Electrical rising mains: who owns them and who pays

A building often discovers it owns its electrical distribution the day it must be replaced, for a five-figure sum.

The rising main is the set of cables running from the delivery point at the foot of the building up to each flat’s meter. It is invisible, it crosses every common area, and nobody thinks about it — until a survey declares it worn out.

At that point one question decides everything: do these installations belong to the association, or to the public distribution network operator? The answer determines who funds works that often run into tens of thousands.

The transfer principle

The law has organised the transfer of electrical rising mains to the public distribution network. A transferred main belongs to the network operator, who maintains, renews and upgrades it without the association voting any works.

• Some mains were transferred automatically, under the conditions and deadlines set by the texts.
• Others remained the association’s property, notably where it had expressed a contrary intention.
• Status is confirmed with the network operator, not in the manager’s archives.
• A transferred main still sits physically in the common areas: access must be guaranteed.

The third point is the one boards most often miss. Asking the operator in writing is free, and the answer beats ten hypotheses at a meeting.

Signs of ageing

• Lead-sheathed or fabric-insulated cables, still present in older buildings.
• Cabinets left open, broken or unlocked in the stairwell.
• Signs of overheating, a burning smell, repeated trips.
• Cable sizes clearly inadequate for current usage.
• Visible successive interventions, bodged one on top of another.

Record these during the annual walk-through, with photographs. An open cabinet in an escape route is also a fire safety point.

Do not confuse it with common-area electrics

The rising main feeds the flats. Common-area electricity — circulation lighting, lift, ventilation, gates — is a separate installation that the association owns beyond dispute.

It ages too, and bringing it up to standard falls squarely on the building’s budget. It belongs in the multi-year works plan, like any other shared equipment.

What the board can do this year

Three simple steps: write to the network operator to establish the mains’ status, photograph the condition of cabinets and ducts during the annual walk-through, and ask the manager whether a common-area electrical survey exists and how old it is.

Those three answers avoid the costliest situation: discovering the question during an incident, with nobody knowing who should act. See urgent works for what gets decided meanwhile.

The question is not "should the rising main be replaced?" but "who owns it?" — and it is asked before the failure.
