Free £100 bonus payments will soon start arriving in Nationwide customers' bank accounts from this week.

Britain's biggest building society has confirmed the cash giveaway as part of its Fairer Share scheme.

Over four million people will qualify for the bonus payments, which will start landing in accounts within days.

To be eligible, people need to have a current account with Nationwide, as well as either a qualifying savings account or a mortgage.

Qualifying customers should have been sent a letter or email letting them know about the cash boost.

When will the £100 bonus arrive?

Bonus payments will start entering bank accounts on Wednesday, June 18.

All the money should be paid out by July 4 as part of Fairer Share, which first launched in 2023.

The giveaway is not guaranteed to run every year but depends on financial performance.

The banking giant said: "The Nationwide Fairer Share Payment is £100 for the third year running.

"Over four million of our members will receive it.

"Eligible members will receive their £100 payment between June 18 and July 4, 2025.

"We will only pay the money into an open Nationwide current account."
