What’s the difference between private medical insurance and a health cash plan?

The main differences between a health insurance policy and a health cash plan are what they cover, how they pay for treatment, and how you access care.

Private medical insurance (PMI) is designed to cover unexpected medical costs such as major surgery, cancer treatment, or tests, scans, and consultations with specialists. Health cash plans, on the other hand, typically cover expected medical costs, such as routine dental appointments, eye tests, and prescriptions.

With health insurance, you pay a monthly premium, and if you need treatment, you’ll make a claim, and your insurer will pay your specialists and private hospital directly up to your policy limits. Conversely, with a health cash plan, you pay your dentist, optician, or physiotherapist, then claim cashback from your health cash plan provider, again, up to the plan’s benefit limits.

The table below shows the common differences between private medical insurance and a health cash plan.

How does private health insurance work?

When buying private medical insurance, you’ll choose between several insurers and customise your policy to fit your needs. Health insurance policies run for a year at a time, meaning you can choose to renew, switch to a different provider, or cancel every 12 months.

In return for a monthly or annual premium, your insurer will agree to pay some or all of your medical expenses if you need private hospital treatment. Importantly, health insurance will only pay for treating acute medical conditions that you can recover from reasonably quickly. Chronic conditions, which by their nature can’t be recovered from and require management over your lifetime, are excluded.

Unlike a health cash plan, with health insurance, you must speak to your insurer and get authorisation for claims before starting treatment. Once approved, they’ll pay any hospital and specialist fees directly, less your chosen excess.

How does a cash plan work?

A health cash plan pays cashback on routine health treatments and check-ups. Health cash plans can also pay a fixed sum if you receive NHS treatment, such as overnight hospital stays. Many providers also offer support services, such as access to private GPs, counselling and health advice online or by telephone.

There are several providers whose health cash plans offer various types of cover. As with private medical insurance, you pay a monthly premium. However, you’ll have to pay for appointments and treatments yourself and then claim money back by sending your cash plan provider a receipt.

What does health insurance cover?

Private medical insurance usually includes core cover for inpatient and day-patient hospital treatment. You can tailor your policy with optional extras such as outpatient consultations and mental health cover. Policies vary, so check what is included.

Here’s a quick run-through of typical inclusions:

Private hospital treatment

Most health insurance policies cover the cost of being treated in a private hospital as an inpatient or day-patient, where you’re admitted for a day or overnight. Insurers also tend to include outpatient surgery in their core products, but outpatient consultations are usually only accessible by taking out optional outpatient cover.

Your private medical insurance will cover your accommodation and treatment costs, including operating theatre costs, surgeon fees, and anaesthesia. It may also cover pre-operative scans and even some complex scans, such as CT, MRI and PET scans, but unless you’ve opted for the optional outpatient cover, you’d need to be diagnosed via the NHS or pay out of your own pocket for private diagnosis before your insurance would kick in.

Cancer treatment

Most policies cover surgery, chemotherapy and radiotherapy, while some include various support services, such as nutritional support and advice on wigs. Cancer Research UK says that nearly 1 in 2 of us will be diagnosed with cancer at some point, so cancer treatment is an essential part of private medical insurance policies. You might also find cover for other treatments, such as reconstructive surgery or stem cell therapy.

Insurance policies vary, so it’s worth checking what’s included as standard. Some insurers let you pay an additional premium to enhance your cancer cover.

Counselling and CBT

Full mental health cover is typically only available if you pay to add it as an optional extra. However, most insurance provides some mental health support. Some insurers run specialist mental health helplines that signpost you to support and treatment.

Many policies include a set number of counselling or CBT sessions, sometimes without a GP referral, but the number of sessions and the referral rules vary between insurers.

Virtual GP services

Most insurers include a digital GP service, with phone or video appointments that are often available 24/7. Some let you book appointments online, while others have an app where you can enter your symptoms and request a callback.

You can use the service for advice, referrals, or private prescriptions. They may not be the right choice for more serious conditions, but they can be great if getting an appointment with your NHS GP has become challenging.

Post-surgery rehabilitation

Standard health insurance policies typically only include rehabilitation treatments such as physiotherapy, osteopathy or chiropractic treatment if you need them after surgery. Your inpatient coverage will often include post-surgical rehabilitation up to a specified number of sessions or financial limit.

You’ll need separate cover for physical therapy and rehabilitation without surgery, which insurance companies usually offer at an additional cost.

Full outpatient treatment (optional extra)

A basic policy may include some outpatient procedures, consultant appointments, or tests. However, if you want your private health insurance to cover a broader range of treatments, you’ll need to add outpatient cover to your policy.

For example, if you have a hip problem, you may eventually need a hip replacement, but your doctor may initially recommend less invasive treatments like steroid injections or physiotherapy. With outpatient cover, you can ask for a GP referral, and your insurance will pay for your initial care. Without it, you’ll have NHS treatment first and can only use your health insurance when you need surgery.

Therapies cover (optional extra)

Therapies cover typically includes physiotherapy, osteopathy and chiropractic treatment. Many insurers now cover physical therapies separately from outpatient cover.

Some policies also cover complementary therapies such as acupuncture, usually within the therapies option, but few pay for treatments such as reiki or aromatherapy.

