Tax credits and DS summer job. Will it be affected?

[Cocopogo]

DS is 16 and looking for a summer job before starting college. I receive working tax credits, single parent, full time job etc.
Will him earning affect my tax credits/child benefit etc?

I believe it's calculated on household income so I would imagine so unfortunately

No they won’t take his income into account as long as it’s definitely tax credits and not UC.
As long as he’s in education (so just a part time job during the holidays)

I think, remembering a few years back with my DS, they can work for 24 hours a week around school with no problem. They never asked his hourly rate, but at that age it as going to be pretty low.
