We have been out after another company as the customer got a nasty shock after an element was fitted, apparently the engineer was messing around behind the appliance for quite some time,
Earth not connected and a wood screw bodged into the earth connection as they had obviously broken the screw on the terminal block, we all like 1st call completions and going back for a £5.00 part is annoying but you cant leave a customer unsafe, there is no way this cooker was tested for electrical safety after the repair was done.
