Small business health insurance, from one employee up
Small business health insurance is private medical insurance (PMI) a small company provides for its staff.
Some insurers publish business plans starting from one or two employees.
This guide shows the team sizes they publish, what a quote depends on, how brokers fit in, and how HMRC taxes it.
Every claim here is our summary of a named external source, linked beside it. Sources change: check the wording at the link before you rely on it.

What is small business health insurance?
Small business health insurance, or small business medical insurance, is medical insurance the employer pays for its staff, and sometimes their families (HMRC ↗).
MoneyHelper says the more basic policies usually cover most in-patient treatments and day-case surgery, and some extend to out-patient treatment (MoneyHelper ↗).
Size matters.
Aviva's Solutions plan is for businesses with 1 to 249 employees (Aviva ↗), and Bupa's small business plan for between 2 and 249 (Bupa ↗).
Type your team size to see which published ranges include it.

Small business health insurance for 1 employee
A business of one can find cover: Aviva's Solutions plan starts at 1 employee (Aviva ↗).
A director of a limited company is covered like an employee, and HMRC says a director is chargeable on the premium the company pays (HMRC ↗).
Health insurance for business owners covers the owner's side in more detail.

A policy for yourself
Possible, says Vitality; the premium may not be tax deductible (Vitality ↗).
Small business health insurance quotes: what they depend on
A small business health insurance quote is built from the choices you make, and Aviva lists five ways to reduce the cost of its plan (Aviva ↗).
Underwriting matters too: on Bupa's small business moratorium option you don't fill in a health questionnaire, but a condition you had in the five years before joining isn't eligible for at least the first two years (Bupa ↗).
With full medical underwriting, Aviva explains, you declare your medical history before the policy starts (Aviva ↗).
Bupa offers a quick guide price online, or a complete quote to buy online (Bupa ↗).
- Excess
£50 to £500 at Aviva
A higher excess is one of Aviva's listed ways to reduce cost (Aviva ↗).
- NHS first
Six week option
Aviva lists it (Aviva ↗); MoneyHelper describes cover that only starts when the NHS can't treat within a set time (MoneyHelper ↗).
- Hospitals
Hospital list
Aviva offers reduced hospital lists, or an extended list as an upgrade (Aviva ↗).
- Out-patient
Out-patient limit
Limiting out-patient cover is another of Aviva's listed options (Aviva ↗).
- Family
Partners and children
Bupa: for an additional cost per person (Bupa ↗).
- Underwriting
Moratorium or full
Bupa asks you to choose an underwriting method (Bupa ↗).
Using a small business health insurance broker
You can buy direct or through a small business health insurance broker.
MoneyHelper lists an insurer, a broker, a financial adviser and comparison websites among the places to buy private medical insurance, and points to the AMII website to find a medical insurance broker (MoneyHelper ↗).
We do not recommend brokers or insurers.
The FCA separates information, which is statements of facts or figures, from advice, which is in effect a recommendation (FCA ↗); a broker or adviser can recommend a plan.
Before you use one, the FCA tells consumers to check the firm on its Firm Checker (FCA ↗).

Steps one and two from MoneyHelper (MoneyHelper ↗) and the FCA (FCA ↗); the rest is our checklist, not a recommendation.
How to set up small business health insurance
These are the choices a small business makes, with what insurers and MoneyHelper publish.
This is not a recommendation of a plan or insurer.
For routine costs rather than treatment, a health cash plan is another small business healthcare option: MoneyHelper says cash plans are a common workplace perk that cover routine medical and dental expenses up to a limit (MoneyHelper ↗).
Health cash plans and other PMI alternatives are compared on our employee health insurance guide.
Who
Decide who to cover
Directors only, all staff, or groups with different cover. AXA Health allows up to 6 categories.

Aviva’s core cover includes acute conditions and cancer cover; out-patient cover is an extension on some policies.
Family
Decide on family cover
Bupa offers partners and children for an additional cost per person.

Moratorium or full medical underwriting; AXA Health offers medical history disregarded from 15 employees.
Report
Report it on a P11D
With Class 1A National Insurance on the cost to you.
Steps summarised from AXA Health (AXA Health ↗), Aviva (Aviva ↗), MoneyHelper (MoneyHelper ↗), Bupa (Bupa ↗) and GOV.UK (GOV.UK ↗).
Tax treatment of small business health insurance
Vitality says that for a limited company the premiums are tax deductible, and that the cover is then a taxable benefit in kind for the employees and directors (Vitality ↗).
You report it on form P11D and pay Class 1A National Insurance on the value (GOV.UK ↗).
For your own figures, see GOV.UK's employer guidance or ask your accountant.
- The company
Premiums
Deductible for a limited company, says Vitality (Vitality ↗).
- The employee
Benefit in kind
Chargeable on the premium paid for them (HMRC ↗).
- The employer
P11D and Class 1A
Class 1A at 15% for 2026 to 2027 (GOV.UK ↗), on the cost of providing it (GOV.UK ↗).
- Exempt
Return-to-work treatment
Up to £500 a tax year per employee, if recommended (HMRC ↗).
Small business health insurance vs key person insurance
They do different jobs.
Health insurance pays for an employee's treatment.
Key person cover is owned and paid for by the business and pays the business (Legal & General ↗); HMRC describes it as insuring against loss of profits from the death, critical illness, sickness, accident or injury of a key person (HMRC ↗).
Small business health insurance: UK market data
The ABI says insurers processed a record £2.6 billion of claims for workplace schemes in 2024, a 16% increase on 2023, within a record £4 billion across individual and workplace cover (ABI ↗).
These figures cover all workplace schemes, not small businesses alone.
