Home Improvement Loan
Make your home more comfortable while using less energy
Finance energy-efficiency improvements to your home, such as heating and cooling systems, insulation or energy management solutions. You decide where to start.

The loan requires proof of the use of the funds. You must therefore provide either the purchase invoice or the renovation quotation within a maximum period of 90 days, clearly showing that the loan proceeds have been used for one of the eligible purposes classified as sustainable. If the documentation is not provided within the required period, or if the intended use of the loan does not meet the sustainability criteria, the discount applied to your annual nominal interest rate will be reduced by 1 percentage point, effective from the fourth repayment instalment2.
