What is there to additional explain? If you have no income in the 2022-23 tax year then you are entitled to add £2880 to your pension and have it grossed up to £3600, with the extra £720 being free money contributed by the Government.
You do not have to waitThis works for everybody, at any age up to 75, even children.
Just pick up the phone to your pension company and tell them you want to add £2880 to your pension. Give them your debit card details over the phone to make payment and they will reclaim the extra £720 for you. You can ask them all this when on the phone.
Voila!
