CBESA does not have a savings limit. You can claim CBESA and IBESA at the same time, this then entitles you to free prescriptions and so forth, but then imposes an income and savings limit.
I still not sure wht I’m on ibesa as I wotked full time since leaving school prior to going on cbsa suport group in 2017/2018. After 12 months I was told by letter i could no longer claim cbsa and my claim would stop (which isn’t the case in the suport group?) the day after another letter came through the post saying I was on ibesa (at my tibunal the dwp rep said I should be on cbesa and would sort it) Around 2019 I had to go see a compliabce officer about my savings whitch i told them was an isa towards my pension and the money in the bank is also made up of my daughters dla. I had another letter to visit them again a couple of months later over a purchase and heard nothing ever since. It was the compliance officer who told me what % was cbesa and ibsa.
All very weird. I keep saying I should go onto pip and tell them to stuff the esa as its more trouble than its worth lol.
I get free perscriptions regardless due to my illness, but yes free dentist work.
