Having a pre-existing medical condition rarely stops you getting protection insurance in the UK, it usually affects the terms instead. Most people are still able to protect their family with life insurance, critical illness cover or income protection, though the price of the conditions of the policy may change. The outcome depends on your condition, how well it is managed, and which insurer you apply to, and it can widely vary from one insurer to the next. Understanding how medical underwriting works, and getting the right guidance, is the single most useful thing you can do before applying.
This guide explains your options, how underwriting decisions are reached, which types of cover suit families with a health history, and the clear next steps to take.
Can you get protection insurance with a pre-existing condition?
In most cases, yes. A pre-existing condition is far more likely to change the terms of your cover than to rule it out altogether. Insurers assess the risk your condition represents and adjust accordingly, most often by charging a higher premium or by adding an exclusion for the related condition. Only in more severe or very recent cases is cover declined, and even then a decline from one insurer does not mean every insurer will say no.
The reason this matters is that two insurers can reach completely different decisions on the same person. One might offer standard terms, another a loading, another an exclusion. Knowing this, and comparing the market rather than accepting the first answer, is what makes the difference.
What counts as a pre-existing condition?
A pre-existing condition is any diagnosed physical or mental health condition you have, or have had, before applying for cover. It ranges widely in how it affects an application, from conditions that have little or no impact to those that need careful underwriting. Common examples include:
- Heart and circulatory conditions
- A history of cancer
- Stroke or transient ischaemic attack (TIA)
- Diabetes, both Type 1 and Type 2
- Mental health conditions such as anxiety and depression
- Respiratory conditions such as asthma and COPD
- A high BMI, often assessed alongside other factors
Whether and how a condition affects your cover depends less on the label and more on the detail: how severe it is, how well it is controlled, how recently it was diagnosed or treated, and whether it is stable, improving or worsening.
The main types of protection insurance
There are several types of cover, and families often combine more than one. The right mix depends on what you need to protect.
Life insurance pays a lump sum if you die during the policy term, most often used to clear a mortgage or provide for your family. With a medical condition, this is usually the most accessible cover, and a premium loading is the most common adjustment.
Critical illness cover pays a tax-free lump sum if you are diagnosed with a defined serious illness. It is the hardest of the three to arrange with certain conditions and is more likely to carry an exclusion for your specific condition.
Income protection replaces part of your income if injury or illness stops you working. With a health history it often comes with an exclusion for your condition, while still covering you for every other cause of incapacity.
Family income benefit is a form of life cover that pays your family a regular tax-free income rather than a single lump sum, which can be easier to budget around.
Over 50s guaranteed acceptance plans ask no health questions and cannot be declined. The payout is limited and they are not a substitute for underwritten cover, but they can be a fallback where health makes other cover difficult.
How medical underwriting works
Underwriting is the risk assessment process an insurer used to price your policy. When you apply, you answer questions about your health, family medical history, occupation and lifestyle. For someone in good health this is often instant. Where there is a medical condition, the application is assessed in more detail, sometimes by a specialist underwriter, and the insurer may request further evidence.
What insurers assess:
- Severity and control – How serious the condition is and how well it is managed. For diabetes for example, they look at your latest HbA1c reading. For many conditions, good control points to a better outcome.
- Treatment and medication – What treatment you have had and whether it’s working, which shows the condition is being managed.
- Time since diagnosis, treatment or last symptoms – For cancer, time in remission is key. For mental health, time since your last episode matters.
- Impact on daily life – Whether you can go to work and go about your daily activities without difficulty.
- Your general health and lifestyle – assessed as a whole.
To confirm the picture, an insurer may ask for a report from your GP or a relevant consultant, access to your medical records, or occasionally a nurse screening. Where a report is requested, the insurer usually meets the cost. For more detail, see our guide to how underwriting affects UK protection insurance options.
The five underwriting outcomes
Underwriting a medical condition usually leads to one of five outcomes.
| Outcome | What it means |
| Standard terms | The same premium as someone without the condition. Common for mild, well-controlled or historic conditions. |
| A loading | Cover at a higher premium reflecting the added risk. The most common outcome, and you remain fully covered, including for your condition. |
| An exclusion | A policy that excludes claims relating to your specific condition. More common on critical illness cover and income protection. |
| Postponement | The insurer delays a decision until your health is more stable, for example after a recent diagnosis or event. |
| Decline | Cover is not offered at this time. Less common, and never the end of the road, as another insurer may take a different view. |
A key distinction is between a loading and an exclusion. A loading means a higher price with full cover. An exclusion means a lower price but no cover for claims relating to your condition. Loadings are more common on life insurance, exclusions on critical illness and income protection. For complex histories, a specialist approach can be the difference between a workable policy and a decline, which we cover in our guide to impaired risk underwriting.
How common conditions are assessed
Every case is individual, but these are the general patterns, with more detail on our condition specific pages.
