The Brecon branch of Barclays is set to close permanently later this year.
The branch, located on The Bulwark, will close its doors on Friday, August 25.
The bank has cited a drop in the number of customers using the branch of the main reason for its closure.
According to Barclays, 85 per cent of people who use the Brecon branch have also banked using the app, online and by phone in 2021. They also added that just 26 customers use this branch regularly, as the only way to do their banking.
Barclays has said it will be working with the local community to understand the impact of closing this branch.
A spokesperson for Barclays said: "We’ll continue to be part of your community in Brecon. We’re just finalising the arrangements of where and when our colleagues will be to support you, and as soon as they are confirmed we’ll share the details."
Following the closure, the nearest Barclays branches available will be in Builth Wells and Abergavenny.
