IMPORTANT❗️
Our “best” insurer lists reflect our independent analysis of product features, service quality, and value. They are intended as a guide only – the right provider for you may differ depending on your needs and circumstances.
Finding the best Critical Illness Insurance in the UK can feel complex. Policies differ in how many conditions they cover, how they define those illnesses, and what additional benefits they include.
This 2026 guide reviews leading insurers side by side – highlighting claim rates, unique benefits and extra cover – so you can make an informed choice and secure the right protection for your circumstances.
What Do The Best Critical Illness Policies Cover?
The best Critical Illness policies will cover the widest range of conditions, with the option to add more. And some providers aren’t as strict when it comes to their definitions of each illness, meaning your claims are more likely to be successful. Most providers have a “core” policy and a “comprehensive” policy. Each one will offer a different extent of cover.
Core Critical Illness Cover
A core policy will tend to cost less and cover fewer conditions. The average number is typically around 35 or so critical illnesses. A core policy will cover conditions such as:
- Cancer (severe or advanced forms)
- Heart attack
- Stroke
- Alzheimer’s disease
- Parkinson’s disease, and Parkinson’s Plus syndromes
- Loss of a limb
- Major organ failure
- Permanent and irreversible loss of sight, hearing or speech.
Comprehensive Critical Illness Cover
Comprehensive policies can cover as many as 80 or 90 conditions in total. This might include 50 full conditions, which would pay out your total benefit. Insurers also tend to offer Critical Illness Cover for 30 or more less severe illnesses, which pay out a smaller, extra lump sum.
If you claim for one of these additional conditions, your full amount remains available for a claim in the future, should you need it. Comprehensive Critical Illness Cover often includes:
- Less advanced forms of cancer, such as carcinoma in situ of the breast, larynx, testicles and prostate
- Skin cancer
- Less severe heart surgeries
- Diabetes mellitus type 1
- Partial loss of hearing or sight.
Core Vs Comprehensive Cover: Which is Best?
We only ever recommend policies offering full cover to our clients. In our experience, the extra protection you get (for just a few pounds more per month) makes it more than worthwhile.
We’ve had people enquire with us about Critical Illness Cover and then apply on their own without taking advice. In one such case, a gentleman was sadly unable to claim for testicular cancer because he’d taken out a core policy for a lower premium. At the time, he wasn’t aware that less advanced forms of cancer weren’t normally covered by Critical Illness standard policies. We’re here to find you the right policy, so give us a call on 02084327333 or email help@drewberry.co.uk to talk through your options and get fee-free advice.
Which Critical Illness Insurance Is Best In 2026?
The UK has a few major Critical Illness providers to choose from, each with their own unique policy types, pricing structure, and underwriting process.
There’s no one-size-fits-all when it comes to insurance. The “best” product for you won’t necessarily be the best for someone else, as it all depends on your unique situation. That’s why it’s important to compare quotes and policies from different providers. And the cheapest quote isn’t always the best.

How To Choose The Best Critical Illness Cover
Finding the “best” Critical Illness Insurance will depend on your unique needs. Here are some aspects to consider.
Step 1: Think About Your Personal Circumstances
Your best Critical Illness policy depends on factors like:
- Whether you’re employed, self-employed, or a contractor
- Your existing cover, such as personal Income Protection or Critical Illness Cover through your employer
- Your family situation, and whether you’d want your children covered as well as yourself.
If you already have certain benefits, you might not need to double up on cover – but gaps are common, especially for the self-employed.
Step 2: Compare the Key Features
When comparing policies, look closely at:
- Maximum benefit
Most insurers will allow you to cover yourself for up to £3 million, but ranges vary depending on the provider
- Partial payouts
Some illnesses need to be of a certain severity (outlined in your policy documents) before an insurer will pay out. A number of providers offer partial payouts, paying out on a sliding scale if you don’t quite meet the definition for a full claim
- Policy definitions
Each insurer defines medical conditions differently, and some have better definitions than others. Most insurers need you to meet a certain severity or treatment in order to claim, but others may be more general. (However, all insurers must meet the ABI’s model definitions of conditions)
- Total permanent disability
This feature pays out if you become completely and permanently disabled. Most providers include this as standard, but others may charge extra
- Children’s cover
All providers offer the option to cover your children against critical illnesses – some as standard, others as a paid add-on. Be sure to check age limits too, as some insurers will stop cover at 18, while some go up to age 23
- Additional benefits
Most protection policies come with a suite of additional services included alongside your core cover. These usually include perks such as: Virtual GP services, mental health support, second medical appointments, and rehabilitation support – but will differ between providers.
Step 3: Understand the Cost
The price of Critical Illness depends on your age, health, benefit size, and policy type.
