Hi
it depends on the age if your youngest.
if they are 3-5; currently you are required to work 16 hrs x NLW per week 52 weeks per year.
if 5-12, it is 25. After 12 it is 35.
this can be found on the government website.
The changes – if any- haven’t yet been officially announced nor the requirements if the changes take place. Expect it will be clearer from next week or after the new financial year.
