A 50-employee company typically pays £35–£110 per employee per month — roughly £21,000–£45,000 a year, with most mixed-age firms landing around £30,000–£40,000. At this size you can usually secure medical history disregarded underwriting (pre-existing conditions covered from day one), corporate-style pricing, and renewals increasingly shaped by your own claims experience.
- ✓Around 50 lives, medical history disregarded terms become the norm — pre-existing conditions covered.
- ✓Budget £30,000–£40,000 a year for a typical mixed-age 50-person scheme.
- ✓Your own claims start driving renewals at this size — scheme management becomes a real job.
What changes at 50 employees
Below about 15 lives, group health insurance is essentially book-rated: the insurer prices your team's ages and postcode against its whole small-scheme portfolio, sets moratorium underwriting, and your own claims barely move the renewal. Somewhere between 20 and 50 lives, all three of those change — and at 50 you're firmly on the corporate side of the line.
- Underwriting upgrades to MHD. Medical history disregarded terms — pre-existing conditions covered from day one, no five-year exclusions — become standard rather than exceptional at this size.
- Pricing becomes negotiable. Fifty lives is a meaningful account. Insurers compete for it, brokers can tender it properly, and multi-benefit deals (adding group life or income protection) attract better terms.
- Claims experience enters the renewal. Your scheme's own claims history starts to be blended into pricing — good years help you, bad years follow you.
- Admin needs a system. Fifty members means monthly joiners and leavers, P11D reporting at scale, and usually integration with whatever HR or benefits platform you run.
The absence maths scales too: at 9.4 sick days per employee per year, a 50-person company loses around 470 days annually — nearly two full-time years — and mental ill health drives 41% of the long-term portion. The NHS is brilliant. The waiting isn't: a 14.1-week orthopaedic median or 9.3-week mental health median, multiplied across 50 people, is a measurable productivity line.
What a 50-employee scheme costs
The per-head range is the standard £35–£110 per employee per month (UK average around £57), but at 50 lives the blend matters more than the range. Most mixed-age companies land at £30,000–£40,000 a year; a young workforce on core cover can run nearer £21,000, and a senior-heavy firm on comprehensive terms with a London hospital list can reach £45,000 or beyond. Insurance premium tax at 12% is included.
| 50-employee scheme shape | Indicative annual cost |
|---|---|
| Young workforce, core cover, capped outpatient | £21,000–£28,000 |
| Mixed ages, mid-range, full diagnostics + mental health | £30,000–£40,000 |
| Tiered: execs comprehensive, managers mid, staff core | £28,000–£38,000 |
| Senior-heavy, comprehensive, extended hospital list | £40,000–£55,000+ |
Tiering is standard at this size — typically three tiers by grade — and an excess of £100–£250 per person trims 10–20% off the premium. Group rates run 10–30% below individual cover throughout. Our business health insurance cost guide details every lever.
MHD underwriting: the big unlock
The single most valuable thing about crossing this size threshold is medical history disregarded (MHD) underwriting. Small schemes run on moratorium terms — conditions from the last five years excluded until two symptom-free years pass. MHD removes all of that: every member's pre-existing conditions are covered from day one, no questionnaires, no exclusions based on history.
For a 50-person company this changes what the benefit is worth. The employees who most value health cover — people managing a heart condition, a previous cancer, a recurring back problem — are exactly the ones moratorium serves worst. MHD makes the benefit real for them, which shows up in recruitment (senior hires with medical history can be promised genuine cover) and in honest benefit communication: 'everything's covered from day one' is a sentence HR can actually say. Our underwriting guide covers the mechanics.
Tender your 50-employee scheme properly
Claims experience: your renewal is now partly yours
At 5 or 10 lives, your renewal moves with the insurer's whole book. At 50, insurers start blending in your scheme's own claims — typically weighting your experience progressively more heavily as lives increase, until large corporates are effectively priced on their own claims alone. Fifty lives sits in the transition zone: a couple of heavy claim years (a cancer pathway, cardiac surgery, several MSK operations) will visibly move your renewal, and a clean year earns genuine leverage.
