Husband got a new job - do I cancel my adults dependant grant

Hi all,

I'm 24+ living with my husband. At the time I applied for SFE he didn't have a job so I received adults dependent grant. He's now got a job and I'm expecting my first payment on the 11th. He's on 50k now. Do I have to let SFE know so they can cancel the grant or no? Will they find out if I don't cancel it? He's only on a 6 month internship so he's on 25k in 6 months, after 6 months he'll have to look for another job so we'll be out of pocket& can't claim universal credit anymore with my student finance and his salary combined. Our rent is extortionate& most of his salary will go to rent

Any help please
