TL;DR
Switching UK private medical insurance to save money can be a costly mistake. Our expert WeCovr team, with experience in arranging over 900,000 policies of various kinds, explains why a cheaper premium might mean losing vital cover for past symptoms and conditions, leaving you exposed when you need it most.
Key takeaways
- Switching PMI solely on price can invalidate cover for symptoms you've had, even without a diagnosis.
- New policies often exclude pre-existing conditions, which can include symptoms you've recently seen a GP about.
- 'Moratorium' underwriting looks back 5 years, while 'Full Medical Underwriting' requires full disclosure upfront.
- Losing 'continued medical exclusions' (CME) terms means your new insurer won't cover conditions your old one did.
- An independent broker like WeCovr can safely compare policies to protect your continuity of cover.
At WeCovr, our experienced team helps thousands of people navigate the UK private medical insurance market. Having arranged over 900,000 policies of various types, we know that while everyone loves a good deal, the "switch and save" adverts you see online can hide a significant danger. Chasing a cheaper premium without expert guidance can lead to you unwittingly losing cover for health issues you thought were protected.
This article pulls back the curtain on the switching myth. We'll explain why a lower monthly payment can sometimes mean a catastrophic loss of cover, leaving you to face long NHS waiting lists or huge private medical bills for conditions you believed your insurance would handle.
Why cheaper premiums sometimes mean losing critical symptom cover
The fundamental promise of private medical insurance (PMI) is peace of mind. It’s a contract that says if you develop a new, treatable (acute) condition after your policy begins, you can bypass NHS queues and receive private care.
The problem arises when you switch policies. Your new insurer doesn't simply pick up where your old one left off. They will assess you as a new customer, and their primary concern is risk. That risk includes not just diagnosed illnesses but any symptom, consultation, or medication you've had in the past.
A cheaper premium from a new provider is often cheaper for a reason: the insurer has placed more restrictions on what they will cover. They might offer a lower price by excluding any health niggle you've ever mentioned to a doctor.
The core principle of UK PMI is crucial to understand: Private medical insurance is designed to cover new, acute conditions that arise after you take out your policy. It does not cover pre-existing conditions or long-term, incurable (chronic) conditions like diabetes or asthma. When you switch, what counts as "pre-existing" is reset, and that's where the danger lies.
Understanding How PMI Underwriting Works When You Switch
"Underwriting" is the process an insurer uses to evaluate your health and decide what they will and won't cover. When you switch providers, the type of underwriting you choose is the single most important factor in determining whether you keep your valuable cover.
There are three main types of underwriting for individuals and families in the UK:
1. Moratorium (Mori) Underwriting
This is the most common type for new policies because it's quick and doesn't require a long medical questionnaire.
- How it works: A moratorium policy automatically excludes any condition (and related symptoms) for which you have had symptoms, medication, or advice in the 5 years before the policy started.
- The "Rolling" Clause: The insurer will only agree to cover one of these pre-existing conditions if you go for a set period (usually 2 years) without any symptoms, treatment, or advice for it.
- The Switching Trap: If you switch from an old policy to a new moratorium policy, all your previous medical history is subject to this 5-year look-back. A knee twinge you had 3 years ago, which your original insurer would have covered if it flared up, will now be excluded by your new insurer for at least 2 years.
2. Full Medical Underwriting (FMU)
This involves full disclosure from the outset.
- How it works: You complete a detailed health questionnaire, declaring your entire medical history. The insurer's underwriters review it and state precisely what is excluded from your policy from day one.
- The Benefit: It provides clarity. You know exactly where you stand.
- The Switching Trap: If you forget to declare a consultation or symptom, even an innocent mistake, the insurer could refuse a future claim or even void your policy for "non-disclosure". It places the full burden of memory on you.
3. Continued Medical Exclusions (CME)
This is the gold standard for switching and the safest way to change provider. It is sometimes called 'switch' or 'protected' underwriting.
- How it works: A new insurer agrees to match the underwriting terms of your previous policy. They effectively take on your old policy's exclusions, rather than applying new ones. Any condition that was covered by your old insurer will be covered by your new one.
- The Benefit: It allows you to switch providers to access better benefits or a more competitive price without losing cover for your medical history.
- The Catch: Not all insurers offer CME terms, and there are often strict criteria (e.g., you can't have a pending claim or recent treatment). This is where using a specialist broker is vital, as we can negotiate these terms on your behalf.
Here is a simple table to compare the methods:
| Underwriting Type | How It Works | Key Risk When Switching |
|---|---|---|
| Moratorium (Mori) | Automatically excludes conditions from the past 5 years. | You lose cover for past symptoms that your old policy would have covered. |
| Full Medical (FMU) | You declare your full health history. Insurer lists exclusions. | Forgetting to declare a condition can void your policy. High burden of proof on you. |
| Continued Medical (CME) | New insurer accepts your old policy's exclusions. | Not always available. Requires expert negotiation to secure the right terms. |
The 'Pre-Existing Condition' Trap: More Than Just Diagnoses
One of the most common and costly mistakes people make is thinking a "pre-existing condition" is only something that has a formal name, like arthritis or gallstones.
In the world of insurance, a pre-existing condition is any illness, injury, or related symptom for which you have sought medical advice, received treatment, or experienced symptoms, whether a diagnosis was made or not.
Let's look at two real-life examples.
Example 1: Sarah's Recurring Back Pain
Sarah, 45, has had a PMI policy with Insurer A for 10 years. Two years ago, she had a few weeks of lower back pain, saw her GP who suggested painkillers, and it went away. Her renewal price from Insurer A increases by 15%. She sees a cheap deal online with Insurer B and switches to their moratorium policy to save £40 a month.
