Private Medical Insurance vs Cash Plans? Here’s what you need to know

If you start looking into private healthcare, you’ll quickly discover there isn’t just one type of product or approach.

Depending on where you look, you might come across:

• health cash plans
• traditional private medical insurance (PMI)
• self-paying privately when needed (also referred to as self-insuring)

Each of these approaches does something slightly different and the terms are not interchangeable. Understanding the difference matters, particularly in your 60s and 70s, when your healthcare needs, and financial priorities, begin to shift.

Below is a short guide to the main options you’re likely to come across so you can see what approach aligns best with your expectations and priorities.

‍

1. Health Cash Plans

Health cash plans are designed to help with managing routine, day-to-day routine health expenses.

Typically, they allow you to claim back money towards things like:

• Dental check ups and treatment
• Eye tests, contact lenses and glasses
• Physiotherapy and complementary therapies

Depending on the provider, there may be additional services included, such as helplines or access to other wellbeing benefits.

The core idea is simple: you pay a fixed monthly premium, and in return you receive a set allowance each year towards predictable healthcare costs.

Why do people like them?

• Predictable monthly cost
• Straightforward and practical
• If you regularly use the included benefits and claim your full allowance, they can represent good value for money.

However, it’s important to understand what they are not designed to do.

Cash plans don’t typically cover major private hospital treatment, expensive scans, or significant surgery. For larger health issues, most people would rely on the NHS or choose to pay privately themselves.

Cash plans help with managing everyday healthcare costs, not major financial shocks.

2. Traditional Private Medical Insurance (PMI)

Private medical insurance, often referred to and abbreviated as PMI, is what most people think of as “health insurance.” 

It is designed to cover the cost of private medical treatment for acute medical conditions and depending on the policy terms may include:

• Specialist consultations
• Diagnostic tests and scans
• Hospital treatment, hospital stays and surgery
• Private cancer treatment 

Why do people like them?

• Unlike a cash plan, PMI insures larger health issues so if a significant medical event occurs, the insurer pays according to the policy terms.
• For many people, PMI provides reassurance and access to private care without needing to draw directly from savings.

A key consideration, especially in later life, is the cost and affordability of the insurance premiums.

As we age, the likelihood of needing treatment increases. Premiums reflect that risk. Some people choose to maintain their comprehensive cover despite rising costs. Others reduce benefit levels, increase excesses or reduce hospital coverage to manage affordability.

Traditional PMI plans usually offer broad protection but are typically designed as comprehensive cover, and priced accordingly.

3. Paying Privately When You Need It

Another approach is to have no private health insurance policy at all and instead self-fund if treatment is needed. 

This approach can also be called ‘self-insuring’ as you are responsible for any private healthcare bills if you choose to receive care in a private setting. 

If you require a private consultation, scan or procedure, you draw down from cash, savings or investments to fund it.

Why do people like it?

• No ongoing premiums. There’s no monthly commitment if you don’t use private care.
• Full flexibility. You choose when and where to access private medical treatment.
• No exclusions or policy wording to navigate. There’s no uncertainty about whether something is covered.
• No renewal risk. You’re not exposed to rising premiums or changes in cover over time.
• Creates the option to mix and match between private and NHS treatment as you so choose.

For those with substantial accessible assets, this can feel sensible and controlled. However, healthcare spending in later life is rarely smooth. You might have several years with little or no private spend and then face significant costs in a short period of time.

Common elective procedures can cost thousands, sometimes tens of thousands, of pounds. Importantly you will have no support mechanism for determining what treatment to have and where.

Self-funding works best when you are comfortable with variability and confident that larger, unexpected expenses won’t materially affect your long-term plans (or that you will revert to the NHS for these) as well as having a clear understanding of how to access different treatment options.

How to Choose the Right Private Healthcare Option for You

There isn’t a single “correct” approach.

The right choice depends on:

• Your financial position
• Your attitude to risk and unpredictability
• How much certainty you value
• How comfortable you are relying on the NHS for larger treatments

With a cash plan, you may be content managing routine healthcare costs while relying on the NHS for more significant care.

With comprehensive PMI, you may prioritise peace of mind and broader private access, accepting higher premiums in exchange for coverage.

With self-funding, you may prefer flexibility and be prepared to draw down from savings if needed.

The important thing is that your decision reflects your priorities at this stage, rather than defaulting to what feels familiar or what you might have had during your working life.

Private Healthcare, Designed for Later Life

For some people in their 60s and 70s, none of the traditional options feels quite right.

They may not want:

• To pay for comprehensive cover they may never fully use
• To rely entirely on the NHS for procedures that could affect their quality of life
• To face open-ended financial exposure by drawing down large sums from savings by self insuring
• Or to focus primarily on routine, everyday expense reimbursements if those aren’t their main concern

For some, the goal is simply to reduce the risk of facing large, unexpected private healthcare bills without committing to the cost of full comprehensive PMI.

At Lateral, this thinking underpins our Lateral Health Plan. It was built specifically for people in their 60s and 70s who want a more deliberate approach to healthcare financing and navigation designed to offer an alternative to both comprehensive PMI and open-ended self-funding.

Rather than covering everything, or only reimbursing routine costs, our model focuses on:

• Insurance cover for common later-life procedures that impact quality of life
• Support when navigating both NHS and private options
• Predictable annual premiums with clear coverage and benefit limits
• Preventative engagement, including annual health checks, nutrition and physiotherapy support

Whether this approach suits you depends on your priorities and financial situation. But if none of the traditional options feel like a natural fit, it may be worth exploring whether a more tailored model makes sense for you.
