ESA & Universal Credit

Hi I was wondering if anyone can clarify if it's right that you can get a reduction in council tax on standard rate care and mobility ? And how do you apply ?

Hi my husband claimed universal credit back in may after a car accident . Went through all medical stuff and while we was waiting for a decision on what group he would be in . Citizens advice said for him to claim esa as he worked before accident so that’s what we did . Then universal credit came back he was in the non working group . Due to disability he now gets pip enhanced rate for both . But I’m now worried that we will lose the benefits of universal credit as won’t get free prescriptions and glasses etc . Will he be worse of as I believe new style esa is a means tested benefit. And universal credit is . I claim esa have done years and I get pip but only standard rate for both . Will we still get universal credit even on esa and and rent money ? So confused
