If the case was first tried at the Magistrates Court (summary offences or triable-either-way offences where Magistrates have accepted jurisdiction and the defendant has elected trial at the Magistrates Court), the defence can appeal from the Magistrates to the Crown Court against sentence and/or conviction. This is an automatic right and is when the defendant disagrees with the guilty verdict or believes the sentence is too harsh. If the defendant initially pleaded guilty, then an appeal can only be against their sentence.
