Yes I do, Lottie.
Qualification for Pension Credits is based on joint income when couples live together. This means that if one party, who would qualify for the credits if living alone, is penalised because the partner has income which takes the two of them above the limit to qualify. Quite why this should be escapes me. Furthermore, it is strange that joint income is easily assessed for this purpose. However when it was suggested that a fairer way to limit Child Benefit for higher earners would be on joint income it was said to be "too complex".
