Green mortgage reward

What is Green Together?

As part of our commitment to protecting the planet, we’re aiming to reduce the energy and resources we use in our branches and offices. And with homes and buildings responsible for significant carbon dioxide emissions, we’re also finding ways to help our customers reduce the energy they use in their households.


The Green Together Reward is a simple reward scheme open to new and existing members who apply for a mortgage or change their existing mortgage. If you spend at least £2,500 making qualifying energy efficiency improvements you can apply for our £500 Reward.


Energy efficiency simply means using less power to perform certain tasks, like switching on a light or heating water. We have more than 20 efficiency improvements you can choose from which could reduce your energy bills and help the planet. So everyone wins.
