Hi, so with the new changes to Part L etc, I guess a test of the system water is now included on everyone's annual boiler service. However, if you had to add inhibitor how much are you guys charging, as some are easy to add to, and some are a bit more complicated. Also OFTEC state that engineers don't have to clean system filters it's down to the homeowner, so are people charging separately for this service?
Many thanks 👍
