The payment reference will be the recipient’s National Insurance number followed by DWP COL or HMRC COLS.
For example, if your NI number is JT 83 42 97B, your payment will show up as "JT 83 42 97B DWP COLP" or "JT 83 42 97B HMRC COLP" on your bank statement.
Some households could have to wait for weeks until the cost of living payment is paid.
Payments are starting to be made today but they will continue to be issued until February 22.
Depending on your individual circumstances, some will be paid by HMRC slightly later while others will be paid by the DWP.
For example, those on tax credits only and no other benefits will be paid between February 16 and 22.
To get the final cost of living payment, you will need to have received at least one of seven benefits, including pension credit, between November 13 and December 12.
