evidence: You qualify for full help if your weekly income is less than or equal to your weekly requirements (a personal allowance to cover your day-to-day living expenses and housing costs), or is greater than your weekly requirements by no more than half the current NHS prescription charges. If your income exceeds your requirements, you may be entitled to partial help. Your certificate will show how much you have to pay towards your health costs. The rules governing who's eligible are broadly the same as those for a means-tested benefit. But the assessment also takes into account council tax and housing costs, so you can get help with health costs even if your income is too high for a means-tested benefit.
