Your Electricity Bill Explained
Irish electricity bills can seem complicated with various charges, levies, and taxes. But once you understand each component, you can make smarter decisions about your energy use and provider. Let's break it down.
The Unit Rate
This is the price you pay per kilowatt-hour (kWh) of electricity used. It's the biggest variable between providers and the main number to compare when switching. As of 2026, typical unit rates range from 32-45 cent per kWh depending on your provider and plan.
If you have a day/night meter, you'll see two unit rates: a higher daytime rate and a lower nighttime rate (typically 30-40% cheaper). Night-rate hours are usually 11pm to 8am.
If you have a smart meter, you may have access to time-of-use tariffs with three rate periods (day, peak, night), giving you even more opportunity to save by shifting usage.
The Standing Charge
This is a fixed daily charge for being connected to the electricity network, regardless of how much electricity you use. It typically ranges from €0.50 to €1.10 per day (€180-€400 per year).
The standing charge covers your share of maintaining the national electricity grid. It's set partly by ESB Networks and partly by your supplier.
The PSO Levy
The Public Service Obligation (PSO) levy is a government charge that supports renewable energy generation in Ireland. It appears as a separate line on your bill. The amount changes annually — in recent years, it has been set to €0 due to high wholesale electricity prices, but it can be reintroduced.
VAT
Electricity for residential customers is subject to VAT at 9% (reduced rate). This is applied to the total of your unit charges, standing charge, and PSO levy.
Carbon Tax
While carbon tax is more directly associated with heating fuels (oil, gas), it indirectly affects electricity prices as fossil fuels are still part of Ireland's electricity generation mix. As Ireland transitions to renewables, this impact should decrease.
Reading Your Meter
Your bill is based on either an actual meter reading or an estimated reading. Estimated readings can be inaccurate, leading to unexpected bills. If you have a traditional meter, submit regular readings to your provider. Smart meters send readings automatically.
Look for an 'E' on your bill next to the reading — this means it's estimated. If you're consistently getting estimated bills, contact your provider.
How Your Bill Period Works
Most providers bill every two months (bi-monthly). Your bill covers the usage between two meter reading dates. If you switch to monthly billing or direct debit, your payments are spread more evenly throughout the year.
Tips to Manage Your Bill
Set up a direct debit: Most providers offer a discount of €1-€2 per month for direct debit payment.
Go paperless: Some providers offer small discounts for e-billing.
Track your usage: Use Billmanage's bill management tool to track your bills over time and spot trends.
Budget billing: Some providers offer a levelised payment plan where you pay the same amount each month based on your estimated annual usage.
When Something Looks Wrong
If your bill seems unusually high, check for estimated readings, unusually cold weather periods, or new appliances. If you still can't explain it, contact your provider. The CRU has a dispute resolution process if you're not satisfied with your provider's response.
