NatWest is to close its branch in Borehamwood with the banking giant attributing the closure to customers "switching increasingly to online services".
The bank in Shenley Road will permanently close on 23 June this year.
It is among 32 branches that will be shutting its doors, including 11 RBS sites.
NatWest says most staff at its branches closing down will be moved to other branches, but 12 jobs will be at risk.
NatWest said: "As with many industries, most of our customers are shifting to mobile and online banking, because it’s faster and easier for people to manage their financial lives.
"We understand and recognise that digital solutions aren’t right for everyone or every situation, and that when we close branches we have to make sure that no-one is left behind.
"We take our responsibility seriously to support the people who face challenges in moving online, so we are investing to provide them with support and alternatives that work for them."
NatWest says its closest branches to Borehamwood can be found in Edgware, Stanmore, and High Barnet. Branches are also available in Watford, St Albans, and Potters Bar.
Many of the UK’s high street bank chains have been shutting sites for years, sparking fears that less technologically savvy customers might struggle to manage their money.
Research carried out by Which? last year for the PA news agency showed that nearly half of bank branches have been lost since 2015, or are scheduled to close.
It counted 4,735 branches that had been earmarked for closure during the period, including 736 in 2021.
