What can I do to protect myself against interruptions to my electricity supply?

Your electricity supply may be interrupted for a number of reasons. Some might be planned, but others may be unplanned. You can minimise the risk of damage to electrical appliances like computers, televisions, washing machines, dryers and heat pumps by installing:

  • Surge protectors
  • Power conditioners
  • UPS (Uninterrupted Power Supply)
  • RCDs (Residual Current Devices) and isolating transformers

To find out the best solution for your property ask advice from a local electrician or electrical outlet.


If there’s an interruption to your electricity supply, or your supply voltage drops switch off all electrical appliances at the wall outlet. This will help to prevent damage if there’s an electricity surge when the supply is restored. We recommend that you have insurance that covers you for loss or damage due to electricity supply interruptions or fluctuations.
