Which? verdict on Electric Ireland
Electric Ireland has secured first place in this year's survey.
Its customers consider it to be reasonably good across most areas, including value for money and providing clear bills. Electric Ireland was the only NI energy provider to get a four-star rating in more than one area.
Electric Ireland's customers told us they were particularly happy with the clarity of their bills, with 84% rating them good or excellent. There was only one supplier (Budget Energy) which scored higher in this area.
Electric Ireland's customers also rated it highly for value for money. One customer commented: 'It was the cheapest when I signed up, and again when I checked a few months ago.'
It offers you an incentive of €150 to switch to it, and a customer loyalty scheme called Electric Ireland Rewards. The scheme gives customers discounts on things such as hotel stays, plus the chance to win prizes.
Customers had mixed comments about the firm's customer service: one told us it's 'always efficient and friendly', but another said the team had an 'unhelpful attitude'.
The 'easy' online account service - digital tools were rated three stars out of five - was also mentioned a few times. One customer said it was 'easy to access my online account', while another simply said 'easy to use'.
Pros: You get €150 incentive to switch to Electric Ireland
Cons: If you don't pay by direct debit, there's a security deposit of £200 - this is refunded after 12 months, provided all accounts have been paid on time and in full during the year
