Almost half of the cost of electricity is overseen by the Utility Regulator, including NIE Network’s charges, various market charges and levies. These are the same for all suppliers who usually treat them as ‘pass-through.’ Some suppliers quote ‘energy only’ prices so make sure to include the pass-through charges when comparing offers.
