What is a fixed energy tariff?
A fixed energy tariff means your unit price for gas or electricity is locked in for the duration of your contract, so you won’t be caught off-guard by any energy price hikes.
This means that regardless of changes in the energy market, your cost of energy per kWh and standing charge will stay the same.
Your monthly bill may increase or decrease depending on the amount of energy you use, but your unit price will be unaffected by any future price fluctuations.

Why choose a fixed energy tariff?
Guard against price changes
With our fixed energy tariffs, you can lock in your energy rate, shielding you from unexpected swings in the energy market. This means that no matter what happens, your unit rate stays the same, making it easier to manage your household budget.
Budget with confidence
One of the biggest advantages of our fixed energy tariffs is that you can budget with confidence. You’ll know exactly what you're paying for energy per kWh each month, which is ideal for keeping your finances on track.
Clear contract lengths
When you choose a fixed energy tariff, you also enjoy the assurance of a set contract length that fits your lifestyle and financial planning. Our fixed tariffs run for approximately 12 months, giving you stability with no surprises — you’ll know exactly when your rates are set to change, if at all.
Fixed vs variable energy: what’s best for you?
Not sure whether to go fixed or variable? Here’s the lowdown: while variable rates might offer savings when energy prices drop, choosing a fixed rate means your costs won’t jump up when the market changes.
Fixed energy tariffs | Variable energy tariffs |
|---|---|
Your unit rates and standing charge stay the same for the duration of your contract | Your unit rates and standing charges can go up or down depending on market conditions |
Your tariff has a fixed contract length, and you’re typically locked in for the agreed period | Variable tariffs are often open-ended with no set contract length |
If you want to leave your contract early, you’ll have to pay an exit fee | You’re usually free to leave a variable tariff at any time without facing early exit fees. |
