Do you actually know what you paid for on your last boiler service?
Photo one is a heat exchanger on a service this week, before and after, about ten minutes apart. Photo two is a magnetic filter I pulled out of another system this week.
A lot of job reports never show you any of this. A line or two, you take the engineer's word for it, and the boiler looks exactly the same once the case goes back on.
So on every service I photograph what I find, and the photos go on your service record with a plain English note on what they mean. If something needs sorting, you can see why. If it is all fine, you can see that too.
I have written up what actually happens on one of my services, step by step, with more photos, here:

If your boiler is due a service before the cold really sets in, you can book online here:
