Electrical installation by a friend - Mandatory inspection due to insurance?

Hello everyone,

a good friend of mine is a trained electrician and works as an industrial electrician. Since we need a sub-distribution in the garage, he offered that I pull the cables and he could then connect everything. The only question I have is whether this could cause problems with the insurance because I wouldn’t have an invoice etc. for the work. Do I then have to have the installation checked by another electrician afterwards? I can’t quite imagine that an electrician would put up with that.

Best regards

The only question that arises for me is whether this can cause problems with the insurance

The only correct answer to that is: Yes, because you violate your duty of care and cannot prove that the system was installed properly. But: What you are doing is - although not correct - normal. As a private person, you are allowed to do things like connect a lamp, change light bulbs, and plug the toaster into the socket. Connecting a stove would already be "illegal". Or converting a single socket into a double socket by yourself ==> illegal.

I even heard once that connecting a lamp yourself is illegal if it doesn't have a plug. Which is a bit absurd. But I wonder, what happens in case of an emergency – for example, if the house caught fire – would I then have to prove everything to the insurance, who installed what and when?

But I wonder what happens in case of emergency – for example, if the house were to burn down – do I then have to prove everything to the insurance about who installed what and when?

Here too: it depends. It will partly depend on a) the insurance, b) the extent of the damage, and c) the cause of the fire. If, for example, it is determined that the fire was caused by the electrical installation, then definitely.

And whether the installation was then carried out privately by a trained electrician or by me probably doesn't matter, right? Is there a possibility to have a private installation inspected afterwards?

Is there a possibility to have a private installation inspected retrospectively?

Sure. Get an electrician like Ruben from classifieds or similar to inspect the system and issue a test report.
But be careful that the report doesn’t burn up in the event of a fire ;)
Providing proof is actually the biggest problem (if questions arise) when the place burns down, along with the documents. And it gets even more complicated with old buildings that have been sold multiple times. The documents will definitely disappear.

I wouldn’t worry about it at all…
Just do it and that’s it.
