I am sorry to hear about your ailments. However, it may well be the case you are entitled to more benefits than you are aware. The difficulty is that you require to apply for specific benefits to the DWP and wait for the application etc. However, the best thing to do is drop into your local citizens advice bureau (CAB). They can go through your personal and financial position in detail and enter these details into what is referred to as the QBC system. This system will calculate what benefits you are entitled to and how much. The system will also do the entire calculation without contacting the DWP so no other benefits would be affected in doing this calculation. Furthermore, if you are rejected initially for any such benefits, the CAB can help you with the mandatory reconsider (appeal) of the refusal. If this is still rejected but it is believed you have a claim, the CAB can also provide you with representation should you require to go to a tribunal for the matter.
