How to Cancel Your Energy Contract in Ireland (2026 Guide)

Switching energy supplier is one of the easiest ways to cut your bills in Ireland — but many people are put off by uncertainty around cancellation. What's the notice period? Are there exit fees? Do you have to contact your old supplier?

This guide explains exactly how cancelling an energy contract works in Ireland in 2026.

The Short Version

In most cases, you don't need to cancel your old contract yourself. When you sign up with a new supplier, they handle the switch — your old supplier is notified automatically through the network operator (ESB Networks or Gas Networks Ireland). Your old contract ends when the switch completes.

Do You Have to Give Notice?

For standard variable tariffs: No notice period required. You can switch at any time.

For fixed-term contracts: There may be a notice period or exit fee — but these are capped by regulation. See below.

The CRU (Commission for Regulation of Utilities) regulates switching rules in Ireland to protect consumers. Suppliers cannot lock you in with unreasonable exit terms.

Exit Fees: What You Need to Know

Exit fees in Ireland are capped by regulation:

• Electricity: Maximum exit fee of €100 (if you're breaking a fixed-term contract early)
• Gas: Maximum exit fee of €100 for gas contracts

In practice, many suppliers charge less than this or have no exit fee at all — especially if you're near the end of a fixed-term period.

How to check your exit fee:

• Look at your contract documents (emailed when you signed up, or in your online account)
• Call your supplier's customer service line
• Check your supplier's website under "terms and conditions" or "tariff information"

If you signed up on a variable (non-fixed) tariff, there is typically no exit fee.

Your 14-Day Cooling Off Right

If you recently signed up with a new supplier and changed your mind, you have a 14-day right to cancel under consumer protection law — with no penalty.

To cancel within 14 days:

1. Contact the new supplier directly (phone or email)
2. State you wish to cancel under your cooling-off rights
3. You'll stay with your current supplier as if you never signed up

How the Switch/Cancellation Process Works

When you switch energy supplier in Ireland, the process is:

1. You sign up with the new supplier — online, takes 10 minutes
2. New supplier notifies ESB Networks (electricity) or Gas Networks Ireland (gas)
3. Your old supplier is automatically notified — you don't need to call them
4. Switch completes in 5–7 working days — a meter read is taken at the switch date
5. Final bill from old supplier — you receive a final bill based on your actual usage up to the switch date. If you've overpaid on direct debit, the credit is refunded.

You do not need to cancel your direct debit with your old supplier before switching — they will close your account and cancel it when the switch completes. However, it's worth double-checking a few weeks after the switch that no further payments have been taken.

What If You're Moving Home?

If you're moving house, cancelling your energy contract is handled differently:

1. Contact your supplier and give them your move-out date
2. Request a final meter read on your last day at the property
3. Pay any outstanding balance
4. The new occupier or landlord takes over the account (or the supply may go onto a default tariff temporarily)

You don't need to wait for a switch — you can cancel directly when moving.

There is typically no exit fee for cancellation due to moving home, even on fixed contracts.

What If You're Renting?

If you're a tenant responsible for your own energy bills, you have the same rights as any consumer. You can switch at any time — you don't need landlord permission to switch supplier (as long as you're the account holder).

Cancelling During a Dispute or Complaint

If you're in a billing dispute with your supplier, you can still switch — but unresolved debt on your account may complicate the process.

Under CRU rules, a supplier can block a switch if you owe more than €225 on an electricity or gas account. If your dispute involves a charge you're contesting, consider:

1. Escalating your complaint to your supplier's complaints process
2. If unresolved after 10 working days, referring to the CRU's complaint resolution process
3. Switching once the dispute is resolved

Common Questions

Will my electricity be cut off when I switch? No. Supply is never interrupted during a switch. The physical infrastructure (wires, pipes) is managed by the network operator and doesn't change.

Do I need to read my meter when I switch? A meter read is taken automatically by ESB Networks or Gas Networks Ireland around the switch date. You can also submit a meter read yourself for accuracy.

What if I have a smart meter? Smart meters record half-hourly data that's shared between your old and new supplier at the switch date, making the final billing more accurate.

Can my old supplier stop me switching? Generally no. A supplier can only delay a switch if you owe more than €225 or if there's a technical issue with your meter. They cannot block a switch as a penalty for leaving.

What happens to my credit balance? If you've overpaid on direct debit, your old supplier must refund the credit balance within a reasonable time (typically within 6–8 weeks of your final bill being issued).

Step-by-Step: Switching (Not Just Cancelling)

If your goal is to get a cheaper deal — not just cancel — here's the full process:

1. Go to GoSwitch and enter your annual usage
2. Find the cheapest tariff for your home
3. Click through and sign up with the new supplier (10 minutes)
4. The switch happens automatically — no need to contact your old supplier
5. Receive your final bill from the old supplier 4–6 weeks after the switch date

That's it. The average saving by switching in 2026 is over €300/year.
