esa stopped which benefit do I apply for?

Can you please clarify. Has the ESA stopped because your husband has reached pension age (66) or has he been told it will stop when he reaches pension age in the near future.
Who was claiming Carer's Allowance?
How old are you.
Are/were you claiming any other benefits such as Housing Benefit?

By SP I meant his State Pension which you confirmed he will be getting. He should have received a letter informing him to claim this. Does he know how much his State Pension will be?

You receive CA because you care for him and he receives PIP. He will still be receiving PIP and you will still be entitled to CA.

So so he will be getting SP and PIP, you will be getting CA and PIP.

You may be entitled to a small amount of Universal Credit. If so you should both claim this before your husband reaches pension age. However I cannot advise whether there will be any entitlement without knowing how much pension he will get. If he gets the full SP of £175.20 the UC entitlement will be very low. However his SP may be more or less than this amount.

Not until you reach Sate Pension age which for you will be when you reach 67.

You might qualify for new style ESA if you have a health condition that limits your ability to work. It also depends on your past National Insurance record. However if you were awarded ESA you would no longer be paid Carers Allowance because of 'overlapping' benefit rules. However ESA is worth more than CA.

To claim UC you would both need to claim. If you are going to claim UC it is important to do so before your husband reaches 66 because this will mean his Work Capability status is transferred from ESA to UC.
Based on the limited information you have provided I calculate maximum UC entitlement to be
standard £594.04, LCWRA element £341.92 (equivalent to ESA support group), carer element  £162.92 (because you are carer) = maximum UC amount £1,098.88. This assumes you have no children.
From this would be deducted your CA £292/50/month and your husband's SP which, at £118/week, is £511.33/month. This would leave UC payable £295.05/month.
The UC calculation is based on current benefit rates and includes the £87/month temporary increase which may be removed. An announcement is expected on Wednesday as part of the Budget.

If you claimed ESA it would be deducted from the UC payable so there is no financial gain claiming both urless the ESA is worth more than the UC and based on these figures I don't think that is the case.

However I only have limited information. If you have any other income that would reduce the UC payable then ESA could be more advantageous - if you qualified and if you were assessed as being put in the Support Group. However if the difference is slight then being on UC has some advantages because, with no earnings, it gives you access to free prescriptions and dental care which the new style ESA would not.

Just to check - your husband is not expecting any occupational pensions from previous employment?

If you have access to a local advice agency it would be prudent to get a proper benefits check done with someone who can go through your circumstances in detail - but you really need to do this swiftly so that the UC can be claimed before 4th April if that is the right course of action. You will still be able to claim UC at a later date but it would mean that, based on these figures, no UC would be payable for the first three months of the claim.
