A private health insurance limit is the most a policy will pay for a particular kind of treatment, usually over a policy year. The common one is an out-patient limit: a sum for consultations, tests and therapies that the policy pays up to and no further. Once it is spent, the rest of that year's bills in that category are yours, whatever excess you chose. A reduced limit on a quote is usually there to make the quote cheaper, and that is the decision behind most searches for a private health insurance limit: whether to accept one, and which benefits it touches.
A broker can put several insurers' limits beside one another for your circumstances and show what each does to the quote. Fill in the form on this page to be put in touch with one that is FCA-authorised; it is free and takes a few minutes. This page is the other half of what a private health insurance excess is: that one is about where the insurer's money starts, this one is about where it stops.
Is there a limit on health insurance?
Almost always, but not a single one. Every clause we hold attaches its limit to a benefit rather than to the policy as a whole: the table of benefits goes line by line, and each line says whether that benefit has no yearly limit, is capped at a sum, is capped at a number of sessions, or is not covered at all. AXA Health's handbook shows the first in a single table row:
"If you're an out-patient Surgery No yearly limit"
— AXA Health, Personal Health membership handbook (October 2024), page 4, read 4 September 2026. The copy we read is hosted by an intermediary rather than on AXA's own site.
That row says out-patient surgery on that plan has no yearly cap. It says nothing about the lines around it, which we have not read, so it is not a statement that AXA's out-patient cover is unlimited. At the other end of the scale is a benefit that is not there at all:
"Freedom Elite offers a range of optional additional benefits. These are: outpatient treatment; alternative therapies; mental health care; and dental, optical and private GP fees. If you are covered for any of these additional benefits, they will be shown on the certificate. If an additional benefit is not shown on the certificate, you do not have that cover even though it is mentioned in this guide."
— Freedom Health Insurance, Freedom Elite Policyholder's Guide to Cover (April 2025), page 10, read 4 September 2026.
So "is there a limit" depends on the benefit and on the policy you hold, and the place to find yours is the certificate and the table of benefits, not the quote summary.
The common kinds of limit, in the insurers' own words
Three shapes come up on the wordings we hold. The first is a money cap on a category of out-patient treatment, running over the policy year. WPA's product information document sets one as standard:
"Out-patient Treatment Consultations with a Specialist – £250 (increase with the Extra Out-patient Consultations Optional Extra)"
— WPA, Complete Health Insurance Product Information Document (November 2025), page 1, read 4 September 2026.
The cap is on a named thing, consultations with a specialist, rather than on out-patient treatment in general, so whether a scan or a blood test draws on it is a question for the full wording. And it is a starting level, not a fixed one: WPA sells an optional extra that raises it. Bupa's guide calls the same idea an "allowance", and shows that not everything you use the policy for draws on it:
"If you have a Direct Access phone or video assessment you won't need to pay an excess for it and the cost won't be subtracted from your outpatient benefit allowance (if either of these apply to your policy)."
— Bupa, Bupa By You policy guide (BINS 14718, 2024), page 7, read 4 September 2026.
An allowance is drawn down by use, "subtracted from" as each bill comes in, and this one service sits outside it. The clause does not say what the allowance is, and we are not inferring a figure. The second shape is a count rather than a sum:
"Out-patient benefits CT, MRI and PET scans, including professional fees where appropriate. Out-patient surgery. Up to three sessions of post-operative physiotherapy."
— The Exeter, Health+ Insurance Product Information Document (October 2025), page 1, read 4 September 2026. An IPID is a regulatory summary, not the full policy, so a limit absent from it is not absent from the policy.
"Up to three sessions" is a limit in visits, not pounds; a fourth session is outside the benefit however little it costs. The third shape is a limit that is really an option, and choosing it does more than lower a ceiling:
"If you have chosen a reduced out-patient limit of £500 or £1,000 you are not covered as an in-patient, day-patient, or out-patient for treatment for: complications of pregnancy and childbirth, or surgical procedures on the teeth performed in a hospital"
— Aviva, Healthier Solutions terms and conditions (April 2025 issue), page 8, read 4 September 2026. The copy we read is hosted in a broker's document library; the terms issued with a policy are the ones that bind.
On this wording the reduced limit is a cap on out-patient spending and also a change to what the policy covers in every setting, in-patient included. The six clauses side by side:
| Clause we hold | What it limits | How the limit is expressed |
|---|---|---|
| WPA, Complete Health IPID, page 1 | Out-patient consultations with a specialist | £250 as standard, raised by an optional extra |
| Bupa, Bupa By You guide, page 7 | An "outpatient benefit allowance", where the policy has one | Drawn down by use; a Direct Access assessment does not draw on it; amount not in this clause |
| Aviva, Healthier Solutions terms, page 8 | Out-patient treatment, where the reduced option is chosen | £500 or £1,000, and two kinds of treatment removed in every setting |
| The Exeter, Health+ IPID, page 1 | Post-operative physiotherapy | Up to three sessions |
| AXA Health, Personal Health handbook, page 4 | Out-patient surgery | "No yearly limit" |
| Freedom, Elite guide, page 10 | Out-patient treatment as a whole | Optional; not held unless shown on the certificate |
These are extracts, one clause each, not a ranking of the insurers. With a quote in front of you, ask for the table of benefits behind the out-patient figure and what the figure counts; a broker can gather that from several insurers in one conversation, and there is no charge for asking.
