What actually happens

The four measurements: what a real NEN 1010 inspection consists of.

There are companies that come “have a look” for a hundred euros and then stick a label. That is not an inspection. A NEN 1010 inspection consists of a visual check plus four measurements with a calibrated installation tester, and those measured values belong on your report.

1 · Insulation resistance per circuit

Insulation resistance

We measure per circuit whether the cable insulation is still intact, with a 500 V test voltage. A low reading means moisture or damage somewhere — often long before you notice anything. The limit is 1 MΩ; we record the actual value, not just “pass”.

limit> 1 MΩ

2 · Earth electrode resistance

Earth electrode resistance

How well your earthing actually makes contact with the ground. In Amsterdam with its wet subsoil usually favourable, but in buildings where the earth electrode has rusted through or was never installed, we regularly measure values that fail.

guide value< 166 Ω

3 · RCD trip time

RCD trip time

Not whether it trips, but how fast. We inject a leakage current and measure the time in milliseconds. At 30 mA it must trip within 300 ms; in practice we see older RCDs with times that are double — it still works, but no longer in time.

limit< 300 ms

4 · Continuity and loop impedance

Continuity & loop impedance

We check whether the earth actually runs through to the last socket, and measure the short-circuit current to determine whether the MCB trips fast enough on a fault. This is the measurement that brings loose terminals and forgotten earth conductors to light.

Visual inspection

Live terminals checked, cable sizes checked against MCB ratings, bathroom zones remeasured, meter cupboard chart compared with reality and the presence of interlinked smoke detectors verified.

Option · Thermography

Thermal imaging

A thermal image of the fuse box under load. A loose terminal shows on the photo as a hotspot, long before a scorch mark or burning smell appears. For VvEs and landlords we recommend this as standard.

What you actually need it for

The report itself, and who actually asks for it.

The measurements take a morning. The document you have afterwards lasts for years. Four parties ask for it, each for their own reason.

Your insurer

After fire or water damage involving electrics, the first question from a loss adjuster is who installed the system and whether it was inspected. A signed report with measured values and a date is then the difference between a payout and a discussion that lasts months. This is by far the most important reason to have one, and why it is a waste to only think of it once something has already gone wrong.

Your buyer

When selling a home from before 1990, a well-prepared buyer asks about the state of the electrics. Without a report that becomes a negotiation point where a few thousand euros easily come off “to be safe”. With a report it is a ticked box. For € 295 that is almost always the cheapest insurance in the whole sales process.

Your VvE

If you want work that touches the shared installation — a charging point in the garage, a heavier supply, an adaptation in a shared meter cupboard — the VvE wants to know it will be done safely. An inspection report plus drawing is usually enough to get that permission through.

Yourself, if you let out

As a landlord you have a duty of care for the safety of the installation. If something happens and you cannot show you took that duty seriously, it becomes a problem — legally and for insurance. An inspection per home and a maintenance contract is how you make that demonstrable.

What is in our report
  • Address, date, name and signature of the inspector
  • Overview of the installation: supply rating, number of circuits, type of protection
  • Measured values per circuit, with the limit alongside
  • Trip time of every RCD in milliseconds
  • Findings, graded by urgency: immediate, in time, attention point
  • Photos of every defect we find
  • An indicative price per remedial item, without obligation
  • Meter cupboard chart, updated to the actual situation

You receive the report as a PDF within two working days, in English if you prefer. You may take it anywhere; there is no obligation to have remedial work done by us.

We also inspect without follow-on work

An inspection where the inspector knows they may do the remedial work themselves is not an independent inspection. We deliver the report and leave you free: if you take it to another party, that is fine. That is exactly why the report is worth something.

Which inspection fits you

NEN 1010, NEN 3140 or a completion inspection — which one applies to you.

The names are used interchangeably, including by installers. In short: NEN 1010 covers how an installation must be built; NEN 3140 covers how an existing installation in a work environment is kept safe.

What an inspection is not

An inspection is not a guarantee that nothing will ever go wrong, and it is not a building survey. We measure what is measurable at the moment of inspection, on the installation as it then stands. What sits behind a plastered-over wall and is not accessible we cannot assess visually — we then state that explicitly in the report instead of leaving it out.

The question that holds people back

What happens if something fails the inspection.

This is why people put an inspection off: the fear that a list comes out costing thousands of euros. In practice it is milder than that, and more importantly: you are not tied to anything.

There is no “fail”

A home installation is not failed the way a car is at an MOT. There is no authority that cuts your power. We record findings and grade them by urgency, and you decide yourself what to do with them. That is your property and your call.

Three categories of findings

  • Immediate — an acute safety risk: an exposed core, a missing RCD at wet rooms, an overheated terminal. We can resolve this the same day if you wish.
  • In time — it works now, but it will fail at some point or no longer meets the current standard. For example one RCD for the whole home, or too few circuits for your equipment.
  • Attention point — not a problem, but good to know. A meter cupboard chart that does not match, a circuit that feeds two rooms, a junction box that is hard to reach.

What it usually turns out to be

In homes from before 1980 that have never been updated, the same list often comes out: no or one RCD, missing earth pin in kitchen or bathroom, and too few circuits. Together that is usually a new fuse box with earthing — between € 1,170 and € 1,900. In installations after 1995 we typically find nothing that must be done immediately.

Re-inspection

If you have the remedial work done by us, the re-inspection is in the price and you get an updated report at no extra cost. If you have it done by someone else, we come back if you wish for € 145 to remeasure only the remedied points.

