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.
