If you have not received the money which the tribunal has awarded to you, currently the tribunal does not have the power to enforce the award.  However, you can ask your local county court to enforce the judgment. You can get the address of your local county court from the Court Service website at www.courtservice.gov.uk. You should tell the county court that your employer has appealed and what the appeal is about.  The court can order interest to be paid on any late payment

An appeal from an employment tribunal can only be made  on a 'point of law'. In order to do this, the appellant must be able to show that the tribunal misdirected itself on the law, misapplied the law or misunderstood the law applicable to the proceedings before it. An unsuccessful party often expresses a wish to appeal on the basis that they do not like the judgment of the employment tribunal, so it is effectively wanting a second opinion. This is not the function of the EAT, which will not hear witness evidence.  Unless the EAT finds there has been perversity or an error of law, an appeal will not be successful, and might not even be allowed to proceed to an appeal hearing.

The fact that a judgment has been reached by a unanimous decision of the employment tribunal panel does not mean that the decision is necessarily correct, and it could still be the subject of a successful appeal if there is an error of law or it is perverse.  However, a finding that there has been a failure to follow statutory procedure may be more difficult to overturn as it is usually a finding of fact

I hope this helps
