A healthy 30-year-old can pay from around £38/month for mid-level cover, while the UK adult average sits near £80/month. The cheaper policy usually strips outpatient cover, uses a smaller hospital list and carries a higher excess. Both cover the big stuff — surgery and inpatient treatment — but the £90 policy covers the journey to it.
- ✓Cheap policies cut outpatient cover first — consultations and scans before diagnosis.
- ✓The hospital list and excess are the other two big price dials.
- ✓Both tiers usually cover inpatient surgery in full once you're diagnosed.
The three dials that separate £30 from £90
Health insurance pricing looks opaque until you realise almost every gap between two quotes comes from the same three choices. Outpatient cover — consultations, diagnostic scans and tests before you're admitted — is the expensive part, because it's what people actually claim for most often. The hospital list decides whether you can use premium central-London hospitals or a regional network. And the excess is the amount you contribute before the insurer pays.
A £30-ish policy for a young adult typically means limited or no outpatient cover, a standard regional hospital list and a £250–£500 excess. A £90 policy for the same person usually means full outpatient cover, a wider hospital list and a low or nil excess. The underlying promise — private surgery and inpatient treatment when something eligible goes wrong — is broadly the same on both.
What each tier looks like side by side
Here's an illustrative comparison for a healthy adult in their 30s. Real quotes vary by age, postcode and insurer, but the shape holds.
| Budget tier (~£30–£40/mo) | Comprehensive tier (~£80–£90/mo) | |
|---|---|---|
| Inpatient surgery | Covered | Covered |
| Outpatient consultations | Limited (e.g. £500–£1,000/yr) or none | Full cover |
| Diagnostic scans | Often only after admission is agreed | Covered at diagnosis stage |
| Hospital list | Regional / standard network | Wider list, often central London options |
| Excess | £250–£500 | £0–£100 |
| Extras (digital GP, mental health) | Sometimes basic | Usually included or available |
The basic-plan trap
The most common regret we see isn't buying cheap cover — it's not understanding what cheap cover does at claim time. Picture a persistent knee problem. On a comprehensive policy, the consultation, MRI and surgery all run privately from day one. On a stripped-back plan with no outpatient cover, you may need the consultation and scan on the NHS — where diagnostics queues mean roughly 1 in 4 people wait 6+ weeks for tests — before your private cover picks up the surgery itself.
That can still be a rational trade. You've insured the expensive, painful part (an operation costing five figures) and accepted a wait on the cheaper part. But it's a trade you should make knowingly, not discover mid-claim. A middle path many people land on: a capped outpatient allowance of £1,000 or so, which covers a consultation and a scan — enough to get diagnosed privately — without paying for unlimited outpatient care.
The other half of the trap is psychological. Buyers who feel their basic plan 'did nothing' during a claim often cancel at renewal — usually just as they're getting older and cover is getting more valuable. A policy you understand and keep beats a cheaper one you resent and drop. If £30-level cover is what the budget allows, buy it with clear eyes about the outpatient gap, and it will still do its main job: making a five-figure operation someone else's bill.

Which tier should you actually buy?
- Buy the budget tier if your main fear is a long NHS wait for surgery, you could self-fund the odd £200 consultation, and the premium difference matters to your monthly budget.
- Buy the comprehensive tier if you want the whole journey private — GP referral to scan to surgery — and you'd rather pay monthly than face any bill at claim time.
- Either way, get the same quote at multiple tiers before deciding. The gap for your age and postcode may be smaller (or larger) than you expect.

Frequently asked questions
What's the real difference between £30 and £90 health insurance?
Mostly outpatient cover, the hospital list and the excess. A £30-ish policy typically covers inpatient surgery but limits or excludes consultations and scans, uses a regional hospital network and carries a £250–£500 excess. A £90 policy usually covers the full journey from referral to surgery with little or no excess.
Is a £30-a-month health insurance policy worth having?
It can be — it insures the expensive part, private surgery and inpatient treatment, which is what most people fear waiting for. The trade is that diagnosis (consultations, scans) may fall to you or the NHS first. It suits people who could self-fund a £150–£300 consultation but not a five-figure operation.
Does cheap health insurance still cover surgery in full?
Generally yes, minus your excess. Budget-tier policies usually pay eligible inpatient and day-case surgery in full at hospitals on their list — the savings come from cutting outpatient cover and widening the excess, not from capping the surgery itself. Always check the hospital list includes somewhere practical for you.
Why does outpatient cover change the premium so much?
Because it's the most frequently claimed part of any policy. Serious surgery is rare; consultations, scans and physio are common, so insuring them costs more per pound of cover. That's why removing or capping outpatient cover is the single biggest lever between a £30 and a £90 quote.
Can I upgrade from a basic to a comprehensive policy later?
Usually at renewal, yes — but upgrades can involve new underwriting, and conditions that emerged while you held the basic plan may be excluded from the upgraded cover. If you expect to want comprehensive cover eventually, that's an argument for buying closer to it now while you're claim-free.
