TL;DR: Life insurance is not a legal requirement for obtaining a mortgage in the UK. Most lenders do not make life insurance a condition of mortgage approval, though some may require it in specific circumstances such as high loan-to-value lending or self-build mortgages. Decreasing term insurance matches the reducing mortgage balance; level term insurance provides broader family protection. The two are different products serving different purposes.

The legal position: life insurance is not required for a mortgage
No UK law makes life insurance a condition of obtaining a residential mortgage. A lender's ability to require insurance as a condition of lending is governed by the FCA's Mortgage Conduct of Business sourcebook (MCOB). Under MCOB 12, lenders are expressly prohibited from requiring borrowers to purchase mortgage payment protection insurance or life insurance from a specific provider or through the lender's own distribution channel - this prohibition on tying prevents lenders from using their position as a condition of mortgage approval to direct borrowers toward their own ancillary insurance products. While a lender may recommend or offer life insurance alongside a mortgage, declining to purchase the lender's own insurance product cannot lawfully be used as a reason to decline the mortgage application. Some lenders, particularly for high loan-to-value mortgages above 85% or 90% LTV, for self-build mortgages, or for borrowers in specific risk categories, may make some form of life cover a condition of lending as part of their individual credit policy. This is a commercial requirement determined by the lender's own underwriting criteria and is not universal. Borrowers should check the specific mortgage offer conditions rather than assuming either that life insurance is or is not required.
Decreasing term insurance: matching the mortgage balance
Decreasing term life insurance is the product most commonly associated with mortgage protection. It is structured so that the sum assured reduces over the policy term broadly in line with the outstanding balance of a repayment mortgage. In the early years of a repayment mortgage, the outstanding balance is close to the original loan amount - the policy sum assured matches this. As mortgage repayments are made, the outstanding balance falls; the policy sum assured falls in parallel. At the end of the mortgage term, both the mortgage balance and the policy sum assured reach zero simultaneously. The practical effect is that if the life assured dies at any point during the mortgage term, the policy payout is sufficient to clear the outstanding mortgage balance at that point. Decreasing term insurance is typically less expensive than a level term policy of equivalent initial sum assured because the insurer's financial exposure reduces over time as the sum assured decreases. The lower cost reflects the lower average payout risk. For a straightforward repayment mortgage and no other cover requirement, a decreasing term policy sized to the mortgage is a cost-efficient mechanism for protecting the property asset for the surviving family.
Level term insurance: broader protection than the mortgage alone
A level term life insurance policy maintains a fixed sum assured throughout the term regardless of how long the policy has been in force. For mortgage protection purposes, a level term policy overshoots the mortgage balance from the first repayment onward - as the mortgage balance falls, the policy continues to provide cover above and beyond what is needed to clear the debt. This excess is not waste: the additional cover beyond the mortgage balance provides income replacement, funds for dependants, or a financial reserve for the surviving family. The practical argument for level term over decreasing term for mortgage protection is that a family's financial needs do not decrease in line with the mortgage balance. A household with young children that loses a primary earner needs income replacement and childcare funding as well as mortgage clearance - the level term policy provides all of this in a single payout, whereas a decreasing term policy provides only the mortgage balance at the point of death. The cost premium for level term over decreasing term reflects the higher average payout risk and varies by age, health, term length, and sum assured. For younger borrowers with dependants and significant income replacement needs, the additional cost of level term cover may represent better value than a narrowly scoped decreasing term policy.
Interest-only mortgages and the decreasing term mismatch
For borrowers on interest-only mortgages, decreasing term insurance is structurally inappropriate as the sole mortgage protection mechanism. An interest-only mortgage does not reduce in outstanding balance during the mortgage term - only interest is paid each month and the full capital sum remains outstanding throughout. At the end of the mortgage term, the entire original loan amount must be repaid. If the life assured dies at any point during a 25-year interest-only mortgage term, the outstanding balance is the same as it was at the outset. A decreasing term policy that has reduced its sum assured to a fraction of the original loan amount would not clear this liability. An interest-only mortgage requires either a level term policy maintaining the full loan amount throughout the term, or a separate repayment vehicle such as an endowment or investment policy that will generate the capital sum at term end. The FCA's MCOB guidance requires lenders offering interest-only mortgages to have a credible repayment strategy in place - the insurance dimension of this strategy must be aligned with the interest-only structure (fca.org.uk/mcob).
