Company health insurance is often promoted as a way to show employees they’re valued, offering faster access to treatment than the NHS and a sense of security. But the reality can be more nuanced, especially when staff encounter exclusions, tax surprises, or disputes over what’s actually covered. Understanding both the strengths and the limits of private medical insurance (PMI) is crucial for employees and employers alike.
Why Company Health Insurance Matters
With NHS waiting lists in England reaching 7.6 million as of early 2024 (see NHS England Referral to Treatment data for the latest figures), it’s no surprise that demand for company health insurance has soared. PMI can offer:
Faster access to consultations, diagnostics, and treatment
Choice of hospital and, sometimes, consultant
Support for mental health and therapies
Employee trust—the sense that their employer cares about their wellbeing
However, the promise can feel thin if a claim is declined, or if employees discover their condition isn’t covered after all.
Where the Promise Feels Thin: A Messy Example
Consider this: Sam, a project manager, had company PMI through a well-known provider. When he needed knee surgery, he was told his policy excluded pre-existing conditions. Sam had declared a minor knee injury on his application, but didn’t realise this could exclude any future knee problems. After weeks of back-and-forth, his claim was denied. HR were sympathetic but unsure how to help, and Sam was left waiting for NHS treatment, feeling let down by both his insurer and employer.
Common Disputes and Ambiguities
Pre-existing condition exclusions—often misunderstood and a leading cause of claim denials
Moratorium vs. full medical underwriting—uncertainty over what’s covered, and when
Chronic vs. acute conditions—disputes over whether ongoing conditions (like asthma or diabetes) are included
Tax surprises—especially with changing benefit-in-kind (BIK) reporting requirements
Cause of Denial | Estimated % of Disputed Claims | Key Providers |
|---|---|---|
Pre-existing condition exclusion | 41% | Bupa, AXA Health, Aviva, Vitality |
Chronic vs. acute dispute | 26% | All major providers |
Policy wording ambiguity | 19% | All major providers |
Eligibility/employee status | 14% | All major providers |

Tax and Reporting: What’s Changing?
Employer-provided medical insurance is a taxable benefit-in-kind (BIK). Unless an exemption applies, employees usually pay tax on the premiums their employer pays. HMRC is phasing in mandatory payrolling of certain benefits, including medical insurance, from 6 April 2027. This means:
Employers will need to register for payrolling BIKs by early 2027 (see HMRC guidance)
Employees’ PMI benefit will be taxed via PAYE, affecting tax codes and take-home pay
P11Ds will no longer be used for these benefits once payrolling is mandatory
Period | Employer Action | Employee Impact |
|---|---|---|
2024-25 | P11D or voluntary payrolling | Tax via tax code (if P11D used) |
2025-26 | Prepare for payrolling, register if needed | Monitor for tax code changes |
2027 onwards | Mandatory payrolling | Taxed monthly via PAYE |

Practical Steps for Employees
Ask HR how your PMI benefit is currently reported—P11D or payroll?
Check your payslip and tax code for any changes
Request written confirmation of any changes to your benefit
If unsure, consult HMRC’s guidance on employer expenses and benefits
What to Do if a Claim Is Denied
If your claim is turned down, don’t panic. Here’s a practical approach:
Request a written explanation from your insurer, including the specific policy wording and any medical evidence used
Ask for a copy of your underwriting information (what you disclosed at application)
Check the insurer’s appeals process—all major providers (Bupa, AXA Health, Aviva, Vitality, WPA) must provide this
Keep all correspondence—letters, emails, screenshots, medical notes, and bills
If unresolved after 8 weeks, consider contacting the Financial Ombudsman for help with disputes over exclusions or claims
Questions to Ask HR, Insurer, Broker, or Doctor
Which underwriting method was used—moratorium or full medical?
How does the policy define acute vs. chronic conditions?
What is the process for appealing a denied claim?
Are there any exemptions to the tax treatment of my benefit?
What evidence do I need to support my claim or appeal?
Sample Appeal Email
Dear [Provider],
I am writing to request a full explanation for the denial of my claim (reference: [claim number]). Please provide the relevant policy wording and any medical reports used in your decision. I would also like details of your complaints and appeals process.
Regards,
[Name]