Extended mental health coverage (optional extra)

Policies can include basic mental health support, such as counselling or CBT sessions, but the benefits and limits vary and may not be enough to resolve more serious conditions.

Extended cover typically includes a broader range of therapies and inpatient, outpatient and day-patient care if needed. It’s ideal if you have a stressful job or want to ensure you can get the best care when necessary.

Optical and dental care (optional extra)

Optional optical and dental cover can help with routine care costs. If you meet the relevant age or medical criteria or receive certain benefits, you can qualify for free NHS dental treatment, eye tests, glasses, and contact lenses. You can learn more about free dental care here and free eye tests here.

Otherwise, you will need to pay for private dental check-ups and eye care. Adding optical and dental coverage to your health insurance can be a cost-effective way to pay for your care. Most policies include regular dental check-ups, routine treatments, and eye care, including check-ups, glasses, and contact lenses if your prescription has changed since your last test.

Coverage varies, so always check the small print.

An extended hospital list (optional extra)

An extended hospital list gives you access to more private hospitals than the standard list. While these lists usually cover hospital stays across the country, they exclude areas where healthcare costs are highest. If you live in London or another major city, you could find that a standard list doesn’t cover your local hospital.

Paying an additional monthly premium gives you access to an extended list of hospitals in cities like Birmingham, Manchester or Glasgow and all the hospitals on the standard list. An extended list with central London is the most expensive as costs are highest in the capital. However, it enables you to receive care close to home if you live in London.

Health insurance exclusions

Health insurance doesn’t cover every medical condition. It pays for care for acute conditions that arise after you take out the policy. If you have a chronic health condition such as asthma, diabetes or high blood pressure that requires long-term monitoring, you’ll need to stick with the NHS.

Some exclusions depend on your medical history. With moratorium underwriting, a condition you had symptoms, advice or treatment for in the five years before buying the policy (three years on some, such as the AXA Health Plan) is excluded for at least the first two years. It can be covered after that if you go two years in a row without symptoms, treatment or advice for it.

Insurers also have standard exclusions. These vary but typically include cosmetic surgery, emergency care and straightforward pregnancy and birth.

What does a health cash plan cover?

A health cash plan pays cashback on your routine healthcare costs and can also pay out if you receive NHS care.

Health cash plans cover the costs of routine healthcare and check-ups, which typically include:

Dental treatment and check-ups
Eye care, including tests and scans
Glasses and contact lenses
Physiotherapy, osteopathy and chiropody
Telephone GP services

You can usually claim cashback for any costs, whether you paid for private or NHS care. Most health cash plans also pay a fixed sum for hospital stays and when you give birth or adopt a child.

Each health cash plan has different levels with increasing financial limits depending on your premium. Some health cash plans pay 100% of your costs, while others pay a fixed percentage. Each health cash plan varies in the treatments it covers, so always check if something is particularly important to you.

Do health cash plans have any exclusions?

Health cash plans treat pre-existing medical conditions in different ways. Some, such as Simplyhealth’s, cover them, while others exclude them for a set time or for good: BHSF, for example, won’t pay hospital claims linked to one in the first two years. So, depending on the plan, you may still be able to claim for a condition you already have, such as a fixed sum for a night in an NHS hospital, where private health insurance wouldn’t cover it.

A cash plan that covers pre-existing conditions can be a great way to reduce routine healthcare costs for people needing regular care.

However, cash plans often have a waiting period before you can claim. A payment for a birth or adoption, for example, isn’t paid in the first ten months with BHSF or the first 12 months with UK Healthcare.

Health insurance vs cash plans: advantages and disadvantages

Whether you choose health insurance or a health cash plan depends on your needs and circumstances. Here are a few of the advantages and disadvantages of each to help you decide.

Benefits of health insurance and cash plans

Medical insurance and cash plans offer some of the same advantages, with cash plans increasingly providing virtual GP services, health helplines and reward schemes. Here are some of the benefits that are unique to each.

Benefits of health insurance

Private medical insurance lets you access high-quality private healthcare more quickly than you’d receive it via the NHS. You’ll usually have a private room, and many policies cover cancer drugs that aren’t yet available on the NHS.

Your insurer will recommend consultants if you ask them to and pay your costs, apart from any excess that applies to your policy.

Benefits of health cash plans

A health cash plan is typically cheaper than insurance and encourages you to look after your health by covering all or most of the cost of your routine health treatments and checks. A cash plan can also cover some NHS prescription costs, compared to private prescription medicines that are often more expensive.

Drawbacks of health insurance and cash plans

With any healthcare cover, you may spend more than you claim. It’s wise to check whether your chosen policy or cash plan will help you save money in other ways, for example, by giving you discounts on your regular healthcare costs or expenses such as holidays or gym membership.

Drawbacks of health insurance

Comprehensive health coverage can be costly, depending on your chosen coverage and other factors such as location and age. If you have several pre-existing conditions, you may face significant policy exclusions and chronic conditions aren’t covered at all.

Drawbacks of health cash plans

If you choose a cash plan, you must arrange your treatment and pay for it upfront. This is ideal if you have the funds and are happy to research appropriate providers, but it’s less so if you’re busy and have limited cash flow.

It’s also worth considering how much you usually pay for care and whether your cash plan will save you money.
