These are technical amendments intended to make it clear beyond doubt that regulations can set out the test of low income to be used when people apply for help with National Health Service charges by reference to the calculations relating to income support or housing benefit. This ties the regulations to be made under the new section introduced by clause 13, which will include a means test which will partly cross-refer to calculations made for the purpose of income support and of housing benefit, to the applicable amounts for those purposes. The resources rule for income will refer to the calculations under the regulations for the purposes of income support, but they will specify different figures in some cases. On the requirement side, the income support applicable amounts will be taken. An amount will be added on for net housing costs and then a deduction made in respect of housing benefit actually received.
