- -Adding CI roughly doubles the premium compared to life-only cover
- -Average CI claim: £67,600 (ABI 2024) — enough for a significant mortgage contribution

- -1 in 2 people will develop cancer in their lifetime (Macmillan)
Why Consider CI Cover for Your Mortgage?
Your mortgage is likely your largest financial commitment. Life insurance pays off the mortgage if you die — but what if you survive a serious illness and cannot work? Critical illness cover for a mortgage provides a lump sum to help with repayments when your income is reduced or stopped.
According to Macmillan Cancer Support, 1 in 2 people will develop cancer in their lifetime. The ABI reports that CI claims reached \u00a31.3 billion in 2024 with an average payout of \u00a367,600 — enough to cover a significant portion of most UK mortgages.
The FCA (December 2025) found only 42% of UK consumers have any protection policy, leaving millions of mortgage holders exposed.

CI for Mortgage: Level or Decreasing Term?
How you structure CI cover for your mortgage depends on your mortgage type:
Decreasing Term CI (Repayment Mortgage)
The CI payout reduces over time, matching your repayment mortgage balance. Cheapest option. If diagnosed, the payout covers the remaining mortgage.
Level Term CI (Interest-Only or Flexibility)
The CI payout stays the same throughout the term. More expensive but gives a fixed lump sum. Better if you have an interest-only mortgage or want flexibility.
Combined Life + CI for Mortgage
One policy covering death and critical illness. Pays out on whichever happens first. The most common approach for mortgage protection.
Do You Need Both Life and CI?
Life cover alone is cheaper but only pays on death. Adding CI roughly doubles the premium but covers the far more likely scenario of surviving a serious illness.

Critical Illness Cover For Mortgage FAQs
Do I need critical illness cover for my mortgage?
Your lender does not require it, but it protects your biggest financial commitment. If you develop a serious illness and cannot work, CI cover provides a lump sum to help with mortgage repayments. With 1 in 2 people developing cancer, the risk is real.
How much does CI cover for a mortgage cost?
Adding CI to a mortgage life insurance policy roughly doubles the premium. For a healthy 30-year-old non-smoker with £250,000 cover over 25 years: life-only might cost £10-15/month; life + CI might cost £25-35/month.
Should I get decreasing or level CI for my mortgage?
Decreasing CI matches a repayment mortgage (cheaper). Level CI gives a fixed payout regardless of remaining balance (more expensive but more flexible). For most repayment mortgages, decreasing is the standard choice.
Can I add CI cover to my existing mortgage life insurance?
Usually not to an existing policy. You would need to take out a new combined life and CI policy. Alternatively, take out a separate standalone CI policy alongside your existing life cover.
