Universal Credit and NHS health costs: the £435 and £935 earnings limits

The rule in one line

Universal Credit on its own does not give free NHS health costs. The NHSBSA states this on its page for GP practices. What counts is your earnings in the assessment period, and the test is applied every time you claim.

The two thresholds

The NHSBSA knowledge base sets out the limits:

• £435 or less in total take-home pay in your last full assessment period, for a standard award.
• £935 or less where the award includes an element for a child, or you have limited capability for work (LCW) or limited capability for work and work-related activity (LCWRA).

If you claim as a couple, the limit applies to your joint take-home pay with your partner. With no earnings at all you qualify.

The figure appears on your Universal Credit statement as "Your total take-home pay for this period". If you had no earnings there is no take-home pay section. The NHSBSA also points to the "Other support you may be able to get" part of the statement, which flags health cost help where the earnings fit.

Which assessment period is tested

The NHSBSA uses an assessment period that has already finished:

• For a prescription, the last full assessment period that ended before the date on the prescription.
• For dental treatment, the full assessment period that ended before the first day of the course of treatment.

Take a claimant whose assessment periods run from the 10th of one month to the 9th of the next. A prescription dated 22 October is tested against the period 10 September to 9 October. Earnings in the period running on 22 October are ignored, whatever they are.

What you get when you qualify

Leaflet HC11 and the NHSBSA knowledge base list full help:

• Free NHS prescriptions, saving £9.90 an item in England.
• Free NHS dental treatment, saving £27.90 to £332.10 a course.
• Free NHS sight tests.
• Vouchers towards glasses or contact lenses, worth £42.40 to £233.56 depending on the lenses.
• Free NHS wigs and fabric supports.
• Refunds of travel costs to NHS treatment on referral.

Dependants aged 19 and under included in the award get the same help. Entitlement stops while a sanction has stopped your Universal Credit payment.

Northern Ireland applies the same £435 and £935 figures for dental, optical and travel help, according to nidirect. Prescriptions are already free in Scotland, Wales and Northern Ireland.

What to tick

1. Check the statement for the right assessment period before you reach the counter. The NHSBSA checker at nhsbsa.nhs.uk/check will do the sum if you enter the figures.
2. On a paper prescription, tick the Universal Credit box on the back and sign. According to the NHSBSA, where a practice is still using an older form without a Universal Credit box, patients who meet the conditions should tick the income-based Jobseeker's Allowance box.
3. On an electronic prescription, tell the pharmacy you are on Universal Credit and within the earnings limit when asked.
4. Keep the statement. The NHSBSA checks claims later and sends an enquiry letter where it cannot confirm entitlement.
5. At the dentist, give the same answer on the FP17PR form, which the NHSBSA says now includes Universal Credit.

When earnings fluctuate

Zero-hours contracts, overtime and self-employment push earnings over and under the limit from month to month. The rule is applied period by period, so entitlement can switch on and off.

The NHSBSA's instruction for anyone unsure, or expecting to become entitled, is to pay up front and claim a refund later. For a prescription, this means asking for form FP57 at the counter, which cannot be issued afterwards. Once the statement for the right period shows earnings under the limit, take the FP57 and the statement to any pharmacy within 3 months. The prescription refund guide covers the HC5 forms for dental and optical refunds.

Someone whose earnings sit above the limit most months has two other options. A 12-month prepayment certificate at £114.50 covers unlimited prescriptions. The NHS Low Income Scheme assesses income against living costs and may give an HC2 or HC3 certificate, which lasts for a fixed period rather than resetting monthly.

Other benefits that qualify

The NHSBSA Low Income Scheme page lists the benefits giving full help without an application: Income Support, income-based Jobseeker's Allowance, income-related Employment and Support Allowance and Pension Credit Guarantee Credit. Dependent children under 20 on those claims are covered. Tax credit payments ended on 5 April 2025 and former recipients moved to Universal Credit now follow the earnings test above.

A benefit not on the list does not qualify on its own. People on other benefits with a low income use the HC1 form.

Mistakes that cost money

Ticking because you are on Universal Credit. The NHSBSA published guidance for practices under the title "help your patients avoid costly mistakes" for this reason. A wrong claim costs five times the charge, up to £100, plus the charge.

Reading the wrong period. The current period does not count until it has ended.

Forgetting the partner's earnings. The limit is tested on joint take-home pay for couples.

Claiming during a sanction. Entitlement pauses while payment is stopped.

Not claiming the refund. People who paid while over the limit and then dipped under it have 3 months to recover each £9.90, and only with an FP57. The penalty charge notice guide explains what happens when the NHSBSA cannot match a claim.

Where the figures come from

The £435 and £935 limits, the assessment period rules for prescriptions and dental treatment, the couples rule, the dependants rule, the sanction rule, the statement wording and the pay-up-front advice are from NHSBSA knowledge base article KA-04018. The statement that Universal Credit does not automatically entitle a patient, the income-based JSA box on older forms and the FP17PR change are from the NHSBSA Universal Credit page for practices. The list of other qualifying benefits and the 5 April 2025 end of tax credits are from the NHSBSA Low Income Scheme page. Knowledge base article KA-26606 gives the penalty formula. The £9.90 charge is from the NHS website and voucher values are from leaflet HC11 (V28), April 2026.
