Many businesses operate on multiple sites and locations. Traditionally, this would mean that they needed to have an energy account and a business energy meter for each of their locations. They would also need to have multiple renewal dates with different suppliers, rather than one renewal date.
Businesses that operate on several sites would usually need to collate their energy bills in order to find out how much they are paying overall.
A multi site energy meter measures all the sites at the same time. It then combines those potentially time consuming readings for business gas and business electricity into one. This means that you can have one account and one bill for all of your locations.
