A £10–£15/month cash plan tier typically refunds around £70–£110 a year each for dental and optical, plus £100–£200 for therapies like physio, up to annual caps. Against a cost of £120–£180 a year, someone who uses the dentist, optician and occasional physio anyway can come out ahead. Skip claims, and the plan quietly loses you money — and no cash plan funds private surgery.
- ✓A £12/month plan costs £144/year; entry tiers typically cap dental and optical around £70–£110 each.
- ✓Regular dental, glasses and occasional physio users can claim back more than they pay.
- ✓Cash plans refund everyday costs only — private surgery and cancer care are outside their world.
What £10–£15 a month actually buys
Health cash plans are the opposite of health insurance: instead of covering rare, expensive events, they refund small, predictable ones. The main providers — Simplyhealth, Westfield, Medicash and HSF — sell tiered plans from roughly £10 a month, with each tier setting annual caps per benefit category. Entry tiers under £15 typically look something like this (illustrative of the market, not any single provider's table):
| Benefit category | Typical annual cap on a £10–£15/month tier |
|---|---|
| Dental (check-ups, hygienist, fillings) | £70–£110 |
| Optical (eye tests, glasses, lenses) | £70–£110 |
| Physio / osteo / chiro / acupuncture | £100–£200 |
| Specialist consultation / diagnostic contribution | £100–£200 |
| Smaller extras (chiropody, health screening, prescriptions) | £20–£100 each |
Two features make the maths friendlier than it first looks: most plans refund 100% of costs up to the cap (some pay 50–75% on certain categories), and most accept you without medical underwriting — though pre-existing issues and short qualifying periods for some benefits still apply.
The payback maths, done honestly
Take an illustrative £12/month plan — £144 a year. Here's how three realistic users fare:
- The full user. Two dental check-ups and a hygienist visit (~£90), an eye test and contribution to new glasses (~£100 claimed), three physio sessions after a back tweak (~£135 claimed). Total claimed: ~£325 against £144 paid — clearly ahead, assuming each claim sits within its category cap.
- The middling user. Dental check-ups (~£60) and an eye test (~£25). Total claimed: ~£85 against £144 paid — a £59 loss for the year, paid for convenience and the option value.
- The non-claimer. Signs up, forgets, claims nothing. £144 straight loss. Unclaimed benefits are the cash-plan industry's margin.
Who wins, who loses
The winners are predictable claimers: glasses and contact-lens wearers, families paying for children's dental care (check the plan covers dependants — many under-£15 tiers include children free), people with recurring physio needs, and anyone whose NHS dentist access has collapsed and now pays privately for routine care. The plan effectively gives them a discount on money already committed.
The losers are optimistic non-claimers — people who buy the plan as a vague health safety net. A cash plan is not a safety net: it caps out in the low hundreds per category, and it will not pay for a £12,000–£15,500 hip replacement, cancer treatment or any significant private surgery. If what you actually want is protection from big events and long waits, that's health insurance's job, at a very different price.
Everyday costs sorted — now cover the big stuff
How to choose an under-£15 plan
Compare the categories you'll actually claim, not the longest benefit list. Check the percentage refunded per category, qualifying periods, whether children are included, and how claims are made — app-photo claims paid in days beat postal forms. Benenden Health sits adjacent to this market at a flat ~£15.50/month with a different, discretionary model worth understanding separately. Our best health cash plans guide compares the main providers tier by tier, and employers curious about staff versions should see cash plans for employees.
And revisit the maths yearly. Cash-plan tiers and caps change, your claiming habits change, and a plan that paid for itself when the children needed fillings may quietly stop earning its keep once they've flown. The product is only ever as good as last year's claims.
Frequently asked questions
Is a health cash plan under £15 a month actually worth it?
Only if you already spend on the things it refunds. A £12/month plan costs £144 a year; regular dental check-ups, an eye test, glasses and a few physio sessions can claim back £300+, while a non-claimer loses the full £144. Add up last year's dental, optical and therapy spend — above ~£150, it likely pays.
What do £10–£15 health cash plans pay out for dental and optical?
Entry tiers typically cap dental and optical benefits at around £70–£110 each per year, usually refunding 100% of costs up to the cap (some categories refund 50–75%). Therapies like physio typically carry £100–£200 caps. Exact tables vary by provider — compare the categories you'd genuinely claim.
Who should not buy a cheap health cash plan?
Anyone wanting protection against big health events. Cash plans cap out in the low hundreds per category and never fund private surgery — a hip replacement runs £12,000–£15,500 — or cancer treatment. If long NHS waits for serious treatment are your worry, that's health insurance's job, not a cash plan's.
Is a £10 cash plan better than putting £10 a month into savings?
For predictable costs, usually yes. A £10 tier typically returns more than £120 a year if you actually claim the dental check-ups, eye tests and physio allowances. If you rarely use those services, the savings account wins — a cash plan only beats cash when you use what it pays for.
