Switching from ESA-IR to Pension Credit

Have couple with one partner on ESA-IR (support group). The other partner (retired) has hit pension credit age. They are getting the pensioner premium with the ESA, but they have capital of nearly £12k, so are being deducted tarrif income.

The tarrif income deductions would be much lower under pension credit. Is there anything to prevent the ESA claim being withdrawn and a claim by the older partner being made for pension credit?

not yet! - get the PC claim in now before UC hits (if the computer ever works)

UC software working? Think we should have a sweepstake based on the year it starts. And a side bet on it never starting (“Labour govt blame lost years of coalition waste, blah, blah, blah”)
