A power cut is disruptive and, in cold weather, worrying — but help is only a phone call away, and you don’t have to work out who your network operator is.
This is what to do.

Call 105 — the free power cut line

If your power goes off, call 105. It’s a free national number that connects you to your local electricity network operator — the company that runs the cables and substations, which is different from the supplier you pay. They can tell you what’s happening and when power should be back. 105 also lets you report damage to power lines or substations that could put someone in danger (if there’s an immediate risk to life, call 999).

Check it’s not just your home

Before calling, check whether your neighbours are affected too. If it’s only your home, the problem may be your own fuse box or a tripped switch. If a wider area is out, it’s a network fault — that’s what 105 is for. (For a gas emergency or a suspected leak, call the National Gas Emergency line on 0800 111 999 instead.)

Extra help if you need it

If you’re of pension age, disabled, have a young family or rely on medical equipment, sign up to your network operator’s free Priority Services Register — it means you get extra support during a power cut, such as priority updates and, in some cases, alternative heating or a welfare visit.

Compensation for long cuts

Network operators must meet guaranteed standards for restoring power, and if a cut lasts an unusually long time you may be entitled to a compensation payment, often paid automatically. It’s worth checking with your operator if you’ve had a lengthy outage.

What to do next

Save 105 in your phone now, and consider joining the Priority Services Register. For help with energy bills and your rights as a customer, see our suppliers, bills and meters and energy bill support pages.
