FAQ

Frequently Asked Questions

What exactly does a licensed electrical contractor do?

What does it mean to be "recognized"?

Recognition by InstallQ or a similar body demonstrates that we are demonstrably competent, are periodically inspected, and work in accordance with national safety standards. This gives you certainty about quality and safety.

Should my electrical system be inspected periodically?

Periodic inspection is recommended and mandatory for companies and homeowners' associations under the Working Conditions Act. A NEN 3140 inspection prevents risks of fire or injury and demonstrates that your installation is safe to use.

When is my distribution board due for replacement?

The expected lifespan of a distribution box depends greatly on the type of components, the load, and maintenance. Signs include blown fuses, missing earth leakage circuit breakers, insufficient groups for modern consumers (induction, heat pump, charging station), and outdated or unclear wiring. We are happy to assess this on site.

Can I expand a group or add an outlet myself?

You can sometimes do minor work yourself, but expansions to the distribution board, new pipes or extra terminal groups should be performed by a licensed installer. This keeps your installation safe and insurance covered.

I want to increase the size of my distribution board, how does that work?

If you wish to upgrade your connection, we will first assess your current installation. This is done by means of an on-site inspection or, if possible, on the basis of clear photos of the distribution box and main connection.

If upgrading is technically feasible, we will carry out the necessary work, such as installing a 4-pole main switch and modifying the internal wiring. You must then submit the official application for upgrading the grid connection to your grid operator via mijnaansluiting.nl

We can, of course, assist you with this application and indicate which specifications are required .

I want to switch from 1-phase to 3-phase, what will change in my distribution board?

When switching from single-phase to three-phase (400 V), we first assess whether your fuse box and cabling are suitable for this. Often, an on-site inspection or assessment based on clear photos is sufficient to determine this.

During the conversion, we install a 4-pole main switch with a temporary loop and adjust the internal distribution so that the load is evenly distributed across the three phases. If necessary, we replace the distributor, fuse holders, or add components such as earth leakage switches or circuit breakers.

You then request the actual upgrade of the grid connection yourself from your grid operator via mijnaansluiting.nl
During the grid operator's visit, the single-phase smart meter will be replaced with a three-phase version and connected to the 4-pole main switch. The temporary loop will be removed at this point.

Do you perform inspections according to NEN 3140 or NEN 1010?

Yes. We provide completion inspections (NEN 1010) and periodic inspections (NEN 3140), including a measurement report and, if desired, a declaration of conformity.

Do you provide breakdown or emergency service?

Yes, within our region we fix urgent breakdowns as soon as possible. VvEs and customers with maintenance appointments are given priority. Outside office hours by appointment.

What are the benefits of LED lighting?

LEDs consume up to 80% less energy, last longer, and require little maintenance. They combine well with presence sensors and smart switches for additional savings. Furthermore, incandescent bulbs, halogen bulbs, energy-saving bulbs, and fluorescent bulbs have been phased out gradually since 2012.

Can my installation be expanded to include solar panels or a charging point?

We usually do. We first assess the capacity of your installation. Sometimes an increase in the main connection or modification of the distribution board is necessary for a safe expansion.

What does phase distribution or load per phase mean?

With a 3-phase connection (400 V), power is distributed to three phases. Proper distribution prevents overloading and outages. We check this when installing solar panels, heat pumps and charging stations.

Do you also install home charging points or for CoEs?

Yes. We supply and install charge points for private and business customers, including load-balancing, meter box adjustment and inspection. For VvEs we also arrange the technical preparation and management arrangements. More information can be found on our services page on electric charging

Do you also work for VvEs, companies and property managers?

Yes. We offer scheduled maintenance, NEN inspections, emergency lighting and priority breakdown monitoring. See also ourVvE & Property Managementpage.

What guarantee do you give on work?

Far, far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated, they live in Bookmark Grove right on the coast of Semantics, a large language ocean.

Do you also do small work (connect lamp, extra outlet)?

Yes, you can also come to us for small jobs. You can then be sure that everything is connected safely and correctly.

Are you working with smart systems or home automation?

Yes. We install Jung Home, KNX components, smart thermostats, Home Assistant connections and energy management, among other things. So we link lighting, heating, PV and charging stations.

What are your working area and region?

We work primarily in Zuidplas and surrounding areas: Zevenhuizen, Waddinxveen, Moerkapelle, Moordrecht, Nieuwerkerk a/d IJssel, Capelle a/d IJssel, Rotterdam and Gouda. Outside the region on request.

What does an installer cost per hour?

Our current hourly rate is €75.95 excluding VAT (€91.90 including VAT). We charge per ten-minute time unit and clearly communicate any material costs. See also our page about our rates.

Do you charge a call-out fee?

Yes, our call-out fee within our primary working area, also known as the starting rate, is €39.00 excluding VAT (€47.19 including VAT) per visit. This amount will remain unchanged in 2026. Outside this area, travel costs will be calculated based on mileage and travel time. See also our page about our rates.

How do I request a quote?

Via the contact form, by email or by phone. We first discuss your needs; for larger projects, we will schedule an on-site shoot and you will receive a clear quote.

Will I receive a declaration of conformity after completion?

Yes, if required we can provide a declaration of conformity according to NEN 1010/NEN 3140. This proves that the work has been carried out by a recognized installer.

Can you help with emergency lighting and annual testing?

Yes. We test, maintain and replace emergency lighting and record the results for your records and any audits.

Is my electrical installation suitable for a heat pump, solar panels, and a charging station?

Many homes and commercial buildings have electrical installations that were originally designed for lower power consumption. Modern applications such as heat pumps, solar panels, charging stations for electric cars, and home batteries require sufficient capacity, correct phase distribution, and a safe, standard-compliant distribution box.

During an inspection, we assess, among other things:

  • whether your connection is single-phase or three-phase,
  • the tax per phase,
  • the technical condition and expandability of the distribution box,
  • the presence and operation of earth leakage circuit breakers,
  • whether the installation complies with NEN 1010 and NEN 3140.

Based on this, you will receive clear advice on whether your electrical installation is suitable and future-proof, or whether adjustments such as replacing the fuse box, phase redistribution, or upgrading the grid connection are necessary.