Heart Conditions
Heart conditions are underwritten cautiously, with the outcome shaped by the diagnosis, treatment and how stable things have been. Life cover is usually available with a loading, while critical illness and income protection often carry a cardiovascular exclusion. See protection insurance for heart conditions.
Cancer
A history of cancer depends heavily on the type, stage and time in remission. Life cover is often available with a loading that reduces over time, while critical illness cover frequently comes with a cancer exclusion. See protection insurance after cancer.
Stroke and TIA
Histories of strokes or TIA typically lead to a loading on life cover and exclusions on critical illness and income protection, with the time since the event being decisive. For more information on protection insurance after a stroke.
Diabetes
Diabetes that is well controlled, with stable readings and no complications, is regularly accepted on standard or modestly loaded terms.
Mental Health Conditions
Mental health conditions that are mild and well managed are frequently accepted on standard or lightly loaded terms, while more significant histories may attract a loading or an exclusion on income protection.
High BMI
Having a high BMI often results in a loading, and a very high BMI alongside other risk factors can lead to postponement or decline with some insurers.

Protecting your family
For most families, the point of protection insurance is to make sure that a health event does not become a financial crisis as well. A few things are worth thinking through.
How much cover you need
A common starting point is enough to clear the mortgage and other debts, replace lost income for as long as your family would need it, and cover the cost of raising any children.
Single or joint policies
Couples can take out separate single policies or a joint policy. Two single policies cost a little more but provide two payouts and more flexibility, which is often the better choice for families.
Writing your policy in trust
Placing life cover in trust generally means the payout goes quickly to your chosen beneficiaries and usually sits outside your estate for inheritance tax. It is straightforward to set up and costs nothing to add.
Children’s cover
Many critical illness policies include cover for your children as standard, which is worth checking when you compare.
Why honest disclosure matters
You have a legal duty, under the Consumer Insurance (Disclosure and Representations) Act 2012, to take reasonable care not to make a misrepresentation when you apply. In plain terms, answer every question fully and accurately.
This matters because a claim is often made years after the policy started. If an insurer later finds that a relevant condition was not disclosed, it can reduce the payout, refuse the claim, or void the policy. It is always better to disclose a condition and accept a small loading or exclusion than to leave it off and risk the cover failing when your family needs it most.
What you can do to improve your outcome
Disclose everything clearly
Full, well-presented information helps an underwriter assess you fairly rather than cautiously.
Gather your details
Diagnosis dates, current medication and recent test results all help your application.
Manage what you can
Well-controlled conditions and improved risk factors, such as blood pressure, cholesterol, weight and stopping smoking, support better terms.
Don’t apply to multiple insurers at once
Each application is assessed separately, and a string of declines can work against you.
Get indicative terms first
A specialist broker can approach underwriters informally to gauge the likely outcome before any formal application, so you’re not guessing.
How a specialist broker helps
With a medical condition, the differences between insurers are significant and largely hidden from price comparison sites. A specialist broker works for you, not the insurer.
They know which insurers take the most favourable view of specific conditions, how to present your application in its best light, and which exclusions to watch for. They can seek indicative terms informally, then compare real offers across both mainstream and specialist insurers on price and terms, so your decision rests on actual quotes rather than guesswork. Being loaded or declined by one insurer does not mean the whole market will say no.
Your next steps
- Note down your condition details, including diagnosis dates, treatment, current medication and recent results.
- Decide what you most need to protect, whether that is your mortgage, your family’s income, or a lump sum on diagnosis.
- Speak to a specialist broker for free, impartial advice and indicative terms before making any formal application.
- Compare the real offers on both price and terms, not just the headline premium.
- Put your cover in place, and consider writing it in trust for your family.

Frequently asked questions
Can I get life insurance with a pre-existing condition?
Usually yes. A condition more often changes the price or terms than rules cover out. The outcome depends on the condition, how well it is controlled, and which insurer you apply to.
What is the difference between a loading and an exclusion?
A loading is a higher premium with full cover. An exclusion keeps the price lower but removes cover for claims relating to your specific condition. Loadings are more common on life insurance, exclusions on critical illness and income protection.
Do I have to disclose a minor condition?
Yes. You have a legal duty to take reasonable care not to make a misrepresentation. Disclosing fully protects your policy and your family’s claim, and a small loading or exclusion is far better than a refused claim later.
Does a declined application affect my credit score?
No. A decline does not appear on your credit file, and there is no single public register of declined applicants. However, many applications ask whether you have previously been declined, loaded or excluded, and you must answer honestly.
Why do insurers quote such different terms for the same condition?
Each insurer sets its own underwriting rules and risk appetite. One may load or decline a case that another accepts on competitive terms, which is why comparing insurers, ideally through a specialist broker, matters so much.
Which type of cover is best if I have a health condition?
It depends on what you need to protect. Life insurance is usually the most accessible and suits mortgage and family protection. Income protection safeguards your earnings. Critical illness cover provides a lump sum on diagnosis. Many families combine them, and a broker can help you prioritise affordably.
