Royal Mail has faced a spate of public complaints from customers who say the postal service failed to deliver or mishandled items ranging from live insects to a groom’s suit, as recent official performance figures show the operator missing regulatory targets.

Between the end of March and June, Royal Mail delivered 75.9% of first-class letters and 89.3% of second-class post on time, according to figures published this month. Ofcom is due to lower formal targets next year — reducing the first-class next‑day target from 93% to 90% and the second‑class three‑day target from 98.5% to 95% —but the company’s current performance remains below either benchmark.

Several individual cases, shared with the media and on social platforms, illustrate the range of incidents prompting customer complaints. In southwest London, resident Julia Stephenson described a dispute that began after her dog bit a postwoman and escalated into months without deliveries and the death of live ladybirds sent to her address. Stephenson said Royal Mail staff later refused to deliver until she erected a large external postbox and that packages of live insects left at the local Putney sorting office were discovered dead when she went to collect them.

Royal Mail said deliveries were suspended after “a postie was bitten by a dog for a second time, requiring hospital treatment,” and that safety of staff is the organisation’s first priority. A spokesperson added the suspension should have been explained more promptly and that deliveries had since resumed after assurances that the dog would be securely contained.

In another case, a London groom-to-be, Alex Kozlowski, said a three-piece suit sent from a tailor to his father in Gloucestershire never arrived ahead of the wedding. Kozlowski said a Post Office worker attached the wrong labels to two packages, causing an Amazon return barcode to be applied to the suit parcel; the clothing later showed as accepted into Amazon’s returns system but Royal Mail tracking provided no update. He said a claim process was slow and his family bought a replacement suit before the wedding.

Royal Mail responded that, when return postage is arranged by a retailer such as Amazon, claims for missing items must be raised through the retailer. The company added that high volumes of returns mean not every item is scanned at each stage and that it was likely the parcel had already been returned to Amazon.

Residents of the tiny hamlet of Essworthy in east Devon reported a different problem: a month-long suspension of deliveries because Royal Mail drivers judged the private access road too dangerous. Val Bennallick, 62, who has multiple sclerosis and lives in the hamlet, told reporters she was not told about the change for more than a month and that residents were asked either to move a postbox elsewhere or travel some 14 miles round trip to collect parcels from a nearby town. Royal Mail said the suspension was due to concerns about the poor quality of the private road and apologised for failing to communicate the change promptly. It said it was reassessing the route and working with residents to find a solution.

There have also been reports of particularly sensitive losses. A woman whose adult son died by suicide said an urn of his ashes sent by first‑class post did not arrive and that Royal Mail told her the remains were posted to the wrong address and that the maximum payout did not apply because the contents had no “intrinsic value.” The company later said it sent a £50 goodwill payment and expressed regret for the loss.

The complaints come amid wider operational and structural change at Royal Mail. Last year International Distribution Services, the postal group that owns Royal Mail, was sold to Czech investor Daniel Kretinsky’s EP Group in a £3.6 billion deal that prompted a government review because of the service’s role in national infrastructure. Management has said the new ownership would focus on customers and staff.

Letter volumes have fallen substantially over two decades, a trend Royal Mail and regulators cite as a driver of necessary service and business changes. Royal Mail said it would recruit more frontline staff to make the network “more reliable and resilient.” Jamie Stephenson, interim chief operating officer, said timely letter deliveries matter to customers and that the company was “taking targeted steps to improve reliability.”

Industry groups and consumers have criticised the increase in stamp prices alongside declining service levels. Amanda Fergusson of the Greeting Cards Association said customers expect better service for the higher price of postage.

Royal Mail’s performance data and customer case files show a variety of issues: operational decisions about safety and route risk, mislabelling and scanning gaps in high-volume returns, and customer-service responses that some complainants described as slow or inadequate. The company says it is addressing those operational challenges while making changes under new ownership, and that it apologises where service has fallen short.

Ofcom will continue to oversee performance standards and next year’s lowered targets for next‑day and three‑day delivery will take effect in April. In the meantime, customers and campaigners say the number and severity of reported failures, and the stories that accompany them, underscore the tensions Royal Mail faces as it balances safety, cost pressures and a changing market for letters and parcels.
