I rent a property in the UK. All of the sockets in my house were tripping, even when all sockets were switched off. An electrician came out, sent by the estate agent who manages the property. They determined it was an appliance of mine that tripped the power. He said something about why the socket was receiving power when the switch was off, but I'm not sure what it was he said as I am no electrician. Something to do with a neutral wire. I have received an invoice, from the estate agents, for me to pay the electrician as the fault was my appliance. I agree this would be my invoice to pay, however, I could have diagnosed the appliance as the fault myself had the landlords socket not been supplying power when switched off? Please could somebody advise me as to where I stand. Of course I am happy to pay if it is my responsibility. Thanks, Jean.
