£500 was a fixed price, but i am sure it should last longer than thatThey normally do fixed price repairs, not sure if it includes HX any more though

it has not been serviced every year ....i know that for sure, would that invalidate the guarantee? not sure what you mean by neglected?

he didnt install itThe manufacturers expect the boiler to be serviced annually.
It sounds like an illegal install if he is not gas registered in his own name!
