Evri and Yodel are the worst parcel firms at helping their customers, while Amazon and DHL are the best performers, according to an Ofcom report.
Although 78% of parcel recipients are satisfied with delivery firms, two-thirds (67%) have had an issue in the past six months, the annual Post Monitoring Report found.
The most common issues were delivery delays (27%), parcels being left in an inappropriate location (23%), the delivery driver not knocking loudly enough (20%), and not being given enough time to answer the door (19%).
Meanwhile, addressed letter volumes fell by 9% to 6.6 billion items in 2023-24, the regulator said.
Ofcom said Royal Mail won back some of the parcel volumes and revenues it lost the previous year because of industrial action.
However, the company continued to make a loss and, while it had made productivity improvements, these were behind expectations, the report found.
Ofcom said: “We continue to have concerns about the longer-term sustainability of the universal service, and we are progressing work on the future of the service, as well as an investigation into Royal Mail’s delivery performance.”
Measured parcels sent by delivery firms across the UK increased by 8.3% to 3.9 billion items in 2023-24, close to the 4 billion pandemic peak in 2020-21, according to the report.
Yodel performed “below average” on some aspects of its customer contact processes, Ofcom found, contributing to a satisfaction score of 38%.
Evri once again achieved the lowest levels of satisfaction, despite improving on its 2023 performance, to 32% during the last year.
Ofcom said it had seen “early signs of improvement” under strengthened regulations to encourage firms to treat customers fairly, with customers having cause to complain about a delayed parcel falling to 19% from 23% last year.
Ofcom said: “We expect further, sustained and continued improvement.
“We remain particularly concerned that disabled consumers and those with limiting conditions are still more likely to encounter difficulties with the delivery process (71%) compared to other people (63%).”
An Evri spokesman said: “We recognise there remains more to do, but Ofcom found that we are making year-on-year improvements and our rising parcel volumes are proof that customers and retail clients are voting with their feet and trust us with their deliveries.
“Evri handles 730 million parcels a year, with 99% successfully delivered on time, and is committed to instilling a culture where every parcel matters. We have invested £32m to develop our customer service options and improve the customer experience at the doorstep.”
