Banca March offers up to an additional 0.30% discount on mortgages for homes with the highest sustainability rating

12 November 2025 Category: Sustainability

  • The reduction in monthly payments is determined based on Banca March’s new Sustainable Housing Report, which assesses the property from a comprehensive perspective that goes beyond energy efficiency. The discount ranges between 0.10% and 0.30%, depending on the score assigned in the report.
  • Unlike the Energy Performance Certificate (EPC), which focuses solely on energy consumption, the Sustainable Housing Report assesses more than one hundred indicators grouped into three areas: environmental, social and governance.
  • Initially, this sustainability discount applies to the 10-year mixed-rate mortgages: Mixed-Rate Mortgage and Avantio Mixed-Rate Mortgage. The intention is for the discount to be extended in coming months to the full range of Banca March’s residential mortgage products.
  • In this way, Banca March not only offers customers a competitive mortgage product, but also provides them with valuable information about the sustainability of their home .

 

Banca March announces an additional discount of up to 0.30% on mortgages for homes that achieve a higher sustainability score. The reduction in payments is determined by the Sustainable Housing Report created by Banca March, which assesses the property using ESG criteria and assigns a score that reflects its overall level of sustainability.

Unlike the Energy Performance Certificate (EPC), which focuses solely on energy consumption, Banca March’s new Sustainable Housing Report takes an integrated approach and analyses more than one hundred indicators grouped into three areas: environmental, social and governance.

Depending on the rating assigned in this report, the customer may be eligible for different discounts on the initial interest rate. The Sustainable Housing Report assesses the property and assigns it a score from 0 to 10 based on its overall environmental, social and governance performance. Homes with a high score, between 9 and 10, will benefit from a reduction of 0.30 percentage points. Those scoring between 7 and 8.99 will receive a 0.20% reduction, and those between 5 and 6.99 will receive a 0.10% reduction.

Initially, this sustainability discount applies to Banca March’s 10-year mixed-rate mortgages: the Mixed-Rate Mortgage and the Avantio Mixed-Rate Mortgage, although we expect to extend it in coming months to the entire range of Banca March’s residential mortgage products.

Thus, customers who take out the Avantio Mixed-Rate Mortgage through Avantio, Banca March’s digital branch, will be eligible for a fixed NIR of 2.25% for the first ten years, to which a reduction of up to 0.30% may be applied, depending on the score obtained in the Sustainable Housing Report. For the variable-rate period from year eleven onwards, the interest rate will range between Euribor + 0.60% and Euribor + 1.30%, depending on whether the following conditions are met: a 0.30% discount for taking out a life insurance policy, 0.20% for setting up a salary direct debit, and 0.20% for taking out home insurance.

The new Sustainable Housing Report makes it possible for more customers to benefit from these terms. By assessing a broader set of indicators than the EPC —which focuses solely on energy consumption— it is possible that certain homes with a C rating under the EPC, which are generally not eligible for discounts in the sector, may nonetheless qualify for a 0.10% discount under Banca March’s Sustainability Report.

“The launch and implementation of Banca March’s Sustainable Housing Report marks a further step in our innovation strategy linked to sustainability. We not only offer customers competitive mortgage products, but also provide them with valuable information about their home, a key asset in their wealth portfolio. Sustainability has become a decisive factor in the property market, with a direct impact on a home's value, access to finance and its long-term prospects. The application of sustainability-linked discounts forms part of Banca March’s broader strategy to offer financial solutions that provide added value, promote sustainability and support the shared growth of customers, shareholders, employees and society at large”, says Sonia Colino, Head of People, Brand and Sustainability at Banca March.
