A RBS branch in Harrow will be shutting as customers switch increasingly to using online services.

The banking giant said it will close 32 sites – 21 of the closures would be Natwest and 11 of them RBS – but did not say when.

Most staff will be moved to other branches, but 12 jobs will be at risk.

Among the branches shutting will be the RBS at Harrow, Station Road, and the Natwest in Ruislip.

“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,” the bank said.

“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.”

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.
