How Often Should I Have My Consumer Unit / System Checked?

An electrical installation in a home should be checked out by an electrician every three – 5 years.

This is not only for safety purposes but to make sure that there are no power surges due to worn wires, faulty insulation, and other problems which could cause fires. In homes with small children & pets, it is important to check the wiring often as they are more likely to come into contact with the electrical system.
