Royal Mail issues delivery disruption alert to 15 UK postcodes today — full list

A delivery disruption alert has been issued by Royal Mail over delays across its network. The postal service has revealed a number of areas across the UK won't receive mail on time. As of Monday, May 11, there are delays impacting 15 postcode areas. These include Daventry, Alfreton and Erskine. 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." Over the past 24 hours, Royal Mail's air and road network has ran to schedule. But, not all mail was processed and despatched to schedule over the weekend from the Truro Mail Centre. The firm said: "Some mail posted in the TR postcode area on Friday for delivery to other parts of the UK on Saturday." The delays come as Royal Mail vowed to meet its letter delivery targets by May 2027 as part of a £500million turnaround. There has been criticism over late deliveries, as the firm was even hit with a fine. Royal Mail was fined £21million by Ofcom in October for missing targets after it delivered just 77% of First Class post and 92.5% of Second Class post on time in 2024-25. Last month, Ofcom lowered the delivery targets for First Class post to be delivered the next day from 93% to 90% and Second Class to be delivered within three days from 98.5% to 95%. To help meet the targets, Royal Mail is planning to axe its Saturday Second Class deliveries and move to alternate weekdays - three days one week, and two days the next. Royal Mail said it will improve First Class Next Day delivery to around 85% within nine months, before reaching the 90% target set by regulator Ofcom within a year. The firm also vowed to deliver 93% of Second Class letters within three days over the course of nine months, and to hit the 95% target by May next year.
