Statutory interest is not automatically applied. Under Section 69 of the County Courts Act 1984, the court has the discretion to award interest at a rate the court thinks fit or as prescribed, meaning the claimant must explicitly apply for it.

You can download a copy of the judgment by searching on Registry Trust Online to check if the court awarded interest on the original judgment.

If the judgment does not include an interest award, and the bailiff charged you interest, you may reclaim it.

Additionally, if the bailiff charged fees based on a sum that included unauthorised interest, you can apply to the court for a detailed assessment hearing to evaluate those fees together with an applicaiton for your legal expenses.
