Personal pension query ESA (contribution)

I just read a post about pensions. I get contribution based ESA. I didn't think savings or other income mattered with this. I was hoping to take out £12000 tax free for desperate house repairs. Will this reduce my ESA?
I have read about a limit of £16,000 in savings. I thought this just referred to income bases ESA.

Hi Horty,

It is only private pension (and sometimes ill health insurance) that has an affect on contributory ESA. It doesn't matter how much capital you have or income from other sources. Don't ask me why pensions are treated differently!
