With NHS waiting times remaining high (check the latest NHS England Referral to Treatment data for up-to-date figures), many UK businesses are turning to private medical insurance (PMI) to support staff. But the cost of group PMI is rising, and employers face complex tax rules and frequent claim disputes. Here’s how to keep costs under control, avoid common pitfalls, and help employees understand what’s covered.

Key Cost Controls for UK Staff Health Insurance

1. Choose the Right Excess

Setting an excess (the amount an employee pays towards a claim) can significantly reduce premiums. For example, increasing the excess from £100 to £250 per claim may cut costs by 10–15%. However, higher excesses can discourage staff from claiming for smaller treatments, so it’s important to balance savings with staff wellbeing.

2. Review Hospital Lists

Most insurers offer different hospital networks. Restricting cover to a local or standard list (rather than a ‘London extended’ or ‘premium’ list) can lower costs. If your workforce is mainly outside major cities, a standard list is often sufficient—just check that key hospitals for your staff are included.

3. Consider the Six-Week NHS Wait Option

Some policies offer a ‘six-week option’: if the NHS can treat an eligible condition within six weeks, the policy won’t pay for private treatment. This can reduce premiums by up to 20%. However, it’s not suitable for all roles—if staff need rapid access for business-critical reasons, weigh the savings against the risk of longer waits.

4. Understand Underwriting Methods

Clarify exclusions and terms in writing before staff sign up. Consider sharing a pre-claims checklist so employees know what to expect.

5. Communicate Clearly with Employees

Many disputes arise from misunderstandings. Staff may not realise that chronic conditions (like diabetes or arthritis) are usually excluded, or that they’ll pay tax on employer-paid premiums. Proactive communication helps avoid confusion and complaints later.

Realistic Example: When Policy Details Matter

Imagine a small tech firm in Manchester. They switch to a PMI policy with a £250 excess, a standard hospital list, and moratorium underwriting. An employee, Sam, develops knee pain and is referred for an MRI. The insurer declines the claim, saying Sam had a similar issue three years ago, so it’s excluded under the moratorium rules. Sam is frustrated, and HR spends hours clarifying the policy and supporting his appeal. This could have been avoided if Sam had received clear information about exclusions and the importance of declaring previous conditions before joining.

Practical Steps for Employers

• Review your current policy: Check the excess, hospital list, six-week option, and underwriting type. Ask your broker or insurer for a breakdown of cost-saving alternatives.

• Clarify exclusions: Request written confirmation of what’s not covered, especially around pre-existing and chronic conditions. Share this with staff.

• Audit tax reporting: With HMRC phasing in mandatory payrolling of medical benefits from 6 April 2027, ensure your payroll and reporting processes are up to date. Employees usually pay tax on employer-paid medical insurance unless an exemption applies.

• Prepare staff communications: Draft a simple explainer for employees. For example: “Your company health insurance is a taxable benefit. You’ll see a monthly tax deduction based on your premium. For details, see the GOV.UK guidance on medical or dental insurance benefits.”

• Keep evidence: Save policy documents, renewal letters, and any insurer correspondence. If a claim is declined, request a written explanation and keep all related emails and medical notes.

Questions to Ask

• HR: What’s our current excess, hospital list, and underwriting method? Are there cheaper alternatives?

• Broker/Insurer: Can you provide a summary of key exclusions and options to lower premiums?

• Doctor: Will my diagnosis be classified as acute or chronic for insurance purposes?

• Payroll: Are we ready for HMRC’s payrolling changes from April 2027?

Handling Disputes and Getting Support

If a claim is denied, ask for a clear written reason. If you disagree, use the insurer’s complaints process. If unresolved, the Financial Ombudsman Service can review disputes, including those about pre-existing conditions or policy exclusions.
