I had my Worcester combi boiler serviced last week, and the engineer

I spoke to a local plumber who told me that it if was working, then

I might add that the boiler is working well.

So, as a consumer and householder with no technical knowledge what
should I do?

Thank you,

Check you've got a magnatec/zetec filter, those will filter out crud & prevent blockages. If not it's wise to fit one, much cheaper than fixing the inevitable years later.
