According to the Association of Condominium Managers (ARC), charges increased by an average of 6.2% in 2025 compared to 2024. For a standard apartment of 80 m², this represents on average 2,300 to 2,400 euros per year.
But these figures remain national averages. In reality, the level of charges varies greatly depending on the location, the age of the building, its equipment (elevator, collective heating, caretaker) and management of the co-ownership. In large cities, they are generally higher.
Frontline energy and maintenance
Energy remains the main factor in increasing costs. According to the Manda trustee’s barometer, based on the condominiums he manages, the heating bill has increased by 26% in three years, a movement reinforced by the end of the tariff shield in 2025, little affected by the drop, announced by Sébastien Lecornu, in certain electricity prices at the start of 2026.
Routine maintenance also contributes to the increase in costs. Maintenance, cleaning, insurance, repairs… Expenses constantly increasing with inflation, which combined quickly increase the bill.
Local taxation also weighs on costs. In 2025, the cadastral rental values were revalued by around 1.7%, which leads to an increase in tax provisions (sums set aside by the co-ownership to pay certain taxes linked to the building). A discreet, but very real increase in fundraising.
How to contain the increase in costs
While not all increases can be avoided, some can be limited. Part of the savings comes first through contracts. In many co-ownerships, certain services are automatically renewed for years, without any real questioning. Regular competition for maintenance, cleaning or insurance contracts often allows room for maneuver to be created, without degrading the level of service.
Another key point: energy. Without incurring heavy work, finer adjustments and better monitoring of consumption can already limit the bill. In the longer term, targeted interventions on buildings or equipment make it possible to sustainably contain costs, particularly when they rely on existing aid.
Finally, anticipation remains decisive. Planning the work, making appropriate provisions and avoiding emergency decisions makes it possible to limit exceptional calls for funds. Without forgetting that minimal involvement of co-owners is sometimes enough to avoid costly excesses.
