The Post Office in Earls Barton will next month be the latest store in the county to move to new premises.
The branch will open in the Premier store, Station Road, at 1pm on Thursday, August 18.
A Post Office spokesman said: “It will be a modern open-plan local-style branch with extended opening hours.
“Post Office services will be delivered from an open-plan till at the convenience store’s counter.
“Services would be provided throughout the shop’s new opening hours, which are Monday to Friday, 7am to 7.30pm; and Saturdays and Sundays, 7.30am to 7pm.
“This will be an extra 44 hours a week of Post Office services including all-day Sunday and Saturday afternoon.
“The branch will also open significantly earlier and close much later.
“It will also mark an end to lunchtime closing.”
The current branch in The Square will close with the current postmaster’s agreement at 5.30pm on Wednesday, August 17.
Customers who need to visit a post office during the morning of Thursday, August 18, are advised to use the branch in Northampton Road, Wellingborough.
Post Office regional manager Will Russell said: “We are making it easier for customers to get their cash, send and collect their mail and do their banking because we know how important these services are to local residents.
“We are confident that this vibrant new-style Post Office at the heart of the local community will meet customer needs.
“This modernisation is part of a major investment programme, the largest in the history of the Post Office and will secure services for the future.”
