If the original judgment is under £600, you can apply for the transfer of the judgment to the High Court to stay (stop) the enforcement because it is in breach of regulations.

Article 8 of the High Court and County Courts Jurisdiction Order 1991, amended by Paragraph 8 of the High Court and County Courts Jurisdiction (Amendment) Order 1999, states that a judgment must be not less than £600 to be transferred up to the High Court for enforcement.

Apply to stop (stay) the execution of the Writ of control, given the legislation mentioned above.
