About us

Our history

Ecology started as, and remains, a group of like-minded people committed to building a more sustainable future.

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.

Ethics and sustainability

We don't just support others to try to live and work more sustainability: we do it ourselves. We put our ethical principles into practice throughout our operations, from managing the environmental impact of our offices to our approach to fair pay for our staff.

More about our sustainability

Our impact

Our impact isn't about the profit we make – it's about the difference we make to the environment and to communities across the UK.

Since 1981 we've lent to over 4,500 projects, supporting individuals, charities, environmental businesses and community-led housing organisations to realise their sustainable living ambitions.

In 2021 we lent £69.4 million to support 371 sustainable properties and projects.
