Yuno Energy: Ireland's newest electricity and gas provider

As of 29 June 2023, Electric Ireland was named the cheapest supplier of energy to the Irish market by the regulator, the CRU. However, Yuno Energy is Ireland's newest electricity and gas provider and offers competitive pricing on its dual fuel, electricity, and gas plans.

Yuno Energy's pricing is dependent on your location and meter type. You must have an Electricity Supply Board Networks (ESBN) electricity smart meter installed and a Gas Networks Ireland (GNI) gas credit meter. The Yuno Dual Fuel Plan is for customers with usage of less than 73,000 kWh per year. If your usage is greater than this, you will be moved to a large user gas plan.

Yuno Energy offers a discounted rate of €1300 in year one for medium-sized homes that probably use gas, oil, or solid fuel to provide heating and hot water. This is an annual electricity usage of about 4200 kWh per year, which is the national average usage figure.

Yuno Energy has a 4-star rating on Trustpilot, with 1,127 reviews. Positive reviews mention the smooth cancellation process, excellent customer service, and quick resolution of issues. However, some negative reviews highlight inaccurate billing practices and a lack of accountability from the support team.

To sign up for Yuno Energy, you will need your email address, mobile number, MPRN or Eircode, GPRN, gas meter reading, and bank card.

Flogas also ranks highest in terms of the cheapest standard natural gas supplier for existing customers, billing households €1,838 a year. SSE Airtricity is a close second, charging €1,838 a year.

Flogas Community Plan is also a good option, with rates of 30 cent on a 24-hour meter, while most other plans are 40 cent or more. These rates are fixed for one year, so there are no surprises.

SSE Airtricity: cheapest standard natural gas supplier for existing customers

Energy prices in Ireland are high, and it is recommended that households compare electricity prices and consider switching suppliers to obtain the best deal. The cheapest overall supplier in Ireland is Electric Ireland, according to the energy regulator, the CRU. However, the CRU also states that SSE gas customers get the best standard-rate deals. SSE Airtricity is the cheapest standard natural gas supplier for existing customers, charging them €1,838 a year.

SSE Airtricity offers a range of payment options for its customers. You can pay by Quarterly Credit, which means receiving a bill every three months for the amount of gas used in the previous quarter. This is payable after 14 calendar days. There are no discounts available with this payment method, and it is subject to a credit check. You can also pay by Direct Debit, which allows you to spread the cost with 12 upfront monthly payments to avoid winter price spikes. SSE Airtricity will notify you in advance of any changes to the amount, date, or frequency of your Direct Debit. Finally, you can pay as you go, paying for your gas as and when you need it, with no unexpected bills.

SSE Airtricity also offers a 14-day cooling-off period for new customers, during which you can cancel your switch request by contacting the company directly. After your request to switch is processed, your current supplier will notify SSE Airtricity of any overdue payments. SSE Airtricity will then send you a closing bill for gas usage based on your final meter reading, which may include usage not covered by your monthly instalments.

SSE Airtricity also provides exclusive access to tickets, the SSE Reward Lounge, and discounts on various brands. The company also offers outstanding customer service, including its Energy Care Scheme.

Electric Ireland: cheapest supplier of energy to the Irish market

Electric Ireland has been declared the cheapest supplier of energy to the Irish market by the CRU (the Commission for Regulation of Utilities). The CRU calculates that Flogas's discount rate for new customers is €1,801 a year, while Electric Ireland's is €1,933. Flogas's smart "time-of-use" plan is €1,670 annually, while Electric Ireland's is €1,740.

While SSE Airtricity offers the cheapest standard natural gas rates for existing customers, Electric Ireland's rates are still competitive. SSE Airtricity charges €1,838 a year, while Electric Ireland's rates are only slightly higher.

It is worth noting that the Irish energy market is dynamic, and prices are constantly changing. While Electric Ireland currently offers the cheapest rates, other suppliers like Flogas and Yuno Energy are also known for their competitive discounts and introductory rates.

To ensure they are getting the best deal, Irish consumers are advised to compare electricity prices regularly and consider switching suppliers every 12 months. By doing so, they can take advantage of the competitive introductory rates offered by many energy providers and avoid paying more than necessary.

In addition to supplier rates, there are other ways for Irish consumers to save on their energy bills. One option is to install solar panels, which can generate about 6,000 kWh per annum in Ireland and offer electricity at a lower cost than even the lowest-cost suppliers. Another way to save is to reduce electricity wastage in the home, which can be identified by viewing smart meter data online.

Solar energy: can work out cheaper than the lowest-cost suppliers

As of June 2023, Electric Ireland is the cheapest supplier of energy to the Irish market, according to the regulator. The CRU estimates that SSE gas customers get the best standard-rate deals, while Flogas offers the biggest discounts. However, switching suppliers or renegotiating with your current supplier can still deliver savings.

While Ireland's electricity prices have skyrocketed in recent years, solar energy offers a promising alternative. Solar panels can reduce your electricity bills by decreasing the amount of electricity you buy during the day, especially in the summer. With solar panels, you can also sell your surplus electricity to the grid and completely eliminate your electricity bills.

Solar PV panels are a popular choice in Ireland due to their demand, affordability, and reliability. There are three main types of solar PV panels: thin-film PV panels, mono-crystalline, and polycrystalline PV panels. Polycrystalline panels are less efficient and usually larger but are a cheaper option. Solar panels typically last between 20-30 years, after which their efficiency substantially reduces.

To maximise your savings with solar panels, choosing the right electricity plan is crucial. A day/night tariff or EV tariff is usually recommended for homes with solar panels. Additionally, consider export payments, as you can earn money by exporting your surplus daytime solar energy.

By combining solar panels with the appropriate electricity plan, you can potentially achieve cheaper energy costs than even the lowest-cost suppliers in Ireland.
