Compare business health insurance: the like-for-like guide for 2026
To compare business health insurance properly, every insurer has to quote the same cover: the same excess, hospital list, outpatient limit, cancer cover and underwriting. We do that for you across the market, at no extra cost.
To compare business health insurance properly, you need every insurer to quote the same cover: the same excess, hospital list, outpatient limit, cancer cover and underwriting. Most "cheaper" quotes are cheaper because something has quietly been taken out. Compare like-for-like and you find the real saving, which is often thousands of pounds a year for the same level of cover.
Most UK employers stay with the same insurer for years. Their broker renews the scheme, the premium goes up, and nobody takes it to market. That is the single biggest reason companies overpay for group private medical insurance. This guide shows you exactly how to compare business health insurance in 2026, what to look for in every quote, and how to know you are getting the best deal rather than just a lower number.
Send us your current policy schedule or renewal letter and we will compare it against the major UK insurers on a like-for-like basis. Using a broker costs your business nothing extra, because the commission is already built into the premium you pay.
How to compare business health insurance like-for-like
Business health insurance, also called company health insurance, group private medical insurance, corporate PMI or SME health insurance, gives your team fast access to private healthcare when they need diagnosis or treatment. The problem is that no two insurance policies are built the same way. Each insurer packages core cover, options and limits differently, so a straight price comparison tells you almost nothing.
A proper business health insurance comparison works in four steps:
- Give every insurer the same information. Employee names or member numbers, dates of birth, postcodes, who is covered (employee only, partners, children), the start date and your current insurer.
- Fix the specification. Decide the excess, hospital list, outpatient limit, cancer cover, mental health cover and therapies you want, and ask every insurer to quote exactly that.
- Keep the underwriting the same. If your scheme is on switch terms, medical history disregarded or moratorium, the new quotes must mirror it. Otherwise staff with medical conditions can lose cover.
- Compare the total cost, not the headline premium. Include Insurance Premium Tax at the standard 12% rate, any fees, and the cost of the excess to employees.
Do those four things and you can compare business health insurance quotes with confidence. Skip them and you are comparing apples with oranges, which is exactly how businesses end up with worse cover for a small saving.
The comparison checklist: 12 things that change the price
When we compare health insurance for a business, these are the twelve items we line up side by side across every insurer. If a quote is cheaper, one of these is usually the reason.
| What to compare | Why it matters to the price |
|---|---|
| Annual premium including IPT | The real cash cost to the business |
| Excess (per person, per claim or per year) | A higher excess lowers the premium but moves cost to employees |
| Underwriting basis | Decides whether existing medical conditions are covered |
| Hospital list | Restricted lists are cheaper; central London hospitals cost more |
| Outpatient limit | Unlimited, £1,000, £500 or none changes the premium sharply |
| Diagnostics and scans | MRI, CT and PET scans can sit inside or outside the outpatient limit |
| Cancer cover | Check drugs, radiotherapy and any monetary limits |
| Mental health cover | Ranges from mental health support lines to full inpatient cover |
| Therapies | Physiotherapy and other therapies may be capped by sessions or pounds |
| Six-week NHS option | Can reduce the premium if the NHS can treat within six weeks |
| Family cover | Partners and children add cost; who pays for them matters |
| Renewal terms | How the insurer prices your scheme next year |
Put your current policy in the first column and each new quote alongside it. Any row that is worse than today needs to be explained before you accept the quote. A good insurance broker should be able to tell you, line by line, why their quote is cheaper.
What to send for a proper comparison
To compare UK health insurance quotes accurately, the insurers need a small amount of information. You do not need to chase your employees for medical forms if you are switching an existing scheme. Usually we need:
- Your current policy schedule or certificate, showing the level of cover and underwriting
- Your renewal letter with the new premium, if you have received it
- A member list with dates of birth, postcodes and who covers family members
- Your renewal date, and any hospitals or consultants your team uses regularly
- For larger schemes, your claims history from the current insurer
With that, we can go to the major health insurance providers and ask each one to quote your current cover exactly. You then get a side-by-side comparison showing the premium, the differences in cover, and the options that would reduce the cost further if you want them.
