Here are some common terms you’ll see on your energy bill, and what they mean:

Tariff Comparison Rate (TCR) — Introduced by Ofgem in 2014, a TCR is energy’s answer to the credit card market’s Annual Percentage Rate (APR). In other words, it’s designed to provide an indication of how your plan’s unit rates for gas and electricity compare to other plans on the market. Read more about Tariff Comparison Rate here.

Fixed Rate — A fixed rate is just that: it means your rate cannot be changed by your supplier before your plan’s end date. You can get a fixed rate plan for one, two or three years. Find out more about fixed rate plans, including how they work and the current cheapest fixed rate plans.

Variable Rate — The opposite of fixed rate plans, variable rates are often what supplier’s use for their standard plans. This means that if the supplier announces a price rise, your energy costs will go up.

kWh — A kilowatt-hour or kWh is a name given to a unit of energy, and it is the standard unit across suppliers for both gas and electricity. One kWh will provide enough energy to power a 100-watt lightbulb for 10 hours.
