Quick answer
In short
Replacing an RCD costs on average €90 to €200 including materials and fitting. An individual RCD (type A, 30 mA) costs €30 to €90 in materials, a type B for an EV charger, for example, more. Adding an RCD to an older box costs €120 to €250. If the RCD keeps tripping, have the fault traced first (from €89).

Prices by situation
Prices at a glance
Price by situation
What you pay depends mainly on whether we replace a faulty RCD, add one to an older box, or first need to trace a fault. These are guide prices including fitting and connection to the NEN 1010 standard.
| Situation | What it involves | Price incl. fitting |
|---|---|---|
| Replace faulty RCD (type A) | Old one out, new one in, testing | € 90 to € 200 |
| Add an RCD to an existing box | Extra protection, provided there is room | € 120 to € 250 |
| Replace type A with type B | Heavier protection, e.g. for an EV charger | € 150 to € 280 |
| Fit an RCBO | RCD and fuse for one circuit in a single component | € 90 to € 200 |
| RCD trips: trace the fault | Find the cause before replacing | from € 89 |

Price breakdown
What determines the price of an RCD?
No two meter cabinets are the same. Together these points determine what the work costs. That way you understand where your price comes from.
Replacing or adding
Replacing a faulty RCD is a short job. Adding one to an older box requires more work and sometimes extra room, which adds up.
Type A or type B
A type A (30 mA) is enough for ordinary circuits. Some EV chargers require a type B, depending on the charger (many modern wallboxes already have the right protection built in). Type B is considerably more expensive.
Room in the meter cabinet
If the box is full or old, adding is tricky. Sometimes a new fuse box is then more sensible than keeping on adding to an outdated box.
Whether or not to trace a fault
If the RCD keeps tripping, the switch is not faulty; there is an earth leakage in the installation. Tracing the cause first is separate work.
Access to the box
A cramped or boxed-in meter cabinet takes more time. The location (cellar, loft, cabinet in the hallway) also plays a part.
Emergency or planned
Planned work is better value. If you are without power and it needs doing urgently, an emergency surcharge may apply.
Worked examples
Worked examples from practice
To give a feel for the price, here are three situations of the kind we often come across in Brabant. You always get your price upfront, fixed and tailored.
Replacing a faulty RCD
In a terraced house the RCD no longer responds to the test button. The switch itself is worn out and needs replacing. The rest of the box is perfectly fine.
- RCD type A, 30 mA€ 65
- Labour: replace and test€ 75
- Call-out charge€ 39
A short job, neatly done in an hour, RCD tested with the test button and a measurement.
Adding an RCD to an old box
A 1980s home with just one RCD for the whole installation. The residents want the protection sorted, with a second RCD so not everything cuts out at once.
- RCD type A, 30 mA€ 70
- Labour: split circuits and connect€ 130
- Call-out charge€ 39
There was just enough room in the box. Had it been full, we would have advised a new fuse box.
RCD keeps tripping: trace the fault
The RCD keeps flipping. The switch is not faulty; somewhere in the installation current is leaking away. We trace the cause first and then replace whatever is needed.
- Fault tracing (earth leakage)€ 89
- Replace RCD (materials + labour)€ 120
- Call-out charge€ 39
The cause turned out to be a damp outdoor circuit. We disconnected it and replaced the RCD. For urgent faults: call our breakdown service.
Good to know
Good to know about RCDs
RCDs are your home's safety protection. They protect you against an electric shock that can be life-threatening. This will help you understand the choices and the price better.
RCD or RCBO?
An RCD usually protects several circuits at once. If it detects current leaking away (for example through a shock or damp), it switches everything off within a fraction of a second.
An RCBO combines that earth leakage protection with the fuse for one circuit in a single component. Handy if there is little room in the box or if you want to protect per circuit. An RCBO is more expensive per unit, but you sometimes need fewer of them. What is smartest in your box we assess on the spot.
30 mA: personal protection
The 30 mA marking means the switch cuts out as soon as more than 30 milliamps leaks away. That is the limit your body can still safely handle. So this 30 mA is genuine personal protection: it is there to prevent an electric shock from harming you.
Under NEN 1010 a modern fuse box has at least two 30 mA RCDs. That way a fault does not cut out your whole house, only the part that is protected. If you have only one, upgrading is often sensible.
Type A or type B
A type A is the standard and covers most situations in the home: lighting, sockets, household appliances. For an ordinary home this is the right type.
A type B is heavier and also detects DC leakage currents. You need it for appliances with certain electronics, such as some EV chargers for electric cars. Many modern EV chargers already have that detection built in, in which case a type A is enough. A type B is considerably more expensive (from €100 in materials, often more). If you are connecting an EV charger, we advise the right type straight away, so it is done properly and safely in one go.
VAT and what is in the price
All prices on this page are including 21% VAT and including fitting. For replacing or adding an RCD in an existing home the normal VAT rate of 21% applies.
Our quote always states a fixed price: materials, labour, the call-out charge and the test together. No after-the-fact billing, no surprises. Only if something unexpected turns up during the work, for example an earth leakage deeper in the installation, do we discuss it with you first before we continue.
Smart savings
Smart ways to save on your RCD
Without compromising on safety, there are a few sensible ways to manage the costs.
Combine the work
Is an engineer coming round anyway for an extra circuit, EV charger or maintenance on the box? Then have the RCD checked or dealt with at the same time. One journey saves money.
Weigh replacement against a new box
If your box is old and full, adding to it is often more expensive than it seems. Sometimes a new fuse box is cheaper and safer in the long run. We work it out honestly for you.
Do not wait for a fault
Does the test button no longer respond, or does the RCD keep tripping? Have it checked in a planned visit. That is better value than an emergency job when you are without power.
