More than a million UK current accounts with balances of more than £50,000 earn no interest, research has found, leaving customers heavily exposed to the corrosive effects of inflation.
There were 1.04mn accounts with balances of over £50,000 at the end of March 2026, containing a total of £116bn, according to analysis by savings account provider Spring. The average balance in these accounts was £111,537.
Derek Sprawling, head of money at Spring, said many savers were unlikely to realise how much they were losing out on by leaving sums of this size in an account paying zero interest. “Often, it comes down to convenience or habit, but with balances of £50,000 or more, the missed returns can be significant.”
