Morrisons standard online grocery orders use 1-hour delivery windows. You choose an available slot during checkout, and Morrisons says it aims to deliver within your chosen slot. Your confirmed delivery time is then shown in your order confirmation email.

That sounds simple, but in practice the important part is availability. You are not selecting from a fixed timetable that is always open. You are selecting from the slots Morrisons is currently offering in your area at that time.
What a Morrisons Delivery Slot Actually Is
A delivery slot is the 1-hour window Morrisons gives you for your grocery order to arrive. So if you book, for example, a 6pm to 7pm slot, Morrisons says it will aim to deliver during that period rather than at an exact minute.
That distinction matters because shoppers sometimes expect a precise arrival time, when the system is really built around a one-hour arrival window. The slot is part of the wider Morrisons online grocery process, so it also affects how shoppers think about Morrisons delivery cost and whether a particular order feels good value.
Where You See Available Slots
Morrisons says you can browse and book available dates through the normal Book a delivery process, including by using the calendar icon to move through future dates when relevant, such as at Christmas. Availability is subject to what is open when you look.
So the experience is less like reserving a permanent timetable and more like checking what the system is currently able to offer your postcode.
Do Morrisons Delivery Slots Stay Reserved While You Shop?
Not forever.
Morrisons says your order slot will expire after 60 minutes if you have not checked out your order. If you need longer, it advises checking out first and then editing the order later, as long as you are still before the cut-off time.
This is one of the easiest ways to lose a good slot. A shopper may think the slot is safely held while they continue browsing, but Morrisons makes clear that it times out if checkout is not completed in time. That is often the hidden reason people later feel that delivery slots have disappeared.
Can You Change the Order After Booking a Slot?
Yes, usually.
Morrisons says you can sign in, go to My Account, open Orders, and click Edit on the order you want to amend. But the important detail is that you must complete checkout again or the changes will not be saved. Morrisons also notes that cut-off times vary, with the details shown in your order confirmation email.
So booking a slot does not always lock the basket completely, but it does put you on the clock. For shoppers who often add or remove items after checkout, Morrisons order changes are an important part of making the slot work properly.
What Time Will Your Morrisons Order Arrive?
Morrisons says it always aims to deliver within your chosen slot and advises customers to be home during that time. It also says you should look out for delivery updates on the app or website, while the scheduled delivery slot itself is shown in the confirmation email sent to your registered email address.
That means the email is your main reference point, while the app or website may help with updates closer to the delivery. If your main concern is arrival timing rather than booking the slot itself, Morrisons delivery time explains that side of the experience more directly.
What If You Miss the Delivery Slot?
If you are not home to accept the order, Morrisons says the driver will attempt to contact you. If contact cannot be made, the order may be cancelled. Morrisons also says it cannot guarantee the driver will be able to return the same day, and you may still be charged for perishable items if the order is cancelled because the delivery was missed.
That makes the slot more than just an estimate. It is effectively your agreed acceptance window, so being available during the confirmed hour matters.
Are Morrisons Now Slots the Same Thing?
No. Morrisons Now works differently.
Morrisons says there is no need to book a slot time for Morrisons Now because it delivers in as little as 60 minutes from checkout, where available in your area.
So when people talk about Morrisons delivery slots, they are usually referring to the standard online grocery service, not Morrisons Now. That difference is important because it changes what the customer should expect: booked 1-hour windows for standard delivery, versus rapid delivery without slot selection for Morrisons Now. For urgent top-up orders, Morrisons fast delivery works on a different timetable from standard grocery slots.
Why Good Slots Sometimes Feel Hard to Get
Morrisons does not promise that every slot will always be available. Its help pages consistently frame booking around available slots, which means timing, demand, and postcode all shape what you can actually choose.
That is why some shoppers find lots of choice on one day and very little on another. The system is based on what Morrisons can currently release, not on a permanent list of guaranteed times. When the useful windows are gone or nothing suitable appears, the issue becomes closer to Morrisons delivery slots unavailable.
A Better Way to Think About Morrisons Slots
Instead of thinking, “What time does Morrisons deliver?”, it is more useful to think, “Which 1-hour windows is Morrisons offering me right now?”
That mindset fits the way the service is actually structured:
- you choose from currently available windows
- the slot must be checked out before it expires
- Morrisons then aims to deliver within that confirmed hour
Once you understand that, the booking process feels much less confusing.
How Delivery Slots Fit into Morrisons Online Shopping
Delivery slots are one of the main parts of the wider Morrisons online grocery journey. They affect when the order arrives, how convenient the service feels, and sometimes how much the order costs.
That is why slot choice should not be treated as a small checkout detail. It sits alongside minimum order rules, delivery charges, order changes, and fast-delivery options. The wider process is easier to understand through the Morrisons online shopping guide.
Final Thoughts
Morrisons delivery slots are built around 1-hour delivery windows, not exact-minute appointments. You book from the slots available for your area, your slot can expire if checkout is not completed within 60 minutes, and Morrisons says it aims to deliver within the confirmed hour shown in your order email.
The biggest mistake shoppers make is assuming a slot is permanently held while they keep browsing. In reality, the booking system rewards quick checkout and attention to the cut-off rules. Once that is clear, Morrisons delivery slots make much more sense.
