Checking for damage
It’s been the case for a while now that in order to rent out a privately rented property the landlord must have a valid electrical installation condition report (EICR) that confirms that the installation within that property is satisfactory for continued use.
These inspections must be done at most every five years.
I was musing today that, for example, if a property has had a challenging tenant, it’s good practice to have the electrical system inspected and tested when tenants change over.
