From a decision of a Costs Judge in a High Court matter parties may, if permission is granted, bring an appeal to a High Court Judge with a further appeal to the Court of Appeal.

The route of an appeal from a decision of a Costs Judge in a County Court matter depends upon whether the Costs Judge heard the matter whilst sitting as a Judge of the County Court. If he or she did so, the parties may, if permission is granted, bring an appeal to a Circuit Judge in the County Court with a further appeal to the Court of Appeal.

In London County Court cases, which are not transferred to the SCCO so as to become High Court cases, the appeal from a Costs Judge lies, if permission is granted, to the London Designated Civil Judge, sitting at the Central London County Court (or such judge as he or she shall nominate).
