Hi Pauls1,
I am not sure about Employment Support Allowance, but online it says - "Is ESA means-tested? The new style ESA is not means-tested. You can claim new style ESA and Universal Credit at the same time – but if you do, your Universal Credit amount will be reduced by the amount of ESA you get"
PIP isn't means tested - Personal Independence Payment (PIP) is extra money to help you with everyday life if you've an illness, disability or mental health condition. You can get it on top of Employment and Support Allowance or other benefits. Your income, savings, and whether you're working or not don't affect your eligibility.
Regards, Chris.
