Your Green Together Reward
As part of our commitment to protecting the planet, we are offering eligible customers £500 if they make energy efficient home improvements

What is Green Together?
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 with a TrustMark registered business, 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.
