What is Private Medical Insurance?

A guide to providing private medical insurance as a UK employee benefit, covering what PMI covers, the cost, tax and National Insurance treatment, P11D reporting, and how it compares to the NHS.

Private medical insurance (PMI) is an employer-funded benefit that gives employees access to private healthcare for eligible medical conditions. The employer pays the premiums, and the employee can be treated privately rather than waiting for NHS appointments and procedures.

PMI is one of the most popular employee benefits in the UK. According to industry data, around 4 million people have employer-funded PMI, making it a mainstream part of many benefits packages.

Unlike group life insurance, PMI is treated as a taxable benefit in kind and must be reported on the employee’s P11D .

What PMI Covers

Typically Covered

TreatmentDetail
Inpatient treatmentSurgery, hospital stays, specialist procedures
Outpatient treatmentConsultations, diagnostic tests, scans (MRI, CT, ultrasound)
Cancer treatmentChemotherapy, radiotherapy, surgery
Mental healthTherapy sessions, psychiatric consultations (often capped)
PhysiotherapyTreatment following injury or surgery
Day-case surgeryProcedures that do not require an overnight stay

Typically Not Covered

ExclusionReason
Pre-existing conditionsConditions present before the policy starts (unless moratorium period passes)
Chronic conditionsOngoing management of long-term conditions (diabetes management, for example)
GP servicesRoutine GP visits remain with the NHS
Pregnancy and childbirthStandard maternity care (some policies cover complications)
Cosmetic surgeryUnless medically necessary
Dental and opticalUsually separate policies
Emergency treatmentA&E and emergency care remain NHS

PMI is designed for acute conditions – problems that can be diagnosed, treated, and resolved. It is not a replacement for the NHS but a supplement that provides faster access and choice of consultant.

Cost to the Employer

PMI premiums depend on several factors:

FactorImpact
Age of employeesOlder employees cost significantly more
Group sizeLarger groups benefit from better rates
Cover levelComprehensive cover with low excesses costs more
Claims historyHigh claims in previous years increase renewal premiums
Industry and locationLondon and the South East tend to cost more; manual occupations cost more
Family coverExtending cover to spouses and children increases the premium substantially

Indicative Premiums (per person per year)

Age BandBasic CoverComprehensive Cover
20-29£300 - £500£500 - £800
30-39£400 - £700£700 - £1,100
40-49£600 - £1,000£1,000 - £1,600
50-59£900 - £1,500£1,500 - £2,500
60+£1,500 - £2,500£2,500 - £4,000

These are illustrative figures. Actual premiums vary significantly between insurers and depend on the specific scheme design.

Tax Treatment

For the Employer

  • Premiums are an allowable business expense for Corporation Tax
  • The employer pays Class 1A National Insurance at 13.8% on the value of the benefit
  • The NIC liability is calculated on the cost of the premium (not any claims paid)

For the Employee

  • The premium paid by the employer is a taxable benefit in kind
  • It must be reported on the employee’s P11D form
  • The employee pays income tax on the value of the benefit at their marginal rate
  • If the employee is a 20% taxpayer and the annual premium is £800, they pay an additional £160 in income tax
  • If they are a 40% taxpayer, the additional tax is £320

P11D Reporting

The employer must report the cost of PMI on the P11D for each employee who benefits from it. The relevant section is Section I (Private medical treatment or insurance).

P11D RequirementDetail
What to reportThe cost of insurance premiums paid or the cost of medical treatment provided
When to reportBy 6 July following the end of the tax year
NIC dueClass 1A NIC at 13.8%, payable by 22 July (electronic) or 19 July (cheque)

Payrolling Benefits

As an alternative to P11D reporting, employers can payroll the benefit. This means adding the value of the PMI premium to the employee’s taxable pay each month, so tax is collected in real time through PAYE. This eliminates the need for a separate P11D entry for that benefit.

To payroll benefits, the employer must register with HMRC before the start of the tax year.

Scheme Design Options

Excess (Deductible)

An excess is the amount the employee pays towards each claim before the insurer covers the rest:

Excess LevelEffect on PremiumEmployee Pays
Nil excessHighest premiumNothing per claim
£100 excessModerate savingFirst £100 of each claim
£250 excessSignificant savingFirst £250 of each claim
£500+ excessLargest savingFirst £500+ of each claim

Introducing an excess can reduce premiums by 10-30% and discourages minor claims.

Underwriting Basis

MethodHow It WorksBest For
MoratoriumPre-existing conditions are excluded for the first 2 years; after 2 years symptom-free, they are coveredSimple to administer; no medical forms
Full medical underwritingEach employee completes a medical questionnaire; insurer decides exclusionsMore clarity on what is covered from day one
Medical history disregardedAll pre-existing conditions covered from day one (for groups, typically 20+ employees)Larger groups; maximum cover for employees

Who to Cover

OptionTypical Arrangement
Employee onlyMost common; covers the individual employee
Employee plus spouse/partnerExtends cover to a spouse or partner
Employee plus familyCovers the employee, spouse/partner, and dependent children
Directors onlySome small companies provide PMI only to directors

If different levels of cover are provided to different groups of employees (e.g., directors get family cover, other staff get employee-only cover), each level is a separate benefit for P11D purposes and the value reported reflects what each individual receives.

PMI and the NHS

PMI does not replace the NHS. In practice, most PMI policyholders continue to use the NHS for:

  • GP services – PMI requires a GP referral before seeing a specialist in most cases
  • Emergency care – A&E remains the first point of contact for emergencies
  • Prescriptions – routine prescriptions continue through the NHS
  • Maternity care – standard pregnancy and birth care

PMI adds value by providing:

  • Speed – consultations and diagnostics within days rather than weeks or months
  • Choice – the employee chooses their consultant and hospital
  • Comfort – private rooms, flexible appointment times
  • Access to treatments not available on the NHS (in some cases)

Accounting Treatment

Profit and Loss Account

PMI premiums are recorded as a staff cost:

AccountDebit (£)Credit (£)
Employee benefit costs (PMI)12,000
Bank / Creditors12,000

The Class 1A NIC cost is a separate charge:

AccountDebit (£)Credit (£)
Employer NIC costs1,656
HMRC creditor1,656

Year-End Considerations

If the PMI policy renewal date does not align with the company’s financial year end, an accrual or prepayment may be needed to ensure the correct amount of premium is charged to the correct accounting period.

Managing Claims Costs

PMI premiums are heavily influenced by claims experience. Employers can manage costs by:

  • Promoting employee wellbeing – healthy employees make fewer claims
  • Using an employee assistance programme (EAP) for early intervention on mental health and musculoskeletal issues
  • Introducing an excess to discourage minor claims
  • Reviewing the policy annually and comparing quotes from multiple insurers
  • Adjusting cover levels – reducing outpatient limits or adding a hospital list restriction can lower premiums
  • Encouraging NHS use for non-urgent, straightforward conditions

PMI as Part of a Benefits Package

PMI works alongside other protection benefits:

Together, these benefits form a comprehensive protection package that helps attract and retain staff. PMI consistently ranks among the top three most valued benefits in UK employee surveys, alongside pension contributions and flexible working.
