For any payment not received by YYY within ten (10) days of its due date, YYY may charge, and you agree to pay, interest (***both before and after judgment*** such interest to be independent of and not merge with the judgment) on overdue payments (from the date due to the date paid by the Customer) initially at a flat rate of £25 for the first 14 days and then at a rate of [XXX]% above the [XXX] base rate prevailing at the time of non-payment.

Neanche il resto della frase mi è chiaro ("such interest to be independent of and not merge with the judgment"). GIA.
