Installations from properties built in the 1960s and earlier are likely to have lighting without an earth
Answered by Rupert, Electrical Safety Expert
Installations from properties built in the 1960s and earlier are likely to have lighting without an earth. If you are renting out an older property, you should get a registered electrician to carry out an inspection of the installation and issue a report (EICR)*. They will be able to assess the risk and what needs to be done.
Our Best Practice Guide 1 (for professional electricians) has more information.

* In England and Scotland it is a legal requirement to have the electrical installation in privately rented properties checked every five years. We strongly recommend the same for properties in Wales and Northern Ireland.
