Hi,
from my point of view, construction all-risk insurance definitely makes sense, especially with individual contracts and own work. It’s not just about vandalism or theft, but above all the many “nobody-did-it” damages that occur more often in practice than you think. If something breaks and nobody claims responsibility, without construction all-risk insurance you’re simply stuck with the costs.
Especially when different trades are running around on the construction site, it’s easy for something to get damaged without you noticing immediately. And even if you do notice it, it doesn’t help much if nobody takes responsibility. It’s just more relaxed when you can say: okay, it’s annoying, but the insurance will take care of it.
When it comes to natural hazards, it’s more difficult. Sure, if you really have zero risk, meaning no stream, no hillside location, no hollow-like position, and no heavy rain problems in the area, you can leave it out. But the last few years have shown that heavy rain causes problems even in areas where there was never any before. So if it doesn’t hurt your budget, I’d rather keep it in. The few hundred euros per year aren’t exactly cheap, but if you ever actually have damage, you’ll be glad you included it.
All in all, your package doesn’t sound too bad. If you still want to compare providers, take a look at InterRisk, Rhion, or VHV. They sometimes offer good coverage at fair prices, especially for residential buildings and construction coverage.
Best regards