What we find most often
One or no RCD62%
Earth pin missing somewhere48%

Loose terminal in the fuse box18%
Acute danger, must be immediate6%

Indication based on our own inspections in Amsterdam homes from before 1990. Replace these figures with your own records once you have done enough inspections — own data persuades more strongly than an average.

Remedial work usually costs less than feared

The two line items that most often come out of an inspection are a new fuse box (from € 745) and installing earthing (from € 425). Together well under two thousand euros, and with that the installation is sound for the coming decades.

All amounts include 21% VAT, valid in 2026 for Amsterdam and surrounding area. An inspection as a service falls under the general VAT rate; the reduced 9% rate applies only to the labour element of insulating, plastering, painting and wallpapering in homes older than two years.

Frequently asked questions

Frequently asked questions.

What does a NEN 1010 inspection of a home cost?

An inspection of a home installation costs € 295 including 21% VAT. That covers travel within Amsterdam, the visual inspection, the four measurements, the signed report with all measured values, an updated meter cupboard chart and a telephone explanation afterwards.

A completion inspection after a renovation costs € 345 because that includes a full test protocol per circuit. A NEN 3140 inspection for a commercial space or a VvE starts at € 425 and depends on the size of the installation. If you have multiple homes, a fifteen percent discount applies from five units.

Is an electrical inspection legally required?

For an ordinary home, no. There is no MOT for electrics and nobody cuts your power. In practice an insurer does ask for it after damage, a buyer asks for it on sale, and a VvE asks for it before approving work on the shared installation.

It is required in workplaces: Dutch health and safety law (Arbowet) requires a periodic NEN 3140 inspection, usually every three to five years. That also applies to common areas of a VvE where work takes place. And a new or substantially altered installation always requires a completion inspection to NEN 1010.

What exactly is measured?

Four measurements with a calibrated installation tester. Insulation resistance per circuit, measured at 500 V test voltage, must be above 1 MΩ. Earth electrode resistance shows how well your earthing contacts the ground. The trip time of every RCD is measured in milliseconds and must stay under 300 ms at 30 mA. And continuity and loop impedance show whether the earth runs through everywhere and whether an MCB trips fast enough on a fault.

On top of that comes a visual inspection: terminals, cable sizes against MCB ratings, bathroom zones, the meter cupboard chart and the presence of interlinked smoke detectors. All measured values go on the report — not only the conclusion ‘pass’.

How long does it take and do I need to be there?

Two to three hours for a home, three to four hours for a completion inspection. You do not need to stay, provided we can reach the meter cupboard and the rooms. Helpful: let us know where the bath, washing machine and any outbuildings are.

During the measurements power comes off the circuits briefly several times. If you have equipment that must not switch off, say so beforehand and we plan around it. You receive the report as a PDF within two working days.

What happens if something is not in order?

Nothing compulsory. There is no authority that intervenes and we do not stick a label. We record our findings and grade them by urgency: immediate, in time, or attention point. At each point we put a photo and a non-binding price indication, so you can decide yourself what to do.

What typically comes out of older Amsterdam homes is the same list: no or one RCD, missing earth pin in kitchen or bathroom, and too few circuits. The remedial work is then usually a new fuse box with earthing, together between € 1,170 and € 1,900. In installations after 1995 we usually find nothing that must be done immediately.

Am I tied to remedial work by you after the inspection?

No, and that is a principle. An inspection where the inspector knows they may do the remedial work themselves is not an independent inspection. You get the report and you are free: if you take it to another company, that is fine.

If you do have the remedial work done by us, the re-inspection is in the price and you get an updated report free of charge. If you have it done by someone else and still want us to remeasure, we come back for € 145.

What is the difference between NEN 1010 and NEN 3140?

NEN 1010 covers how a low-voltage installation must be built: cable sizes, circuit layout, RCD protection, bathroom zones. A NEN 1010 inspection tests an existing or new installation against that standard. That is the inspection for homes.

NEN 3140 covers the safe use and maintenance of an existing installation in an environment where people work. That inspection is periodic — usually every three to five years — and required under health and safety law. For commercial spaces, shared VvE areas and rental properties that is the right inspection.

I am selling my home — is an inspection worth it?

For a home from before 1990, almost always. A well-prepared buyer asks about the state of the electrics, and without a report that becomes a negotiation point where a few thousand euros easily come off ‘to be safe’. With a report in the sales pack it is a ticked box.

For € 295 that is almost always the cheapest insurance in the whole sales process. If something comes out that needs fixing, you also know that before viewings rather than during negotiation.

Do you provide inspection reports in English?

Yes, at no extra charge. A NEN 1010 inspection of a home costs € 295 including 21% VAT and the signed report — with all measured values, findings graded by urgency, photographs and an indicative repair cost per item — can be supplied in English.

The four measurements are insulation resistance per circuit at 500 V, earth electrode resistance, RCD trip time in milliseconds, and continuity and loop impedance. Inspection takes two to three hours on site and you receive the report as a PDF within two working days. There is no obligation to have any remedial work carried out by us.

Is an inspection charged at 21% VAT or 9%?

21%. An inspection is a service and falls under the general VAT rate. The reduced 9% rate in the Netherlands is reserved for the labour element of insulating, plastering, painting and wallpapering in homes older than two years.

If you are a business, a VAT-liable landlord or a VvE with VAT liability, the VAT is reclaimable for you. Set the switch at the calculator to ‘business’ to see all amounts excluding VAT.
