Changes to the electricity connection

The size of the main fuse affects the connection’s capacity and the load on the electricity grid. Any change must always be agreed upon with the grid company to ensure safe use of the connection and the network in accordance with capacity.

The duration depends on the scope of the change. For minor cases, an electrical contractor can complete the work within a few days, but if reinforcements to the grid are required, the process can take several weeks.

The size of the current main fuse can be found on your electricity bill, on the fuse panel in the metering cabinet, or in documents provided by your electrical contractor. If necessary, you can also ask Herrfors Nät-Verkko’s customer service.

Three-phase conversion means that a single-phase connection is converted to a three-phase connection. This increases the connection’s capacity and enables the use of more powerful equipment.

It is advisable when installing, for example, a heat pump, an EV charger, larger electrical devices, or when the current single-phase connection is insufficient.

The customer contacts an electrical contractor who assesses the need and submits a notification to Herrfors Nät-Verkko. Herrfors installs a new meter, converts the connection to three-phase, and updates the connection agreement.

The metering cabinet must be renewed if it is outdated, damaged, or no longer meets current safety and installation standards. Renewal is also often required when the connection is upgraded or when the building undergoes major renovations.

The metering cabinet is the customer’s property, and its maintenance is the customer’s responsibility. Herrfors Nät-Verkko is responsible for the metering devices and the accuracy of the measurement, but the maintenance and any necessary repairs of the cabinet itself are the responsibility of the property owner.

In an easily accessible location, usually on an exterior wall or at the property boundary.

The connection cable must be renewed if it is damaged, undersized for increased consumption, or no longer meets safety standards. Renewal may also be required if the connection is upgraded.

The connection cable from the property boundary to the property’s main distribution board is the customer’s property and responsibility. Herrfors Nät-Verkko is responsible for the cable towards the grid.

Yes, the connection cable can be relocated, for example due to construction or landscaping work. The work requires an electrical contractor and notification to Herrfors Nät-Verkko. The costs are borne by the customer. 

Maintenance means that the connection is not actively used but is preserved for future use. Electricity is not supplied to the customer, but the connection remains ready for use.

Maintenance is a good option if the property is unoccupied for a long period, the building is demolished but a new one is planned, or if electricity use is suspended for an extended time.

The basic charges remain the same as during normal use. No electricity is consumed, so billing consists only of the basic charge based on the main fuse size. In addition, a disconnection fee for the connection cable is charged according to the service price list. 

Termination is done using an electronic order form on our website. Herrfors Nät-Verkko disconnects the connection, removes the meter, and the contract ends. 

No. A connection is always tied to the property and cannot be moved to another address. A new property requires a new connection.

No. The connection fee is a one-time payment for building the connection and is not refunded upon termination.

The electricity connection is always tied to the property and cannot be moved. In the event of a change of ownership, the connection automatically transfers to the new owner.

Yes. Both the previous and the new owner must inform Herrfors Nät-Verkko’s customer service or use an electronic form. This ensures that contracts and billing are correctly assigned. 

Yes. The new owner can keep the connection active, place it in maintenance, or terminate it completely.

You need an inspection of the installations carried out by an electrical contractor. The contractor submits an inspection report to the network company, after which the electricity can be safely switched on.

Yes. Before reconnection, you must have a valid electricity sales contract with the electricity supplier of your choice. Without it, the network company cannot switch on the electricity.

The network company performs the reconnection after the electrical contractor has submitted the inspection report. The reconnection will be carried out as soon as possible, usually within a few working days.
