Savings/Pension limit?

I all -

I read within this site that there is a limit on the amount of savings you're allowed to have if you claim ESA. It read £16'000. Is this correct? At present my dad already claims ESA with Support Group inclusion, and DLA.

He has received a letter from an old work place offering a lump some on a seemingly forgotten pension, but he's scared to accept. Although if a lump some is accepted it wouldn't be much, I just said I'd message to get a better picture of what is allowed and what isn't to help put his mind at rest and to gain a better understanding to make an informed decision.

His ESA will naturally end on retirement anyway, and I don't think DLA is means tested.

I'd appreciate any advice you're able to offer.
