Blow to NHS as Royal Mail raises prices for bulk users by a third
Royal Mail will raise wholesale postal prices by an average 25% from 5 October, hitting bulk customers like the NHS, banks and HMRC with a multimillion-pound bill.
Intelligence analysis by Llama

Royal Mail is raising wholesale postal prices by an average 25% from October, with some access mail tariffs climbing 36%. The move lands hardest on bulk users like the NHS, which spent at least £100m posting letters in 2024, while the postal service itself keeps missing Ofcom delivery targets.
The UK's post office is like the only pizza place in town, and it's raising its bulk-delivery prices by a lot. Because fewer people are sending letters these few years, the cost of keeping all the red vans running has gone up, and the NHS, which sends millions of appointment letters, will have to pay a lot more.
Analysis
The 36% Squeeze on the NHS Mailbag
Royal Mail's wholesale customers are the unseen middlemen of British communication. Firms such as UK Mail, Whistl and Citipost pre-sort and consolidate letters for banks, HMRC, utilities and the NHS, then hand them to Royal Mail for the final-mile delivery that still touches the vast majority of UK post. The new tariff regime lands directly on that pipeline. The headline figure is an average 25% rise, but the access mail business economy service, used for less urgent bulk letters up to 100g, climbs 36.1%, while the access advertising mail tariff for large letters rises 11.4%. The NHS, which previous reports put at more than £100m in postal spending in 2024, is the most politically sensitive casualty. A 25% increase on that kind of base implies several million pounds of new annual cost at a time when the health service is already under acute financial strain, and the Mail Users' Association has called the increase "unprecedented."
A Network Bleeding Volume
Royal Mail frames the increase as a cost-reflective necessity, and the underlying math is genuinely harsh. The company told customers that access mail volumes have tumbled from 6.3bn items a year in 2019-20 to roughly 4.2bn now, a fall of almost a third in less than a decade, even as the number of delivery points has crept up to 32m UK addresses. Fixed collection, sortation and delivery infrastructure spread across thinner volume means the unit cost of every letter rises. Royal Mail also says it has lost almost £800m over the last four years and that its finances sit below the level Ofcom considers compatible with a sustainable universal service. A pricing reset is the most direct lever the company can pull, especially when its regulator has so far allowed the universal service obligation to be met on a loss-making basis.
Křetínský's Balancing Act
The new owner is Czech billionaire Daniel Křetínský, whose EP Group completed its takeover of Royal Mail's parent IDS in April 2025, and the price hike is the clearest signal yet of how he intends to close the financial gap. At the same time, the service is failing the targets the regulator sets. Ofcom has fined Royal Mail £37m since 2023 for missing delivery performance and in June opened a fresh investigation after almost a quarter of first-class mail arrived late in the year to March. The regulator is also examining whistleblower and union claims that letters are being deprioritised in favour of parcels, a charge Royal Mail denies. The company is therefore trying to extract more revenue from fewer letters while simultaneously being told its existing service is substandard, a tension that will define the next phase of UK postal policy and that bulk customers, including the NHS, are now paying to paper over.
Key points
- Royal Mail is raising wholesale postal prices by an average 25% from 5 October, with the access mail economy service up 36.1%.
- The NHS spent at least £100m on posted letters in 2024, so the rise could add several million pounds to its costs.
- Bulk customers including UK Mail, Whistl and Citipost sort mail for big organisations such as banks, HMRC and the NHS.
- Access mail volumes have fallen from 6.3bn items in 2019-20 to about 4.2bn now, against a delivery network of 32m UK addresses.
- Royal Mail has lost almost £800m over four years and has been fined £37m by Ofcom since 2023 for missing delivery targets.
If the higher wholesale tariffs stabilise Royal Mail's finances, the company could invest in the network and rebuild on-time delivery performance, potentially reducing the regulatory fines that have totalled £37m since 2023. A financially healthier Royal Mail would also give Ofcom a stronger foundation on which to enforce service standards.
The price rise may simply accelerate the shift away from letter mail, deepening the volume decline that triggered it in the first place and forcing more costs onto the NHS and other bulk users. With Ofcom already investigating late deliveries and deprioritisation claims, there is a real risk the squeeze produces a worse, more expensive service rather than a leaner one.
