within a range where mainstream insurers compete actively and underwriting decisions are typically straightforward for applicants in reasonable health. The premium gap between a policy purchased at 40 and one purchased at 45 or 50 is meaningful in cumulative cost terms over a 20 or 25-year term, making the timing of a purchase decision at this age financially significant. The ABI's published guidance on life insurance confirms the relationship between age and premium, and the steepening of the premium curve from the mid-to-late forties onward means that each year of delay carries an increasing cost consequence. For applicants at 40 who are in good health with no significant medical history, underwriting is likely to proceed at standard rates without the additional scrutiny or loading that becomes more common in the late forties and beyond. For those with existing health conditions, the underwriting outcome at 40 is generally more favourable than it would be at a later age when the same condition has progressed or been joined by additional diagnoses. The combination of competitive premiums and accessible underwriting makes the early forties a genuinely practical window for life insurance purchase, and the FCA's Consumer Duty framework reinforces the obligation on insurers and distributors to ensure that customers at this life stage receive products that genuinely meet their needs rather than being sold coverage that is either inadequate in amount or unnecessarily expensive.
Term Length Decisions: 25-Year vs 30-Year Cover
One of the most consequential decisions for a 40-year-old purchasing term life insurance is the length of the term. The two most common choices at this age are 25-year and 30-year terms, which would take the policy to age 65 and 70 respectively. The appropriate term depends on the specific financial obligations the policy is intended to address. For applicants with a mortgage, the term should align with or exceed the remaining mortgage period, ensuring that the policy remains in force for the full duration of the debt. For applicants whose primary concern is income replacement for dependants, the term should extend at least until the youngest dependant is likely to be financially independent, which for a 40-year-old parent of a young child may mean a 20 to 25-year term rather than a shorter one. A 30-year term from age 40 provides cover to 70, which encompasses the full working life and the period of transition into retirement, during which pension income may be building but not yet fully accessible. The premium difference between a 25-year and a 30-year term is typically modest relative to the additional coverage provided, and MoneyHelper indicates that selecting a slightly longer term than initially considered necessary is a common approach recommended by advisers to avoid the applicant finding themselves without cover in their late sixties. Decreasing term policies, where the sum assured reduces over time in line with a repayment mortgage balance, are a cost-effective option for mortgage-linked cover, and the premium is lower than for a level term policy providing the same initial sum assured.
Joint vs Single Policies: The Couple's Decision
For couples purchasing life insurance at 40, the choice between a single joint policy and two individual single policies is a structural decision with long-term implications. A joint life policy pays out on the first death of either named policyholder, after which the policy ends. A couple each holding individual single policies maintains separate coverage for each partner throughout the full term of each policy. The premium for a joint policy is typically lower than the combined premium for two individual policies providing equivalent cover, making joint policies appear cost-effective at the point of purchase. However, the joint structure means that the surviving partner is left without life insurance cover following the first death, at an age when they will be older and potentially in worse health than at the time of the original application, making new individual cover more expensive or, in some cases, less accessible. For couples with different cover needs, different health profiles, or different intended term lengths, individual policies allow each person's cover to be tailored to their specific circumstances rather than being constrained by a joint structure that may not equally serve both partners. MoneyHelper provides guidance on the trade-offs between joint and single policies and notes that the longer-term cost of replacing cover for the surviving partner is a factor that is frequently underweighted when joint policies are initially purchased. The FCA's Consumer Duty framework requires distributors to ensure that the product structure recommended genuinely meets the needs of the customer, and for couples with different financial profiles, individual policies often provide a better structural fit.
Mortgage-Linked Life Cover: Aligning Protection with Debt
The most common trigger for life insurance purchase at 40 is the existence of a mortgage, and aligning the level and term of cover with the outstanding mortgage balance is a practical and widely used approach. Mortgage-linked life insurance can be structured as a decreasing term policy, where the sum assured reduces in line with the outstanding capital balance on a repayment mortgage, or as a level term policy, where the sum assured remains constant throughout the term regardless of the declining mortgage balance. The decreasing term structure is the most cost-effective for pure mortgage protection because the cover accurately reflects the liability it is designed to address at each point in time. The level term structure provides more comprehensive protection because it maintains the full sum assured even as the mortgage balance declines, leaving additional funds that could support dependants or address other financial needs in the event of death. For applicants at 40 with 20 to 25 years remaining on a repayment mortgage, the mortgage represents the most straightforward anchor for calculating a minimum cover amount, with any additional income replacement or dependant support considerations determining whether a higher level of cover is appropriate. MoneyHelper advises that life insurance should be reviewed whenever a significant change in financial circumstances occurs, including remortgaging, and that the cover level should be recalculated at that point to ensure it remains adequate. For applicants who have recently taken a larger mortgage or extended a mortgage term, a review of existing cover against the revised liability is a practical step that the Consumer Duty framework supports through its requirement for fair value.
