Paid by the month, private health insurance for one adult costs roughly £30 to £60 in your thirties and £250 to £500 in your eighties, as indicative market ranges dated October 2026 rather than quotes. The monthly direct debit is only part of the picture: it buys the cover, while an excess and sometimes a shortfall land on you at claim time, and the policies quoted on this page still run in policy years even when paid monthly. If you are working out what you can afford each month, an FCA-authorised broker can price two or three versions of the same cover side by side. The form on this page arranges that call, free of charge, and your monthly ceiling is the first thing to mention when they ring.
Monthly cost by age: where the market sits
The rows below assume a policy of middling scope: out-patient benefit included, a moderate excess, collected monthly. Each row says who it describes, and none belongs to any named insurer. Treat the row nearest your age as a starting point, not as a figure you will be offered.
| Who is covered | A month, indicative (October 2026) |
|---|---|
| Single person in their thirties | £30 to £60 |
| Single person in their forties | £40 to £80 |
| Single person in their fifties | £60 to £120 |
| Single person at or near 60 | £90 to £180 |
| Single person in their seventies | £150 to £300 |
| Single person in their eighties | £250 to £500 |
| Couple, both in their forties, one shared policy | £80 to £150 |
| Couple, both in their fifties, one shared policy | £120 to £240 |
| Couple, both at or near 60, one shared policy | £180 to £360 |
| Two parents in their thirties or forties plus two children, one shared policy | £100 to £200 |
| Each child added to an existing adult policy | £10 to £25 |
A 53-year-old reads the fifties row and a 74-year-old the seventies row; each sits inside a decade the table names. The table has no row for the mid-sixties, so a 65-year-old should not take a figure from either neighbouring row; cover at 65 looks at that age, and the real number is a quote. The couple and family rows each describe one shared policy, not separate policies stacked up. If you have seen a monthly price well below the lowest row, £12.50 a month for instance, ask what excess, out-patient limit and hospital list sit behind it before setting it against these ranges. The average-cost page explains why ranges stand in for averages, and the per-year page gives the same rows as yearly sums.
Notice how the bottom of each row climbs. The indicative rows rise with each age band, so a monthly premium that feels comfortable at 45 will usually not stay at that level for the same cover, quite apart from other changes at renewal. How premiums move from year to year is covered at why premiums go up.
Five settings that decide what a month costs
Roughly speaking, the more a policy pays and the fewer limits it carries, the higher the monthly figure usually is. Which way each setting nudges the price is general market knowledge; how far is something only a quote shows.
The excess
The excess is the first slice of an eligible claim you pay yourself, and a higher one usually brings the premium down. AXA Health's page for renewing members, How can I control the cost of my plan? (read 21 October 2026), puts it in one line: "Choose your excess. A higher excess will reduce your premium." Raising it means carrying more of each year's bills, so pick a level you could pay on the day. The levels on offer, and how to choose between them, are set out at choosing an excess.
The out-patient limit
Out-patient cover pays for consultations and tests that happen without an overnight stay, and a lower limit, or no out-patient benefit at all, generally lowers the premium. WPA's member page How can I reduce my premium? (read 21 October 2026) says trimming optional benefits and benefit limits can help reduce premiums at renewal, and adds a warning worth weighing as carefully: "With medical treatment costs increasing, reducing your benefits could lead to you having to self-fund part of your claim." Benefit limits explained covers what happens once a limit is reached.
The hospital list
Many policies tie in-patient treatment to a list of hospitals, and a narrower list usually costs less. Aviva's Healthier Solutions terms (the March 2026 edition, AV1590050_GEN6842_0326; check the terms sent with your quote) describe how a list works at page 4: "If you have a hospital list, in-patient and day-patient treatment will be covered when it takes place at a hospital on the chosen hospital list or at a facility within one of our networks." Before you settle on a cheaper list, check which hospitals near you are on it.
The six-week option
Some policies put the NHS first whenever it can treat you quickly, and a version like this usually costs less per month. The same Aviva terms set out their six-week option at page 11: "You cannot claim for private treatment as an in-patient or day-patient, NHS cash benefit, NHS cancer cash benefit or for the cost of an NHS amenity bed if your treatment is available on the NHS (including accident or emergency admissions) within six weeks from the date your specialist recommends it". The line after it rules the option out in the Channel Islands and the Isle of Man. Whether the NHS can see you inside six weeks depends on where you live and what you need, so a lower monthly payment here comes with a real change in when the policy pays.
The underwriting route
Underwriting is how an insurer treats conditions you already have, and it is a choice of route rather than a simple dial. Full medical underwriting and moratorium are two common routes, and each shapes what is covered for conditions that pre-date the policy. Which route will probably cost you less each month, given your own history, is for the broker to talk through with you at no charge.
When you compare quotes, keep the settings identical across them and then change one at a time, so the effect of each shows on the monthly figure.
