Warranty Extension

So I have had my system for 2.5 years to date and I note that the warranty runs out in April 2025. I wonder if there are any plans to do extended warranties in case of issue beyond the expiry date. Otherwise would be concerned on how issues are resolved only 5 years into a high expense installation. I know this is a long way off at the mo but it will come around sooner that you think. Views?

There is an extended warranty but I think it had to be purchased within so many weeks of buying the system. I might be wrong.

I've just tried to extend mine, but it has to be purchased within 60 days of installation.
