You should charge extra for testing previous installations.


I do charge for the test.

It should not be compulsory. Your contract is to fit the shower. You
should only be responsible for the work that you put into the house.

But an electric shower in a place that has a defective electrical
installation
is obviously a much higher risk of killing someone in that shower, stupid.
