I finally solved the problem myself by completely draining,
flushing and refilling with a corrosion inhibitor. It's time consuming
and not the best time of year to do it, but well worth it if you
persevere.

I would have thought this is the best time to do it as the winter is
coming and people will be thinking about switching on their C.H. systems
soon.

I'm sure most people would have already turned their heating on by now!
Either that, or we're just having a localised cold period down in the SE.
If heating's being used, now isn't the time to be doing unnecessary
maintenance which could be deferred to a time when the heating is less
important.
