As an FCA-authorised expert with experience in over 800,000 policies, WeCovr helps you navigate the UK private medical insurance market. While you can buy a policy almost instantly, "immediate cover" has important nuances. This guide reveals the truth about when your private health cover really begins.
In the digital age, we expect everything on demand. You can order a taxi, a takeaway, or a new television and have it within the hour. So, it’s natural to ask: can you get immediate private medical insurance cover?
The short answer is yes and no.
You can certainly purchase a private medical insurance (PMI) policy very quickly, sometimes in under an hour, especially online. Your policy document might state a start date of today. However, this does not mean you are instantly covered for every possible medical condition.
The reality is that all new private health cover in the UK comes with conditions, waiting periods, and exclusions. These are not designed to catch you out; they are fundamental to how insurance works, ensuring the system remains fair and affordable for everyone. The most significant restriction is that standard UK PMI is designed to cover new, acute conditions that arise after your policy begins. It does not cover long-term chronic illnesses or pre-existing conditions you already have.
Think of it like car insurance: you can’t buy a policy after you’ve had an accident and expect the insurer to pay for the repairs. Similarly, you cannot take out health insurance to cover a condition you are already aware of or receiving treatment for.
The process that determines what you are and aren't covered for from day one is called underwriting. This is the insurer's way of assessing risk. In the UK, there are two main types of underwriting for personal PMI policies. The one you choose has a massive impact on how "immediate" your cover truly is.
An expert PMI broker, such as WeCovr, can help you decide which option is best for your personal circumstances at no extra cost to you.
This is the most common and fastest way to get a policy started. With a moratorium, you don't need to provide your full medical history upfront. Instead, the insurer applies a blanket clause to your policy.
How it works: A moratorium typically excludes any medical condition for which you have experienced symptoms, sought advice, or received treatment in the five years leading up to your policy start date.
However, these conditions can become eligible for cover later on, provided you meet specific criteria. This is often called the "2-5-2" rule:
Example: Imagine you had physiotherapy for knee pain 3 years before buying your policy. Under a moratorium, your knees would be excluded from cover for the first 2 years of your policy. If, during those 2 years, your knee pain returns and you see a GP, the 2-year clock resets. If, however, you go 2 full years with no knee issues whatsoever, it could become eligible for cover in the future.
This is a more detailed, upfront process. With FMU, you are required to complete a comprehensive health questionnaire, declaring your full medical history. The insurance company's underwriting team will then review your application.
Based on your disclosures, they will decide one of three things for any pre-existing conditions:
Choosing the right underwriting is a critical decision. Here’s a simple table to help you compare:
| Feature | Moratorium (MORI) Underwriting | Full Medical Underwriting (FMU) |
|---|---|---|
| Application Speed | Fast. No initial medical questionnaire. | Slower. Requires a detailed health declaration. |
| Initial Certainty | Less certain. You may not know if a condition is covered until you claim. | Total certainty. You know exactly what is and isn't covered from day one. |
| Admin at Claim | More complex. Insurers will investigate your medical history when you make a claim. | Simpler. The insurer already has your history, so claims are often faster to process. |
| Cover for Pre-existing | Possible, but only after a 2-year clear period on the policy. | Unlikely. Conditions are typically excluded permanently from the outset. |
| Best For... | People with a clean bill of health seeking a quick start. | People with a complex medical history who want clarity on their cover. |
A fundamental principle of private medical insurance in the UK is that it is designed to treat acute conditions. It is not designed for the ongoing management of chronic conditions.
An Acute Condition: A disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. Examples include a hernia, appendicitis, cataracts, or a joint injury. The goal of the treatment is to return you to your previous state of health.
A Chronic Condition: A disease, illness, or injury that has one or more of the following characteristics:
Examples of chronic conditions include diabetes, asthma, high blood pressure, arthritis, and multiple sclerosis. While the NHS provides excellent ongoing care for these conditions, they are excluded from cover by standard PMI policies. A policy may cover the initial diagnosis of a chronic condition, but it will not cover the long-term management.
This is the single biggest source of confusion for new PMI customers. A pre-existing condition is any illness, injury, or symptom you had before your policy start date. This applies whether you were formally diagnosed or not. If you had symptoms or sought advice, it is considered pre-existing.
Standard UK private medical insurance does not cover pre-existing conditions.
This is a core rule across the entire market. The business model is based on insuring against unforeseen future risks, not paying for existing problems. How an insurer deals with your pre-existing conditions is determined by the underwriting method you choose (Moratorium or FMU).
It is vital to be completely honest during your application. Failing to disclose a condition, especially on an FMU application, could be considered non-disclosure and may lead to your policy being cancelled and claims being rejected.
Even with "instant" cover for new, acute conditions, most policies have specific waiting periods and general exclusions.
All insurance policies in the UK come with a statutory 14-day cooling-off period. During this time, you can cancel the policy for a full refund. While cover is technically active, it's wise not to plan any treatment during these first two weeks. Some insurers also impose their own initial waiting period of around 30 days where no claims can be made.
Beyond the initial period, some high-value benefits may have their own waiting periods before you can use them. This prevents people from buying a policy to immediately claim for a major, expensive treatment.
| Benefit Type | Typical Waiting Period | Notes |
|---|---|---|
| Outpatient Consultations | 0 - 30 days | For new conditions, this is often available immediately. |
| Musculoskeletal (MSK) | 0 - 30 days | Cover for joints, muscles, and bones. |
| Mental Health Treatment | 0 - 2 years | Some policies cover it from day one; others impose a significant wait. |
| Cancer Cover | 0 - 90 days | While diagnosis may be covered sooner, access to advanced drugs/therapies can have a wait. |
| Maternity Complications | 10 - 24 months | Standard pregnancy is not covered, but complications may be after this period. |
Every PMI policy has a list of standard exclusions. These are treatments and conditions that are never covered, regardless of when they occur. Common examples include:
Let's look at two examples to see how this plays out.
Sarah, 35, is healthy and active. She wants cover quickly and chooses a policy with moratorium underwriting. Her policy starts on 1st November.
David, 52, has a few minor health issues he wants to be clear about. He opts for FMU and uses WeCovr to help him complete the application. He declares a history of migraines and a bout of acid reflux five years ago.
The insurer reviews his application and offers him a policy with a specific, written exclusion for "investigation and treatment of headaches and migraines." They agree to cover the acid reflux as it was a one-off, historic event. David accepts. His policy starts on 1st November.
David had to wait a little longer for his policy to be approved, but he had complete peace of mind knowing exactly where he stood.
While truly "instant" cover for everything isn't realistic, you can take steps to get your policy in place efficiently and understand its limits from the get-go.
The best way to manage your health is to be proactive. While private medical insurance is an incredible tool for when things go wrong, focusing on wellness can reduce your need to claim. With NHS waiting lists in England reaching 7.54 million cases in April 2024, taking control of your health has never been more important.
