Phone 0845 850 1166 and ask for form HC1, or visit nhsbsa.nhs.uk
You can also get form HC1 from your local Jobcentre Plus or NHS hospital. You may be able to get one from your doctor, dentist or optician.
If you’ve already paid the healthcare costs, you can claim a refund using form HC5 if you apply within three months. You must have the relevant receipt (such as form FP57 for prescriptions). For more information, see the Department of Health leaflet HC11 Help with health costs at nhs.uk/healthcosts
