It would depend on what kind of visa your husband has. From VFS Global:
Applicant must at least meet the following criteria in order to be eligible to submit a Schengen visa application:
- holding a valid passport/travel document
- holding a valid UK residence permit. In case applicant holds a short stay visa, a C type visa (see example here), for the UK, then applicant needs to apply for a Schengen visa from his/her residence country.
So if your husband has a residency permit he is free to make an application.
