The number of people swapping current accounts between April and June using the official service rose by almost a third on the previous three months, data shows. After a slow start to the year, likely exacerbated by the lockdown and a lack of incentive to spend, people appear to once again be proactively looking for the best bank account deals. NatWest and Santander were the big losers during the first three months of the year suffering net customer losses of over 10,000 each - individual bank data lags three months behind the overall data. Lockdown winner: Starling Bank managed to bag the most amount of switching customers.
