Don't pay over the odds for gas and electricity! We list the cheapest deals.
Energy users are split into low, medium and high. Energy regulator Ofgem defines a medium user as using 13,500 units of gas and 3,200 units of electricity a year. Read how to work out your energy usage.
Gas and electricity tariffs are either variable - where prices change in line with the cost of energy - or fixed - where prices are guaranteed for a set period of time.
Here are the cheapest variable and fixed tariffs for a medium energy user, paying by direct debit.
Energy best-buy tables explained
While best-buy tables are good as a guide, it's important to remember that energy prices will vary based on where you live and how much gas and electricity you use.
Dual fuel tariffs are often cheapest but it's worth adding up the cost of taking separate gas and electricity deals as this can sometimes work out cheaper.
Small energy suppliers
We're all familiar with the UK's big six gas and electricity suppliers - SSE, npower, British Gas, Scottish Power, EDF and E.ON.
However, there are a number of smaller suppliers in the UK, as you can see by some of the less familiar names in the best-buy table above.
But don't let the unfamiliar names put you off getting a good deal.
These smaller firms supply the same gas and electricity as the big six and all adhere to industry rules, such as answering to energy regulator Ofgem.
Alex Webb, head of gas and electricity at Confused.com, says: "It pays to look for the best deal, not just the name, when it comes to trying to get the best deal on gas and electricity."
