Unit price
For homes with high heating demand, small differences in the price per kWh can materially change the annual cost.

What this energy solution helps you assess.
Current annual cost and the follow-on price reviewed together
Basic charge
This fixed amount is due regardless of consumption. Unit price and basic charge should always be calculated together.
Term and bonus
A new-customer bonus may help at first, but the price after the initial term is central to a fair comparison.
Heating outlook
CO2 pricing can raise gas costs over time. During renovation or heating replacement, alternatives such as a heat pump may also be discussed.

Frequently asked questions
A few answers before you enquire.
01When should I review a change of gas supplier?
That depends on consumption, unit price, basic charge and contract term. The follow-on price after the initial period matters, not only the new-customer bonus.
02Where can I find my gas consumption?
Your latest annual bill shows it in kWh. Consumption can vary substantially with floor area, insulation and heating habits, so the actual billing figure is the best starting point.
03What does CO2 pricing mean for gas customers?
CO2 pricing rises in stages and can make gas more expensive over time. If you are renovating or replacing the heating system, alternatives such as a heat pump can also be considered.
