Sorry your husband is ill and your are having trouble finding a place for him, Optomistic. I typed Manchester into the search engine at
https://www.alzheimers.org.uk/find-support-near-you and it only comes up with Accrington which is a few miles away as I recall. You could try the national dementia helpline at
https://www.alzheimers.org.uk/get-support/national-dementia-helpline
If they can't help then the carers support centres may be useful, you will find a local one at
http://carers.org. AgeUK offer advice and services, so try
https://www.ageuk.org.uk/manchester/
I hope any of that is of use, and you find a place where your husband will get the support he needs.