Premiums vary a lot between providers, so always get multiple quotes and make sure you’re comparing like-for-like. Check out our guide to the cost of Critical Illness Cover.
It’s crucial to understand what’s not covered before you buy, which is why we always recommend speaking to an independent adviser before taking out Critical Illness Insurance. It’s free to get our advice, and we’ll search the market to find you the most suitable policy for your needs. Call 02084327333 to chat through your options with one of our friendly advisers.
Which Critical Illness Insurance Companies Have The Best Payout Rates?
Another area to consider is the claims payout rate of a potential Critical Illness insurer. Claims stats are higher than most people think, most insurers publishing consistently high payout rates.
As you can see in the table below, in the last few years, nearly all insurers have paid out more than 90% of the claims they received.
IMPORTANT❗️
You shouldn’t use payout statistics alone to decide which insurer offers the best Critical Illness Cover. Instead, use them as a rough guide to compare successful claims across the industry as a whole.
How To Get The Best Critical Illness Insurance
You have two options when it comes to getting the best Critical Illness Cover policy. You can either go directly to an insurer, or buy cover through an adviser, such as Drewberry.
Go Direct To An Insurer – Best if You Know What Policy You Want
With this method, you’ll need to approach every UK insurer and compare quotes/policy details from all of them to get the best deal.
Once you have some figures, you’ll also need to compare Critical Illness policies by the number of conditions covered and the definitions used. This involves a lot of fine print, and needing to know medical and insurance jargon.
Get Independent Advice – Best if You Need Help Choosing
This is the smart choice. An independent adviser (like our Drewberry specialists) will consider your circumstances fully to make sure you get the best Critical Illness Cover for your needs.
We do all the hard work for you, comparing leading insurers on your behalf so you can be sure you’ve got the best deal for your needs. Where we provide a regulated advice service, we’re responsible for the advice we provide to you – giving you protection and peace of mind. Plus, you won’t pay us a penny.
What is Total Permanent Disability (TPD) Cover?
Total Permanent Disability Cover (TPD) pays out if you are left totally and permanently disabled and unable to work due to illness or injury.
To make a TPD claim, you must suffer a severe life-changing disability that has no medical prospect of improvement. There are fairly strict criteria to make a total permanent disability claim.
Can You Combine Critical Illness Cover With Life Insurance?
Yes, you can add Life Insurance to your Critical Illness policy, and we often recommend getting a policy that covers both.
The most popular option is to take out a Combined Life And Critical Illness policy. This means your policy will pay out in either event: death, or serious illness. Once your policy pays out, your cover will end unless you add life cover buyback. So if you claim for a critical condition, you’ll lose your life protection. But, it’s a cost-effective way of getting full Critical Illness Cover.
Separate Critical Illness And Life Insurance Policies
Another option is to take out two separate policies – one for serious illness cover only, the other for Life Insurance. In terms of cover, this option gives you the best of both worlds, paying out in either event. It also means that if you claim for a Critical Illness, you’ll keep your Life protection. But, this will cost a fair amount more than your other options.
Standalone Critical Illness Cover
Your other option is to take out Critical Illness Insurance only, with no Life Protection attached. Not all providers offer this option, as it’s less common. As a rule of thumb, we don’t tend to recommend standalone Critical Illness Cover unless you have ample Life Insurance elsewhere. Taking out a combined policy might cost a touch more, but it gives you more protection.
What's The Difference Between Critical Illness And Terminal Illness?
Terminal Illness Insurance is usually included free with Life Insurance. It pays the policy benefit early if the policyholder becomes terminally ill (where a doctor has said they have less than 12 months to live).
Critical Illness Insurance, on the other hand, pays out if you develop a critical illness of a specified severity, such as cancer, heart attack or stroke.
The two options sound similar but are in fact very different and not interchangeable. It’s possible to recover from a critical illness, for example, whereas that’s not the case after a terminal prognosis.
Do You Pay Tax On A Critical Illness Cover Payout?
No, you don’t typically pay tax on a Critical Illness Insurance payout. This is because you usually pay premiums from income you’ve already paid tax on, i.e. your wages. That means HMRC has already effectively taxed you once and therefore allows you to receive a Critical Illness Insurance claim tax-free.
Is Critical Illness Insurance Better Than Income Protection?
Critical Illness Insurance and Income Protection both pay a benefit if you become ill. It can therefore be hard to tell them apart or know which one would work best for you.
Critical Illness Insurance pays a lump sum of your choosing, while Income Protection Insurance pays a monthly benefit of a proportion of your earnings.
With Critical Illness Cover, to claim you must develop a critical condition in the policy at a severity your insurer dictates. On the other hand, Income Protection pays out simply if you can’t do your job after any accident or sickness. Learn more about the difference between Critical Illness Cover and Income Protection.
