widow at 67

my mum has just become a widow at the age of 67, her husband was 89. she was already receiving a small reduction in her housing benefit and i have contacted them. i have also contacted the council tax dept for her 25% as lone person living in property. she receives state pension already. her husband has left enough to bury himself and give small sums to family..... is there anything else i have forgot, that she may be able to apply for?
