Fixed energy plans for large businesses

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

Flexible price contracts for large businesses

Buy all or part of your energy at any point before the month you use it.

The benefits:

  • Freedom. Take advantage of favourable movements in the market
  • Less vulnerability. Long term averaging of prices means you could be less susceptible to sudden price changes
  • Relationships. Through longer term partnerships we can help you to better control your energy spend
