I do go out to service Isars and Icos boilers, unfortunately I fitted about 100 before all the carp design and parts problems became apparent.
I also get my name given out by Ideal customer services if a customer asks them who is in my area to service their boilers.
I have asked them to stop that though.
Just because the customer has a problem boiler that I hate now, does not mean I leave them without any servicing. My customers are always right and I try to always help them, something that Ideal as a company could learn from
Any fault that will end up with me charging the customer more than £200 (which to be honest is nearly all of them), I recommend them to call out Ideal under a fixed price call and I do not charge them anything.
There is also a major problem with Ideal supplying parts, well at least the correct ones that are ordered
