What is employer health insurance?
Employer (or group) health insurance is a private medical insurance policy your company holds on behalf of its staff. If you're on the scheme and something new goes wrong, you're referred, diagnosed and treated privately — typically within days — instead of joining an NHS waiting list.
How does a work scheme actually work?
Your employer chooses the insurer, the level of cover, the excess and the hospital list — and pays the premium. You pay tax on it as a benefit in kind: the premium value goes through your tax code, so a £600-a-year benefit costs a basic-rate taxpayer roughly £120 in tax.
When you need it, the flow is the same as a personal policy: GP referral, call the insurer, get authorised, be seen. Many schemes add digital GP appointments, mental health support and physiotherapy on top.
Is health insurance through work enough?
For as long as you're in the job, often yes — it's real cover and it costs you only the benefit-in-kind tax. The gaps are structural:
- It isn't portable. Cover ends when the job does — resignation, redundancy or retirement.
- You don't choose it. Cover level, excess and hospital list are set by your employer, and outpatient limits on core schemes can be tight.
- Family may not be included. Adding a partner and children is sometimes possible, sometimes not, and often at your own cost.
- Later joining costs more. If you leave at 45 and buy your first personal policy, you're priced as a 45-year-old — with 45 years of medical history to underwrite.
Work scheme vs personal policy
| Through work | Personal policy | |
|---|---|---|
| Who pays | Your employer (you pay BIK tax) | You |
| Cover choice | Fixed by employer | Built around you |
| Portability | Ends with the job | Yours for life |
| Family | Sometimes, often at extra cost | Add anyone, priced per person |
| Underwriting | Often generous (MHD on larger schemes) | Based on your history at joining |
| Long-term cost | Free-ish now, expensive to replace later | Cheapest the younger you start |
Leaving your job? Act inside the window
Most insurers let departing employees continue cover personally without fresh underwriting — same conditions covered, new premium at your age. The window is short, typically 30 days from leaving the scheme. If continuation isn't offered or you miss it, an adviser can find the nearest equivalent and tell you honestly what will and won't carry over.
Frequently asked questions
Is health insurance through work a taxable benefit?
Yes. Your employer reports the premium value (currently via P11D) and you pay income tax on it through your tax code. Most people find the benefit still outweighs the tax — but it's worth knowing the number.
What happens to my cover when I leave my job?
It ends — usually on your last day. Most insurers offer a personal continuation option that preserves your underwriting if you act within a set window, typically 30 days. Miss it, and conditions that arose while you were covered may become pre-existing exclusions on a new policy.
Can I add my partner and children to a work scheme?
Often, yes — either funded by your employer or paid by you at the group rate, which is usually cheaper than buying separately. Check what your scheme allows.
Is a work scheme better than a personal policy?
It's cheaper (your employer pays) but it's not yours: you don't choose the cover level, and it ends with the job. A personal policy costs more but is portable, tailored, and priced on the you of today — which matters, because premiums rise with joining age.
My employer offers a low level of cover. Can I top it up?
Sometimes — some schemes let employees upgrade at their own cost. Otherwise, a separate personal policy can sit alongside the work scheme to cover the gaps, such as outpatient limits or hospital lists.
Should I still get personal cover if my job includes health insurance?
If you'd want cover after leaving — and most people would — the honest answer is it depends on your age and health. Joining a personal policy while young and well locks in clean underwriting. An adviser can price both routes in one call.
