If carers are already visiting, Social Services will be aware of him already, but may not deem him vulnerable enough to need additional support - he may not have been reassessed since he was allocated the carers when he left hospital? I’d find out first if his carers are SS employees or from a care agency, and if they have reported his failure to cope to a social worker. If not, that’s the best route to go down. Press for a reassessment. If he has been reassessed and it’s not thought that he needs additional help, you could try Age UK, who with his agreement can help if his primary problem is loneliness and isolation leading to him not caring for himself, which could be the case. They can also put him in touch with support to pay his bills.
Approaching his GP for help is an extra tier of help if all else fails, but the GP will refer back to Social Services anyway, as they are already involved to some degree, I think going through the carers would be the quickest route initially.
