Choosing between a health cash plan and full private medical insurance (PMI) is one of the most important decisions UK employers face when designing their employee benefits package. Both options can improve staff wellbeing, reduce absenteeism, and boost retention — but they serve very different budgets and needs.
Understanding how each type of cover works, what it costs, and who benefits most will help you decide which fits your company’s budget. Let’s break down the key differences so you can make an informed choice for your team, whether you’re based in London, Manchester, Birmingham, or elsewhere in the UK.
What Are Health Cash Plans?
A health cash plan is a simple, low-cost way to help employees manage everyday healthcare expenses. For a fixed monthly premium — often as low as £5–£20 per employee — staff can claim back money for routine treatments like dental check-ups, eye tests, physiotherapy, and even glasses.
Cash plans are not insurance. They do not cover major medical events, hospital stays, or surgery. Instead, they act as a reimbursement scheme, paying set amounts for each treatment. This makes them ideal for covering the small costs that NHS services usually cover but with long waiting times, or for private routine care.
Key features of health cash plans:
- Fixed annual limits per treatment (e.g., £50 for a dental check-up)
- No medical underwriting or health questions
- Quick claims process, often online
- Can include employee assistance programmes and virtual GP services
- No access to private hospitals for surgery or serious conditions
What Is Full Private Medical Insurance (PMI)?
Private medical insurance provides comprehensive cover for acute conditions requiring specialist treatment, diagnostic tests, and hospital stays. Employees can choose to be treated privately, avoiding NHS waiting lists and gaining faster access to consultants.
PMI is typically more expensive than a cash plan — premiums range from around £50 to £150+ per person per month for a standard corporate policy. But the level of cover is far greater, covering cancer treatment, surgery, and inpatient care.
Key features of PMI:
- Cover for inpatient and day-patient treatment
- Outpatient cover for consultations, scans, and tests
- Options for mental health and cancer support
- Medical underwriting or moratorium apply for pre-existing conditions
- Tax implications: PMI premiums are a taxable benefit in kind for employees
Head-to-Head Comparison: Health Cash Plans vs PMI
| Feature | Health Cash Plan | Private Medical Insurance |
|---|---|---|
| Typical monthly cost per employee | £5–£25 | £50–£150+ |
| What it covers | Routine treatments (dental, optical, physio) | Inpatient, day-patient, outpatient, surgery |
| Hospital stays | No | Yes |
| Waiting times | Instant claims | May have exclusions for pre-existing conditions |
| Medical underwriting | None | Yes (moratorium or full) |
| Tax on premiums for employees | Not taxable (unless cash alternative) | Taxable as benefit in kind |
| Best for | Low-cost wellbeing perks | Serious health cover and fast access |
Budget Considerations for UK Employers
Your budget is the biggest deciding factor. If you want to offer a meaningful health benefit for a tight per‑head cost, a health cash plan offers excellent value. For under £200 per year per employee, you can provide cover for dental check-ups, eye tests, and physio — benefits staff actually use.
Full private medical insurance is a bigger investment. However, for businesses with higher budgets, PMI offers the “wow” factor that attracts and retains senior talent. Many employers offer both: a cash plan for all staff and PMI for directors or longer‑serving employees.
Tax treatment matters
- Health cash plan premiums are not a taxable benefit for employees if paid by the employer (benefit is limited to small non‑cash gifts).
- Full PMI premiums are a taxable benefit, and employees pay income tax on the value. This adds a small administration cost but still provides significant value.

Which Option Attracts and Retains Staff?
Staff value different things. A cash plan appeals to those who want help with day-to-day health costs — especially younger employees who rarely need hospital treatment. Full PMI is highly valued by older workers or those with families who want to skip NHS queues.
Combining both in a wellbeing package that includes mental health and fitness benefits can cover all bases.
Real‑Life Examples: How Much Do These Plans Cost?
A London‑based digital agency with 20 employees could pay around £2,400 per year for a basic health cash plan company‑wide. That same group could expect to pay £18,000–£24,000 per year for a standard corporate PMI.
Small business owners in cities like Manchester or Glasgow often start with a cash plan due to budget constraints. As the business grows, they add PMI for key staff.
If you’re self‑employed or a freelancer, a health cash plan might be a more affordable first step. Read our guide for freelancers on UK health insurance.
When to Choose a Health Cash Plan
- Your budget is under £20 per employee per month
- You want a benefit that everyone can use regularly
- You’re a small business with limited headcount
- You want to top up NHS services rather than replace them
- You prefer no medical underwriting and instant claims
When to Choose Full Private Medical Insurance
- You have a higher per‑employee budget (£50+ per month)
- You want to cover serious illness and surgery
- You aim to reduce long‑term sickness absence due to waiting times
- You are a director‑only company looking for comprehensive cover
- You operate in a competitive sector where fast access to healthcare is a key differentiator
Can You Offer Both?
Many large UK employers do exactly that. They provide a health cash plan as a baseline benefit for all employees, then offer PMI as an optional extra or for senior roles. This approach balances cost and coverage, giving staff choice.
For example, a company with 50 employees might spend £10 per head on a cash plan for everyone (£500 per month) and then add PMI for 10 senior staff at £80 each (£800 per month). Total monthly cost: £1,300 — far less than covering all 50 on PMI.
How to Decide: A Step‑by‑Step Process
- Survey your staff — ask what health benefits they value most.
- Check your budget — work out a per‑employee maximum.
- Compare providers — look at cash plan and PMI quotes side by side.
- Consider tax implications — HMRC treats these differently.
- Test a cash plan first — if PMI is too expensive, a cash plan is a low‑cost start.
- Review annually — as your company grows, you can upgrade.

Most importantly, don’t let perfect be the enemy of good. A health cash plan is far better than no health benefit at all. And once you see the positive impact on staff morale and absence, upgrading to PMI may become a natural next step.
