ASDA Grantham on Union Street currently opens from 8am to 10pm on Monday, 7am to midnight from Tuesday through Friday, 7am to 10pm on Saturday, and 10am to 4pm on Sunday. The Superstore is at Union Street, Grantham, NG31 6NZ.
Grantham also has a separate ASDA Colsterworth Express Petrol on the A1 South Bound that is open 24 hours every day. The 24-hour Express location should not be confused with the Union Street supermarket, which closes each night.
Start With the Type of Visit You Are Making
A Grantham visit can have very different useful times depending on whether you are shopping for groceries, collecting an order, visiting the pharmacy or simply buying fuel.
The supermarket itself provides the longest in-store window from Tuesday through Friday, but several services operate for fewer hours.
For a Full Grocery Shop
- Monday: 8am to 10pm
- Tuesday: 7am to midnight
- Wednesday: 7am to midnight
- Thursday: 7am to midnight
- Friday: 7am to midnight
- Saturday: 7am to 10pm
- Sunday: 10am to 4pm
Tuesday through Friday are the most flexible days because they combine a 7am opening with a midnight closing.
Saturday keeps the 7am start but closes two hours earlier. Monday starts at 8am and also closes at 10pm.
For Grocery Collection
The Drive Thru Collection Point currently operates from 7am to 8pm Monday through Saturday and from 7am to 6pm on Sunday.
The service therefore starts before the supermarket on Monday and Sunday. Monday collection begins at 7am while the shop opens at 8am, and Sunday collection begins at 7am while normal supermarket trading starts at 10am.
Tuesday through Friday show the opposite difference at night. The supermarket remains open until midnight, but grocery collection finishes at 8pm.
The ASDA click and collect guide explains the wider process, while the slot attached to your individual order should determine your arrival time.
For Pharmacy Visits
ASDA Grantham Pharmacy currently opens from 9am to 9pm Monday through Saturday and from 10am to 4pm on Sunday.
That means the pharmacy opens after the supermarket and closes before it from Monday through Saturday.
On a Thursday, for example, grocery shopping can continue until midnight while pharmacy access finishes at 9pm.
For George Collection
George Click & Collect currently operates from 8am to 10pm Monday through Saturday.
ASDA’s current listing gives a wider Sunday George collection period of 9am to 6pm. That begins before the supermarket’s 10am opening and continues after its 4pm close.
Customers are directed to the internal touch screen near the store entrance for George collection.
For Fuel, the Answer Is 24 Hours
The petrol filling station at the Union Street store is currently listed as open 24 hours every day.
Fuel can therefore remain available when the supermarket is closed, including late Saturday night and before Sunday supermarket opening.
There is also the separate ASDA Colsterworth Express Petrol on the A1 South Bound near Grantham, which ASDA also currently lists as open 24 hours every day.
Scan & Go Has an 8am Handset Start
ASDA currently lists its Scan & Go handsets from 8am to 10pm Monday through Saturday and from 10am to 4pm on Sunday.
The mobile Scan & Go app is listed separately as available 24/7. This means a 7am shopper can enter the supermarket on Tuesday through Saturday before the physical handset period begins.
Sunday Has Several Overlapping Timetables
The supermarket currently opens from 10am to 4pm on Sunday. The pharmacy and listed Scan & Go handset period match that six-hour window.
Drive Thru grocery collection is broader at 7am to 6pm, while George Click & Collect is currently listed from 9am to 6pm.
This makes Sunday a good example of why the main store hours do not automatically define every service at Grantham.
Quieter Hour and Special Dates
ASDA Grantham currently offers quieter hour from 2pm to 3pm Monday through Thursday.
Bank holidays can replace the normal timetable with date-specific hours. The ASDA opening hours information gives broader context, but check the Union Street branch itself for a particular holiday.
