Lost Power But Your Neighbours Haven't? Here's What's Actually Going On

If the whole street's lights are on but yours aren't, the problem is almost always inside your own home, not with the ESB supply. That's actually good news it usually means the fix is quicker, and often something you can safely check yourself before deciding whether to call anyone.

First, Rule Out the Obvious

On a prepay meter?

Check it before anything else — running out of credit is, by far, the most common reason for a sudden total blackout.

Check esbpowercheck.ie

Takes thirty seconds to rule out a fault on their end. You can also text POWER + your MPRN to 51444, or ring ESB Networks' 24-hour line on 1800 372 999.

If It's Genuinely Just Your House

Nine times out of ten, it's your consumer unit
(fuse board). Here's the usual order of suspects:

A tripped RCD or MCB

Your fuse board's way of saying "something's not right." A faulty appliance, a damp connection, an overloaded circuit. Check for a switch sitting in a different position to the rest.

A blown fuse

Same idea, just the old-school version if you've still got a rewireable board.

A faulty appliance

If the switch trips again the second you reset it, unplug everything on that circuit and bring things back one at a time.

What's safe to try yourself

If nothing looks damaged, damp, or burnt, go ahead and reset it once. If it trips again straight away stop. Don't keep flicking it back on. That's a real fault talking, not a fluke, and forcing it can make things worse.

🔴 When It's a Real Emergency

Stop troubleshooting and call an electrician straight away if you notice:

→ A burning smell near the consumer unit, a socket, or a light fitting

→ Scorching, melting, or discolouration around a socket or switch

→ Sparks when you plug something in or flip a switchA buzzing or crackling sound

→ A switch that's warm or hot to the touch

→ Any water near the electrics

If you spot any of that, don't keep testing it, cut the main switch if it's safe to, and get an electrician out.

When it's not urgent (but still worth sorting)

A circuit that trips now and again but resets fine isn't a 2am call-out. But it's not nothing either, get it looked at before it turns into a bigger problem.