Why a limit can matter more than an excess
An excess and a limit are both numbers on a quote that leave you paying towards treatment, and they are easy to read as the same kind of thing. They are not. An excess is a first slice: a fixed sum, paid once against the first bill or bills, after which the policy pays. Bupa's guide works it through:
"Helen has some physiotherapy which costs £250. We pay Helen's physiotherapist £150 and we'll let Helen know that she needs to pay the physiotherapist £100 (which is the policy excess). If Helen needs other treatment during the policy year, she doesn't need to pay another excess."
— Bupa, Bupa By You policy guide (BINS 14718, 2024), page 10, read 4 September 2026.
Helen pays £100 once; the policy pays the rest of that bill and the whole of the next ones that year. The excess is finite, and it is spent early.
A limit works from the other end. It is a ceiling on what the insurer pays for a category, and once it is reached the policy stops paying for that category until the policy year renews. Suppose, with figures that are illustrative and not any insurer's, a policy with a £100 excess and a £500 out-patient limit, where two consultations and a scan earlier in the year have already used £450 of the limit. A £250 physiotherapy bill arrives. The policy pays £50 of it; the other £200 is the member's, and so is every out-patient bill after it until renewal. The excess played no part, having gone on the first consultation months before.
Three things follow. An excess caps what you pay on the way in; a limit removes what the insurer pays on the way out, and the second can be the larger sum. Once a limit is reached, no excess level changes anything, which is why a low excess and a low out-patient limit on the same quote do not cancel out. And a limit can change what is covered at all, which an excess never does: the Aviva clause above removes two kinds of treatment as the price of a reduced out-patient limit, while the excess clauses quoted on how much excess should you choose change who pays first, and none of them changes what is covered. At claim time the limit can matter more than the excess, and the questions to ask about one are not just "how much" but "what draws on it" and "what does choosing it take away".
What to check on a quote
The quote shows the level of the out-patient limit. The wording decides the rest, and on the clauses we hold it differs between insurers.
- What draws on it. WPA's cap is on consultations with a specialist; another insurer's may pool consultations, diagnostics and therapies in one allowance. Ask which bills count against the figure.
- The period. A limit that runs per policy year starts again at renewal. We hold no clause on a course of treatment that straddles a renewal date, so ask.
- Per person or per policy. Aviva's excess applies "for each member every policy year" (same terms, page 11), but none of the limit clauses we hold says how a limit is shared on a family policy. Do not assume it follows the excess.
- What sits outside it. Bupa's Direct Access assessment draws on neither the excess nor the allowance. A digital GP service or a helpline may or may not, and the wording says.
- What choosing it removes. On Aviva's wording, two kinds of treatment in every setting. Ask the same of any reduced limit you are offered.
- Whether it can be raised. WPA's starting level can be increased by an optional extra. Whether a limit can be raised mid-term, rather than at purchase or renewal, we have not established for any insurer.
A broker who specialises in medical insurance can set those answers from several insurers beside the way you expect to use the policy, so that the limits are appropriate to it rather than simply the lowest on offer. It costs you nothing to ask.
Common questions
Is there a health insurance income tax limit in the UK?
Not for a policy you buy yourself: UK income tax gives no relief on personal private medical insurance premiums, so there is no cap to reach. The phrase mostly comes from India, where section 80D of the Income-tax Act limits the deduction for health insurance premiums, and nothing like it attaches to a UK policy. Where an employer pays for your cover it is normally a taxable benefit in kind reported on a P11D; that is our understanding rather than tax advice, so confirm it with HMRC or an accountant.
Can a limit be increased?
At the point of buying, yes for the one insurer whose wording we hold on it: WPA's £250 cap on specialist consultations can be raised with its Extra Out-patient Consultations option. Whether any insurer will raise a limit part-way through a policy year we have not established, so if that matters, ask before you buy rather than after.
Does the excess count towards the limit?
None of the clauses we hold says how a bill that is partly excess is counted against an out-patient allowance, and we are not going to guess. Bupa's wording shows the two are tracked separately, since one service touches neither, but that is as far as it goes. Ask the insurer whether the whole bill or only its share of it is subtracted from the allowance.
If the number you are weighing is the out-patient limit on a quote, the next step is to see the table of benefits behind it from more than one insurer. Fill in the form on this page, and an FCA-authorised broker will set out current quotes with each insurer's limits and what they cover.
