Construction power meter reading not recorded. Is the incorrect billing correct?

Hello everyone,

I am having some trouble with my construction electricity. We moved into the new house in November last year. Right at the move-in, the construction electricity was switched to "regular electricity" and I got my own meter.

Now I continued to receive invoices for the construction electricity. At first, I suspected that the deregistration of the construction electricity might still take a little time. Now, in March, I found out that the construction electricity was not deregistered, and of course, I did not note the meter reading at the meter change (building my first house!). Apparently, the electrician cheerfully continued to use "my" construction electricity meter in other buildings. Almost 2000 kWh more on the meter than should be there according to calculations!

Is there anything I can do? If it is billed like that, I will probably have to pay hundreds of euros more.

Regards

What does the electrician say about it? Did you build with [GU] or through individual contracts?

Who failed to deregister the meter?
Has it been deregistered now?

Have you paid invoices between November and March?
What does the electrician say?

Intuitively, I would write off the paid money. It went to the electricity company, but from whom should it be legally claimed? You can only lose in court. A partial fault due to missed deregistration, and you remain stuck with all the legal costs.
Dispute all unpaid invoices immediately and prevent new ones from accumulating.

Of course, I pay my bills to the electricity company. Ultimately, it is not their fault. I am registered under meter number 123456 and have consumed the kilowatt hours.

I can only argue logically that, measured against my average monthly consumption, there is way too much recorded for those months. I have nothing more than that.

But I really can only warn everyone to note or photograph the readings of the construction electricity meter. The meter was replaced in my absence (I was on a business trip), I no longer had the opportunity to take a picture, and it got lost in the further construction stress. Now I am stuck and presumably still paying the electricity costs of someone else because someone forgot to deregister that thing. By the way, you cannot deregister it yourself; the electrician has to do that, who also registers it at the beginning. Only he also receives the meters. If you are not careful, you get screwed.

I can only argue purely logically, ...

Depending on who your contracting party is (you apparently don't want to say), one could also argue that there is still 5 or 2 years of warranty on the house / work and that a fair cooperation is expected.

I have a freely designed architect house with self-assigned trades. There won’t be much to gain from the warranty, my electrical work is OK.
