How is my bill calculated?

Modified on Fri, 17 May 2024 at 03:43 PM

Your electricity usage is measured in Kilowatt Hours (KWh) and your gas usage is measured in MegaJoules (Mj). For each unit of energy usage your supplier will have a specific charge. The charges will vary depending on the total amount of energy that you use during the course of the year. Some charges also apply depending on the time of day that you use your energy, depending on which energy tariff you are on with your supplier. 
Our energy saving experts at Zembl have access to all the analytical tools they need to understand your energy costs. So when you speak to us, we can see how your energy usage compares across our range of suppliers to ensure that we put you on the cheapest tariff available.
