Hi I am In the process of selling my house and the buyer has had an electrical survey carried out and the electrician has stated that neither the lights or plugs are earthed. I have checked 3 plug sockets and although are unsheathed there is an earth wire… but I not sure about the lights… he also says it is unsafe as the house is only on one circuit (very small 2 bed semi detached) and it needs a rewire at the cost of £4,000! The purchaser has now asked me to reduce the agreed price based on this… can anyone help confirm if this is right ???
