We’re dedicated to building a greener society by providing mortgages for properties and projects that respect the environment and support sustainable communities, funded through our range of simple, transparent savings accounts When you save with us, you know your money is being used to help build a more sustainable future. We’re a building society dedicated to improving the environment by supporting and promoting ecological building practices and sustainable communities. We were established in 1981 by a group of pioneering founder members who wanted to start a building society to help finance environmental building renovations and support sustainable development. Since then we have expanded the reach of our lending but throughout we remain committed to our mission and ethical principles.