Joint life versus single life policies for couples
Couples purchasing a property jointly face a choice between a joint life first death policy and two separate single life policies. A joint life first death policy covers two lives under a single policy and pays out on the death of whichever life assured dies first, at which point the policy ceases. The surviving partner is left uninsured unless a new policy is purchased. A new policy purchased after the death of a partner may be significantly more expensive if the survivor's health has deteriorated since the original joint policy was taken out, or may not be available at standard rates at all. Two separate single life policies covering the same two individuals each pay out on the death of their respective life assured - the surviving partner retains their own policy in force after the first death. The aggregate premium for two separate policies is typically higher than for a single joint policy at the same initial sum assured, but the retained cover after first death represents a significant structural advantage. The ABI notes that the lower initial cost of a joint life first death policy is offset by the loss of the surviving partner's cover on first death - a factor particularly relevant where the surviving partner would struggle to obtain affordable cover later in life.
Mortgage bundling: lender-sold insurance considerations
Many mortgage lenders and brokers offer life insurance alongside the mortgage, either as a cross-sell from the lender's own insurance arm or through a panel of insurers. The FCA's MCOB rules prohibit tying - a lender cannot require the borrower to purchase insurance through their channel as a condition of the mortgage. However, the proximity of the mortgage sale process to an insurance recommendation creates a context in which borrowers may not compare the lender's insurance offering against the open market. The FCA's Consumer Duty guidance (PS22/9) requires that any insurance product recommended in the context of a mortgage sale delivers genuine value for the specific consumer and is not recommended on the basis of commission or commercial relationship alone. Borrowers are not obliged to accept the insurance product offered at the point of mortgage completion and are free to purchase equivalent cover from any FCA-regulated insurer. Comparing the lender's offered policy against independent alternatives on the open market is within the consumer's rights and may result in materially different premium terms for equivalent cover (fca.org.uk).

Frequently Asked Questions
Is life insurance legally required when getting a mortgage in the UK?
No. There is no UK law requiring life insurance as a condition of obtaining a mortgage. Most mainstream lenders do not make life insurance a mandatory condition of mortgage approval. Some lenders may include it as a specific condition for high-LTV or self-build products - check the individual mortgage offer conditions.
Can a lender require me to buy life insurance from them?
No. The FCA's Mortgage Conduct of Business rules (MCOB 12) prohibit lenders from requiring borrowers to purchase insurance from a specific provider as a condition of mortgage approval. This is known as tying and is prohibited. A borrower can purchase life insurance from any FCA-regulated provider independent of the lender's own offering.
What is the difference between decreasing term and level term mortgage insurance?
Decreasing term insurance reduces its sum assured over the policy term in line with a repayment mortgage balance and pays only the outstanding balance at the point of death. Level term insurance maintains a fixed sum assured throughout the term, providing the mortgage clearance amount plus additional funds for income replacement or dependants. Level term is broader but more expensive.
Is a joint life policy or two separate policies better for couples with a mortgage?
A joint life first death policy is typically cheaper initially but ceases on first death, leaving the surviving partner uninsured. Two separate single life policies cost more in aggregate but each continues in force after the first death. The structural advantage of retained cover after first death is a significant factor, particularly where the survivor may face higher premiums or health restrictions on a new policy later.
Does decreasing term insurance work for an interest-only mortgage?
No. Decreasing term insurance is designed for repayment mortgages where the balance reduces over time. An interest-only mortgage balance does not reduce - the full capital remains outstanding throughout the term. An interest-only borrower requires level term insurance or a separate capital repayment vehicle to match the liability structure.
