How to report a power cut in Cardiff
- Check your fuseboard. If neighbours still have power, a tripped switch in your own home is the most likely cause.
- Check the map above. If your area is listed, the network operator already knows and the estimated restore time is shown.
- Ring 105 if nothing is listed. It is free, open 24/7, and puts you through to the network operator for your postcode. Your energy supplier cannot fix power cuts.
- Fallen line? Keep well away, ring 105 straight away, and ring 999 if anyone is in danger.
Power cuts in Cardiff on our map come from National Grid.
Compensation, the Priority Services Register and what to do while you wait are covered in our UK power cut guide.
Keeping the power on in Cardiff during a power cut
Standard solar panels switch off when the grid goes down. A battery with a backup (EPS) function keeps lights, the fridge, Wi-Fi and heating controls running through a power cut, then tops itself up from the panels. See how it works in our battery storage guide, or compare solar panel installers in Cardiff.

Can I get compensation for a power cut in Cardiff?
Often, yes. Under Ofgem's Guaranteed Standards, homes can claim £100 if an unplanned power cut lasts more than 12 hours, plus £45 for each further 12 hours, up to a cap. Longer thresholds apply in severe weather and when more than 5,000 properties are affected. Claim from your network operator.
Do solar panels work during a power cut in Cardiff?
Not on their own. Grid-tied solar panels shut off automatically when the grid fails, to protect engineers working on the lines. To keep power during a cut you need a battery with a backup (EPS) function and an inverter that can isolate your home from the grid.
