An important factor is that tax relief on charges is available to those who are working. On the other side of the equation, allowance must be made for those whom circumstances prevent from working and who are on social welfare incomes. That is provided through the waiver scheme which managers can implement. It is working well, I have re-emphasised it in the Bill and I do not consider that a mandatory provision would improve it in any way. It is a good scheme and we should have confidence in the people operating it.
