How much does it cost to thermally insulate an old house in 2026?

I've got a post-war farmhouse in Bergamo and heating costs me a fortune. I was thinking about getting external thermal insulation, but I have no idea how much it might cost or if there are any incentives still available this year. I need realistic numbers to figure out if it's worth it before I call a surveyor.

Thermal insulation on an old farmhouse in the Bergamo region will probably cost you €80 - 150 per square meter, so if the external surface is around 200 - 300 sqm you're looking at figures between €16,000 and €45,000, depending a lot on how irregular the masonry is and whether you need to do preparatory work. For incentives in 2026 you should check the Superbonus or standard tax deductions (which generally cover 65% of the expense), but the programs change year to year so call a surveyor first because they'll give you a realistic quote and will be better informed than anyone on the internet about what actually makes sense for your specific situation.
