Welcome to the forum, you might want to have a look at the following FAQ which explain where everything is
Welcome to Benefits and Work Have you confirmed with the DWP that they have the Decision notice from her appeal as I would have expected you to have heard from the DWP by now.
You don't say what the award was? If it was for the Support Group then she should definitely expect to receive some back pay. If it was for the WRAG then it may depend on any time she has previously spent in the WRAG and whether she would be entitled to Income Related ESA or not, but I would still expect some level of back payments in the vast majority of cases.
