Royal Mail is recruiting approximately 22,000 seasonal staff ahead of the 2026 Christmas peak. Carrier hiring is one of the few genuinely forward-looking signals a brand gets about peak, because a network commits to that cost months before the volume shows up. It is worth reading as a forecast rather than as news.

For a US brand selling into the UK, the practical reading is about your own dependencies rather than about Royal Mail. Peak is when the gap between a brand that planned and a brand that assumed becomes visible to customers, and it closes again in January with a lot of refunds in between.

Three things tend to go wrong, and all of them are decided well before the volume arrives.

• Stock arrives late because the inbound leg was planned against average transit times rather than peak ones, and warehouses are at their least flexible exactly when you need them most
• Cut-off dates get published on the website before they have been agreed with the carrier, so the promise on the product page is not the promise the network is running
• Returns capacity is forgotten entirely, and the January backlog damages marketplace metrics that took months to build

Cut-offs deserve particular attention. A last order date is a commercial promise, and shoppers treat it as one. Publishing a date you have not confirmed with whoever is actually carrying the parcel is the single most common way brands turn a good peak into a bad one.

There is a structural advantage for brands holding stock in-market. A UK or EU order picked from local inventory sits entirely inside a domestic network during peak, which is the part of the chain carriers have staffed for. An order that has to clear customs during the same window is competing for attention in the part of the chain nobody adds 22,000 people to.

Expandly positions stock in-market before peak builds, so your UK and EU orders are domestic parcels during the weeks when everything else is queuing.
