Energy outages
While Great Britain’s power system is very reliable, power cuts can still happen for various reasons.
If you experience a power cut, it’s important to know what to do and who to contact.
We ensure the continuous flow of high-voltage electricity to distribution network operators (DNOs). These operators then reduce the voltage and deliver electricity to homes and businesses across the country. If your home or business loses power, your local DNO is responsible for restoring it.
What to do if there’s a power cut in your area
- Switch off appliances like hair straighteners and irons, as they may turn back on automatically when power is restored.
- Call 105 to report the power cut. This free number connects you to your local distribution network operator, who is responsible for restoring power.
- Check on your neighbours, especially if they are elderly or unwell, to make sure they’re safe.

Who is my distribution network operator?
Who your distribution network operator is depends on where you live in the country.
Call 105 or use the online postcode checker to find out who your distribution network operator is.
Why do power cuts happen?
While national power cuts are rare, local outages can still happen due to:
- Natural causes: Lightning, flooding, or fallen trees can damage cables and equipment.
- Accidents:
- Contractors or homeowners may accidentally damage cables while digging.
- Cable insulation can fail unexpectedly.
- Fire or theft: These can damage network equipment or substations.
Who fixes it?
- Distribution Network Operators (DNOs) maintain the power lines that connect homes and businesses to the grid.
- If your power goes out, your DNO is responsible for restoring it.
