🏡 Electrical check before buying a property in Spain
Buying a property in Spain? Have the electrical installation checked before you sign.
An electrical installation can look perfectly fine at first glance and still have significant defects. Especially in older properties, installations have often been extended, modified, or partially renewed over many years.
After the purchase, such defects can become expensive — particularly when proper repairs require opening up walls, ceilings, or floors.
I inspect the electrical installation, assess identifiable risks, and explain clearly which defects are actually relevant and what action they may require.
What you can’t see during a viewing
A beautiful property doesn’t automatically mean a good electrical installation
An electrical check before buying a property in Spain allows you to have the technical condition of the electrical installation assessed before making your purchase decision. Colloquially, this kind of inspection is also referred to as an electrical check before buying a house. What matters isn’t the name, but the actual scope of the inspection.
Especially when buying older properties in Tenerife and the Canary Islands, an independent technical assessment of the electrical installation can be worthwhile, since many electrical defects aren’t visible to a buyer.
A new kitchen, nice bathrooms, and freshly painted walls can make an electrical installation look considerably more modern than it actually is.
Problems can occur, for example, in the following areas:
- old or unsuitable cables
- inadequate protection against electric shock
- missing or problematic residual current protection
- unclear or overloaded circuits
- improperly executed later extensions
- problems with earthing and protective conductors
- outdated sub-distribution boards
- missing or unclear documentation
- modifications not carried out to a professional standard
Why the timing of the inspection is crucial
Before the purchase, a defect is something different than after the purchase
Before the purchase, identified defects can factor into your purchase decision.
For example, you can:
- get a better estimate of the cost of any refurbishment
- raise existing defects with the seller
- factor necessary work into the negotiations
- decide whether the property is still of interest to you at all
- plan renovation work correctly right from the start
After the purchase, on the other hand, the problems are yours.
Small defects – big consequences?
Not every electrical defect means a complete overhaul
A defect that’s identified can sometimes be fixed relatively easily.
Other problems, however, can involve considerable effort — for example, when cables need to be completely replaced and, as a result, walls, ceilings, or floors have to be opened up and then repaired.
For a property that’s going to be renovated anyway, this can make a big difference.
That’s why it’s not just important whether a defect exists, but also what consequences fixing it is likely to have.
What is examined during the electrical check?
A technical look at the electrical installation
Depending on the property and the scope of the inspection, the following can be examined and checked, among other things:
- condition of the sub-distribution board
- existing protective measures
- residual current protection
- earthing and protective conductors
- cables and the visible installation method
- circuits and their protection
- sockets and switches
- identifiable later modifications
- surge protection
- condition and plausibility of the existing documentation
- existing Boletín Eléctrico or Certificado de Instalación
This isn’t about examining an entire electrical installation down to the very last detail. Cable runs that aren’t visible obviously can’t be fully assessed without more extensive investigation.
If a photovoltaic system is present, an additional technical assessment of that system may also be worthwhile.
What do you receive after the inspection?
A clear assessment:
🔴 Which defects are safety-relevant?
🟠 Which defects should be fixed soon?
🟡 What isn’t technically ideal, but isn’t an urgent problem for now?
🟢 What appears unremarkable from an electrical engineering point of view?
And — as far as possible based on a visual inspection —:
What measures and effort might be required to fix them?
Especially important for older properties
What has been changed over the years?
Especially in houses and apartments in Spain, the electrical installation was often not completely rebuilt, but rather adapted to new needs over many years.
New air conditioning units, kitchens, electric water heaters, solar power, wallboxes, or other appliances may have been added to an installation that was originally designed for a completely different use.
That’s why the crucial question isn’t just “does everything work?” — but “is the installation still suitable for today’s use?”
An electrical check and a Boletín Eléctrico (Certificado de Instalación) are not the same thing
An existing Boletín Eléctrico doesn’t replace a pre-purchase inspection
An existing Boletín Eléctrico / Certificado de Instalación can provide important information about the installation.
However, it doesn’t automatically mean that today’s installation matches the current requirements of the REBT in every detail, or that all defects are ruled out.
That’s why, before buying a property, what matters is an independent technical assessment of the actual, current condition.
Who is this inspection useful for?
Particularly for buyers of older or renovated properties
An inspection can be especially worthwhile for:
- older houses and apartments
- properties with several phases of renovation
- holiday properties
- villas with extensive building technology
- properties with solar power
- properties with a wallbox
- properties with pool technology
- properties where the electrical documentation is missing or unclear
Thinking about buying a property in Spain?
Have the electrical installation professionally assessed before the purchase.
I’ll show you which defects are actually relevant, where more significant refurbishment costs may arise, and which questions you should ask the seller or estate agent.
