Steps to install electrical wiring in your home
The average cost of doing electrical installation in a home will vary depending on the size of the property and the number of light points and outlets. On average, in a 90 m² apartment it can be around 2,000 €, while in a 120 m² home it could approach 3,000 €.
1. Get quotes from several electricians
Contact at least three electricians specializing in residential electrical installations to get comparative quotes. Prices vary significantly based on complexity, ranging from 2,200 € to 9,000 €, with an average of 5,300 €. Request details about materials, timelines, and warranty to make an informed decision.
2. Assess the current state of the installation
The electrician must inspect the existing electrical installation to identify deficiencies, deteriorated wiring, or insufficient capacity. This evaluation determines whether you need a complete installation or just an expansion, directly affecting the final budget. A complete single-family home installation may cost between 2,000 € and 5,500 € depending on its condition.
3. Determine the necessary lighting points and outlets
Plan the quantity and location of light outlets and power sockets based on your comfort and safety needs in each room. Modern building codes require proper distribution to avoid overload. Your budget may increase significantly if you substantially expand the number of connection points.
4. Design the electrical plan with the professional
Work with the electrician to create a detailed plan specifying circuits, protections, wire gauges, and general distribution. This document is essential for obtaining municipal permits and ensuring a safe, code-compliant installation. A well-designed plan prevents additional costs and future repairs.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Home size and square footage
The number of square meters determines the amount of wiring, piping, and connection points needed. A larger home requires more materials and labor time, significantly increasing the final budget.
Number of light fixtures and outlets
Each light fixture, outlet, and switch adds to the installation cost. Modern homes require more independent circuits than older ones, which directly impacts the total price.
Installation type: new or retrofit
A new installation during construction is cheaper than a retrofit in an occupied home, where walls must be broken, conduits installed, and repairs made afterward. Retrofits can cost 30-50% more than new construction installations.
Technical complexity and regulations
If the home requires a more powerful electrical panel, reinforced grounding, or compliance with special regulations (such as sustainable homes), the cost increases. Access to the main distribution box also plays a role.
Factors that influence the cost of electrical installation in a house
The average cost of doing electrical installation in a home will vary depending on the size of the property and the number of light points and outlets. On average, in a 90 m² apartment it can be around 2,000 €, while in a 120 m² home it could approach 3,000 €.
The cost of electrical installation in a home will depend on several factors such as the size of the property and the elements that make up the installation.
Regulations for new electrical installations according to REBT
The average cost of doing electrical installation in a home will vary depending on the size of the property and the number of light points and outlets. On average, in a 90 m² apartment it can be around 2,000 €, while in a 120 m² home it could approach 3,000 €.
Factors that affect the price
In the case of weatherproof boxes, necessary to protect electrical connections outdoors, prices vary depending on the type and associated elements:
- The distribution panel with automatic general switch, differential switch, and surge limiter starts from 300 €.
- A two-unit multi-purpose outlet circuit costs from 130 € onwards.
- The kitchen circuit, including oven, cooktop, dishwasher, and washing machine adds at least another 150 € to the budget. The circuit for the refrigerator or water heater will add between 30 € and 60 € more.
- An air conditioning circuit for two units starts from 150 €.
It is the Low Voltage Electrotechnical Regulations (REBT) that establishes all the requirements that a new electrical installation must meet. This regulation does not only refer to residential properties, but regulates all types of electrical installations in shops, garages, swimming pools, outdoor lighting, and even operating rooms.
In general terms it establishes the following:
- Service connections: only personnel from electrical companies or authorized installers are qualified to handle them or perform work on them.
- Light panel: should be as close as possible to the entry of the main branch, near the house's access door and at a height between one and a half and two meters from the ground.
- Lines and branches: must have an automatic switch that can be operated manually. The so-called PIAs protect against short circuits and overloads.
- Conductors and conduits: The REBT leaves nothing to improvisation and specifies from the diameter of the conduits to the colors of the different cables according to their function. Conductors must be made of copper.
