Corporate Health Insurance UK

UK corporate health insurance for 50+ employees is typically claims-experience-rated, meaning premium is calculated from your actual claims history plus insurer loadings. Typical £50–£110/employee/month for standard cover, dropping to £35–£60 for young, healthy workforces and rising to £150+ for older executive populations. Bupa, AXA and Aviva dominate the corporate market; salary sacrifice and flex-benefits integration are standard.

Corporate Health Insurance: what the cover actually does

Corporate group PMI diverges from SME cover the moment your scheme crosses the insurer's community-to-experience rating threshold — typically 50 lives, but sometimes 100 or 250 depending on insurer and industry. At that point the insurer uses your own three-year claims-loss ratio to set next year's premium, so pricing rewards low-claims workforces and penalises high-claim ones. A good broker manages the claims narrative at renewal — we don't just accept the insurer's opening number.

The corporate market is also where private medical insurance stops being a standalone product and starts being one line item in a total-reward stack. PMI sits alongside employee assistance programmes (EAP), income protection, life assurance, dental, virtual GP, cash plans, wellness apps and mental health platforms. Modern corporate placements bundle 3–5 of these under a single admin platform — Bupa Halo, AXA Wellbeing Hub, Aviva DigiCare+, Vitality's ecosystem — so HR administers one benefit rather than five.

Design decisions get more interesting at scale. Do you cover partners and dependants? Do you offer flex — employees trade holiday days for cover upgrades? Do you split the workforce into director/manager/staff tiers? Do you run salary sacrifice (saving employer NIC) or gross-up the BIK? These all have material cost consequences at 200+ lives, and we model them explicitly before recommending a scheme design.

Which insurers tend to fit best

Before you buy — broker checklist

• Request 3-year claims data from your incumbent 90 days before renewal.
• Benchmark against at least three leading UK insurers each year.
• Model salary sacrifice vs employer-paid — employer NIC saving can be material at scale.
• Confirm continuous personal medical exclusions (CPME) on switch — protects underwriting for long-tenured staff.
• Check hospital network by employee postcode — corporate 'nationwide' lists still have regional gaps.
• Integrate EAP, virtual GP and wellness into one employee-facing platform to drive usage (=ROI).
• Confirm P11D and Class 1A NIC treatment with payroll for year-end filing.

PremierPMI broker desk notes

• Corporate PMI renewals are almost always negotiable — 2025 opening uplifts of 12–18% have routinely settled at 5–9% with a proper claims-narrative rebuttal and a whole-of-market benchmark on the table.
• For workforces over 250 lives, running a formal tender every 2–3 years pays for itself many times over — we typically move 25–35% of tendered accounts based on service, digital experience and mental health depth rather than raw price.
• The single most under-used lever in corporate PMI is dependant pricing. Insurers price dependant cover very differently — moving a 400-life scheme with heavy dependant take-up between Bupa and AXA has produced £80–£120k annual saving in identical benefits.

Common questions

What's the difference between corporate and small business health insurance?

The dividing line is usually 50 lives — below that you're on community-rated pricing (insurer's whole book), above it you're increasingly on claims-experience-rated pricing (your own history). Corporate schemes also typically bundle EAP, wellness, occupational health and digital GP under one master contract, and offer flex-benefit design options SMEs rarely need.

How does claims-experience-rated pricing work?

Insurers use a formula combining your 3-year loss ratio (claims paid / premium collected), the size of your book, industry loading and general medical inflation. A workforce with 40% loss ratio typically holds renewal to +5%; a 90% loss-ratio year can push renewal past +20% unless benefits are restructured. We provide claims-narrative rebuttals at every corporate renewal.

Can we salary-sacrifice corporate PMI?

Yes — under HMRC's OpRA rules the employee agrees to give up gross salary in exchange for the benefit. This saves the employer Class 1 NIC (15% currently) and can save employees income tax and NIC too. The BIK reporting still applies. Most FTSE-listed corporates use salary sacrifice for at least the family-cover portion of the scheme.

Should we offer PMI to all staff or tier it by grade?

Both are legitimate. Single-tier all-employee schemes are simpler to administer and typically get better pricing per head. Tiered (director/manager/staff) schemes contain cost but require careful eligibility rules to avoid HMRC challenge. We help draft policy wording that reflects the tier design and stands up to HMRC scrutiny.

What EAP and wellness services come bundled?

Standard bundled services in 2026 corporate schemes usually include: 24/7 telephone EAP counselling (6–8 sessions), digital GP video consultations, mental health platform (Kooth, Silvercloud or Onebright), musculoskeletal fast-track physio, second-medical-opinion service, and health-risk assessment. Insurers vary widely on quality and integration — worth a demo before you sign.

How does dependant cover work?

Employees can add their spouse/partner and dependent children (under 18, or 24 if in full-time education). Pricing options: employer-paid, employee-paid via salary sacrifice, or split contribution. Insurers price dependant cover very differently — we always model both extremes at renewal to find the optimal split.

What happens when an employee leaves the company?

They leave the corporate scheme on their departure date. Most insurers offer a 'continuation option' — the ex-employee can take an individual policy with the same insurer, keeping their underwriting (no new medical questions), typically within 60 days of leaving. We always brief HR on this option so it can be included in leaver packs.

How do we handle P11D and BIK reporting at scale?

By 6 July each year the employer files a P11D per employee showing the BIK value of any medical cover received. For salary-sacrifice schemes, HMRC's OpRA rules require the higher of the salary sacrificed and the cash-equivalent value be reported. Most corporate payroll platforms (ADP, Ceridian, Sage) automate this if we provide the annual scheme cost report — which we produce as standard.

Can we integrate PMI with our existing group risk products?

Yes — Aviva, AXA and WTW-brokered schemes commonly bundle PMI with income protection, group life, critical illness and dental under a single insurer relationship. Bundling can produce 5–12% saving vs standalone contracts, plus single-supplier admin. We model both bundled and standalone routes at every corporate placement.

How long does it take to move corporate PMI to a new insurer?

Realistically 8–12 weeks from decision to go-live: 2 weeks tender, 4 weeks negotiation, 2 weeks employee communication, 4 weeks technical migration. We run the entire process, coordinate CPME data transfer between insurers, and communicate to your employees so they see zero service disruption.