Six months later, the back pain returns, and it's much worse. Her GP suspects a slipped disc and refers her for an MRI scan. Insurer B requests her medical records, sees the GP visit two and a half years ago for back pain, and declines the claim. Because she had symptoms in the 5 years before her new policy started, it's considered a pre-existing condition.
Had she stayed with Insurer A, the MRI and subsequent treatment would likely have been covered as the issue arose long after her original policy began. By switching, she saved around £240 but now faces a £1,500 bill for the private scan and potentially thousands more for surgery.
Example 2: David's Investigations
David, 58, has a policy with Insurer C. He experiences some dizzy spells and his GP refers him to a cardiologist for an ECG to be safe. Everything comes back clear. A year later, he wants to switch to Insurer D on an FMU basis to get a better hospital list. On the application, he's asked if he's had any cardiovascular symptoms or investigations. He completely forgets about the dizzy spells and the clear ECG.
Three years later, he develops a genuine heart condition requiring surgery. During the claim process, Insurer D discovers the previous ECG. They argue that he failed to disclose relevant medical history and cancel his policy from the start date. He receives no payout for his surgery and has his premiums refunded, leaving him uninsured at the very moment he needs it.
These scenarios are not scaremongering; they are the unfortunate reality for many who switch without specialist advice.
The Safe Way to Switch: Using Continued Medical Exclusions (CME)
The only truly safe way to move your private medical insurance to a new provider is on a Continued Medical Exclusions (CME) basis.
CME underwriting is specifically designed to provide continuity of cover. It ensures you are not penalised for your medical history when you change insurers.
Here’s how it works in practice:
- You must have an existing PMI policy. CME is only for people who are already insured.
- You approach a new provider (ideally via a broker). Your broker will explain that you wish to switch on CME terms.
- The new insurer assesses your situation. They will ask for your current policy certificate, which details any personal exclusions. They may also have rules, such as not accepting anyone who has claimed in the last 12 months.
- The new insurer issues a policy. This new policy will have the exact same medical exclusions as your old one. If your old policy had no personal exclusions, your new one won't either.
This means if Sarah (from our example) had used a broker like WeCovr to switch, we would have approached Insurer B and insisted on CME terms. Her back pain would not have been a "new" pre-existing condition, and her claim would have been paid.
Key takeaway: Switching on a moratorium basis resets your medical history to zero. Switching on a CME basis protects it.
Comparing UK PMI Providers for Switching
Most major UK insurers recognise the need for continuity and offer a path for switching, but their rules and appetite for CME underwriting vary. An independent broker is essential as we have deep knowledge of which insurer is the best fit for your specific circumstances.
| Provider | Typical Approach to Switching | Key Considerations for Switchers |
|---|---|---|
| Bupa | Offers a 'protected underwriting' option for switches. | One of the most established providers. May have criteria around claims history and age. |
| AXA Health | Provides a clear 'switch' underwriting option (CME). | Known for comprehensive cover and strong hospital lists. Their pricing and terms will depend on your current cover. |
| Aviva | Offers Continued Personal Medical Exclusions (CPME) underwriting. | Strong overall provider. As with others, they will review your current policy terms before offering a switch. |
| Vitality | Offers 'continued underwriting' for those switching. | Known for its wellness programme. Switching can be a great way to access their rewards, but cover must be like-for-like. |
| WPA | Specialists in flexible and customer-focused policies, often accommodating switches. | A not-for-profit provider that can be very competitive, especially on CME terms. They will want to see your existing certificate of insurance. |
This table is a general guide. The availability of CME terms depends on your individual history, your current insurer, and the specific policy you hold. This complexity is why attempting a "DIY" switch is so fraught with risk.
Beyond Premiums: What to Consider When Changing Your PMI Policy
While protecting your medical history is paramount, a switch can also be an opportunity to reassess your cover. A cheaper premium on a new policy might be achieved by reducing benefits, not just by adding medical exclusions.
When comparing a potential new policy, even on CME terms, check the following:
- Hospital List: Does the new policy give you access to the same hospitals? Some cheaper plans use restricted lists that exclude prime central London or major regional hospitals.
- Excess Level: An excess is the amount you pay towards a claim. A higher excess lowers your premium, but make sure you can afford to pay it if you need to claim.
- Outpatient Limits: Does the policy limit the value (£500, £1,000) or number of pre-treatment consultations and tests? Your current policy might be unlimited.
- Cancer Cover: This is a critical area. Check for any caps on treatment, and ensure the cover is for the latest drugs and therapies approved by NICE.
- Mental Health Cover: The level of support for mental health varies enormously between insurers. Check limits for psychiatric treatment and therapy.
- Added Benefits: Many modern policies include valuable extras. For example, all WeCovr clients gain complimentary access to our AI-powered calorie and nutrition tracking app, CalorieHero, to support their health goals. We also offer discounts on other policies, like life or income protection, when you take out health insurance with us.

Switching an Employer PMI Policy
If you are leaving a company group scheme, the rules are slightly different. You often have the option to continue the policy on a personal basis with the same insurer, usually on a CME basis. This is a crucial right, as it allows you to maintain cover for conditions that may have developed while you were on the company scheme. Always talk to a broker before your employment ends to ensure you manage this transition correctly.

Do I need to declare symptoms I saw my GP for but didn't get a diagnosis?
What is the difference between a chronic and an acute condition?
If I switch my PMI policy, does my 'no claims discount' transfer?
The temptation to save money is understandable, especially with rising costs of living. But when it comes to your health and financial security, a cheap deal is not always a good deal. The "switch and save" myth can shatter your peace of mind when you need it most.
