Connecting a New House to Electricity: A Complete Guide from Land to Meter

What connecting a new house to electricity means

Connecting a new house to the electrical grid involves linking your installation to the grid of the distribution operator Retele Electrice Romania S.A. (formerly E-Distributie/Enel), by building an electrical connection (bransament) and installing a meter. The process has two clear components: the part managed by the operator (the technical approval, the connection itself, the meter) and the part you carry out through an ANRE-certified company (the connection dossier, the design, the works and the DIU).

As an ANRE-certified company for building and designing electrical connections in Bucharest, Ilfov and Giurgiu, SUN WATT SRL can take over the entire process for you, from drawing up the dossier to a completed connection ready for the meter.

The 5 steps from land to meter

1. The connection dossier (the connection request)

The first official step is submitting the connection request to Retele Electrice Romania, accompanied by a complete dossier. Based on it, the operator determines the connection solution and issues the ATR. Drawing up the connection dossier costs from 900 lei and includes checking the documents and completing the standard request form.

Documents required for a new house:

• copy of the identity document (owner);
• up-to-date land registry extract (no older than 30 days);
• urban planning certificate, if required by the operator;
• the building permit or the property title of the construction;
• site plan and zoning location plan;
• details of the requested power (kW) and the type of supply (single-phase or three-phase).

2. Obtaining the ATR (Technical Connection Approval)

The ATR (Technical Connection Approval) is the document through which the operator confirms the technical solution and the approved power. The connection tariff, that is the final price you pay to the operator, is also set through the ATR. This is why our prices are indicative: the exact cost of the connection is known after the ATR and the works documentation have been issued.

Once the ATR has been issued, the connection contract is signed with the operator.

3. Designing and building the connection

The electrical connection is the physical link between the distribution grid and your connection cabinet (BMPT/BMPM). This is where the ANRE-certified company comes in, carrying out both the design and the works. The type of connection determines the indicative price:

• Single-phase connection – from 1,800 lei (typical for homes with standard consumption);
• Three-phase connection – from 2,900 lei (recommended for houses with a heat pump, EV charging, workshops);
• Underground connection – from 3,500 lei (neat, protected, often requested in new neighbourhoods);
• Temporary site connection – from 2,200 lei (used during the construction phase).

You can find full details about the work on the service page grid connection to electricity.

4. DIU – the Utilisation Installation Dossier

After the connection, you need the DIU (Utilisation Installation Dossier), which certifies that the house’s internal installation has been carried out correctly and safely. The DIU is mandatory for energisation and for signing the supply contract. The DIU documentation costs from 1,200 lei (excluding the labour for building the internal installation).

SUN WATT holds a national DIU, so it can draw up the dossier regardless of your distribution operator. See details on the DIU dossier page.

5. Installing the meter and the supply contract

With the connection built and the DIU submitted, the operator schedules the installation of the meter and energisation. In parallel, you choose an energy supplier and sign the supply contract. From this moment, your house is officially connected and you have power.

The usual total timeframe is 6-12 weeks, depending on the operator’s workload and the complexity of the connection solution.

Single-phase or three-phase for a new house?

The choice between single-phase and three-phase depends on consumption:

• Single-phase is sufficient for an ordinary home, with standard appliances and approved power usually up to 11-13 kW.
• Three-phase becomes necessary if you have a heat pump, an EV charging station, air conditioning across several rooms, a workshop or high-power equipment. Three-phase also provides a more balanced distribution of the load.

If you are not sure what power you need, use the connection cost calculator or ask us for an assessment.

Common mistakes to avoid

• Submitting an incomplete dossier – delays the issuing of the ATR by entire weeks.
• Underestimating the power – if you request too little now, you will face additional costs for a new connection at a higher power.
• Not having the DIU in time – without the DIU, the meter is not installed, even if the connection is ready.
• Choosing a company that is not ANRE-certified – the designs and the works must be carried out by a certified company, otherwise the operator will not accept the work.

Why choose SUN WATT for connecting your house

• ANRE-certified for building and designing electrical connections;
• coverage in Bucharest, Ilfov and Giurgiu;
• national DIU, so a valid dossier regardless of the operator;
• transparent, indicative prices, with the final cost correctly set through the ATR.

Conclusion

Connecting a new house to electricity is a process in 5 steps: the connection dossier, the ATR, the connection design and works, the DIU and, finally, the meter plus the supply contract. With an ANRE-certified company that takes over the entire process for you, you avoid delays and get power to your new house sooner. Prices start from 1,800 lei for single-phase and 2,900 lei for three-phase, while the final cost is confirmed through the ATR.
