Fixed energy plans for large businesses

Simple plans, price guarantees

If you choose one of our fixed price plans, you'll be able to guarantee the unit cost of business gas and electricity for the length of the contract.

You decide the length of the contract - anything from a couple of months to five years. Many large businesses fix their energy prices for the following reasons:

Knowing what they'll pay for gas and electricity can help with budgets
The fixed price protects a business from changes in wholesale energy costs
Simple, fixed contracts can help them find energy efficiencies

If your business operates across multiple sites, it's possible either to apply an average price or to opt for bespoke, site-specific energy prices.

We have three flexible contracts for you to consider:

Full flexibility contract	Monthly block for gas contract	Gas cash out contract
Our full flexibility plan is available if your business uses more than 10 gigawatt hours (GWh) of electricity a year.	If your business uses over 100,000 therms of gas a year, you might want to consider our monthly block for gas plan.	Our gas cash out plan allows you to buy gas up front and pay specific balancing costs instead of an average balancing premium.
It allows you to buy and sell energy whenever you choose, meaning you could take advantage of real-time market prices.	This allows you to buy blocks of gas as you need them – choosing to buy in advance may help you budget more accurately.	This flexibility means you can monitor your own forecast and refine your position before your supply starts.
If you want to cut the amount of time you spend on this, you can set target prices for when you trade energy.	You can float your volume and get market-reflective rates for a longer period of time.	You’ll be able to use transparent pricing to buy energy for the upcoming month.
Any unpurchased energy will be procured using the day ahead default mechanism (Heren for gas, LEBA for electricity).		You can also monitor the number of your transactions and their financial effect, plus the volume left to fix between your purchase and estimated consumption.
