Switching Electricity Supplier in Ireland: How It Works, Why the Standard Rate Costs More and How to Read Your Bill
Many Irish households have never changed electricity supplier, and many more moved onto a standard rate without noticing when a first-year discount ended. With winter bills arriving, this guide explains how switching works: the wires, the meter and the supply stay the same, only the company that bills you changes, with no interruption. It sets out why a standard unit rate usually costs more than the rates offered to new customers, how to read the unit rate, standing charge and levies on a bill, what smart meters and day/night or time-of-use plans change, how contract length and exit fees work, and how to check that a comparison site is accredited by the regulator. Savings depend on your usage and plan, discounts usually end after the first year, and gas, electricity and dual fuel are separate decisions. The guide recommends no supplier and names no brand.
Switching electricity supplier in Ireland: same wires and meter, no interruption to supply, and the MPRN the new supplier needs
When you switch electricity supplier in Ireland, the same wires and meter stay in place. The network operator still delivers power to your home, so there is no interruption to supply. Your new supplier simply takes over the billing and customer account. To start the process, the new supplier needs your MPRN, a unique number that identifies your connection point. You can find it on a recent bill or by contacting the network operator. Local services and comparison tools can help, but the MPRN is the key detail that links your home to the switch.
Standard unit rates and new-customer discounts: why a bill rises when a first-year discount ends and the plan rolls over
Many electricity plans attract new customers with a discount on standard unit rates for the first year. When that discount ends, the plan may roll over to a standard rate, and the bill can rise without any change in usage. The standing charge and other fixed elements usually stay similar, but the unit rate difference can be noticeable. This is why reading the terms matters. A plan that looks cheap in month one may cost more in month thirteen. Checking the end date and the standard rate before signing helps avoid surprises.
Reading an electricity bill: unit rate, standing charge, the public service obligation levy, VAT and estimated readings
An electricity bill in Ireland usually shows several separate charges. The unit rate is the price per kWh used. The standing charge is a fixed daily or annual amount for connection and service. The public service obligation levy supports renewable and sustainable energy programmes. VAT is added to the total. If the meter reading is estimated, the bill may be based on past usage rather than an exact reading, and a later actual reading can adjust the balance. Knowing each line helps you compare plans on a like-for-like basis.
Smart meters and plan types: day/night, time-of-use and standard plans, and how household usage decides which one suits
Smart meters record electricity use in more detail and can support day/night, time-of-use and standard plans. A standard plan charges one unit rate at all times. Day/night plans offer a lower night rate and a higher day rate. Time-of-use plans split the day into peak, off-peak and sometimes peak periods, with different rates for each. The right choice depends on household usage. A home that runs heavy appliances at night may benefit from a night or time-of-use plan, while a household with steady daytime use may prefer a simpler standard plan.
Contract length and exit fees, checking a comparison site’s accreditation, and gas, electricity or dual fuel as separate choices
Before switching, check the contract length and any exit fees. Some plans have a fixed term with a fee for leaving early, while others are open-ended. Comparison sites can help, but it is wise to check whether a site is accredited by the Commission for Regulation of Utilities. Also remember that gas, electricity and dual fuel are separate choices. A dual fuel discount may bundle both, but it is not always the cheapest option. You can switch one fuel, both fuels, or keep them with different suppliers.
What do electricity plans and prices look like?
Real-world prices vary by region, meter type, usage and time of year. The table below gives a general guide to typical plan structures and estimated costs from suppliers active in Ireland. These figures are not quotes and should be checked directly with each provider. A standard 24-hour plan usually has a single unit rate plus a standing charge. Smart time-of-use plans can have lower off-peak rates but higher peak rates. Prepay plans often have different top-up and rate structures.

| Standard 24-hour urban electricity plan | Electric Ireland | Around 0.30 to 0.35 euro per kWh plus standing charge |
| Standard 24-hour urban electricity plan | Bord Gáis Energy | Around 0.30 to 0.36 euro per kWh plus standing charge |

Switching electricity supplier in Ireland is mostly an administrative change, not a physical one. The same wires and meter continue to deliver power, and the main differences appear in unit rates, standing charges, discounts, contract terms and plan types. Reading the bill carefully and checking the MPRN, contract end date and any exit fees can make the process clearer. With smart meters and time-of-use plans, household usage patterns matter more than ever. A calm, informed comparison is the most reliable way to understand what a plan may cost over time.
