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.

Customer for 20 Years

I have been with Utility Warehouse for 20 years for energy, landline, broadband, landline and 16 years for mobile. I also use their cashback card, so get (I think) the maximum discounts available from them. I have always found the customer service excellent when I have called them for help. I find it really useful that all my individual utility statements are wrapped up in one monthly statement. I generally find when frequently encountered by competitors touting for business outside supermarkets, that as soon as I mention I have all the UW services including the cash back card that they back off, so that indicates for me that I am getting good value for money. I'm sure I might be able to beat the price slightly by shopping around but the time and effort it involves to enquire with different providers and deal with different emails/statements isn't worth it in my opinion.
