Primary Audience: West Midlands DTC founder
Summary: Royal Mail’s April 2026 postcode exclusions are a reminder that ‘next day’ is a postcode promise, not a vibe. Tighten your delivery promise logic before your CS inbox pays for it.
Suggested Posting Day: Monday
If your checkout still says “Next day delivery” like it’s a national truth…
You’re about one postcode list away from a customer service headache.
Royal Mail quietly updated its delivery speed exclusions for Royal Mail 24/48 and Tracked 24/48 from 13 April 2026.
That’s not drama. That’s ops.
The bit founders miss: ‘Tracked 24’ isn’t a brand promise.
It’s a carrier service with lanes that change.
On the warehouse floor, we see the same pattern every time:
Marketing promises a blanket next-day.
Ops gets the blame when AB/PH/FK postcodes don’t land like Birmingham does.
Mini example:
A West Midlands DTC brand was running a “order by 8pm, delivered tomorrow” line.
Great for conversion.
Then we hit a cluster of excluded postcodes and the complaints came in: “you’ve lost my parcel”.
Nothing was lost. The promise was.
Practical takeaway:
Split your delivery promises by postcode group and cut-off time.
Even a simple “UK Mainland next day (exclusions apply)” plus a proper exceptions page will save you refunds and chargebacks.
How are you currently setting delivery expectations — one headline promise, or something that matches how the network actually behaves?
