Airtricity operates across Northern Ireland and the Republic of Ireland, and is owned by Scottish-based energy company SSE. It was the first company to set up in 2010, when switching supplier in Northern Ireland became possible.

There are two companies under the Airtricity umbrella: Airtricity Electricity and Airtricity Gas. 

It has around 350,000 customers, which is around a quarter of households in Northern Ireland. The company supplies gas and electricity to households in Greater Belfast, but only electricity to households in the Ten Towns area.

Airtricity claims to be Northern Ireland's leading company for renewable energy generation, and it sources 34.1% of its electricity fuel mix from renewable energy. SSE built Ireland's largest wind farm, which helps to power 75,000 homes. It also says it has invested more than £1.5m to local community projects based around its wind farms.

Our annual energy companies satisfaction survey is based on the opinions of almost 500 energy customers in Northern Ireland. As Airtricity supplies gas and electricity separately, we asked customers to rate them separately, too.

Which? verdict on SSE Airtricity Electricity

Although Airtricity Electricity is at the bottom of the table for overall customer score, it still gets a good rating for billing accuracy. 

It scored four out of five stars in this area – the same as all other NI providers – with 82% of customers saying accuracy was good or excellent. 

Customers were also generally satisfied with how Airtricity deals with complaints, with 29% of respondents calling it 'fair'. However, customers of the other NI suppliers we rated this year tend to say that their company is better at handling complaints, with most rating it either 'good' or 'excellent'.

The provider was let down by value for money, customer service, digital tools and bill clarity – scoring just three out of a possible five stars in all these areas. 

SSE Airtricity raised its electricity prices by 6.9% in October 2019, increasing the average customer’s bill by 75p a week.

One customer said: 'The costs seem to just increase and increase', while another stated: 'It promised cheaper prices, but mine have almost doubled, with three price rises within a year. I am disgusted'.

Pros: If you're interested in renewable energy, SSE Airtricity uses renewable sources in part, and is building a wind farm

Cons: Price increases have meant higher bills
