Car insurance: why does my premium go up?

[Alberto]

Check24 informed me my current car insurer will up my premium, 173€ to 215€. I've had no accident and no claims for at least the last 5 or 6yr.
Why the premium increase?

[HEM]

Because the costs of accidents i.e. repairing cars has increased?

Ours went up a lot this year, too, with no claims.

We got a 12% discount for safe driving. Still went up.

Inflation.

While the answers to your question are all good up to now, and we're all set... However, you will not get a "correct" answer (considering "academic level") without posting a scan of the letter, to be honest.

So, scan that letter that you've got, redact the information that you do not want to disclose, and upload it here.

There are so many reasons why sh!t gets more expensive...

TBH, seversal years ago, I had a kind of similar situation. The car I bought (let's call it "Vauxhall Sh!tBox 1.2") at the age of 2 was now a car of the age of 12, and my insurance wanted a lot more money for the next year. I called my insurance broker, and he told me that my car is now the perfect "beginner's car for Papa to buy for the young unexperienced 18y old"...

Thanks for the answers.

25% inflation seems excessive. Even more as I was expecting a (small) reduction because of one more year of no claim and no accident.

And again: I got the info from check24, my "broker", not from the insurer. And it says nothing more than my original post.
I expect the letter I will eventually get from the insurer will not explain. Price increases, pardon "adjustements", are never really explained in my experience, same as gas electric etc.

[Fraufruit]

Price increases are inflation or greedy suppliers gouging people. What's to explain?

Loyalty tax. New customers get good deals funded by existing customers who don't bother searching for a better deal with a new company.

[Fraufruit]

Yes. That, too. Himself is constanly shopping around for better deals. Most people I know do the same. Often, you can bargain down existing providers with the cheaper offers. Not always, though.

I would say this makes sense. But as soon as I got the notification I ran a new comparison and it turned out the current offer from the current provider is the most economical.
So no, "loyalty tax" is not the answer.

Car insurance generally makes little sense.
I bought an older "sports car" last year and insured it as a 3rd car, starting at SF2. The insurance is less than 50% of our boring 2l diesel BMW family car with SF20.
That's with almost 2x the PS of the BMW.
Go figure!
