Hi lolau22
I cannot answer your question as it would depend on a number of factors, you say your husband is registered as self employed but lost his work during the pandemic.
The first question to ask; is your husband still registered as self employed?
Second question; does your husband receive Carers Allowance or Carers Element?
I would advise you to seek help from your local welfare rights organisation, You can find your local Welfare Rights Organisation to help you with advice by clicking on the link below and putting in your post code, it will then come up with a MAP with a list of agencies.
