Can I dispute an electricity or gas bill in Ireland?
Yes — but you must complete the supplier's complaints process before the regulator steps in. Complain to your supplier first (for billing) or the network operator (for a faulty meter); escalate to the CRU only if it's unresolved. Suppliers must resolve a complaint within 2 months (8 weeks) and confirm closure in writing; if they miss that or you're still unhappy, the CRU investigates. Bills flag the read basis: A = actual, C = customer, E = estimated, and ESBN reads the meter about 4 times a year. Before disconnecting for non-payment, a supplier must make at least 4 contact attempts and offer a payment plan — and if you engage, you can't be disconnected. VAT on energy is currently 9%. There's no separate energy ombudsman. In short: yes, via the supplier then the CRU.
📋 The rules
- Complain to the supplier first, then the CRU
- Supplier must resolve within 2 months
- Bills show the read basis: A / C / E
- 4 contact attempts + a payment plan before disconnection
- Engage and you can't be disconnected
🔓 Exceptions
- Vulnerable-register customers can't be disconnected at any time
- Smart meters send automatic reads, so estimates shouldn't arise
- A CRU decision binds the supplier — you can still use Small Claims
⚠️ Penalties & fines
The CRU aims to acknowledge within 5 working days, gets the supplier's report within 10–15 working days, gives you 10 working days to comment, and issues a final decision within 90 days, with upheld remedies implemented within 3 weeks. There's a winter disconnection moratorium: for registered vulnerable customers (1 Nov–31 Mar) and for all domestic customers over the Christmas period. A supplier must make at least 4 contact attempts and offer a payment plan before any disconnection, and an engaged customer isn't disconnected. Beware a myth: "I can go straight to an energy ombudsman" is false — there's no separate energy ombudsman; the CRU is the regulator and only investigates after you complete the supplier's process. To dispute: complain in writing to your supplier, then escalate to the CRU if needed.

❓ Frequently asked
How do I dispute my energy bill?
First, complain directly to your energy supplier, ideally in writing, explaining the problem — for example a bill that seems too high or based on an estimate. The supplier must investigate and resolve it within two months. If they don't, or you're not satisfied with the outcome, you can then escalate the complaint to the regulator, the CRU.
What if my bill is just an estimate?
Bills show how the meter reading was obtained: A for an actual reading by the network, C for a customer-submitted reading, and E for an estimate. If your bill is estimated and looks wrong, you can submit your own meter reading to your supplier to have it corrected. Smart meters send automatic readings, avoiding estimates.
Can I be disconnected if I'm disputing a bill?
Before disconnecting for non-payment, a supplier must make at least four attempts to contact you and offer a payment plan. If you engage with them — for example by agreeing a plan — you can't be disconnected. Vulnerable customers on the priority register are protected from disconnection at any time of the year.
Is there an energy ombudsman?
No. There's no separate energy ombudsman in Ireland. The Commission for Regulation of Utilities, or CRU, is the energy regulator and handles complaints, but only after you've gone through your supplier's own complaints process and either it's unresolved after two months or you're dissatisfied with the result.
How long does a CRU complaint take?
The CRU aims to acknowledge your complaint within about five working days, obtain the supplier's report within 10 to 15 working days, give you ten working days to respond, and issue a final decision within 90 days. If it upholds your complaint, the agreed remedy should be put in place within about three weeks.
