Biggleswade Post Office will be closing for two weeks while a refit takes place.
The Bonds Lane post office will close its doors at 5.30pm on Saturday, February 8 and will re-open on Friday, February 21 at 1pm.
As part of plans to modernise the post office network the Biggleswade branch will be renovated so it has four serving positions and a more open-plan look and feel.
There will be two open-plan counters, a screened serving position and a serving point for retail sales.
During the refurbishment period customers can use the Stratton Way Post Office and Langford Post Office in Langford High Street.
Julia Marwood, post office regional network manager – south said: “We understand how important having a post office is to residents in this area of Biggleswade.
“The modernisation is part of a major investment programme to convert the Post Office network to new-style branches.
“This investment – the largest in the history of the Post Office – also makes a commitment to not having any more post office branch closure programmes.”
