NI paid gaps

Have recently paid some gaps but notice it has not been backdated to August 2023. Do we not receive any payments backdated to commencement of Pension ?

Hi, 
You should get backdated payments of your state pension from the date we received the payment if the payment is received after your state pension age.
If you have not, please contact our helpline or webchat so we can see why that may be.
Please find our contact details below.
