Not every tariff suits every household. Understanding the 6 main tariff types takes under 3 minutes and could save you hundreds of pounds every year.
Locks your unit rate and standing charge for 12, 18, or 24 months. Your rate does not rise even if Ofgem increases the price cap. Exit fees apply (typically £50 to £100 per fuel) if you leave early. Best for: households who want price certainty and want to beat the next price cap rise.
The default tariff when a fixed deal expires. The unit rate follows the Ofgem price cap, which changes every quarter. No exit fees, but you pay the maximum capped rate. Best for: short-term flexibility only. Not recommended when the cap is forecast to rise.
Both your gas and electricity come from one supplier on one bill. Dual fuel deals are sometimes, but not always, cheaper than two separate contracts. Switch compares both options and shows you the true combined cost. Best for: simplicity and potential small discount.
Green tariffs match your electricity with energy from certified renewable sources, wind, solar, and hydro. 100% renewable electricity tariffs are widely available. Fully green gas (biomethane) is rarer and more expensive. Best for: environmentally conscious households.
Requires you to top up a smart card, key, or token before using energy. These tariffs cost about £180/year more than direct debit tariffs. Switching away from prepayment is possible. Ask your supplier to install a credit meter at no cost if you have good payment history.
Charges different rates at different times of day. Economy 7 offers 7 hours of cheaper overnight electricity, useful for storage heaters or EV charging. Smart ToU tariffs (e.g. Octopus Agile) update rates every 30 minutes. Best for: EV owners and off-peak users. Requires a SMETS2 smart meter.
