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.

01 · What it is

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.

  • Bupa logoBupa corporate health insurancefrom 250

The size ranges each insurer publishes for its own product.

Being inside a range is not an offer of cover: the insurer decides.

Three health insurance guides, three questions

This page is for small businesses buying cover.

If your question is one of these, the sibling guide answers it more fully.

Our guides; each carries its own sources.

03 · One employee

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.

  • Aviva

    From 1 employee

    Solutions: for businesses with 1 to 249 employees (Aviva ↗).

  • AXA Health

    Available if you have a business bank account (AXA Health ↗).

  • Bupa

  • Sole trader

    A policy for yourself

    Possible, says Vitality; the premium may not be tax deductible (Vitality ↗).

04 · Quotes

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 ↗).

05 · Brokers

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 ↗).

06 · Setting it up

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.

01

Who

Decide who to cover

Directors only, all staff, or groups with different cover. AXA Health allows up to 6 categories.

02

Level

Choose the level of cover

Aviva’s core cover includes acute conditions and cancer cover; out-patient cover is an extension on some policies.

03

Family

Decide on family cover

Bupa offers partners and children for an additional cost per person.

04

Underwriting

Choose how health is assessed

Moratorium or full medical underwriting; AXA Health offers medical history disregarded from 15 employees.

05

07 · Tax

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 ↗).

08 · Health or business cover

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 ↗).

Questions

Small business health insurance, answered

Some insurers publish plans that start at one.

Aviva’s Solutions plan is for businesses with 1 to 249 employees, and AXA Health says that if you have a business bank account you can get business health insurance with it.

Bupa’s small business plan starts at 2 employees.

Vitality says sole traders can set up a policy just for themselves, but the premium may not be tax deductible. Aviva ↗

Direct from an insurer, or through a broker or financial adviser, says MoneyHelper, which also lists comparison websites.

Bupa offers a quick guide price online, or a complete quote to buy online.

For a fair comparison, give every insurer or broker the same details: who is covered, family, the level of cover, the excess and the underwriting method. MoneyHelper ↗

That is your choice.

MoneyHelper lists brokers among the places you can buy private medical insurance and points to the AMII website to find a medical insurance broker.

Whoever you use, the FCA tells consumers to check the firm on its Firm Checker first. MoneyHelper ↗

There is no single answer, and we do not rank insurers: the FCA treats a recommendation as advice, which an FCA-authorised adviser or broker gives.

What matters is what you compare: the team sizes each insurer accepts, core and out-patient cover, the excess, the hospital list, the underwriting method and family cover. FCA PERG 5.8 ↗

We do not publish prices, and the insurers we checked do not publish small business rates: each plan is quoted.

What you pay for is set by the plan you build, such as who is covered, whether family is included and the level of cover; Aviva lists an excess from £50 to £500, the six week option and reduced hospital lists as ways to reduce the cost.

GOV.UK says the value to report for tax is the cost to you of providing it. Aviva ↗

With some insurers, yes.

Bupa says you can offer cover for employees’ partners or children for an additional cost per person, and AXA Health says family members can be added at any point during the policy.

HMRC says the employee or director is chargeable on family premiums the employer pays. Bupa ↗

Vitality says that for a limited company the premiums are tax deductible and can be offset against profits, and that the cover is then a taxable benefit in kind.

GOV.UK says the employer reports it on a P11D and pays Class 1A National Insurance, at 15% for 2026 to 2027.

Check your own position with your accountant. Vitality ↗

Each insurer sets its own range.

Aviva’s Solutions is for businesses with 1 to 249 employees; Bupa’s small business health insurance is for between 2 and 249 employees; AXA Health says each category of cover on a plan needs at least 3 lead members. Aviva ↗

AXA Health lets you vary cover between groups: up to 6 categories can be included on a plan, and each category needs at least 3 lead members.

Check each insurer’s rules on who can be included; for the employment-law side, take advice. AXA Health ↗
