They are don't like that unqualified people play with gas or electricity, so they certainly don't try to make it easy for people to be able to repair themselves.
What do you mean? The repair in Poland would also be done by a qualified electrician or a gas technician . It's not the qualification requirement that is pushing the cost up, it's simply that the wages are so much higher. A very very basic £10/hour in the UK is absolutely astronomical for Poland(50PLN/hour is maybe what a senior programmer would make, not an electrician).
