The Post Office is pressing ahead with plans to move its Civic Square branch to the Family Shopper in Airbles Street, Motherwell.
A survey of the building has found asbestos in the roof, but the post office refused to discuss the matter directly.
A Post Office spokesperson said: “We are currently working with the new postmaster on the preparations to install the Civic Square Post Office in his shop.
“Following the release issued in August we will confirm details and dates in due course.”
Services will be provided from 7am-10pm Monday to Saturday and 8am-10pm on Sundays from two open-plan counters in the store including special delivery, local collect, home shopping returns, online banking cash deposits and withdrawals.
The current location in Civic Square remains open until the changes take place.