Why a cheaper quote is often not cheaper
Here is an illustrative example of what happens when a business compares quotes on price alone. Insurer B looks £2,500 a year cheaper. But look at what has changed.
| Insurer A | Insurer B | |
|---|---|---|
| Annual premium | £28,000 | £25,500 |
| Excess | £250 | £1,000 |
| Outpatient cover | Unlimited | £500 |
| Hospital list | Broad | Restricted |
| Underwriting | Switch terms | New moratorium |
| Headline saving | – | £2,500 |
Insurer B has not saved you £2,500. It has moved cost onto your employees through the excess, cut the outpatient cover that pays for consultations and scans, restricted where people can be treated, and put everyone on new underwriting. An employee part-way through treatment could find their condition is no longer covered. That is not a saving; it is a downgrade.
A like-for-like comparison flips this around. We ask every insurer to quote your current cover first, then show you separately what you would save by changing the excess, hospital list or outpatient limit. You see the true price of the same cover, and then you decide which trade-offs are worth making.
Figures in this example are illustrative only and are not a quote.
Which health insurance provider is best for small businesses in the UK?
There is no single best business health insurance provider. The right insurer depends on your team's ages, where they live, what they claim for, and what you want the benefit to do. The major UK insurers for business plans are Bupa, AXA Health, Aviva, Vitality and WPA, and each has genuine strengths.
| Insurer | Often suits | What to check |
|---|---|---|
| Bupa | Businesses wanting the best-known brand and broad hospital access | Renewal increases for long-standing schemes |
| AXA Health | Businesses that want modular cover and guided specialist options | Which modules are actually included in the quote |
| Aviva | Cost-conscious businesses happy with a guided hospital list | How the guided list works in your area |
| Vitality | Younger, active teams who will use wellbeing rewards | Whether staff will actually engage with the programme |
| WPA | Businesses wanting flexible, shared-cost options from a not-for-profit insurer | How shared responsibility works on claims |
For a small business owner, the best health insurance provider is simply the one that gives your team the cover they need at the lowest total cost. That can only be found by comparing the leading providers on the same specification.
Is AXA or Bupa better for business health insurance?
Neither is better across the board. Bupa is the largest health insurer in the UK with its own clinics and a wide hospital network. AXA Health is known for flexible, modular business health insurance and guided options that can reduce the premium. For some teams Bupa is cheaper; for others AXA Health, Aviva or Vitality wins. We have seen businesses that stayed with one insurer for years save significantly simply by comparing both, plus the rest of the market.
Underwriting: the part most comparisons get wrong
Underwriting decides how an insurer treats your employees' medical histories and pre-existing medical conditions. It is the most important line in any comparison, and the one most often missed. The main types of medical underwriting are:
Full medical underwriting (FMU)
Each employee declares their medical history and the insurer sets specific exclusions at the start.
Moratorium
No forms, but recent conditions are excluded until the member has gone a set period without symptoms or treatment.
Medical history disregarded (MHD)
Pre-existing conditions are covered. Usually available to larger groups and priced accordingly.
CPME and switch terms
Continued personal medical exclusions are used when you move insurer, so the new insurer carries over the existing underwriting rather than starting again.
When you switch insurer to save money, the new policy must continue your existing terms. If a new insurer wants to underwrite everyone afresh, employees with ongoing conditions can lose cover. Always ask for the quote on a switch basis, and get written confirmation of how ongoing treatment and open claims will be handled.
What pushes health insurance premiums up or down
Understanding what drives health insurance costs helps you compare quotes and negotiate. The main factors are:
- Age profile: premiums rise as your team gets older.
- Location: postcodes near central London hospitals cost more.
- Claims history: for larger corporate health insurance schemes, your claims record affects renewal.
- Medical inflation: the cost of private medical treatment, drugs and diagnostics rises every year across the medical insurance market.
- Level of cover: outpatient limits, hospital lists, therapies and optional extras all move the price.
