Interest rate on child support arrears?

[SadAndTired]

Good morning

If my SA doesn't outline an interest rate for child support arrears, is there a current rate? A standard rate, so to speak? Arrears are significant, over three years and worth asking for interest.

Many thanks.

There is lots of good info here, and a link to calculate interest
