How to handle disconnection from central heating
Disconnecting from central heating is a recurring request at condominium assemblies, usually driven by a wish to save money or control temperature independently. Italian law allows it, but only under precise conditions that protect the shared system and the owners who remain connected. Article 1118 of the Civil Code states that an owner may waive use of the centralized heating system only if the disconnection does not cause significant operational imbalances or additional costs for the other owners. Even after disconnecting, the owner remains liable for the share of extraordinary maintenance and conservation costs of the system. This guide explains the conditions, required documentation, cost allocation and how to manage the resolution, with tools like AmministraPro helping track every step correctly.
The conditions set by article 1118 of the Civil Code
The right to disconnect is not unconditional. The law requires the owner who intends to waive use of the centralized system to prove, through a technical report, that the disconnection does not cause significant operational imbalances in the system nor additional costs for the owners who remain connected.
In practice, the technical report must verify that the boiler and distribution network continue to operate efficiently even with one fewer unit connected, and that the resulting lower overall consumption does not raise the unit cost for the others. If these conditions are not met, the assembly or an objecting owner can legitimately oppose the disconnection.
- Technical report from a qualified professional confirming no imbalance
- No additional cost for the owners who remain connected
- Formal notice to the property manager before the work
- Actual physical disconnection of the unit from the shared system
Which costs remain due even after disconnection
Disconnecting does not exempt an owner from contributing to all system costs. The owner who disconnects still owes their share of extraordinary maintenance and conservation costs for the centralized system, because the system remains a shared asset whose conservation benefits everyone, including those who no longer use it, in terms of building upkeep and property value.
What ends instead is the obligation to contribute to ordinary service management costs, such as fuel consumption and routine burner maintenance, which are directly tied to actual heat use. The distinction between conservation costs, always owed, and service management costs, owed only by those who use the system, is where most disputes on this topic arise.
How costs are allocated after a disconnection
After a disconnection, the financial statement must clearly separate the two cost categories. Conservation and extraordinary maintenance costs remain allocated among all owners according to their ownership shares or the thermal shares set during metering, regardless of actual use.
Service management costs, including heat actually supplied, are allocated only among the owners who remain connected, based on recorded consumption where individual metering is in place, or on the revised allocation tables. Management software such as AmministraPro keeps these two calculation tracks separate in the financial statement, avoiding manual errors that lead to disputes at the assembly.
The role of the assembly and the resolution
Disconnection itself does not require an authorizing assembly resolution: it is an individual right of the owner, exercised through formal notice accompanied by the technical report. The assembly nevertheless steps in to acknowledge the change, update the cost allocation plan, and, if necessary, challenge the technical report if it believes the imbalances described in article 1118 actually exist.
It is good practice for the property manager to call an informational assembly after receiving the disconnection notice, so the financial statement can be formally updated and future disputes prevented. Recording the acknowledgment in the minutes and promptly updating the allocation tables significantly reduces the risk of conflicts between owners.
Frequently asked questions
Can an owner disconnect from central heating without the assembly's permission?
Yes, disconnection is an individual right under article 1118 of the Italian Civil Code and does not require prior authorization from the assembly. However, the owner must prove, through a technical report from a qualified professional, that the disconnection does not cause significant operational imbalances in the system nor additional costs for the other owners. If these conditions are not met, the other owners can object, and in case of dispute a court will assess the technical report.
What costs must an owner who disconnects from central heating keep paying?
An owner who disconnects still must pay their share of the system's conservation and extraordinary maintenance costs, because the system remains a shared asset that retains value for the whole building. What ends is the obligation tied to ordinary service management, such as fuel consumption, which remains due only from those who actually use the system.
Is a technical report required to disconnect from central heating?
Yes, the technical report is the evidence required by article 1118 of the Civil Code: it must be prepared by a qualified professional and must demonstrate that the disconnection does not cause significant operational imbalances in the centralized system nor an economic burden for the owners who remain connected. Without this document, the disconnection request lacks the technical basis required by law.
How is the condominium financial statement updated after a disconnection?
The statement must separate conservation and extraordinary maintenance costs, allocated among all owners according to ownership shares regardless of use, from heating service management costs, allocated only among the owners who remain connected based on consumption or updated allocation tables. Management software such as AmministraPro handles these two allocation tracks separately, with full traceability for the assembly.
Can the property manager oppose an owner's disconnection?
The property manager has no independent decision-making power over disconnection, but can and should verify that the notice received is accompanied by the technical report required by law, and, if there are well-founded doubts about operational imbalances, bring the matter to the assembly so owners can consider a formal challenge, including in court if necessary.
