If you’re looking for a new electricity deal, you’re not alone: 319,000 electricity customers switched energy supplier during January 2018, according to OFGEM*. Shopping around for the best electricity deal is simpler than you might think – but there are bound to be a few questions. Here’s everything you ever wanted to know about comparing electricity deals.

Residential real-time pricing customers pay electric supply prices that vary by the hour. To make a meaningful comparison between variable RRTP rates and RES offers, customers should compare their past electric supply cost savings from the total Electric Supply section of the bill, provided by their RRTP provider, with an electric supply cost savings estimate provided by RESs. Alternatively, customers can compute their average real-time hourly price in cents per kWh (each month the average real-time price is equal to the total of the Electric Supply section of the bill divided by the monthly kWh) to compare with RES offers posted in cents per kWh. Customer should bear in mind, however, that because RRTP rates vary over time, past savings do not predict future savings, but only serve as a guide to compare past performance.
