Ecology and The Green Party


We specialise in sustainable mortgages for renovation and new build properties and projects, and we're particularly interested to see derelict and dilapidated property brought back into use, or energy efficiency measures fitted into existing homes. We also support the provision of affordable housing, including housing cooperatives. 

Our C-Change retrofit scheme aims to support homeowners wanting to improve the energy efficiency of their property, with a discount of 0.25% for every grade improvement in your home's Energy Performance Certificate (EPC) from our Standard Variable Rate, currently 4.65%. 

Representative example:
A mortgage of £95,300 payable over 25 years on our Standard Variable Rate, currently 4.65%, would require 300 monthly payments of £537.85.
The total amount payable would be £161,595 made up of the loan amount plus interest (£66,055) and a valuation fee of £240 (assuming a purchase price of £200,000).
The overall cost for comparison is 4.80% APRC representative.

An early repayment charge may be payable if you repay all or part of your mortgage within the first two years.


Green Party mortgage referral offer 

Ecology will waive our mortgage application fee for mortgages referred by the Green Party. Please advise us on your application form if you wish to take up the Green Party referral offer and if you would like to be considered for our C-Change retrofit discount - to be eligible applicants will need to provide an EPC for the property before works begin.   For borrowers who request a C-Change retrofit discount, we will pay for the final EPC assessment once works to the property have been completed and evidenced.