Paying by monthly direct debit: what each payment buys
Each monthly payment buys a month of cover, yet on several wordings the contract behind it runs for a year. Aviva's March 2026 terms (page 31) put the payment itself simply: "If you pay monthly, each monthly premium payment is for one month’s cover." Saga's Healthplan Super policy book (May 2025, page 31) states: "We offer a choice of monthly, quarterly or annual premiums which can be paid by Direct Debit." The same page calls the policy an annual insurance contract lasting one year. Vitality's Membership Guide (VHTCR0002 08/2024, page 34; a copy hosted by mytribeinsurance.co.uk) lets members pay annually, quarterly or monthly, with each payment matching the period it covers.
Paying monthly is not the same as being free to stop. Freedom's Elite Policyholder's Guide to Cover (footer dated 01/04/2025, page 45) says that once the cooling-off period has passed, "The policyholder must pay a full annual premium although we may allow this to be paid in instalments." On cancelling later in the year it says: "If a claim has been made, we will cancel the policy but we will not refund any premium and the policyholder must pay us the rest of the full annual premium for that period of insurance." Where no claim has been made, the same page says premium already paid for the rest of that period may be refunded. So, on the Saga and Freedom wordings, a monthly premium is not a way to buy cover for a single month; whether any insurer sells shorter cover is taken up on the per-year page.
Paying the year at once can cost less with some insurers. AXA Health's page for renewing members says: "Pay for your plan yearly. We will give you a 5% discount." Freedom's cost page, read on 21 October 2026, describes a 6% reduction for annual payment. Each is one insurer's current offer and says nothing about any other, so the useful step is to see the monthly and the yearly total on the same quote. When the broker calls, ask them to set out each insurer's monthly total, its yearly total and what it does if you stop paying part-way.
What a monthly premium does not pay for
The direct debit buys the cover, not the whole bill. At claim time you still meet the excess, and Aviva's March 2026 terms (page 12) tell members to pay it directly to the specialist or hospital, not to the insurer. At page 13 the same terms explain how a second gap can open: where in-patient or day-patient treatment takes place at a hospital the insurer recognises but which is not on your list, not in one of its networks and not an NHS pay-bed, it pays at most the average cost of equivalent treatment across the hospitals on your list. "This could leave you with a shortfall that the policy does not cover." If the actual cost is below that average, the hospital costs are paid in full.
Where more than one person is on a policy, ask who carries the others' excess. AXA Health's Personal Health membership handbook (October 2024, print code PB116343a/10.24, page 38; a copy hosted by more-health.co.uk) says:
"Consequently, the lead member remains liable for excesses and shortfalls incurred by a family member under the plan."
So the monthly figure and what you pay out can come apart in two places, the excess and any shortfall, and a premium that is low because the limits are low moves more of each bill across to you. For what happens to the payment at the anniversary, see your health insurance renewal price; for how employer-paid cover is generally treated, see the tax page.
Checking a monthly quote before you agree to it
A monthly figure on its own says little. Before accepting one, look for what the price assumes:
- the yearly total beside the monthly payment, and whether paying annually changes it;
- the excess, and whether it applies per person per year or per claim;
- the out-patient limit, or whether out-patient cover is included at all;
- the hospital list, and whether a six-week option is built in;
- the underwriting route shown on the schedule;
- on a shared policy, who is liable for excesses and shortfalls.
Two quotes at the same monthly price can differ on every one of these lines, and the policy wording sent with a quote is the one that counts. If you are weighing treatment prices as well, the private hospital price page deals with cash prices, which are a different number from the cost of cover.
Monthly-premium queries, answered
Is there a quarterly option instead of monthly?
Saga and Vitality, in the documents cited above, both offer quarterly payment alongside monthly and annual. Whether another insurer offers it depends on that insurer and the policy.
When is the first monthly payment taken?
Saga's policy book (page 31) says that where you pay by Direct Debit, the first premium is collected when the policy starts and later ones when they fall due. Aviva's March 2026 terms (page 31) say premiums are collected in advance of their due date. Your own schedule shows the dates.
Can my monthly payment go up part-way through the year?
Aviva's March 2026 terms (page 31) tie a price change to the anniversary only where nothing about the policy changes during the year, and Saga's policy book (page 31) says the new premium is worked out at the start of each policy year. That condition matters: adding someone or changing your cover mid-year falls outside it, so ask how the insurer would price a change before you make one. For the yearly picture, the renewal page explains what happens at the anniversary.
If a monthly payment is missed, is treatment still covered?
Aviva's terms (page 31) say: "We will not pay any claims if premiums are not paid to date at the time your treatment takes place." Saga's policy book (page 31) warns that if a premium is not paid when due it will cancel the policy and not pay for treatment arising after that date.
Your own monthly figure, set beside the yearly one, comes from a quote. Submit the form on this page, then on the return phone call, which costs nothing, tell the FCA-authorised broker which settings matter to you.
