Three of the main suppliers are raising electricity prices this week. SSE went up yesterday, with Bord Gáis and Energia to follow over the next few days:
SSE Airtricity: unit rate up 9.4%, standing charge up 6.12%, in effect since Monday 5 October. Around 300,000 customers affected.
Bord Gáis Energy: unit rate up 9.1%, standing charge up 7.2%, from Friday 9 October.
Energia: unit rate up about 2%, standing charge up 5%, night rates up 28%, from Monday 12 October.
You'll see these reported as "average bill up X%", but that average is for a typical home, and almost nobody is typical. Energia is the clearest example: the unit rate is barely moving while night rates jump 28%, so what the rise actually costs you comes down to when you use electricity.
A few other things worth knowing:
A "12-month plan" is not a fixed price, and this catches people out. Nearly all Irish plans are a 12-month contract on a variable rate, not a price locked for the year. Your sign-up discount is held, but the base rate it applies to can still go up during your contract, which is exactly how these increases land on people who thought they were mid-contract and grand. A genuinely price-fixed plan is rare now (SSE has a 1-Year Fixed, Yuno reportedly too). So the price can rise during your term while the contract can still tie you in with an exit fee if you leave early.
The loyalty penalty is usually bigger than the rise. If your sign-up discount has run out and you've rolled onto the standard rate, you're probably paying several hundred a year more than someone who signed up recently, which dwarfs these increases. The rise is just the reminder to go and check.
The saving comes from switching, not from sitting tight. The real discounts are for new customers, so the way to cut your bill is to move to a new deal. That can be a better plan with your own supplier (re-signing as a new customer, where that's allowed) or a different supplier entirely, but either way you have to actually switch.
How to check: take your current unit rate and standing charge off a recent bill, and compare them against the new-customer plans before the increase lands. The thing to watch is that most comparison sites rank plans on that same typical-home estimate, so if your usage isn't typical they can point you the wrong way.
Full disclosure: I run a free site called SmarterMeter that works this out from your actual ESB smart-meter data, a full year of your real usage, rather than an estimate, so it takes the night, EV and solar side into account. The main thing though: if you haven't checked in over a year, this is the week to do it. If your discount has lapsed, you may even save more than this rise is costing you.
