Switched to Energia Ireland but had a change of heart?

After switching to Energia or renewing your contract, you have a 14-day cooling-off period. During these two weeks, you can cancel your contract at any point free of charge.

If you cancel after 14 days, you’ll be subject to a €50 termination fee per fuel contracted (so €100 if you contracted a dual fuel option). We don’t recommend doing this unless you find a much better offer that more than makes up the difference.

Energia login: Access your online account


After signing up to Energia Ireland, you'll be able to access your online account. Energia has separate login accounts for business and residential customers, and online facilities include being able to view bills, payments, submit meter readings and estimate your next bill.

The ability to estimate your next bill is a really useful option, allowing you to keep track of your spending and make sure you stay within your budget.

In addition, their paperless billing option (bimonthly) is different to other companies in that once you’ve signed up with them online unless you specifically request a paper bill, they’ll never send you a paper version. This is very much in keeping with their green ethos.

Energia Ireland also says that by registering online, you may be entitled to an online billing discount, and after contacting their sales team we can confirm that you’ll be given a 4% discount off the standard unit price.

Customer reviews: Is Energia any good?

On customer review site Trustpilot, Energia has an average rating of 4.4 out of five stars. Of the almost 4,000 customers who left Energia reviews, 71% rated the supplier as either great or excellent. Only 15% of customers scored Energia as either poor or bad.

Many customers gave Energia a five-star rating, noting the reason being for its helpful and attentive staff. Customers also praised Energia for its discounts and competitive offers.

“The cheapest rates in Ireland and great Customer Service. I'd highly recommend.”

Asta Trustpilot review

The customers who left negative Energia reviews often said that they disliked receiving two separate bills when they were on a dual fuel contract and that Energia doesn’t remind people to submit meter readings, whereas several other companies in Ireland do.

No matter the context of the Energia review, we did notice that the supplier's engagement with customers is quite high. Customer service representatives have responded to nearly all Energia reviews. It also appears the supplier makes an effort to change services where possible in order to please customers.

Pay As You Go services

PAYG Energia does not provide PAYG services to the general public. The supplier only provides prepayment plans to customers who need help managing their debts, or to customers experiencing financial hardship (proof required). If you fit one of these categories and you’d like to learn more, call Energia to find out if you can get a PAYG offer.

PAYG is the most expensive way to pay for energy.Call us and we'll help move you to a cheaper tariff, fast. Call 15 133 668 or get a free callback now.

Energia FastPay

Energia FastPay allows customers to make partial or total payments towards their next energy bill. It allows for you to build up credit so you're not hit with a full bill at one time.

For customers who pay via direct debit, it's important to note that you can only make advanced payments with Energia FastPay. You will not be able to use the service to pay a bill that has already been issued.

Energia Extra

While a good effort and something for nothing is never a bad thing, Energia Extra’s rewards program is missing our favourite option, which is the ability to get points on your supermarket card and apply them to your energy bills, as with Bord Gáis Energy Rewards and Electric Ireland Rewards.

It would also be great if they didn’t have a separate login for Energia Extra and instead had an all-in-one login, like Bord Gais Energy with MyBGE.

They offer discounts at retailers (e.g. stationery, web design, golf), spa and hotel deals, and competitions. Login here and have a look at what’s on offer, and remember you’ll need to register in order to claim any rewards.

Remember that Energia extra is not an automatic inclusion into your online offering, so find your account number and get on it in order to avoid missing out on any deals.

Cosy Homes Scheme

Under the Cosy Homes Scheme, and in order to reduce energy waste, Energia Ireland provides:

  • Boiler servicing.
  • Boiler replacement.
  • Help with applying for grants.
  • Installing and improving insulation and lining.
  • Solar panel installation.
  • Smart thermostat (Netatmo) installation.

Energia Boiler Service


For peace of mind and sheer practicality, arranging your Energia boiler service could also be a handy option. Your boiler must be serviced at least once a year to keep it in tip-top condition.

Not servicing your boiler might lead to dangerous faults developing, and can also affect its efficiency, as many of the parts are cleaned and tested during a service. A well-maintained boiler is a more efficient boiler, and a more efficient boiler means more money in your pocket and less on your bill.

The Energia boiler service is priced at €95) and is, of course, carried out by an RGII registered gas installer. You can book your 28-point boiler service using the online enquiry form to arrange a callback, or by calling 1850 300 700.

Energia Boiler Replacement

For boiler replacement, Energia will replace your older boiler with a condensing boiler (currently recognised as the most efficient boilers on the market). Energia will then add zoned heating controls during the installation. While the normal price for installing the boiler and two heating controls would be an eyewatering €2,600, Energia customers can get it done for €2,340.


Grants that Energia Ireland can help you with include SEAI’s Better Energy Home Scheme, and the Irish Government’s Home Renovation Incentive. Basically they’ll handle all the paperwork for you, and let's be honest - nobody likes doing paperwork!

For insulation and lining, they offer four options:

  1. External wall insulation.
  2. Cavity wall insulation.
  3. Dry lining/internal wall insulation.
  4. Roof or attic insulation.

We do recommend looking into insulation, as it’s one of the most cost-effective ways to reduce energy waste and your bills.

Solar panels

For solar panels, they offer to install flat panels on your roof for your hot water needs. The normal package costs €6149 but Energia customers can get it for €4650 (including discounts and grants).

Hot water is a massive cost to any household, and we do love solar energy here at Selectra Ireland, but it really depends on your disposable cash and the size of your household whether this would be a worthwhile investment or not - you'll also need to consider how long the warranty lasts and the cost of replacing any fuel cells or batteries. Have a look at our guide on solar panels, do the math, and decide for yourself.

Smart Thermostat (Netatmo)

Energia Ireland provides the Netatmo smart home thermostat, as well as installation, for €249, but you can also sign up for the Netatmo package and get it for free. It’s worth noting that the Netatmo was voted the best buy in the smart thermostat category by Which?, the prestigious UK based consumer association.

To take up any of these Cosy Homes Scheme offers, they can’t be contracted online so either fill in this form to receive a callback or directly call the supplier for more information.


Energy Bioenergy is the largest anaerobic digestion plant in Ireland and is the fruit of a collaboration between Energia and Panda. The Bioenergy plant began operations in Huntstown Dublin in 2019 after an agreement worth €50m was signed between the two companies.

What is an anaerobic digestion plant?Anaerobic digestion is a common natural process whereby biological materials such as plant material, is digested by micro-organisms. The materials are contained without air, hence “anaerobic”. This digestive process produces biogas which is then harvested and can be used as a gas or to produce electricity.

Panda will supply Energia with 70,000 tonnes of organic waste which is to be converted into electricity. Remnants of the anaerobic digestion process will be used as organic fertilizer.
