The answer will depend on the Schengen country where you apply as not all of them have a single definition of what a 'resident' is. However generally you should be fine - the website of the French Consulate General in London says the following:
- Your UK residency must have at least 3 months validity after the intended date of departure from the Schengen area.
- As per the decree 2008-1176 of the 13th of November 2008, the French Consulate, London, is not competent in processing visa applications of people not resident in the UK, i.e. holders of βC-Visitβ visas or of a British visa valid for 6 months or less. People who are not resident in the UK must apply for their Schengen visas at the French Consulate in their country of residence.
Since your wife stays in the UK on a 'resident' visa and her stay lasts for more than 6 months, it should be okay for your family to apply for a Schengen visa from the UK.
