Barclays to expand branch network after closing 80% of locations since 2019

Barclays plans to expand its high street presence by opening new branches and enlarging existing sites, reversing years of closures, UK CEO Vim Maru told The Times. The bank currently operates 206 branches after closing nearly 80% of its network since 2019. Maru said the expansion aims to combine digital services with in-person assistance, targeting personal customers and newer businesses. He emphasised differentiating from app-based rivals like Revolut by offering human support alongside digital capabilities. The bank is also reintroducing the "bank manager" job title and applying AI to internal processes. Barclays recorded peak mortgage applications last year and has reduced application times from 45 to 15 minutes. Maru said organic growth remains the priority over acquisitions.
