For homes to NEN 1010 and for businesses to NEN 3140. A clear report, honest advice and careful work: your safety and your obligations in order.

NEN 1010 inspection for your home
Ready for your insurer when buying a home, renovating or upgrading the installation.
A NEN 1010 inspection shows the condition of your electrical installation. I don't just identify problems, I turn them into concrete actions. For serious findings I can schedule follow-up work straight away (replacing the consumer unit, adding RCD protection, renewing faulty cabling).
- When buying or selling a home
- For insurance (some insurers require it)
- After a major renovation or extension of the installation
- If you have doubts about the safety of an old installation
- For homes older than 25 years: strongly recommended
NEN 3140 for your business
A legal requirement for employers: work equipment and fixed installation.
- Inventory of all work equipment
- Visual check and measurement per appliance
- Sticker or label for each inspected appliance
- Digital report with findings
- Distinction between approved, conditional and rejected
- Photo evidence of defects
- Advice on rejected appliances and re-inspection after repair
What do I look at specifically?
Concrete points of attention, tailored to your situation.
Consumer unit and distribution board
I check fuses, earth fault protection, cable routing and visible connections. Faulty circuit breakers, a missing RCD or an incorrect circuit layout are an immediate red flag.
Capacity and load
Do the main protection and the circuit layout match the use (EV charger, cooking, machinery and so on)? Overloading is a fire risk.
Documentation
Do diagrams and measurements (where available) match the situation on site? Newer installations must have documentation.
Classification of findings
I classify findings (repair needed straight away, or an improvement for later) and discuss the options with you, without technical jargon.
How does an inspection go?
From first contact to report in 5 steps.
- Intake: by phone or via the form. I discuss the type of building, the purpose of the inspection and the number of work appliances (business) or floor area (home).
- Quote within 1 working day, based on the scope. The amount is a guide price.
- Inspection on site: for homes 2 to 4 hours for an average house. For businesses it depends on the number of work appliances and the fixed installation.
- Reporting: within 2 working days a digital report in your customer portal, with photos, findings, priorities and advice.
- Follow-up: if defects are found, a no-obligation quote for the repair. You decide whether you choose me or arrange it yourself.
When letting or selling property
- A NEN 1010 inspection shows a modern, safe condition and increases the buyer's confidence
- Proves your duty of care when letting
- Findings before the sale give you the chance to repair without pressure
- Sometimes required by the mortgage lender or valuer
- Final report only after any repairs
Questions about the inspection
What is the difference between NEN 1010 and NEN 3140?
NEN 1010 is for the fixed electrical installation of a building, applied in new builds, renovations and home inspections. NEN 3140 is for the periodic inspection of work equipment and the fixed installation of businesses, a legal requirement for employers.
How long does an inspection take?
Home: usually 2 to 4 hours, depending on the size. Business: it varies, a small office 4 to 8 hours, a large production site several days. I give you an estimate up front.
Do I get a report straight away?
I give you verbal feedback on urgent findings straight away. You receive the full digital report within 2 working days in your customer portal.
What if problems are found?
I classify findings (urgent, recommended, cosmetic) and give advice. You get a no-obligation quote for the repair and you decide whether you choose me or arrange it yourself. No pressure.
How often is a NEN 3140 inspection needed?
It depends on use: construction site equipment every six months, normal office equipment every 3 to 4 years. Fixed installation usually once every 4 years. More often with intensive use. I advise the right frequency per appliance.
Does every appliance get a sticker?
Yes, with NEN 3140 I put a sticker on each appliance with the inspection date and the status (green is approved, orange conditional, red rejected). That makes audits easy.
Will my home fail if there are defects?
NEN 1010 has no pass or fail the way NEN 3140 does for work equipment. I report the findings and the risk class. For serious defects I advise immediate action.
Does the inspection also cover EV chargers and solar panels?
Yes, EV chargers fall under NEN 1010 (fixed installation) or NEN 3140 (business). Solar panels and the inverter are included too. I check that the installation, the protection and the connection to the consumer unit are in order.

From my knowledge base, in plain language.
Electrical inspection when selling or buying a home
An inspection is not compulsory when selling, but the report prevents discussion and surprises after the keys are handed over.
3 min readSurge protection: necessary or nonsense
A surge protector catches the spike that would otherwise wreck your equipment. With solar panels, an EV charger or a detached house it is worth it.
3 min readEarthing: why it is there and how you know whether it is sound
Earthing is the path a fault runs away along so the protection can work. Without a sound earth, the rest does not work.
