How we find the cheapest gas for you
We only show tariffs available in your gas network area, then work out a yearly cost for each using your usage: the unit rate for each kWh, plus the standing charge, minus any discount or credit. The cheapest overall comes first.

Questions, answered
What are the gas network areas in Northern Ireland?
Northern Ireland's gas network is split into three areas: Greater Belfast, the Ten Towns and the West. Your gas bill shows which one you're in, and which suppliers you can choose depends on your area.
Which gas suppliers can I choose?
It depends on your area. In Greater Belfast you can choose between SSE Airtricity and firmus energy. Choose your area above and we'll only show tariffs available there.
Is gas charged per kWh?
Yes. Your meter measures gas in cubic metres, but your bill converts it to kWh and tariffs are priced per kWh. Use the kWh figure on your bill or annual statement.
How do I switch gas supplier in Northern Ireland?
Compare tariffs here, choose the one you want and sign up with that supplier. The new supplier arranges the switch with your current one. If you're on a fixed contract, check for an exit fee first, and have a recent meter reading ready.
Does the GB energy price cap apply in Northern Ireland?
No. Northern Ireland has its own energy market, regulated by the Utility Regulator, so the Ofgem price cap used in England, Scotland and Wales doesn't apply here. That's why NI prices need an NI comparison.
Estimates are a guide, worked out from the prices we've checked and the details you entered. The supplier confirms your final price and whether you're eligible.
