Ecologically-built HQ   
  • Comment on ethical savings, mutual governance, sustainable mortgages, energy efficiency, self build, community and co-housing, social and environmental aspects of finance
  • Details of our savings and mortgage products, including our innovative C-Change mortgage discount schemes
  • Case studies and images of savers and borrowers, including self builds, exemplar eco-homes and renovations

We lend throughout the UK, specialising in renovation and new build mortgages on properties and projects that respect the environment. We are particularly interested to see derelict and dilapidated property brought back into use.  We also promote and support the fitting of energy efficiency measures into existing homes, and the provision of affordable housing, including housing cooperatives.

Our C-Change mortgage discounts support homeowners to cut the energy consumed in their properties, including our C-Change Retrofit scheme for owners who want to upgrade the energy efficiency of their existing home.

Our savers invest with us in the knowledge that they are helping to support sustainable development.  We offer a range of straightforward accounts including penalty free easy access, notice and cash ISA options.

We operate throughout the UK from our eco HQ. We were the first Building Society to offer ‘green mortgages’ and have been doing so since 1981.
