Hollie,I do think it would be a good idea if you can get to your local Citizens Advice centre to find out if there are any other benefits you may be entitled to.I don't think there are any but it wouldn't hurt to ask,they may also be able to advise on other help you and your father may be entitled to such as anything that could be done to help your father be more independent at home,maybe widening doorways for wheelchair access and seats for the bath/shower. You haven't said what disability your father has but there is help available for different types of problem from Social Services.
