The Big Bank Switch
The UK’s big banks are financing companies that are fuelling the climate crisis and harming nature.
Switch to a greener bank with the Big Bank Switch and you’ll join a growing movement of Christians taking action with their finances to care for God’s creation.
Make your Big Bank Switch Pledge! Explore greener options for your current account, and start your switch today.
*Why make a pledge? There is power in numbers. Your pledge will be counted as part of our collective call for change. You can then make the switch at a time convenient for you.
Not sure if your bank is green? Use Bank.Green’s tool to check.
The Big Bank Switch is coordinated by JustMoney Movement, Operation Noah, Just Love and Laudato Si’ Movement.

October 2025 update: We have previously included Nationwide as a fossil-fuel free bank but are reviewing their inclusion in the Big Bank Switch. Which? research shows that Virgin Money (bought by Nationwide in 2024) has some exposure to fossil fuels, through loans to field services that serve the oil and gas industry. We are engaging with Nationwide on this issue. If you are a customer of Nationwide and would like to write to them, please see the template message below.
