Government officials are currently debating electrical safety in rented homes with a view to making electrical checks a compulsory requirement for landlords.
The state of play at the moment
Currently, it is only a recommendation to have an electrical check carried out in a rented property. Additionally, it is also highly recommended to Portable Appliance Test (PAT) all electrical appliances supplied as part of the rental agreement i.e. washing machines, kettles, electric heaters etc.
