firmus energy customers to benefit from second tariff reduction this year

Customers of Northern Ireland’s largest supplier of natural gas, firmus energy, will benefit from reduced tariffs in the Ten Towns Network and Greater Belfast Network area for the second time this year, from today [01 April 2023].

In March, firmus energy announced a tariff reduction of 18.84% in the Ten Towns Network area and a reduction of 22.43% in the Greater Belfast Network area, both to take effect from 1st April.

Despite the UK Governments decision to reduce support for energy bills from 1st April, domestic customers with firmus energy will still benefit from a reduction in their tariffs.

Commenting on the price decreases, Niall Martindale, Chief Executive Officer of firmus energy said:

“firmus energy is delighted to be implementing its second price reduction this year”

“We have always committed to our customers that as soon as market conditions allowed us to lower our prices we would do so, and tomorrow we are introducing our second price cut of the year. We recognise the wider cost of living challenges within the communities we serve, and at firmus, we are working hard to make a positive change for each and every one of our customers."