Pre-Existing Conditions at 40: Underwriting and Disclosure
At 40, the prevalence of pre-existing medical conditions among applicants is higher than at younger ages, and the underwriting process reflects this. Conditions such as hypertension, high cholesterol, type 2 diabetes, and mental health history are among the most commonly declared conditions by applicants in this age group. The Consumer Insurance (Disclosure and Representations) Act 2012 requires all applicants to take reasonable care not to misrepresent their medical history, and all relevant conditions, medications, and lifestyle factors asked about in the application must be disclosed accurately. Non-disclosure of a material condition that subsequently becomes relevant to a claim can result in the claim being reduced or refused, and in cases of deliberate non-disclosure, the policy may be voided. For applicants with a significant medical history, the underwriting outcome may include a premium loading, the exclusion of specific conditions from the policy, or in some cases a decline. Where a mainstream insurer declines or applies terms that the applicant considers disproportionate, the BIBA find-a-broker service and specialist life insurance providers offer alternative routes to cover. The FCA's Consumer Duty framework requires insurers to communicate underwriting decisions clearly and to ensure that the reasons for any loading or exclusion are explained, allowing the applicant to make an informed decision about whether to proceed. The Financial Ombudsman Service provides recourse for applicants who believe an underwriting decision was made on incorrect information or applied disproportionate terms, and its service is free to consumers.

Frequently Asked Questions
Is 40 too old to get life insurance?
No. Forty is well within the age range at which mainstream life insurance is widely available, competitively priced, and accessible to applicants in reasonable health. Premiums are higher than at 30 but significantly lower than at 50 or 60. The ABI confirms that life insurance remains broadly accessible throughout the forties, and that the earlier a policy is purchased within this decade, the lower the cumulative cost over the policy term.
How much life insurance do I need at 40?
MoneyHelper advises that the appropriate sum assured should reflect the outstanding mortgage balance, income replacement needs for dependants, and any other debts or financial commitments that would fall to survivors. There is no single universal formula, but common approaches include multiples of annual income, the outstanding mortgage balance, or a combination of both. Calculating the amount based on the specific financial profile of the applicant and their dependants is more reliable than applying a generic rule.
Is a joint policy or two single policies better for couples?
Each structure has distinct trade-offs. A joint policy is typically cheaper at the point of purchase but ends after the first death, leaving the surviving partner without cover. Two individual single policies maintain protection for each partner throughout their respective terms but cost more in combined premiums. For couples with different health profiles, income levels, or cover needs, individual policies provide greater flexibility and are often the more appropriate long-term structure.
Do I have to declare past mental health treatment when applying for life insurance at 40?
Yes, if the application asks about it. The Consumer Insurance (Disclosure and Representations) Act 2012 requires applicants to answer all questions accurately and completely. Mental health history, including depression, anxiety, or any related treatment or medication, must be declared if asked. The underwriting outcome varies between insurers: some accept applicants with a past mental health history at standard rates, others apply a loading, and some may exclude mental health-related conditions. The FOS has upheld complaints where insurers refused claims on the basis of minor undisclosed mental health history that was found to be immaterial to the risk.
What happens if I miss a premium payment on my life insurance policy?
Most life insurance policies include a grace period, typically 30 days, during which a missed payment can be made without the policy lapsing. If payment is not received within the grace period, the policy may lapse, meaning cover ceases. Some insurers allow reinstatement of a lapsed policy within a defined period, subject to evidence of continued insurability. Travellers should check the specific terms of their policy for the grace period and lapse provisions, and contact the insurer promptly if a payment difficulty arises.
