Talking with my Ealing postie, my understanding is that the reduced delivery service is as a result of several factors. (1) The quantity of letter/envelope post is considerably reduced nationwide, so sorting offices are delaying a few days to build up envelope volumes, to make postie rounds worthwhile. (2) Staff numbers are reduced because of corona (ill staff, and those 'self-isolating'). (3) The emphasis is on packet/parcel deliveries, using vans.
