Around 3.4 million Nationwide Building Society members are in line for a free £100.
The bank has launched Nationwide Fairer Share - a new reward for its members "with the deepest relationships". A £340 million pot will be distributed to eligible members holding a qualifying current account plus either a qualifying savings or mortgage product.
Payments will be sent out automatically to account holders in June, assuming they held their qualifying products on March 31 2023. Nationwide will start to inform eligible members about the payment from Friday.
