we have a Worcester Bosch GREENSTAR CDi CLASSIC combi boiler, fitted 8

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

My Worcester Bosch system boiler was installed nearly 16 years
ago.

Just out of its 2 year warranty the PCB failed, and I had it
serviced as part of the repair. Usefully, it was discovered that
my incoming main gas regulator was out of spec, so a quick call
got that swapped pretty swiftly.

No further work or, to temp fate, problems so far.

I was always a little sceptical that the cost of a mandatory
annual service and/or early failure of a more complicated piece
of kit, could easily exceed the value of energy saving.
