Will moving in with a partner affect this years 23/24 student loan and grant?

Hi,
I am a mature student with 3 children and have been living independently for over 10 years. I currently receive the full tuition fee loan and maintenance loan from student finance England plus the additional special support loan/grant element as well as the child care grant. If I allow my boyfriend who has a good job and income (around £40,000per year) to move in after Christmas, will my student finance change for this academic year 23/24 and how will this affect my child care grant ect? Also, how do I report this change if it happens?
