Royal Mail Under Fire for Undelivered Letters

Royal Mail Faces Scrutiny Over Undelivered Letters

Royal Mail is facing fresh scrutiny after postal workers across the United Kingdom said they were told to conceal undelivered letters to make performance appear stronger during management visits.

The allegations surfaced as Royal Mail executives are due to speak to Members of Parliament on Tuesday about ongoing delivery delays that have affected millions of customers nationwide.

What Workers Allege, and When it Happens

Ten postal workers, speaking anonymously, described a practice of moving mail into trolleys or other places so it is not visible to senior staff.

They said this was most likely to occur when external managers visited delivery offices, with the undelivered items then brought back into the workflow the next day.

Operational Pressure: Parcels Versus Letters

Workers linked the alleged concealment to pressure to focus on parcel deliveries rather than letters.

They also cited staffing constraints and reduced overtime, saying that high parcel volumes can leave insufficient time to complete letter rounds.

Some workers said they were instructed to “take the mail for a ride” when the volume of parcels made it impossible to deliver all letters that day.

Royal Mail Response and Performance Claims

Royal Mail said the accounts provided by workers do not match its operating procedures.

The company stated that 92% of letters are delivered on time and said it would look into specific allegations where details are provided.

Regulatory Backdrop and Targets Missed

The claims arrive against a backdrop of regulatory action by Ofcom , the UK communications regulator, which has previously fined Royal Mail £37 million for service failures.

Ofcom has also warned that further penalties could follow if performance does not improve.

In the 2024–25 financial year, Royal Mail delivered 77% of first-class mail and 92.5% of second-class mail on time.

Those results were below the company’s targets of 93% for first-class and 98.5% for second-class deliveries.

Labour Issues and What Remains Unclear

The Communication Workers’ Union attributed delivery problems to low pay, poor working conditions, and what it described as a recruitment and retention crisis.

Key details remain unverified in public, including how widespread the alleged concealment is, which sites were involved, and whether it affected reported performance metrics.

With executives set to face MPs, the immediate focus is likely to be whether operational incentives, staffing levels, and oversight are aligned with meeting delivery standards for both parcels and letters.
