Royal Mail has issued an update on its service across the UK, warning of delays to hundreds of postcode areas. The postal company has named 141 locations across the UK, 23 of which are in Wales, experiencing the most significant disruption.
As of Wednesday, July 22, impacted areas include Barry, Brecon, Penarth and Carmarthen.
Royal Mail statement
Royal Mail said: "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 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."
Network performance
During the past 24 hours, Royal Mail's air and road network has run according to plan. All mail centres have likewise confirmed that the post was processed and dispatched on schedule.
Last year, Royal Mail received a £21 million fine for missing delivery targets. Ofcom imposed the penalty after Royal Mail achieved only 77% on-time delivery for First Class post and 92.5% for Second Class post during 2024 to 2025. The company is aiming to enhance its performance standards this year.
Chief operating officer comments
Jamie Stephenson, Royal Mail's chief operating officer, commented: "We're putting significant investment into improving reliability and reaching these new delivery targets, but delivering lasting change across a network of this scale takes time."
"Universal Service reform is a key part of that, helping us adapt the network to reflect how people send and receive mail today while protecting the one-price-goes-anywhere service for the future."
"We have a plan to deploy the new delivery model to all delivery offices across the country by the Christmas peak period and have set clear targets for each quarter as changes are introduced across the network."
"Early performance this year shows we are tracking in line with the plan and moving in the right direction."
