Employee health insurance is increasingly popular in the UK, especially as NHS waiting lists remain high (check the latest NHS England Referral to Treatment data for updates). For employers, offering private medical insurance (PMI) can help attract and retain staff, but the true cost is shaped by a set of factors—many of which are easy to overlook until renewal or a claim dispute arises.
What Drives the Cost of Employee Health Insurance?
There’s no single answer to “how much does it cost?” because premiums depend on:
Workforce age and health profile: Older or less healthy groups usually cost more to insure.
Level of cover: Core inpatient-only plans are cheaper than comprehensive cover including outpatient, mental health, or dental benefits.
Location: London and the South East typically see higher premiums.
Underwriting method: Moratorium underwriting often excludes recent conditions automatically, while full medical underwriting requires a health declaration and may allow tailored terms.
Claims history: High-claim groups may face steeper renewal increases.
Provider and scheme size: Larger schemes or those with more negotiating power may secure better rates, but this is not certain.
Messy Example: The Unexpected Renewal Shock
Imagine a 40-person tech company in Manchester. Their PMI policy started in 2022 at £50 per employee per month, covering inpatient and outpatient care. In 2023, three staff made claims for physiotherapy and mental health support. At renewal, the insurer proposed a 22% premium increase, citing higher-than-average claims and rising treatment costs in the region. The finance manager, expecting a modest rise, was unexpectedly affected. After reviewing the policy, they discovered several exclusions for pre-existing conditions and a cap on outpatient sessions. The company had to decide whether to accept the increase, reduce cover, or shop around—a process that took weeks and required input from HR, their broker, and the staff themselves.
Common Exclusions and Disputes
Most UK employee health insurance policies exclude:
Pre-existing conditions (typically any issue you’ve had symptoms or treatment for in the last five years)
Chronic conditions (long-term, incurable illnesses)
Routine dental and optical care (unless specifically added)
Cosmetic or elective procedures
Disputes often arise over whether a condition is ‘acute’ (short-term, treatable) or ‘chronic’, as insurers usually only cover the former. If your claim is denied, ask for the insurer’s written rationale and refer to the Financial Ombudsman if you believe the decision is unfair.
Tax and Payroll: What’s Changing?
Employer-provided medical insurance is usually a taxable benefit-in-kind (BIK) for employees, unless an exemption applies. This means employees pay tax on the premiums their employer pays. At present, most employers report these benefits via P11D forms. However, HMRC has confirmed that mandatory payrolling of certain benefits, including medical insurance, will be phased in from 6 April 2027. Employers should monitor HMRC guidance for updates and review their payroll processes in advance.
Questions to Ask Your HR, Insurer, or Broker
What exactly is covered and excluded under our policy?
Which underwriting method applies, and how does it affect pre-existing conditions?
How will upcoming payroll changes affect my payslip and tax deductions?
What’s the process for challenging a claim denial?
Can I access a summary of benefits and exclusions in writing?
Practical Steps for Employers and Employees
Audit your policy: Review all documentation for exclusions, limits, and excesses. Keep copies of policy documents and any correspondence about cover or claims.
Prepare for payroll changes: Employers should consult payroll providers and update systems in line with HMRC’s phased approach to payrolling benefits. Employees should check payslips for correct deductions.
Keep evidence: Save all relevant emails, letters, medical notes, and bills. This is vital if you need to challenge a decision or escalate a complaint.
Know your escalation route: If a claim is denied, ask for a written explanation. If unresolved, you can contact the Financial Ombudsman for private medical and dental insurance complaints.
