ASDA Barnsley on Old Mill Lane normally opens from 8am to 10pm on Monday, then trades continuously from Tuesday through Friday, remains open from midnight to 10pm on Saturday, and opens from 10am to 4pm on Sunday.
This makes Barnsley one of the ASDA branches where a simple “24 hour store” label needs context. It is open around the clock through much of the working week, but not across the whole seven-day period.
How the Continuous Opening Period Works
The easiest way to understand ASDA Barnsley’s timetable is as one long block of trading.
The supermarket closes at 10pm on Monday, reopens on Tuesday and then stays open continuously through Tuesday, Wednesday, Thursday and Friday. Saturday begins at midnight as part of the same trading period and continues until 10pm.
The store then closes overnight before reopening at 10am on Sunday.

Can You Shop at ASDA Barnsley Overnight?
Yes, during the normal continuous trading period from Tuesday through Friday and into Saturday.
A 2am shop on Wednesday or Friday would normally fall within the store’s published opening hours. A 2am visit on Monday or Sunday would not.
This distinction matters because search results can shorten the answer to “ASDA Barnsley is open 24 hours” without explaining which days that applies to.
Sunday Resets the Schedule
Sunday hours are normally 10am to 4pm, making it the shortest shopping day of the week.
Once the supermarket closes at 4pm on Sunday, it remains closed until 8am Monday. Monday then follows a conventional 8am to 10pm timetable before the long continuous opening period starts again on Tuesday.
Barnsley Has More Than One ASDA Location
The Old Mill Lane Superstore is not the only ASDA in the wider Barnsley area.
ASDA also lists stores at Grimethorpe, Silkstone and Thurnscoe. Those branches have different opening patterns, so the 24-hour midweek schedule should not be applied to every ASDA carrying a Barnsley-area address.
Use the ASDA store locator and check that the result is for Old Mill Lane, Barnsley S71 1LN.
Click and Collect Has Its Own Timetable
The Barnsley Superstore has a drive-through grocery collection point.
Collection should be treated separately from the supermarket’s overnight opening. A branch that is open at 3am does not necessarily offer grocery collection at 3am.
Your booked collection slot is the relevant time for an online order. The ASDA Click and Collect guide explains how grocery collection works.
24-Hour Grocery Shopping Does Not Mean 24-Hour Services
Departments and staffed services inside a large supermarket can use shorter timetables than the main grocery store.
If your reason for visiting is pharmacy, opticians, travel money, a cafe or another staffed service, check that service specifically rather than relying on the supermarket’s 24-hour opening period.
Quieter Hour at ASDA Barnsley
The Old Mill Lane branch currently offers a Quieter Hour from 2pm to 3pm Monday through Thursday.
ASDA reduces background noise during that period by switching off ASDA Radio and limiting tannoy announcements to emergencies. The store remains open to all customers.
Bank Holidays Can Interrupt 24-Hour Trading
Normal overnight opening should not be assumed on a bank holiday or festive date.
ASDA can replace the ordinary timetable with Holiday Hours, so a Tuesday, Wednesday or Friday that would normally be open 24 hours can still use reduced trading around Easter, Christmas or another holiday.
This is particularly important if you are planning to travel in the middle of the night, when a temporary closure is easy to overlook.
