Fixed energy plans for large businesses

Is your energy bill between £100,000 and £1m?

Set the unit price and standing charge of your energy for the length of your contract, which could be up to 5 years.

Many large businesses fix their energy prices for the following reasons:

Improved cost certainty. You know what your prices are for however long you agree
Simple to manage. Less administration compared to flexible price contracts
Peace of mind. Giving you confidence in budget projections

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 therm 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.
