Royal Mail has issued a new warning about mail delays affecting several postcode areas across the UK. The disruption comes less than a week after services were suspended for the Spring Bank Holiday, when no deliveries or collections took place.
The affected areas include parts of London, Nottingham, Leamington Spa, South Wales, and other locations. Royal Mail said the delays are linked to local operational issues rather than problems across its wider transport network.
Royal Mail normally delivers and collects mail six days a week. According to the company, services did not operate on Monday, May 25, because of the Spring Bank Holiday, before resuming the following day. As of June 1, a number of delivery offices continue to experience service disruption.
The company said some local offices are facing challenges such as high levels of sick absence, staffing pressures, and other local factors. Royal Mail stated that deliveries may be rotated in those areas to reduce delays for individual customers while support is provided to restore normal service.
Local Delivery Offices Affected by the Latest Disruption
According to Royal Mail, the delivery offices currently affected are Carterton (OX18), Leamington Spa (CV31, CV32, CV33), Northolt (UB5, UB6), Northwood (HA6), Nottingham City (NG1, NG3), Pontyclun (CF72), Portslade (BN41, BN42), Syston (LE7), and Tipton (DY4).
The company said it aims to deliver to all addresses where mail is available six days a week. Where local difficulties prevent that from happening, deliveries may be staggered temporarily.
Royal Mail also emphasized that its national transport infrastructure has continued to operate normally. According to the company, both its air and road networks ran to schedule during the previous 24 hours despite the local disruptions.
In a statement, Royal Mail said: “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.”
The company apologized for the inconvenience and thanked customers for their understanding while efforts continue to address the affected areas.
Royal Mail Seeks Improvements After Missing Delivery Targets
The latest disruption comes against the backdrop of wider scrutiny over delivery performance. According to the reports, Royal Mail was fined £21 million by communications regulator Ofcom in October after failing to meet postal delivery targets during the 2024–2025 period.
The company delivered 77% of First Class mail on time and 92.5% of Second Class mail on time during that period, falling short of regulatory requirements.
Royal Mail has since outlined targets aimed at improving performance. The company said it intends to raise First Class next-day delivery performance to around 85% within nine months before reaching Ofcom’s 90% target within a year.
For Second Class mail, Royal Mail said it aims to deliver 93% of letters within three days over a nine-month period and achieve the regulator’s 95% target by May next year.
According to Royal Mail, performance had already improved by March, with 81.1% of First Class mail being delivered within one working day and 90.2% of Second Class mail arriving within three working days.
Chief operating officer Jamie Stephenson said the company is investing in reliability improvements and rolling out a new delivery model nationwide. He added that Royal Mail plans to deploy the model across all delivery offices before the Christmas peak period, while continuing to work toward its delivery performance targets.
