Is a Cash Plan enough? We compare £20-a-month top-up schemes (covering Dental & Optical) against full surgical insurance
For many UK families, the question isn't if they need extra health support, but what kind and at what cost. With NHS waiting lists reaching record highs—projected to remain a significant concern into 2026—families are rightly exploring their options.
Two popular choices dominate the market:
- Health Cash Plans (or 'NHS Top-Up' plans): Low-cost schemes that give you money back for everyday health expenses like dental check-ups, new glasses, and physiotherapy.
- Full Private Medical Insurance (PMI): Comprehensive insurance designed to cover the high costs of private diagnosis, surgery, and advanced treatments for acute medical conditions.
They sound similar, but their purpose, coverage, and cost are worlds apart. A cash plan won't pay for a £15,000 knee replacement, and full PMI won't typically cover your annual dental scale and polish. Understanding this difference is the single most important step in protecting your family effectively. (illustrative estimate)
This article will definitively compare both options, helping you decide whether a simple £20-a-month cash plan is sufficient, or if full surgical insurance is a necessary investment for your family's peace of mind.
What is a Health Cash Plan (NHS Top-Up)?
A health cash plan is a simple, budget-friendly insurance policy. It's not designed to replace the NHS or cover major surgery. Instead, a health cash plan helps you pay for routine healthcare.
You pay a fixed monthly premium, typically starting from as little as £10 to £30 for a family. In return, you can claim back a set amount of cash each year for specific treatments.
How it works in practice:
- Illustrative estimate: You take your child for a dental check-up costing £60.
- You pay the dentist upfront.
- You submit the receipt to your cash plan provider via their app or website.
- Illustrative estimate: They refund you the cost, up to the annual limit for that benefit (e.g., up to £150 per year for dental).
Key Features of a Health Cash Plan:
- Affordability: Premiums are low and fixed, making them easy to budget for.
- Predictable Payouts: You know exactly how much you can claim back for each category per year.
- Broad, Everyday Coverage: Most plans cover dental, optical, physiotherapy, osteopathy, and sometimes even prescriptions and health screenings.
- No Medical Questions: In most cases, you can join without a medical examination, and pre-existing conditions don't prevent you from using benefits like dental or optical.
Typical Health Cash Plan Benefits (Example for a Family Plan ~£25/month)
| Benefit Category | Annual Limit Per Person | Typical Use Case |
|---|---|---|
| Dental | £150 - £250 | Check-ups, fillings, hygienist visits, crowns. |
| Optical | £150 - £250 | Eye tests, glasses, contact lenses. |
| Physiotherapy | £200 - £400 | Sessions for a sports injury or back pain. |
| Consultations | £250 - £500 | Seeing a specialist after a GP referral. |
| Health Screening | £150 | Annual health check-up at a private clinic. |
| Prescriptions | £40 | Reclaiming the cost of NHS prescription charges. |
The Verdict on Cash Plans: Health cash plans are excellent for managing predictable, routine health costs. They are a smart budgeting tool, not a safety net for serious illness. They "top up" the services you get on the NHS by making private routine care more affordable.
What is Full Private Medical Insurance (PMI)?
Private Medical Insurance (PMI), also known as private health cover, is a completely different proposition. Its primary purpose is to cover the cost of private medical treatment for acute conditions that arise after you take out the policy.
An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. Examples include cataracts, joint replacements, hernias, and most types of cancer.
Crucially, standard UK PMI does not cover:
- Chronic conditions: Long-term illnesses that cannot be cured, only managed (e.g., diabetes, asthma, high blood pressure). The NHS remains your primary provider for these.
- Pre-existing conditions: Any illness or injury you had symptoms of, or received treatment for, in the years before your policy started (typically the last 5 years).
How PMI works in practice:
- You experience persistent knee pain and your GP suspects a torn meniscus. The NHS waiting list for an MRI is 12 weeks, and the surgical list is 18 months.
- You contact your PMI provider, who arranges a private MRI scan within a few days.
- The scan confirms the diagnosis. Your insurer authorises surgery with a specialist at a private hospital of your choice.
- You have the operation within a few weeks. The insurer pays the hospital and surgeon directly, which could be a bill of over £15,000.
Key Features of Full PMI:
- Bypass NHS Queues: Get prompt access to specialist consultations, diagnostic scans (MRI, CT, PET), and surgery.
- Choice and Control: Choose your specialist, your hospital, and schedule treatment at a time that suits your family.
- Access to Advanced Care: May include new cancer drugs or treatments not yet available on the NHS.
- Comfort and Privacy: Treatment is typically in a private hospital with an en-suite room.
The Verdict on PMI: PMI is comprehensive insurance for the unexpected and serious. It provides a safety net against long waits and gives you control over your treatment for new, curable conditions. It is a significant financial commitment but offers unparalleled peace of mind.
Head-to-Head: Health Cash Plan vs. Full Health Insurance
To make the choice crystal clear, let's compare the two side-by-side. This table summarises the fundamental differences every family needs to understand.
