How it works

Typically your home uses more energy in winter and less in summer. We equalise your consumption to give you a flat monthly rate, fixed for 12 months.

To apply, all we need is your current annual consumption for gas and electricity in kilowatt-hours (kWh). This information can be found on a recent bill or statement of account from your current supplier.

Payment must be made by monthly direct debit and you must receive paperless billing through our online account. We also ask that you provide monthly meter readings.
