A new energy price war could be on the way.
SSE Airtricity is set to cut the cost of its electricity supply by almost 13% , and its gas by 11.5% They kick in from February 1st.
When combined with a previous cut which took effect in November, SSE's tariff's will have fallen by 20 per cent since the summer.
Its likely to put pressure on the other large energy firms like Electric Ireland, Bord Gáis Energy and Energia, to follow suit with their own price cuts.
