Warranty for me is:

Solar panels: 10 years
Inverter: 12 years
Optimizers: 25 years
Effect warranty on panels: Minimum 80% after 25 years
Installation: 5 years

So I suggest you help your parents, read their contracts and maybe you will find out that there is still warranty. Anyway, even if they need to change the inverter, that's just a small cost compared to the whole installation. 27 panels, even if they are old, should produce at least some energy, much more than "next to nothing". Aren't they keep track of when things break? It is after all, a "machine" just like the washing machine, the car, the stove or whatever else. Must be kept under control to see it does what it meant to do. Everything can break, PV systems are not exception.

PV systems are not BS at all, and definitely worth the cost, but I know there are many not so serious installers, not only in UK but everywhere else.
Been looking into it as you suggested.
The company who fitted mum's went bust years ago. It's actually on of those installs where the company rents your roof from you.
Will have do do some deeper digging and find out who inherited the bust companies contract.

As for the father in law he bought his outright at the high rate Feed In Tarrif (FIT). It still makes enough to cover the initial cost and give about Ģ100 per yr in pocket. His quote is.....
'It's never been anywhere near what the salesman quoted but it will do'.
