Most NHS treatment is free, but there can be charges for some things. You may be able to get help with NHS health costs if, for example, you are on a low income.
Further information
For information about what costs may be covered, who may be eligible for support, and how to claim, see the Directgov website.
For general background, including leaflet HC11 which sets out what charges you can get help with, please see also Help with health costs on the NHS Business Services Authority website.
