Business health insurance has some of the highest advertiser competition of any commercial insurance line in the UK, a signal of just how much insurers are fighting for this business. Here's what it actually costs, and why.
Business health insurance, or business private medical insurance (PMI), is cover an employer pays for so staff can access private treatment instead of waiting on NHS lists. It's grown from a large-corporate perk into something SMEs increasingly offer to compete for talent.
Why it matters for recruitment: 63% of UK workers in 2026 surveys rated health cover as a top-3 workplace benefit, second only to flexible working hours. With growing strain on the NHS, many employees now view private medical insurance as a priority when choosing an employer, not a nice-to-have.
| Tier | Typical monthly cost | What's included |
|---|---|---|
| Basic (inpatient-only) | £30 to £50 | Surgery, hospital stays |
| Mid-tier | £45 to £75 | Adds outpatient consultations, diagnostics |
| Comprehensive | £85 and up | Wider hospital list, mental health, more |
| Director-only schemes | £85 to £150 | No group-size discount applies |
Costs rise with age, a team in their 50s can cost more than double what the same size team in their 20s would cost to insure. Premiums also typically rise 8-15% at renewal from a combination of age inflation, medical cost inflation, and loss of new-business discount.
Employer-paid PMI is a taxable Benefit in Kind. That means:
Despite the BIK treatment, most employers still find it worthwhile, the productivity and retention value tends to outweigh the modest personal tax cost to the employee.
If full PMI isn't affordable yet, a health cash plan reimburses everyday costs, dental, optical, physiotherapy, at a much lower premium, typically £5 to £25 per employee per month. It's a genuine stepping stone rather than a lesser substitute, many growing businesses start here and upgrade to full PMI later.
Most insurers will write a group scheme starting from a single employee, and director-only cover is common. Very small schemes are priced closer to individual policies, so a two-person business pays a higher per-head rate than a thirty-person one, cover is still readily available either way.
The biggest drivers of staff absence in UK SMEs are mental health, musculoskeletal issues, and NHS diagnostic waiting times, all three are areas where fast access to private treatment makes a measurable difference. Self-referral physiotherapy alone, skipping the GP and booking directly, can shorten a single absence significantly, in many cases enough on its own to offset a meaningful share of the policy's annual cost.