| Feature | Health Cash Plan (NHS Top-Up) | Full Private Medical Insurance (PMI) |
|---|---|---|
| Primary Goal | Budgeting & Cashback: Helps you afford routine, out-of-pocket health costs. | Treatment & Surgery: Pays for private treatment of new, acute medical conditions. |
| Typical Monthly Cost (Family of 4) | £20 - £50 | £80 - £250+ (highly variable) |
| Core Coverage | Dental, optical, physio, prescriptions. Small cashback amounts. | In-patient/day-patient surgery, cancer care, diagnostic scans, specialist consultations. |
| Financial Scale | Pays out hundreds of pounds per year. | Can pay out tens of thousands of pounds for a single claim. |
| Acute Conditions (e.g., Hernia) | Not Covered. Might offer a small cash benefit if you're hospitalised on the NHS. | Covered. Pays for the private consultation, scans, and surgical procedure. |
| Chronic Conditions (e.g., Diabetes) | Not Covered. | Not Covered. Management remains with the NHS. |
| Pre-existing Conditions | Usually Irrelevant. You can still claim for dental/optical regardless of other conditions. | Excluded. Not covered, typically for a set period (moratorium) or forever (full medical underwriting). |
| Claims Process | You pay first, then claim the cash back. | Insurer pays the hospital/specialist directly (after you pay any excess). |
| Best For... | Families who want help with predictable annual costs and want to encourage regular check-ups. | Families who want to avoid long NHS waits for diagnosis and surgery and ensure fast access to high-quality care. |
Real-Life Scenarios: Putting It All into Perspective
Let's see how these plans would work for a fictional family, the Wilsons (two adults in their early 40s, two children aged 8 and 12).
Scenario 1: Routine Year The Wilsons have a good year with no major health scares.
-
Illustrative estimate: Everyone has a dental check-up and clean (£240 total).
-
Illustrative estimate: Mrs Wilson needs new glasses (£180).
-
Illustrative estimate: Their son twists his ankle playing football and needs four physio sessions (£200 total).
-
Illustrative estimate: Total Out-of-Pocket Cost: £620
-
With a Health Cash Plan (£25/month) (illustrative): They claim back £240 for dental, £180 for optical, and £200 for physio. They get £620 back, covering their entire spend. The plan cost them £300 for the year, saving them a net £320.
-
With Full PMI (£150/month) (illustrative): None of these routine costs are covered. The plan is there for if something more serious happens. They get £0 back for these expenses.
Scenario 2: A Surgical Need Mr Wilson develops severe hip pain. His GP refers him to an orthopaedic specialist. The NHS waiting list for this appointment is 40 weeks.
- With a Health Cash Plan: The plan is of little help. It might cover a small portion of an initial private consultation fee (e.g., £250 of a £300 bill), but it will not cover the MRI scan (
£800) or the hip replacement surgery (£14,000). Mr Wilson remains on the NHS list. - With Full PMI: This is where PMI excels.
- He calls the insurer and gets authorisation for a private specialist. He's seen in 5 days.
- The specialist recommends an MRI, which is done 2 days later.
- Surgery is scheduled for 3 weeks' time in a private hospital.
- The insurer pays for everything directly, minus Mr Wilson's policy excess (e.g., £250). He is back at work months, or even years, sooner than via the NHS route.
Can You Have Both? The Ultimate Family Health Strategy
For families who can afford it, the most comprehensive strategy is to have both a health cash plan and a full PMI policy.
- The Health Cash Plan acts as a budgeting tool, managing all the predictable annual costs and encouraging proactive health maintenance.
- The Full PMI policy acts as a powerful safety net, ready to kick in for the serious, unexpected, and expensive health issues.
This combination provides 360-degree support, ensuring small costs don't sting and large health problems don't lead to debilitating waits. A specialist broker like WeCovr can help you find cost-effective options for both, ensuring they complement each other perfectly.
Decoding the Costs: What Drives Your Premium?
Understanding what you're paying for is essential.
Health Cash Plan Costs are simple:
- The price is determined by the level of cover. A higher level means higher annual claim limits, which costs more.
- Age is not usually a major factor, and prices are often fixed for all ages.
Full PMI Costs are more complex and personal:
- Age: The single biggest factor. Premiums increase as you get older.
- Location: Treatment in central London is more expensive than in other parts of the UK, so postcode affects the price.
- Excess (illustrative): This is the amount you agree to pay towards a claim (e.g., the first £250). A higher excess lowers your premium.
- Hospital List: Policies offer different tiers of hospitals. A list excluding expensive central London hospitals will be cheaper.
- Underwriting:
- Moratorium: The most common type. Pre-existing conditions from the last 5 years are excluded. However, if you go 2 full years on the policy without any symptoms, treatment, or advice for that condition, it may become eligible for cover.
- Full Medical Underwriting (FMU): You declare your full medical history. The insurer then lists specific, permanent exclusions. It takes longer but provides absolute clarity from day one.
- Level of Cover: Do you want full outpatient cover (for all tests and consultations) or just cover for major surgery? Limiting outpatient cover is a key way to manage costs.

Common Mistakes Families Make When Choosing
- Thinking a Cash Plan Covers Surgery: This is the most dangerous misconception. A cash plan will never cover the cost of a private operation.
- Ignoring the Fine Print on PMI: Not understanding what's excluded (chronic/pre-existing conditions) is a common cause of frustration at the point of claim.
- Choosing the Cheapest PMI Without Advice: A cheap policy might have a very limited hospital list or a huge excess, making it less useful when you actually need it.
- Not Reviewing Annually: Your family's needs change, and so does the market. Reviewing your cover annually with a broker ensures you always have the right protection at the best price.
Final Verdict: Which is Best for Your Family?
The right choice depends entirely on your priorities and budget.
-
Choose a Health Cash Plan if: Your main concern is managing the predictable, annual costs of dental, optical, and physio. You have a tight budget (e.g., £20-£40/month) and are happy to rely on the NHS for any serious medical treatment. It’s a smart budgeting tool.
-
Choose Full Health Insurance (PMI) if: Your primary goal is to bypass long NHS waiting lists for diagnosis and surgery. You want the peace of mind that comes from knowing you can access fast, high-quality private treatment for new medical issues. You have a larger budget (e.g., £80-£250+/month) to invest in your family's health security.
Ultimately, these two products serve completely different needs. One is for budgeting, the other is for crisis management. By understanding this crucial distinction, you can confidently choose the protection that gives your family the most security and peace of mind.
