It's understandable to be concerned about the reliability of the charging process for your EV. However, it's important to note that the message you're receiving is likely related to a recent update in UK regulations, and it's not necessarily indicative of a malfunction in your wallbox or your EV.

While it may be frustrating to have to manually override the delay every time you charge your car, it's unlikely that waiting for the regulator to start the charge will cause any harm to your vehicle. The purpose of the delay is to manage demand on the power grid and prevent power outages, which is a priority for the energy industry.

That being said, if you continue to experience issues with starting the charge even after overriding the delay, it may be worth contacting the manufacturer of your wallbox or consulting with a qualified electrician to ensure that there are no technical issues with your charging setup. Additionally, it's always a good idea to keep an eye on any updates or changes to UK regulations related to EV charging, as these can impact your charging experience in the future.
