The announcement, which highlights potential delays for both letters and parcels, has raised concerns for millions of households relying on timely deliveries during one of the busiest times of the year. While Royal Mail strives to maintain its six-day-a-week delivery promise, it admitted that in several key areas, this will “temporarily not be possible.”
Widespread Delays Across the UK
The warning affects a wide range of postcodes, stretching from Scotland to the southern coast of England. Several local sorting offices have been struggling with high levels of absenteeism due to sickness, staffing issues, and other local factors. To mitigate delays, Royal Mail is rotating delivery rounds and has drafted in extra support to manage the increased volume of mail during the festive period.
Among the impacted areas are major cities like Bristol, Brixton, and Grimsby, as well as rural areas across Wales, Northern Ireland, and Scotland. The full list of affected postcodes includes areas such as:

Royal Mail’s measures to combat these delays include rotating delivery teams, which aims to spread the workload and maintain some level of service across the hardest-hit locations. However, residents in these areas are being urged to expect delays in receiving both letters and parcels.
Regulatory Pressures and Financial Penalties
The warning comes at a particularly challenging time for Royal Mail, which has already been under significant scrutiny from regulators. Earlier this year, the postal service was fined £21 million by Ofcom for failing to meet its delivery targets. According to the regulator, Royal Mail only managed to deliver 77% of first-class mail and 92.5% of second-class mail on time during the 2024/25 financial year, well below its targets of 93% and 98.5%.
The fine marks the third consecutive year that Royal Mail has been penalised for failing to meet delivery standards. Ian Strawhorne, director of enforcement at Ofcom, stated, “Millions of important letters are arriving late, and people aren’t getting what they pay for when they buy a stamp.” This persistent failure has led to mounting pressure for Royal Mail to improve its services, with further fines likely if service levels do not show meaningful improvements in the near future.
Despite these challenges, Royal Mail has promised to keep customers updated on the progress of affected delivery rounds and urged the public to remain patient. The company has also taken steps to address these ongoing issues by recruiting and training additional staff, as well as adjusting its operational processes to better handle seasonal demand.
For many, the Christmas season represents the busiest period for sending cards, gifts, and festive greetings. As delays continue, the impact on consumers is expected to be felt most acutely in the coming weeks, as millions of parcels and letters are set to hit the postal system.
