Is it a good idea/necessity to have it serviced every year?

What does the panel think please?

When my Potterton Suprima was installed around 20 years ago I asked
the installer about servicing and he said that he wouldn't bother.
The closest it has come to a service was a few years later when the
PCB needed replacing (which I learned about here) and I cleaned out
the combustion chamber at the same time as replacing it.
