As an FCA-authorised broker that has helped arrange over 900,000 policies, we at WeCovr know that understanding private medical insurance (PMI) in the UK can feel like learning a new language. Policy documents are filled with specific terms that can be confusing. This guide is here to change that.
We've created the definitive glossary for 2026 to demystify the jargon, helping you compare quotes and choose your private health cover with total confidence.
Navigating the world of private health insurance is much simpler once you grasp the key concepts. Think of this glossary as your personal translator. We'll break down everything from the fundamental principles of cover to the specifics of making a claim, using simple language and real-world examples.
These are the building blocks of every PMI policy. Understanding them is the first step to becoming an informed buyer.
An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. Private medical insurance in the UK is specifically designed to cover acute conditions that arise after you take out your policy.
A chronic condition is a disease, illness, or injury that has one or more of the following characteristics:
Crucially, standard UK private health insurance does not cover the management of chronic conditions. This is the single most important exclusion to understand.
This refers to any illness, disease, or injury for which you have experienced symptoms, received medication, or sought advice from a medical professional before the start date of your policy. This applies whether you received a formal diagnosis or not.
Also known as 'private health insurance' or 'private health cover', PMI is an insurance policy that pays for the costs of private medical treatment for eligible acute conditions. Its primary purpose is to help you bypass NHS waiting lists and give you more choice over your care, such as choosing your specialist and hospital.
According to data from late 2025, NHS waiting lists in England continue to present a significant challenge, with millions of treatment pathways awaiting commencement. This pressure on the public system is a key reason why over 11% of the UK population opts for private medical insurance.
The person who owns the insurance policy and is responsible for paying the premiums. This may also be your employer if you are covered under a company scheme.
A person added to the main policyholder's plan, typically a spouse, partner, or children. Each dependant will be covered under the same policy terms, but adding them will increase the premium.
The regular amount of money you pay to the insurer to keep your policy active. You can usually choose to pay this monthly or annually. Paying annually often comes with a small discount.
Underwriting is the process an insurer uses to assess your risk and decide on the terms of your policy, including what will be excluded. There are two main types for new policies.
This is the most common and simplest type of underwriting. You don't need to provide a detailed medical history upfront. Instead, the insurer applies a blanket exclusion for any pre-existing conditions you've had in the last 5 years.
Here’s the key part: if you then go for a set period (usually 2 years) after your policy starts without having any symptoms, treatment, or advice for that condition, the insurer may automatically start covering it.
With FMU, you complete a detailed health questionnaire as part of your application. You must disclose your full medical history. The insurer's underwriting team will then review this information and may decide to apply specific, permanent exclusions to your policy from day one.
| Feature | Moratorium (Mori) Underwriting | Full Medical Underwriting (FMU) |
|---|---|---|
| Application Process | Quick and simple, no medical forms. | Longer, requires a full health questionnaire. |
| Pre-existing Conditions | Automatically excluded for a set period (usually 5 years). | Declared upfront and assessed individually. |
| Clarity on Cover | Can be uncertainty at the point of claim. | You know exactly what is excluded from day one. |
| Cover for Old Conditions | May become eligible for cover after 2 claim-free years. | Exclusions are often permanent. |
| Claims Process | Can be slower as the insurer may need to investigate your medical history. | Often faster as exclusions are already defined. |
An expert PMI broker like WeCovr can talk you through these options and advise which is most suitable for your personal circumstances, ensuring there are no surprises down the line.
If you already have a PMI policy and want to switch to a new insurer, CPME underwriting allows you to carry over your existing medical exclusions. This is beneficial because it means you won't have to start a new moratorium period, and conditions that were already covered by your old policy will continue to be covered by the new one.
A PMI policy is built from core cover and optional extras. Understanding the difference is key to tailoring a policy that fits your needs and budget.
This is the core of almost every private medical insurance policy in the UK.
All PMI policies cover in-patient and day-patient treatment as standard.
This covers medical care that does not require a hospital bed. This is one of the most important optional extras to consider.
Most insurers offer different levels of out-patient cover, from a set monetary value (e.g., £500, £1,000) to fully comprehensive cover.
This is a vital component of modern PMI. While all policies include a level of cancer cover, the comprehensiveness can vary significantly. Key things to look for include:
Given the sensitivity of this cover, it's crucial to compare what different providers offer.
Increasingly recognised as essential, mental health cover provides funding for the treatment of acute mental health conditions.
Often an optional add-on, this covers treatments designed to aid recovery from an acute condition. It typically includes:
There is usually an annual limit on the number of sessions you can claim for.
These terms define the financial boundaries of your policy and what it will not pay for.
The excess is a fixed amount you agree to pay towards a claim. For example, if you have a £250 excess and make a claim for a £3,000 procedure, you would pay the first £250, and the insurer would pay the remaining £2,750.
This is the maximum total amount your insurer will pay out for all your claims in a single policy year. Many comprehensive policies now offer an 'unlimited' benefit limit, but cheaper policies may cap this at a certain level (e.g., £20,000).
Every policy has a list of standard exclusions—treatments and conditions that are never covered. It's vital to read these.
| Commonly Excluded Treatments & Conditions |
|---|
| Pre-existing and Chronic Conditions |
| Normal Pregnancy and Childbirth |
| Cosmetic Surgery (unless for reconstruction after an accident/cancer) |
| Fertility Treatment (IVF) |
| Organ Transplants |
| Emergency/A&E services (these are handled by the NHS) |
| Drug and Alcohol Abuse Treatment |
| Self-inflicted injuries |
Insurers have agreements with networks of private hospitals. The list of hospitals you can use is determined by your policy choice. This has a major impact on your premium.
Similar to car insurance, most PMI providers operate a No-Claims Discount scheme. For every year you don't make a claim, you get a discount on your premium at renewal, up to a maximum level (e.g., 70%). If you do make a claim, your NCD level will likely be reduced, increasing your future premiums.
This is a popular cost-saving feature. If you add the 6-week option to your policy, you agree to use the NHS for in-patient treatment if the NHS waiting list for that procedure is less than six weeks. If the wait is longer than six weeks, your private cover kicks in. This can significantly reduce your premium because you are sharing some of the risk with the NHS.
Knowing the steps to take when you need to use your insurance is essential.
The best PMI providers now offer more than just medical cover. These benefits are designed to support your day-to-day health and wellbeing.
