Getting an electrical connection for a new house: what to expect

Who is responsible for the connection

The network operator that covers your area owns the distribution grid and decides how the connection point is built: where the cable comes from, what capacity is available at that spot, and what work on the public network side is needed to reach your plot. This is separate from anything happening on your own property.

You, as the plot owner or someone building on it, apply for the connection and pay the connection fee the operator sets out in its offer. The operator does not do your internal wiring, and an electrician does not negotiate your connection terms. Keeping the two apart from the start avoids a lot of confused phone calls later.

How the application process usually works

You submit a connection application to the network operator, usually through their online self-service, giving the plot's address or cadastral number, the expected load (how many kilowatts you think you'll need, based on heating type, sauna, workshop, and so on), and sometimes a rough building plan.

The operator works out whether the existing network nearby has enough capacity or whether new lines, a transformer, or other network reinforcement is needed. They send back an offer with the connection fee, the technical conditions, and a deadline. Once you accept and pay, they schedule the physical work on their side.

Timelines and fees depend entirely on what your specific plot needs, so this is a case where the operator's own answer matters far more than any general rule. Confirm details directly with them rather than relying on what a neighbour's project involved.

Temporary construction connection versus permanent connection

Many building sites in Harju county start with a temporary construction-time connection: a simpler, often lower-capacity supply meant to run power tools, site lighting, and a site cabin while the house is being built. It is applied for and paid for separately from the permanent connection.

The permanent connection is sized for the finished house and its actual equipment: heating, cooker, sauna heater, electric car charger if you plan one. Some sites move straight from temporary to permanent once the building is far enough along that the final consumer unit is in place and ready to take over.

Do not assume the temporary connection will simply become the permanent one without a further step. Ask the network operator early which route applies to your project, since it affects the order in which you plan the electrical work.

Where the electrician's work begins

The network operator's job ends at the connection point, usually a cabinet or meter box at the property boundary or on the house wall. From there inward, the cable to the consumer unit, the consumer unit itself, and every circuit in the house is internal wiring, and that is the electrician's territory.

This is also where our electrical work, from 49 € per hour, picks up: running cables from the connection point into the house, fitting the consumer unit with its breakers and residual current devices, and wiring sockets, lighting, and any fixed equipment. For an existing house being upgraded rather than newly connected, a straight consumer unit replacement is priced from 350 € per job.

Keeping this boundary clear when you plan the build means the network operator's schedule and the electrician's schedule can be arranged independently, rather than one waiting unnecessarily on the other.

• Apply to the network operator with the plot details and expected load
• Confirm whether you need a temporary or permanent connection first
• Get the operator's offer accepted and the connection fee paid
• Arrange the internal wiring and consumer unit with an electrician once the connection point exists
• Check the operator's own timelines rather than assuming a fixed schedule

What to check before building starts

Before groundwork begins, confirm the exact location the operator plans for the connection point, since it affects where you route internal cabling and where the consumer unit sits inside the house. Moving it later is far more disruptive than agreeing it on paper first.

It is also worth checking with your local government whether the building itself needs a building permit or notice, separate from the electrical connection process, since the two applications run on different tracks and timings. The building register is the place to confirm what your specific project needs.

If your plot sits within a korteriühistu's land or shares infrastructure with neighbouring properties, ask early whether any shared cabling or access agreements are involved, as these can add steps to an otherwise straightforward application.
