Domiciliary care allowance was introduced by way of circular 24/73 and is administered by the health boards on my behalf. The guidelines were modified by way of circular 8/78 and letters of 8 December 1999 and 16 March 2001. DCA is paid in respect of children under 16 years who are severely physically or mentally disabled and who require constant care and supervision at home substantially greater than that which would normally be required by a child of the same age. The current rate of payment is £129.40, 164.30, per month. This rate will increase to 179.80 per month, with effect from 1 January 2002.
