What customers say about Joulo
4.8 (205 ratings) on the App Store & Google Play·12,000+ app users • most-used ERE registration appExcellent advice through the app, thanks to Johan
I asked for advice through the app and Johan helped and advised me excellently.
Very good experiences with Joulo
My questions were answered super fast via WhatsApp, on a Sunday. Quickly scheduled a new Tesla charger with MID meter, professionally installed by Ruben. Signing up was a piece of cake with the well-designed app. Flawless so far, highly recommended!
Loads of support for all kinds of chargers, and great service
Another provider couldn't connect to my EVBox Elvi MID. After some messaging back and forth with Joulo I was connected: my EVBox now talks to an OCPP proxy, so I can control it with Home Assistant while the charging data flows to Joulo automatically for ERE registration.
Joulo's support is excellent!
I just couldn't get my charger to connect, so I called in Joulo support. The agent took all the configuration off my hands and within 15 minutes the system was up and running. Top service.
Top service!
After some research I chose Joulo, and so far without regret. Great service and very quick responses to a few questions. The app is clear and pleasant to use.
Excellent experiences with Joulo
Technically the most mature: strong automation, real-time insight and support for standards like OCPP. Their accessibility and technical openness are well above average and very professional.

// Healthy skepticism
Sounds too good to be true?
Fair reaction. So here is exactly where the money comes from • and how you can verify every sale yourself.
Where the money comes from
Fuel suppliers are legally required to reduce the CO₂ emissions of transport. They do this by buying EREs: proof of avoided CO₂. Every kWh you charge at home instead of refuelling delivers that saving • which makes it worth money.
Why through Joulo
The NEa sets requirements for registering parties that an individual household cannot meet. Joulo B.V. is on the official NEa list of registered ERE service providers and bundles your charging sessions with those of thousands of other drivers.
Verify it yourself
