This page gives a snapshot of how ‘standard variable’ rate tariffs (SVTs) compare on average by supplier and against the cheapest available tariffs.
These figures represent a typical dual fuel customer paying by direct debit and with typical consumption. The pricing information refers to a representative snapshot taken on 28 November 2016 and should not be used as a price comparison tool. To access accredited price comparison sites, see Compare gas and electricity tariffs.
For figures on the number of SVT accounts and price differentials from April 2017, please see the Ofgem Data Portal. We now publish this data alongside our retail market indicators. Please note the information on this page uses a different methodology to our more recent figures. We explain what's changed in the methodology below.

What is a 'standard variable' tariff?
A standard variable tariff is a supply contract with an indefinite length that does not have a fixed-term applying to the terms and conditions. It’s an energy supplier’s basic offer. If a customer does not choose a specific energy plan, for example after their fixed tariff ends, they are moved to an SVT until they choose a new one. A customer can also make an active choice to select an SVT.
Our data shows that standard variable tariffs are usually more expensive than other deals available in the market. As of October 2016 around 19 million domestic energy accounts (15 million paying by non-prepayment methods) are on SVTs and are potentially missing out on significant savings on their bills compared to cheaper tariffs from their existing or another supplier.
