Hi everyone,
I'm back to work in 2weeks and I will be working 20hrs per week I was just wondering is there any benefits I can apply for?
I know you can use the benefit calculators but I can't find all the information I need to use them atm x

I was just thinking and if I'll be working 20hrs per week would it be working tax credits I would get instead of benefits from the social? x
