How much can I borrow?
Mortgage CalculatorOur simple-to-use mortgage calculator will help you work out how much you could borrow and compare monthly payments for our Self-build, Conversion, and Renovation mortgages. You'll also be able to see how much you could save if you're eligible for our C-Change discount.
Our mortgage calculator is for illustrative purposes only and is designed to give an indication of the amount that we may be able to lend. The actual amount that we may be able to lend will depend on a full assessment of affordability, the property value and the size of your deposit.
Ecology Building Society was rated as an ethical Best Buy for our mortgages, ISAs and savings accounts by Ethical Consumer magazine in its product guide rankings (May/June 2018 issue).
Looking to finance your new build project? We are currently focusing on self-build projects aiming for Passivhaus, EPC A or EPC B (SAP rating 85+) as they result in the greatest carbon reductions.
