Navigating waiting periods is key to unlocking the value of private medical insurance in the UK. WeCovr, an FCA-authorised broker that has helped arrange over 900,000 policies, demystifies these delays for you. This guide explains how they work and how you can get treated faster.
Private Medical Insurance (PMI) is your passport to faster medical treatment, but it's not always an instant pass. Nearly all policies come with 'waiting periods' – a set amount of time you must hold your policy before you can claim for certain treatments.
Understanding these waiting periods is the single most important step in choosing the right policy. It determines when your cover kicks in and for what conditions. This guide will walk you through:
Let's unravel the timelines of private health cover so you can make a truly informed decision.
Think of a waiting period, sometimes called a 'deferment period', like a probation period for your health insurance policy. It's a fixed timeframe, starting from the day your cover begins, during which you cannot make a claim for some or all of the benefits included in your plan.
The purpose of these waiting periods is simple: to protect the insurance provider and its members from 'adverse selection'. This is where someone signs up for insurance because they know they need imminent, expensive treatment, only to cancel the policy once the treatment is complete.
If this were common practice, the cost of premiums would skyrocket for everyone. Waiting periods ensure the insurance system remains fair and financially sustainable by encouraging people to take out cover for future, unforeseen health issues, rather than immediate, known problems.
Before we go any further, it's vital to understand the fundamental principle of private medical insurance in the UK.
PMI is designed to cover
acuteconditions that ariseafteryour policy starts.
Similarly, pre-existing conditions – any illness or injury you had symptoms of, received advice for, or were treated for before your policy began – are typically excluded, at least for an initial period. This is where the most common type of waiting period comes into play.
Waiting periods aren't one-size-fits-all. They vary by provider, policy type, and the specific medical benefit. Here are the most common waiting periods you'll encounter.
| Benefit Category | Typical Waiting Period | Why it Exists |
|---|---|---|
| Pre-existing Conditions (Moratorium) | 24 months (symptom-free) | Prevents claims for known, recent health issues. |
| Cancer Cover | Often from Day 1 | A key selling point; insurers compete on this. |
| Maternity / Pregnancy Care | 10 to 24 months | Ensures policy is taken for long-term health, not just for a planned pregnancy. |
| Dental & Optical Care | 3 to 6 months | Prevents immediate claims for known dental or vision needs. |
| Psychiatric Treatment | Varies (0-24 months) | Depends on the level of cover and underwriting. |
| Initial Policy Deferment | 14 to 30 days | Some policies have a short initial period where no new conditions can be claimed for. |
The most significant waiting period in UK PMI is the moratorium. This is directly linked to pre-existing conditions.
With moratorium underwriting (the most popular type), you don't need to provide a full medical history when you apply. Instead, the insurer applies a simple rule:
Any medical condition you've had symptoms of, taken medication for, or sought advice on in the 5 years before your policy start date is excluded from cover for the first 2 years of your policy.
However, if you complete this 2-year period without experiencing any symptoms, needing any treatment, or seeking any advice for that specific condition, it will likely become eligible for cover from that point onwards.

The type of underwriting you choose has the biggest impact on your waiting periods. Underwriting is simply the process an insurer uses to assess your health risk before they agree to cover you.
There are two main paths in the UK:
As explained above, this is the "wait-and-see" approach. It's quick to set up and requires no medical forms. The trade-off is the 2-year waiting period for any pre-existing conditions from the past 5 years.
With FMU, you complete a detailed health questionnaire, declaring your entire medical history. The insurer's medical team reviews it and makes a decision from day one. They might:
The main advantage of FMU is certainty. You know exactly what is and isn't covered from the moment your policy starts. There's no 2-year guessing game.
| Feature | Moratorium Underwriting | Full Medical Underwriting (FMU) |
|---|---|---|
| Application Process | Fast and easy, no forms needed. | Longer, requires a detailed health questionnaire. |
| Pre-existing Conditions | Automatically excluded for 2 years. May be covered after that. | Assessed individually. May be covered or permanently excluded. |
| Clarity of Cover | Less certainty at the start; "wait and see". | Complete clarity from Day 1. |
| Premiums | Can sometimes be slightly cheaper initially. | Can be higher or lower depending on your health history. |
| Best For | People with few or no recent health issues who want a quick start. | People who want certainty, or have old medical issues they want assessed upfront. |
Deciding between these two can be tricky. An expert PMI broker, like our team at WeCovr, can talk through your medical history and help you decide which underwriting method will give you the best outcome.
Waiting periods are standard, but they're not always set in stone. With the right strategy, you can significantly reduce your waiting time or even get covered from day one.
This is the most effective way to avoid starting from scratch. If you already have private medical insurance, you don't have to be stuck with your current provider if you're unhappy with the price or service.
Insurers offer special terms for switchers, known as Continued Personal Medical Exclusions (CPME) or "switch" underwriting.
Under a CPME switch:
This is a complex process where professional advice is essential. A broker can ensure the switch is seamless, with no gaps in cover, and that your new insurer honours the "no new waiting periods" agreement.
As discussed, FMU provides clarity from the start. While it might result in a permanent exclusion for a specific past issue, it removes the 2-year moratorium waiting period for everything else. For many, this certainty is worth it.
Group private medical insurance policies, offered by employers, often have more generous terms than individual plans. The best type of group underwriting is called Medical History Disregarded (MHD).
On an MHD scheme, the insurer agrees to cover all eligible acute conditions, regardless of your pre-existing medical history. There are no moratoriums and no medical questionnaires. This is a huge benefit typically available to employees of larger companies. If your workplace offers a PMI scheme, it's often the best way to get comprehensive cover with no waiting periods for past issues.
While you can't always avoid a moratorium, you can choose a policy that offers strong day-one cover for major risks. Most high-quality UK PMI policies now offer full cancer cover from the day your policy starts. This "Cancer Cover Promise" is a key feature to look for and provides immense peace of mind.
It's important to remember that PMI is designed to work alongside the fantastic care provided by our NHS. It is not a replacement for it.
Where PMI shows its true value is in bypassing the waiting lists for planned, non-emergency treatment. As of 2024/2025, NHS waiting lists in England remain a significant concern, with millions of people waiting for consultant-led elective care. For an eligible acute condition, PMI allows you to:
This speed and choice are the core benefits of private health cover, allowing you to get back to work, family, and life much faster.
While insurance is there for when things go wrong, the best strategy is to stay healthy. A proactive approach to your wellbeing can not only reduce your risk of needing medical treatment but can also help you get better terms on your insurance.
By maintaining a healthy lifestyle, you increase the chances of sailing through a 2-year moratorium period without any pre-existing conditions flaring up, meaning you'll have broader cover sooner.
