Fixed energy supply

Lock in rates, control your costs, and plan ahead with confidence.

At a glance

The energy market is constantly changing - and not always to your schedule. Natural disasters, political instability, or shifts in global demand can cause costs to jump overnight. Locking in a fixed price for electricity and gas shields your business from volatility, giving you the confidence to pursue growth without the threat of unexpected charges.

How a fixed contract works

A fixed energy contract locks in the price you pay per megawatt-hour (MWh) for a specific period. This means the price per unit of energy you consume won’t change during your contract, protecting you from market price fluctuations.

Your energy unit rate is made up of two parts:

Commodity
The wholesale energy cost, which can be fixed at the time of purchase for a specific length of time.
Non-commodity
Non-commodity charges that cover renewable levies, network costs and future generation investment, which can be fixed or passed through at actual cost.

Why choose a fixed contract?

Consistency

No surprises, just stability. A fixed contract provides your business with a clear, predictable cost structure – making it easier for you to manage finances, plan for the future, and allocate resources efficiently.

    Simplicity

    Low touch, high clarity. If you want simplified energy management and minimal interaction with the wholesale market, a fixed contract allows you to spend less time tracking energy trends and more time running your business.

      Protection

      Stay on track in the face of market swings. Fixing your energy prices protects your operations from wholesale price shifts, so no matter how the trading landscape fluctuates, your energy rates stay the same.

        Control

        Fixed doesn’t have to mean inflexible. Our contracts can be tailored to different lengths, so whether you want a short-term buffer against volatility or prefer a longer stretch to lock in lower rates, you can control the contract to align with your objectives.

          Should I fix my energy supply?

          A fixed energy plan is ideal for small or medium-sized businesses looking for the freedom they need to pursue their ambitions – knowing their rates won’t change.
          Consider a fixed energy contract if:

          1.

          Your average monthly or annual energy consumption is steady and predictable

          2.

          Your energy usage is stable rather than highly seasonal or variable

          3.

          Price certainty is important for your budgeting and forecasting processes

          4.

          You lack the in-house expertise to manage market risks or make complex hedging decisions that more flexible contracts might require

          FAQs

          A fixed energy supply contract locks in your unit price for electricity or gas for the duration of the agreement. This provides cost certainty and protection from market price increases, making budgeting easier.

          A variable energy supply contract, by contrast, tracks wholesale market rates. Your price can go down if the market falls, but it can also rise when prices increase.

          With a fixed contract, you have two options:

          • Pay a fixed price for the non-commodity charges to keep your bills predictable and simplify budgeting.
          • Choose pass-through pricing, where you pay the real costs as they come. With pass-through, you get full visibility of what you’re paying for, which can help you make smarter, more data-driven decisions about your energy use.

          Yes, we offer renewable fixed energy supply. With our fixed price contracts, you can choose renewable energy backed by green certificates, or opt for a conventional fuel mix if you prefer. The choice is yours.

          Energy needs can shift. That’s why our fixed contracts include flexible volume tolerance options. You’ll have a built-in buffer, so if your usage goes slightly above or below your forecast, you won’t be hit with a surprise bill.

          Renewable supply

          No matter how you purchase your energy – fixed, flexible, or somewhere in between – you can still power your business with 100% renewable electricity and low-carbon gas.

          Flexible supply

          Flexible electricity and gas contracts give you the freedom to adapt as markets change. Hedging options let you spread purchases across monthly, quarterly, or seasonal periods, while product features such as volume tolerance provide certainty on how your consumption is managed within the contract.
