This depends on the type of appliance. But, as a general rule. Electrical appliances should be inspected at least every 2-3 years.
Some appliances, such as refrigerators and air conditioners, have specific inspection requirements that should be followed to make sure they are safe to use. For example, refrigerators should have the coils cleaned every 6 months to prevent a fire hazard.
If you are unsure about when your electrical appliances need to be inspected, it is best to consult with our electricians. They will be able to advise you on the specific requirements for each appliance and how often they should be inspected.