- Excess and six-week option: both reduce the premium in exchange for employees sharing some cost or using the NHS where waits are short.
Many UK employers accept a renewal increase without asking what caused it. Ask your insurer to break the increase down into medical inflation, age, claims and benefit changes. If the increase cannot be explained, it is time to compare.
Where health insurance fits in your employee benefits package
For many UK employers, private medical insurance is the most valued part of the employee benefits package, alongside pension, group life insurance and income protection. Employee health insurance helps you attract and keep good people, and it gets staff diagnosed and treated faster, which means less time off work.
That is exactly why it pays to review it properly. When the benefit is valued, you do not want to cut it; you want to pay the right price for it. A like-for-like review of your UK PMI scheme protects the cover your team relies on while stopping the business from overpaying year after year.
Many private health insurance providers offer extras such as virtual GP appointments, mental health support lines, physiotherapy without a GP referral and wellbeing apps. These are worth having, but they are also where health plans become hard to compare. One insurer includes a virtual GP as standard; another charges for it as an add-on. When you compare health insurance policies, list the extras separately so you can see what each insurance plan really includes.
If you are also reviewing group life insurance or group income protection, it can make sense to look at the whole benefits package together. Some businesses find that the money saved on their health insurance renewal pays for a benefit they did not have before.
Tax: is business health insurance an allowable business expense?
For most limited companies, the premium for company health insurance is normally treated as an allowable business expense for corporation tax, provided it is paid wholly and exclusively for business purposes. For employees, it is a benefit in kind reported on the P11D, and the business pays Class 1A National Insurance on the value.
That means when you compare private health insurance quotes, the true cost to the business is the premium plus IPT plus employer's National Insurance. A lower premium reduces all three, which is why a well-run comparison saves more than the headline figure suggests. Always check your own position with your accountant.
Direct, comparison site or broker: which gets the best price?
You can go direct to an insurer, use a comparison site, or use an insurance broker. Going direct gets you one price from one insurer. Comparison sites for business health insurance are limited and rarely quote group schemes properly. A whole-of-market health insurance broker compares the leading providers on the same specification, negotiates at renewal, and manages the switch so nobody loses cover.
For most businesses, using a broker costs nothing extra: the insurer pays commission from the premium you would pay anyway. A good broker should always tell you how they are paid and show you exactly how each quote compares with your current cover.
Going direct to one insurer
One brand, one quote, and nobody to question the renewal increase.
Using a broker
The leading insurers priced on your group and your current cover, with no extra cost to the business and support at claim time.
Real results from comparing properly
- A company client saved 26% on its company health insurance renewal after we compared the market like-for-like.
- A business that had been with Bupa for years, whose previous broker had never shopped the scheme, saved around £700 a month once we took it to market.
Neither business cut the cover its employees valued. They simply stopped accepting the renewal without comparing. Results vary by group and insurer, and past results are not a guarantee.
Compare business health insurance: frequently asked questions
How can I compare business health insurance quotes and policies?
Give every insurer the same employee data and the same specification, keep the underwriting identical, and compare the total annual cost including IPT. Ask for a difference report that lists every way each quote differs from your current policy.
What is the best small business health insurance?
The best small business health insurance is the plan that covers what your team actually needs at the lowest total cost. That differs for every business, which is why comparing the major UK insurers matters more than picking a brand.
When should I compare my business health insurance?
Start eight weeks before your renewal date. Renewal terms usually arrive four to six weeks before renewal, which leaves little time to compare and switch properly if you wait.
Can I switch insurer if an employee is having treatment?
Often yes, if the new policy is set up on switch terms that continue your existing underwriting. Always get written confirmation of how ongoing treatment will be handled before you move.
Does health insurance cover mental health?
Most business health insurance covers some mental health support, but the level of mental health cover varies widely. Check outpatient therapy limits and inpatient cover when you compare.
Can employees add their families?
Yes. Partners and children can usually be added, and the cost can be paid by the business or by the employee. Moving family cover to employee-paid is a common way to reduce the scheme cost.
