A switch may be defective
Protection that fits your installation.
If an RCD (safety switch) may be defective or the fuse box is being changed, an electrician can assess the appropriate replacement and checks after installation.
- Reason for replacement
- Suitable device and configuration
- Checks after installation
An enquiry is not a confirmed appointment. We discuss the work and costs first.

When might you need this service?
You do not need to diagnose the installation yourself.
Protection needs to be updated
Work is planned on the fuse box
Understand the work before you agree.
Find out what is actually wrong
An RCD that trips is not necessarily defective. A fault in an appliance or circuit can still make a newly installed device trip.
Match the device to the installation
The type and configuration must suit the existing installation. Discuss the required power interruption and checks after the work.
Plan the interruption and access
In Dutch homes, the consumer unit is called a groepenkast and is often in the meter cupboard. Tell us if the cupboard is shared, if essential equipment must stay powered, and which new appliances you plan to use.
Work on the network connection or sealed meter may involve your grid operator; describe the existing setup so responsibilities can be clarified.
Describe the job in plain English.
Tell us what you see, where the work is and how we can reach you. You do not need to choose a technical solution before contacting us.

In a rented home or apartment?
Tell your landlord or property manager about a fault and check who can approve changes to fixed wiring. Mention access to a shared meter room or parking area where relevant.
Find your townAsk for the full cost before work starts.
The price depends on the fault or installation, materials, labour and timing. Describe your situation so we can discuss the relevant charges before you confirm a visit.
How costs are discussedVisit and diagnosis
Ask about a call-out charge and fault finding.
Labour, materials and VAT
Ask for the expected total, including applicable VAT.
Urgent or additional work
Check possible evening or weekend charges, and agree to extra work first.
For this particular job
Assessment, suitable material and installation determine the cost. Repairing a separate fault is additional work.
Send the job detailsQuestions about rcd replacement.
You can call if your situation is different.
Will replacing the RCD fix repeated trips?
Only if assessment shows the device needs replacing. A fault elsewhere in the installation could remain.
Do I need to know what caused the problem?
No. Tell us what stopped working, when it started and whether it affects a room or the entire property. Do not open the fuse box or try to repair exposed wiring yourself.
Is my online request a confirmed booking?
No. We contact you to discuss the job, expected timing, availability and costs. An appointment is confirmed only after you agree.
I rent my apartment. Who should I contact?
You can describe the problem to us, but also tell your landlord or property manager. For work in shared parts of a building, access and permission may need to be arranged.
