Notification of Gas Pass-Through Charges Change

As indicated in your gas supply contract, the gas charge within your tariff reflects your risk management approach e.g. fixed gas price, for the contract duration. In addition, as highlighted in the pricing proposal, SSE Airtricity gas supply contract provided for regulated pass-through charges and how these charges would be treated under the contract.

These “Pass Through Charges” are applicable third-party costs, charges, tax, duty, levy, tariff or any government imposed charge, relating to the supply and distribution of gas to the customer’s premises including, but not limited to, transportation and distribution charges and VAT.

Pass-through charges are used to pay for common services for all gas consumers and these charges are subject to regulatory approval. The changes in these charges apply to all suppliers equally.

The Distribution and Transmission Transportation pass-through charges for the 2018/2019 period applicable from 1st October 2018 have now been set and the impact of these changes on your current contract prices are set out below.
