Here, Which? looks at why people have been switching and explains how to move to a new bank or building society if you're tempted to follow suit.
The latest data from Pay.UK shows how many people moved to and from the main current account providers between 1 April and 30 June 2020.
Below we've set out how the banks and building societies fared.
The bank managed to entice customers despite lowering interest rates; Starling previously paid 0.5% AER on balances up to £2,000 on a maximum balance of £85,000. However, as of 18 May you can only earn 0.05% on up to £85,000.
The offers a cheap overdraft as well as fee-free purchases and foreign ATM withdrawals anywhere in the world. It also has a range of app features such as instant notifications to help you spot fraud immediately.
Monzo and Nationwide also saw big net gains, at 11,393 and 10,083 respectively.
Monzo just missed out on the top spot, but may see higher net gains next time data is published. It recently announced the , a new packaged bank account that comes with a host of additional services, although it costs £15 a month and you have to sign up for a minimum of six months.
Nationwide is usually a top contender; it was the biggest winner , achieving a net gain of almost 26,500. Its FlexDirect account was a popular choice with its 5% AER interest offer on balances of up to £2,500 for 12 months. However, due to coronavirus, it to 2% in year one on balances over £1,500 in May. Many may have rushed to switch to take advantage of the higher rate before it disappeared.
Switching dipped significantly between 1 April and 30 June owing to the COVID-19 pandemic and a reduction in perks.
Less than 30,000 switches took place in May and June and just over 41,000 in April, according to Bacs. This compares to 113,037 in March.
Generally, banks have been focusing on their current customers to help them through the crisis. For instance, First Direct closed its doors to new customers in March until last month, meaning its current account switching offer of £100 for its 1st Account was also taken away and is not currently being offered.
Almost all of Britain's high street banks had pulled switching bonuses, with three-figure switching offers from the likes of HSBC and NatWest disappearing.

Bacs data shows 136,575 switches took place between the start of July and the end of September - 38,383 more than the period 1 April to 30 June.
With cash incentives being reintroduced, this figure may increase further in the last quarter of the year (1 October to 31 December).
Some people may be incentivised to switch to grab higher interest rates - the highest at the moment are Virgin Money's 2.02% on £1,000 and Nationwide's 2% on £1,500.
Others may find their bank introduce new charges.
HSBC this week announced it could start charging for 'basic banking services' because of the low rate environment. It says it's considering charging for products like current accounts, which are currently free to UK customers.
