What’s the difference between a fixed and variable tariff?
Your unit rates and standing charges remain fixed for a predefined period of time. This is typically for a year.
This doesn’t mean that the amount you’ll pay is fixed – it depends on the amount of energy you use.
Fixed energy tariffs are available to customers who take all our services - energy, mobile, and broadband.
The cost you pay for your energy can go up and down in line with wholesale costs. We’ll always give you 30 days’ notice of any price changes.
