Your dog is matted. You can continue working it out at home with cornstarch and a slicker brush/comb/undercoat rake, or you can take her to a professional groomer who will be able to get that matted undercoat out in a few hours. Is she a longhair or a shorthair? If she is a longhair, and the guard coat is tangled up, the worst parts may have to be shaved off. If she's a shorthair, my bet is that all that dead undercoat will slide right out and she'll look like a new dog. Make sure the groomer has a high velocity or force dryer. Not sure what prices are like in the UK but I charge anywhere from $55-85 for GSDs with this issue.
