ᐅ Renovated Extension – Insulation Installed Unprofessionally

Hello dear experts,
I recently became the owner of a house with an extension. The extension was renovated in 2019 by the previous owner. At that time, he installed the insulation himself because he considered the cost of 2,500€ for insulation and plastering too expensive... 🙁
I have now asked a plasterer to apply the render on the panels. However, he said that the panels were installed so unevenly and misaligned that he would remove them again. Furthermore, he could not guarantee that the panels and plaster would properly adhere to the insulation if the panels were simply plastered over.
As a result, the price for removing, re-insulating, and plastering (for almost 70sqm (750 sqft)) has increased to nearly 6,000€. Do you think this price is reasonable, or would you remove the insulation entirely?
See pictures.
Thanks for your advice!

This isn’t going anywhere. First, get the often recommended second opinion. And if you don’t have the money right now, then do it in 1, 2, or 3 years. I know the situation, we’re renovating as well. Three years ago, we started with the urgent tasks until the money ran out, and since then we’ve been doing the rest step by step, as the budget allows. Depending on the tradespeople’s advice, you can remove this insulation or leave it in place for now, but the plastering isn’t going anywhere. Or are there any urgent follow-up trades depending on it? At worst, you’ll just have slightly higher heating costs for a while due to missing or poor insulation.
