We have a double plug socket under the sink (that used to power the washing machine and dishwasher). However this plug has now burnt out. I understand having a plug under the sink is not a good idea, so we need the socket replaced and moved somewhere safer but still source the appliances we need. The added complication is that our house is old – many walls are the old horse hair plaster over slats, so we need a safe but practical solution that doesn’t cause the job to become larger than needed.
