This is not confined to just ED .I live on Peckham Rye SE15 side and have had little post if any since the strikes. My house insurance policy documents never arrived and had new ones sent out ,they took nearly 2 weeks to arrive and I did my car tax on line ,that didnt arrive so had to phone and getting another one sent. Never had a problem before the postal strikes, so much backlog must be a result of this.