This makes scheme management a real discipline rather than an annual direct-debit review. Ask your insurer or broker for claims reporting — most provide anonymised claims-fund summaries at this size. Watch the loss ratio, use it in renewal negotiation, and tender the scheme to the market every two to three years: insurers price keenly to win 50-life accounts, and incumbent renewals are rarely the best available terms. A broker earns their keep at this size — see our broker vs direct guide.
Running it: platforms, payroll and the wider benefits stack
Fifty members generates constant movement — joiners, leavers, tier changes at promotion, family additions. Most insurers provide an online scheme portal, and the larger ones integrate directly with benefits platforms, which matters if you run flexible benefits or want employees self-serving their cover details, digital GP access and claims. If you're choosing a benefits platform anyway, check which insurers it integrates with before you pick either.
Tax and payroll shape is unchanged but bigger: premiums generally corporation-tax deductible, benefit-in-kind tax per member on their tier's value — reported via P11D until the April 2027 payrolling change, which is worth planning for now at 50 members — and Class 1A National Insurance at 15%. This is also the size where companies typically build the wider stack: group income protection and group life cover often price attractively when bundled alongside a 50-life PMI scheme.
One structural decision worth revisiting at this size: whole-workforce cover versus tiers-plus-cash-plan. Many 50-person firms run PMI for all, but a PMI-for-40, cash-plan-for-10 split (or the reverse) is entirely workable where roles and budgets vary widely.
Frequently asked questions
How much does health insurance cost for a 50-employee company?
Typically £30,000–£40,000 a year for a mixed-age workforce on mid-range cover — within the standard £35–£110 per employee per month range. Young workforces on core cover can run nearer £21,000; senior-heavy schemes with comprehensive cover can exceed £45,000. Tiering by grade is standard.
Can a 50-employee company get medical history disregarded underwriting?
Usually, yes — around 50 lives is where MHD terms become the norm rather than the exception. Pre-existing conditions are then covered from day one for every member, with no health questionnaires or five-year exclusions. Expect MHD to price above equivalent moratorium terms, since it covers more.
Does a 50-person scheme's claims history affect its renewal?
Yes — this is the size where it starts to matter. Insurers blend your scheme's own claims experience into renewal pricing, weighting it more heavily as lives grow. Heavy claim years push renewals up; clean years give you negotiating leverage. Ask for anonymised claims reporting and use it.
Should a 50-employee company use a broker for health insurance?
At this size, usually yes. Fifty lives is a genuinely contested account: brokers can tender it across insurers, negotiate MHD terms and claims-fund reporting, and typically re-market the scheme every renewal. Broker remuneration is normally commission inside the premium rather than a separate fee.
Can a 50-employee company offer different cover levels to different staff?
Yes — three-tier structures (executives, managers, wider staff) are standard at this size. Tiers must follow objective criteria such as grade or seniority, applied consistently. Each tier prices separately and benefit-in-kind tax follows each employee's actual tier value.
Do all 50 employees have to join the health scheme?
No. Eligibility rules — permanent contracts, probation completed, defined grades — are standard, and some firms cover part of the workforce with PMI and the rest with a cash plan. What insurers require is objective, consistently applied criteria rather than person-by-person selection.
How does health insurance integrate with a benefits platform at 50 employees?
Most major insurers offer scheme portals, and several integrate directly with benefits platforms for self-serve membership, digital GP access and claims tracking. If you run or plan flexible benefits, check insurer-platform compatibility before committing to either side — it saves significant admin at this size.
What does benefit-in-kind tax look like across 50 employees?
Each covered employee pays income tax on their tier's premium value, reported via P11D until the April 2027 payrolling change — worth planning for at this scale. The company pays Class 1A NIC at 15% on the total benefit value, and premiums are generally corporation-tax deductible. This isn't tax advice.
Is 50 employees enough to add group income protection alongside PMI?
Yes — 50 lives prices well for group income protection and group life, and bundling benefits with one insurer or broker often improves overall terms. Many firms build the full stack at this size: PMI for treatment speed, income protection for long absences, life cover for the worst case.
How often should a 50-person company re-tender its health scheme?
Every two to three years, with claims data in hand — plus an annual renewal negotiation in between. Insurers price aggressively to win 50-life accounts, so incumbent renewal terms are rarely the market's best. Switching normally preserves cover continuity, including MHD terms, if handled properly.
