Buying a Home? Here’s How to Check the Electrical System of the Property
Purchasing a new home is an exciting milestone, but it can also involve significant risks—especially when the property is older and its technical condition is not fully known. One of the most commonly overlooked aspects is the condition of the electrical system. Yet hidden faults or outdated wiring can later lead to serious expenses and safety hazards.
In this article, we’ll show you what to watch out for before buying a home, how a professional electrician’s assessment can help, and when a full rewiring of the property may be necessary—especially in Budapest, where many apartments and buildings are decades old.
Why Is It Important to Inspect the Electrical System Beforehand?
The electrical wiring is hidden behind the walls, so faults or signs of outdated infrastructure are not always visible to the naked eye. However, when moving into a new property, it is essential to ensure that the electrical system:
- is safe (won’t cause fire or electric shock),
- can handle the load of today’s household appliances,
- complies with current standards (e.g. includes a residual current device – RCD).
An old electrical system can be problematic not only from a technical perspective, but also from an insurance standpoint if any malfunctions occur later.
When Can the Electrical System Be a Problem?
When buying a property, look out for the following warning signs:
- Aluminum wiring: Common in apartments built in the 1970s and 1980s. These wires are now aged, fragile, and often unable to handle modern electrical loads.
- No RCD (residual current device): Older distribution boards may lack this critical safety feature that protects against electric shock.
- Too few outlets, many extension cords: Not only inconvenient, but it can also lead to overloaded circuits.
- Frequent tripping of circuit breakers: This may indicate hidden faults or an undersized electrical system.
What Does a Preliminary Electrical Inspection Include?
During an on-site assessment, a qualified electrician will:
- Inspect the distribution board, wiring, outlets, and switches.
- Determine how well the electrical system complies with current regulations.
- Use specialized instruments to check the condition of the wiring and grounding.
- Provide a written recommendation regarding any necessary repairs or replacements.
- If needed, offer a cost estimate for a full electrical system upgrade.
Important to know: The inspection and planning process requires expertise and time, so it is perfectly reasonable for this to be charged as a standalone professional service.
How Much Does an Inspection Cost? – An Important Distinction
In electrical work, there are two types of inspections, each with a different purpose and legal significance:
Basic Electrician Assessment (30,000 HUF)
This is an on-site consultation based on visual inspection and instrumental testing. The electrician checks the distribution board, assesses the condition of the wiring, and tests the function of outlets and switches.
You receive a verbal or brief written recommendation on any necessary actions.
This is not an official document, but it serves as an excellent point of reference when buying a property or planning a renovation.
Electrical Safety Inspection (~1,000 HUF/m², minimum 50,000 HUF)
This is an official, documented procedure. The goal is to determine whether the existing electrical system meets current standards and safety regulations.
At the end of the process, you receive a detailed written report (certificate), which may be required for property rental, insurance claims, or official inspections.
How Much Does a Full Electrical Renovation Cost?
If the inspection reveals that the wiring needs replacement, a complete overhaul of the electrical system is recommended. The cost depends on:
- the size of the property,
- the number of circuits,
- the quality of materials used,
- and the amount of demolition/chiseling work required.
The estimated cost of such a renovation can range from several hundred thousand to several million forints. In every case, a custom quote is necessary.
Why Is It Important to Conduct the Inspection Before Signing the Purchase Agreement?
Many buyers only realize after taking possession that the property needs more extensive renovations than expected—including the electrical system. This can lead to significant unexpected costs with a newly purchased home.
A timely professional electrician’s assessment can help:
- provide leverage in price negotiations with the seller,
- prevent unexpected expenses,
- and support a confident, well-informed buying decision.
