My response would be to quote Reg 2(1)(a) of the Discretionary Financial Assistance Regualtions 2001 (SI 2001/1167):
[quote:b70091747c]Discretionary housing payments
2. – (1) Subject to paragraphs (2) and (3) and the following regulations, a relevant authority may make payments by way of financial assistance (“discretionary housing payments”) to persons who –
(a) are entitled to housing benefit or council tax benefit or to both; [/quote:b70091747c]
and say that no DHP could be awarded.
