Mortgage Protection Insurance UK 2026: MPPI, Decreasing Term Life and Critical Illness Explained

What Is Mortgage Protection Insurance?

Mortgage protection insurance (MPI or MPPI) is a broad term for any policy designed to ensure your mortgage is paid if you cannot pay it yourself. It covers three very different risks:

• Death — covered by life assurance (term life)
• Serious illness or disability — covered by critical illness cover or income protection
• Job loss or inability to work — covered by MPPI (accident, sickness and redundancy cover)

UK mortgage lenders cannot legally require you to buy protection from them as a condition of granting the mortgage (this is known as "tying" and is prohibited by the FCA). However, they must make an "appropriate explanation" of protection products and will often recommend or refer you to their tied intermediary.

All mortgage protection products sold in the UK must be provided by FCA-regulated insurers or via FCA-regulated intermediaries. If you buy from an unregulated source, you have no access to the Financial Ombudsman Service or the Financial Services Compensation Scheme.

MPPI: Accident, Sickness and Redundancy

Mortgage Payment Protection Insurance (MPPI) covers your mortgage repayments for a defined period if you are unable to work due to accident, sickness or — for employed people — involuntary redundancy. It is a form of payment protection insurance (PPI) specific to mortgage payments.

Key features of MPPI:

• Benefit period: typically 12 or 24 months maximum — not long-term
• Deferred period: usually 30–60 days before payments start (shorter = higher premium)
• Cover amount: your monthly mortgage payment, often capped at 125% of payment (to include costs)
• Redundancy cover: usually only for employees; self-employed are excluded from this element
• Waiting period: often 3–6 months before redundancy cover activates (protects against immediate claims)

MPPI was historically mis-sold alongside mortgages and loans (the PPI scandal), which led to billions in compensation and much tighter FCA regulation. Modern MPPI policies sold by reputable providers are transparent about exclusions. Always read the policy wording, not just the summary, before buying.

Decreasing Term Life Assurance

Decreasing term life assurance is the most popular and cost-effective type of mortgage life cover for repayment mortgages. The sum assured starts at a level matching your initial mortgage balance and decreases each year in line with the theoretical remaining balance (assuming a standard interest rate, set at inception of the policy).

Example: a £200,000 repayment mortgage over 25 years. A decreasing term policy would start at £200,000 cover and reduce to near £0 by year 25. If you die in year 10, the remaining mortgage balance might be around £145,000 — and the decreasing term payout would cover this.

Level Term Life Assurance

Level term life assurance pays the same fixed sum if you die at any point during the policy term — the payout does not decrease. This makes it suitable for interest-only mortgages (where the capital balance never reduces) or when you want to leave additional funds for dependants beyond just paying off the mortgage.

Level term is typically 30–50% more expensive than decreasing term for the same initial sum and term, because the insurer's liability does not fall over time. However, it provides a larger payout in later years of the term — potentially clearing the mortgage and leaving a meaningful inheritance or emergency fund for your family.

For families with young children, level term may be more appropriate than decreasing term — even after the mortgage is repaid, the death benefit can cover childcare costs, school fees, living expenses and other financial needs during the most vulnerable years.

Critical Illness Cover

Critical illness cover (CIC) pays a tax-free lump sum on diagnosis of a specified serious medical condition. Most policies cover 50+ conditions, but the most common claims are:

• Cancer (most types, excluding very early stage)
• Heart attack (of specified severity)
• Stroke (with permanent symptoms)
• Multiple sclerosis
• Coronary artery bypass surgery
• Kidney failure requiring dialysis
• Major organ transplant

CIC is typically sold as an add-on to life assurance — "life and critical illness" — so the policy pays out either on death or on a qualifying illness diagnosis, whichever comes first. Once a CI claim is paid, the life element ceases.

Critical illness cover is considerably more expensive than pure life cover — for a 35-year-old taking out a 25-year policy, adding CIC roughly doubles the monthly premium. This reflects the much higher probability of claiming during the term (you are far more likely to be diagnosed with a critical illness than to die before age 60).

Income Protection vs MPPI

Income protection (IP) insurance and MPPI both help when you cannot work due to illness or injury — but they differ significantly:

For most homeowners, income protection is the superior product — it covers all living expenses (not just the mortgage), pays indefinitely until you recover, and is available to self-employed people. MPPI is a cheaper, simpler product suitable for those who want minimal cover against a short-term income disruption.

Common Exclusions

Understanding exclusions is as important as understanding what a policy covers. The most common exclusions across mortgage protection products:

Writing Life Insurance in Trust

Writing your life insurance policy in trust is one of the simplest and most valuable financial planning steps available to UK homeowners. When a life policy is held in trust:

• The payout goes directly to your named beneficiaries, bypassing your estate
• No probate is required — payment can be made within days or weeks of your death
• The payout does not form part of your estate for IHT purposes, potentially saving 40% tax

Setting up a trust with most insurers costs nothing — it is a short form signed at the time you take out the policy. You name the trust beneficiaries (e.g. spouse and children), and the insurer holds the policy within the trust structure. For married couples, most simple discretionary trusts are sufficient.

If you already have a life policy not held in trust, it is not too late — many insurers will accept a declaration of trust retrospectively. The one limitation: once a policy is in trust, it is generally irrevocable without beneficiary consent. Get regulated advice if you are unsure which type of trust is most appropriate for your circumstances.

Joint vs Separate Policies

Couples buying together typically have the choice between a joint policy (one policy insuring both lives) or two separate policies. The right choice depends on your priorities:

• Joint policy: cheaper (typically 20–30% less than two separate policies combined); pays once — on first death only; the surviving partner then has no life cover; can be problematic if the couple separates
• Two separate policies: each pays independently; if both die (e.g. in an accident), both policies pay; cheaper total payout for the family; easier to manage if you separate or divorce

For couples with children, two separate policies are usually recommended. After the first death and mortgage repayment, the surviving parent — who now has sole responsibility for the children — still has life cover in place. With a joint policy, they would need to take out a new policy at an older age (and potentially higher cost, or with health conditions that did not exist when the joint policy was first taken out).
