Royal Mail has today said deliveries are operating "as normal" across most of the country - with the exception of 34 offices.
Five out of the 34 delivery offices hit by Covid-relation self isolation, sick absence or resourcing issues are in south east London.
That means delivering to all addresses with mail in the area six days a week is temporarily not possible.
Royal Mail has said in these cases it will "rotate deliveries to minimise the delay to individual customers".
It apologised for the inconvenience and said targeted support is being provided to support the offices to "address their challenges" and restore service to the "high standard customers would normally receive".
The south east London Royal Mail offices most impacted are:
- Camberwell (SE5)
- East Dulwich Delivery Office (SE22)
- Greenwich Delivery Office (SE10)
- Herne Hill Delivery Office (SE24)
- Sydenham Delivery Office (SE26)
The full Royal Mail statement said: "Deliveries are operating as normal across most of the country today.
"We aim to deliver to all addresses we have mail for, six days a week.
"In a small number of local offices this may temporarily not be possible due to local issues such as COVID-related self isolation, high levels of sick absence, resourcing, or other local factors.
"In those cases we will rotate deliveries to minimise the delay to individual customers. We also provide targeted support to those offices to address their challenges and restore our service to the high standard our customers would normally receive.
"We're sorry for any inconvenience and thank you for your understanding.
"We will regularly update customers on the offices most impacted here."
