As an FCA-authorised expert with over 800,000 policies of various kinds arranged, WeCovr understands the nuances of private medical insurance in the UK. This guide explores the crucial period when children become young adults, helping you navigate their health cover options to ensure they remain protected.
The journey from teenager to independent young adult is filled with milestones: finishing school, starting university, or landing a first job. Amid these changes, one question often puzzles parents: what happens to their private medical insurance (PMI)? The transition between the ages of 18 and 25 is a critical time for health cover. Decisions made now can impact their access to private healthcare for years to come.
This comprehensive guide will walk you through everything you need to know about PMI for dependents aged 18-25. We'll cover eligibility rules for family policies, the financial pros and cons, and the all-important process of transitioning to an individual policy without losing valuable cover.
Before diving into the specifics for young adults, it's vital to understand the role of private medical insurance in the UK today.
PMI is not a replacement for the National Health Service (NHS). The NHS provides excellent emergency care and treatment for chronic conditions, and it remains the bedrock of UK healthcare. Instead, PMI is a complementary service designed to cover the diagnosis and treatment of acute conditions.
Crucial Point: Standard UK private medical insurance policies do not cover chronic conditions or pre-existing conditions (illnesses or injuries you had before your policy began). Its purpose is to handle new, eligible health issues that arise after you take out the cover.
With NHS waiting lists remaining a significant concern—the elective care waiting list in England, for instance, has consistently hovered over 7.5 million treatment pathways in recent times according to NHS England data—many families see PMI as an invaluable tool. It provides peace of mind through:
For young adults, who are often focused on their studies or starting a career, the ability to bypass long waits and get back on their feet quickly can be particularly important.
Most parents prefer to keep their children on their family policy for as long as possible. It's often simpler and more cost-effective. However, insurers have specific rules about when a "child" becomes an independent "adult" in their eyes.
The most common factor determining eligibility is age and educational status.
Once a dependent leaves full-time education or reaches the insurer's final age limit, they will need their own policy to remain covered.
Here is an illustrative table of typical age limits from major UK insurers. Please note these are subject to change and policy-specific terms.
| Provider | Standard Dependent Age Limit | Extended Limit (in Full-Time Education) |
|---|---|---|
| Aviva | Up to age 20 | Up to age 24 |
| AXA Health | Up to age 20 | Up to age 25 |
| Bupa | Up to age 21 | Up to age 24 |
| Vitality | Up to age 25 (irrespective of education) | Not applicable |
This information is indicative as of early 2025. Always check the specific terms of your policy.
Keeping a young adult on a family policy is almost always more affordable than them taking out a standalone policy. The premium increase for adding a dependent is typically less than the cost of an entirely new plan.
Real-Life Example:
The Smith family has a policy for two adults. Their premium is £180 per month. Their son, Tom, turns 19 and is starting university. To keep him on their family plan, their premium increases to £230 per month—an extra £50.
If Tom were to seek his own individual policy with similar benefits, the quotes he receives are around £75 per month.
By keeping him on the family plan, the Smiths save £25 per month (£300 per year) while ensuring he has comprehensive cover.
Perhaps the most significant benefit of keeping a child on a family policy is the continuity of underwriting.
What is underwriting? It's the process an insurer uses to assess your health and medical history to decide the terms of your policy.
If your child has been on your policy from a young age, any medical conditions they developed during that time are likely covered. If they were to leave the policy and start a new one later, those same conditions would now be classed as "pre-existing" and would be excluded from cover.
Maintaining continuous cover is the best way to protect against future exclusions. This is why planning the transition off a family policy is so important.
The day will come when your grown child needs their own private health cover. This could be due to reaching the age limit, graduating, or starting their first full-time job. Managing this transition smoothly is key to ensuring they don't have a gap in cover or lose benefits they've accrued.
This is one of the most valuable but often overlooked features in the private medical insurance UK market. Many insurers offer a "continuation option" that allows a dependent leaving a family or group policy to start their own individual plan without any new medical underwriting.
This means:
This is a golden opportunity to lock in comprehensive cover. Missing the window to exercise this option (usually 30-90 days after leaving the old policy) means they would have to apply for a brand-new policy and face exclusions for any conditions they've developed over the years. An expert PMI broker, like WeCovr, can be indispensable in navigating these crucial deadlines and terms.
A standalone policy for a 20-something can feel like a daunting expense. However, modern PMI is incredibly flexible, and there are several ways to tailor a policy to make it highly affordable without sacrificing essential protection.
The excess is the amount you agree to pay towards the cost of a claim. For example, if you have a £250 excess and receive treatment costing £3,000, you pay the first £250 and the insurer pays the remaining £2,750.
A higher excess leads to a lower monthly premium. For a young and generally healthy person, opting for a £500 or even £1,000 excess can slash premiums, as they are less likely to make frequent claims.
| Example Excess Level | Estimated Monthly Premium (for a 22-year-old) |
|---|---|
| £100 | £65 |
| £250 | £58 |
| £500 | £50 |
| £1,000 | £42 |
Insurers group hospitals into tiers. A policy that gives you access to every private hospital in the UK, including the prime central London ones, is the most expensive.
Opting for a "guided" or "expert select" list can significantly reduce costs. With this option, the insurer provides a curated list of high-quality hospitals for any treatment. While it reduces choice, the hospitals are still excellent, and the savings can be substantial.
This is one of the most popular cost-saving measures in the UK. If you add the six-week option to your policy, it means that for inpatient treatment, if the NHS can treat you within six weeks of when the treatment is recommended, you will use the NHS. If the NHS wait is longer than six weeks, your private medical insurance kicks in.
Given that many urgent procedures on the NHS happen relatively quickly, this option provides a safety net against long waits while reducing your premium by as much as 25-30%.
Not every policy needs to be fully comprehensive. For a young adult, a more budget-focused plan can be a perfect starting point.
