> But how much does the insurance cost?
Mine is about 350 a year, but they work out a rate per-appliance and then give a discount on the total, so you can pay more (or less) depending on how many appliances you cover.
> Are you positive this insurance, over the years, is cheaper than what you would have paid Miele directly?
Absolutely.
A Miele call-out will set you back 150 call-out + 100/hour, plus parts on top.
Or (if Miele agree) you can pay a "fixed-price" 300 which covers parts and labour (but again, this is subject to Miele's agreement and that agreement is given on a per call-out evaluation).
And as I said, one of my Miele appliances is 10+ years old, they've been back a good few times replacing increasingly major parts each time, so now the only thing 10+ years old about it is the external casing !
Even if I bought the "official" Miele parts myself, I value my time at greater than zero ! So its still cheaper than me buying the parts and spending a half a day pulling out appliances and fitting parts.
And given the price of new Miele appliances, its not exactly like after 5 years I could afford to replace everything with brand new appliances, since that would cost A LOT more than 350x5.
