How to set your last order dates for Christmas, before the carriers publish theirs

Every year the same thing happens. A seller copies Royal Mail's last posting date onto the shop, takes orders right up to it, and then discovers that an order placed at 4pm on that date cannot physically be picked, packed and handed over the same afternoon. The parcel goes the next working day, the customer gets it after Christmas, and the review is about the shop rather than the carrier.

The fix is not complicated, and you do not need this year's dates to do most of it.

The arithmetic

Three steps, in this order.

• Start from the carrier's last posting date for the service you actually use, not the fastest one they publish.
• Step back to your dispatch cut-off on that day. Ours is 2pm on a working day and 1pm on Saturday, so an order that lands at 2:05pm is already a day later than it looks.
• Subtract one working day. This is the margin, and it is what absorbs a card payment held for review, a stock discrepancy found at the pick face, or a courier collection that runs late.

That gives a date you can publish and keep. It will feel early. That is the point: the shops that get through December without complaints are the ones that stopped promising two days before they had to.

The table to fill in

Copy this, one row per service you sell. Fill the middle column when the carrier publishes, and the right hand column is then arithmetic rather than judgement.

A warning about copying dates off the carrier's site today

Checked on 20 September 2026. Royal Mail's own Christmas page says it will update its last posting dates for Christmas 2026, and the page those dates sit on is still titled for last Christmas and still lists last year's dates. Anyone copying dates from there this week is copying the wrong year, and will publish them on a shop as though they were current.

Last year's spread ran from the middle of December for standard services to the 23rd for the guaranteed one. That tells you the shape to plan around. It does not tell you this year's dates, and the two are not the same thing. Check royalmail.com/christmas for the real ones, and treat any date you find before they publish as a placeholder.

What is already known for this season

Three dates are set, even though the posting dates are not.

• 5 October: Royal Mail parcel prices rise, for stamps and for business accounts. The detail is in our write-up of what changes.
• 2 November to 10 January: Royal Mail's peak surcharge applies to business account customers on domestic parcels and international products.
• November and December: our own peak surcharge of 20p per order, published on the rate card rather than added later.

The whole cost picture for the quarter is set out separately in the Q4 cost calendar.

Where to put the dates once you have them

One place is not enough, because customers arrive at different points.

• A banner on every page, not just the home page.
• On the product page, near the delivery estimate, where the decision is actually made.
• At checkout, as a line of text rather than a tooltip.
• In the dispatch email, so anyone who ordered before the cut-off knows they made it.

Then take them down in January. A shop still showing a Christmas cut-off in February tells a visitor that nobody is looking after it.

What actually goes wrong in the last week

Not the carrier, usually. In order of how often we see it: packaging runs out, because the December usage was estimated from November; a bestseller sells out and the substitution is handled by email rather than by a policy; and the person who knows the process takes their own Christmas break without writing anything down.

All three are September and October problems pretending to be December problems. The month by month version of that plan is in peak season starts in September, not November.

Christmas cut-offs, answered

When does Royal Mail publish its Christmas last posting dates?

Royal Mail publishes them on its own Christmas page in the autumn, ahead of the season. As of 20 September 2026 the dates for this year are not out yet. Rather than wait on them to plan, set your own last order dates from the method below and confirm them against the posting dates when they land.

What is the difference between a last posting date and a last order date?

The posting date is the carrier's deadline for handing a parcel over. The last order date is yours, and it has to be earlier, because your order still has to be picked, packed and dispatched. Publishing the carrier's date as your own is the single most common way sellers miss Christmas.

How do I work out my last order date?

Take the carrier's last posting date for the service you use, step back to your own dispatch cut-off on that day, then subtract one working day of margin. With our 2pm weekday cut-off, an order placed at 1pm on the posting date still makes it, but there is nothing left if anything goes wrong, which is what the margin day is for.

Should I stop taking orders after my last order date?

No. Keep selling, and change what you promise. Say clearly that orders after that point are not guaranteed for Christmas, and most customers will still buy. What damages a shop is a promise it cannot keep, not an honest cut-off.

Does Angler's dispatch cut-off change over Christmas?

No. It stays at 2pm Monday to Friday and 1pm on Saturday all the way through, and it is written into clause 10 of our terms rather than into a seasonal notice. Our peak surcharge of 20p per order applies in November and December and is on the published rate card.
