Early Pension and legacy benefits

Hello, I received a letter from a company that I worked a few years for 35 years ago regarding the private work pension i was on. I have to submit the pension forms soon by my 60th birthday. I joined their scheme where the pension age is 60. I cannot delay it. It is a small amount 110 pounds or so a month. I could also take a lump sum and have a reduced monthly amount. I have to decide what is best for my circumstance so they tell me. I am currently on ESA in support group and old housing benefit (not lha).

My questions are...

1. will the monthly pension amount i receive be taken as income £ for £ from both my esa and housing benefit, so as an example £110 taken from esa and again from housing benefit making it a £220 deduction. Effectively £110 worse off?

2. If I went for a lump sum option and it put me £500 over £6000 for savings, will £2 (500/250) be taken from esa and again from housing benefit, so £4 in total?

For the future, as we all will be migrating to universal credit - still awaiting letter, will the above answers differ if I were on UC.

Thank you kindly
