New loan data from KBC reveals a striking dichotomy in Belgium’s green transition: while the nation’s overall progress on home renovations continues to lag, the bank is witnessing a significant surge in consumer demand for energy-efficiency financing. This trend highlights a growing homeowner appetite for sustainability that is currently outpacing broader national momentum.
A granular look at KBC’s 2025 lending activity shows a clear shift towards green home improvements. The number of energy-specific loans jumped by 19%, propelled by remarkable growth in key technologies. Financing for home batteries skyrocketed by 160%, while loans for heat pumps saw a substantial 30% increase. This enthusiasm extends beyond targeted energy projects, as the total number of new renovation loans also grew by 14%, indicating a wider willingness among consumers to invest in upgrading their properties when financial pathways are available.
However, this positive momentum within KBC’s customer base stands in sharp relief against the national backdrop. A KBC research report confirms that Belgium’s renovation rate is far too slow to meet its 2050 climate targets. The country underperforms its European peers, with just over 10% of homes heated or cooled by renewable energy, less than half the EU27 average of approximately 25%. This national slowdown is further evidenced by macro-level data showing consumer loans for energy renovations falling from a peak of 61,000 in 2022 to only 31,000 in 2024. Achieving the 2050 goal would necessitate a colossal investment estimated at 350 billion euros.
The primary bottleneck remains financial capacity, a hurdle that disproportionately affects lower-income households often living in the most energy-inefficient buildings. Recognizing this affordability gap, KBC took a proactive step at the close of 2025 by launching a new financing solution for first-time buyers. This product allows borrowing up to 100% of a property’s value, directly addressing the challenge of funding both a down payment and the immediate, often mandatory, costs of energy-related renovations.
Ultimately, the disparity between KBC’s loan growth and Belgium’s national renovation rate is telling. It signals that while the consumer will to invest in sustainable homes exists, broader structural and financial support systems are essential to unlock this potential on a national scale and accelerate the pace of change required to meet the country’s long-term environmental commitments.
