Critical illness cover for contractors: lump-sum protection when you need it most
What It Does
Income protection replaces your monthly income when you can't work. Critical illness cover does something different: it pays a one-off, tax-free lump sum when you're diagnosed with a serious condition — cancer, heart attack, stroke, and others depending on the policy. The two products are complementary, not interchangeable.
What critical illness cover pays for
It pays a lump sum. What you do with that lump sum is up to you. Common uses include:
Particularly relevant for contractors with day rate-based contractor mortgages — removing the monthly payment obligation during treatment and recovery.
Private medical treatment or adaptations to your home during recovery.
Personal loans, car finance — so you can focus on recovery without financial pressure.
During treatment and recovery (income protection does this better for longer absences).
The lump sum is paid tax-free. A typical policy for a contractor might provide £150,000–£300,000 cover, roughly aligned to outstanding mortgage debt.
What conditions are covered
Critical illness policies list covered conditions. The core conditions covered by most policies:
- Cancer (most types — exclusions vary)
- Heart attack
- Stroke
- Multiple sclerosis
- Major organ transplant
- Permanent total disability
- And others — many policies cover 30–50+ conditions
The definitions matter. "Heart attack" under one policy may require different clinical evidence than another. When comparing policies, check the definitions, not just the list length.
Not covered: illness or injury that doesn't meet the specific definitions, mental health conditions (usually excluded), anything not on the specified list. This is the fundamental limitation versus income protection — IP pays when you can't work; CIC only pays on a defined diagnosis.
How critical illness is different for contractors
Unlike income protection, critical illness cover is not calculated on income — it's a fixed sum assured. This means the standard vs specialist policy distinction matters less. A contractor can buy the same CIC product as an employed person, for the same sum assured.
The contractor-specific angles are alignment with financial exposure:
Contractor mortgage outstanding: CIC should ideally cover this
No death-in-service benefit from an employer: A relevant life policy addresses death; CIC addresses serious illness
No occupational sick pay: A serious diagnosis without income protection means the lump sum has to cover more ground
Decreasing vs level cover
Two structures:
Level cover
Sum assured stays the same throughout the policy term. Better for non-mortgage protection needs.
Decreasing cover
Sum assured reduces over time, typically in line with a repayment mortgage balance. Cheaper, but only suitable if the primary purpose is mortgage protection.
Most contractors are better served by level cover or a combination — decreasing cover for the mortgage element, level cover for a personal buffer.
Critical illness via a limited company
Unlike relevant life policies, critical illness cover cannot generally be set up as a company benefit in a tax-efficient way. It is a personal protection product, paid from post-tax personal income, with the lump sum received tax-free. Noting this avoids confusion when contractors ask whether they can run it through the business.
Do contractors need both IP and critical illness?
Honest answer: they serve different purposes and most contractors benefit from both.
Income protection is the income floor — it keeps money coming in while you can't work. Critical illness is the lump-sum buffer — it clears the mortgage or major debt so that income floor doesn't have to stretch as far.
IP but no CIC
Income during illness, but the mortgage continues.
CIC but no IP
Mortgage cleared on diagnosis, but no ongoing income replacement.
Both together
The closest a contractor gets to the protection package a senior employee in a large organisation takes for granted.
FAQ: Critical Illness Cover for Contractors
What is critical illness cover?
Critical illness cover pays a tax-free lump sum if you are diagnosed with a specified serious condition — typically including cancer, heart attack, and stroke among others. Unlike income protection, it pays once on diagnosis rather than as an ongoing monthly benefit.
Is critical illness cover different for contractors?
The product itself is the same, but the context is different. Contractors have no employer sick pay, no death-in-service benefit, and no occupational protection of any kind. Critical illness cover fills part of that gap — particularly for mortgage protection — alongside income protection insurance.
Can I put critical illness cover through my limited company?
Generally no. Critical illness cover is a personal protection product and cannot be set up as a company benefit in a tax-efficient way, unlike relevant life policies for life cover. Premiums are paid from post-tax personal income; the lump sum is received tax-free.
How much critical illness cover do contractors need?
A common starting point is to align cover with outstanding mortgage debt, so that a serious diagnosis clears the mortgage and removes that financial pressure. Contractors without a mortgage or with other significant debts may choose a different sum assured. A financial adviser can model the right level for your circumstances.
What's the difference between critical illness cover and income protection?
Income protection pays a regular monthly income for as long as you cannot work, regardless of diagnosis. Critical illness cover pays a one-off lump sum when you are diagnosed with a specified condition. They are complementary — most contractors benefit from having both.
