If you use very little gas and electricity, or have a second home that isn't occupied all year round, your tariff's standing charge means you might be overpaying for energy.
You can cut your energy costs by paying a very low standing charge or even finding a tariff without one, if you know where to look. That's where we come in.
We've analysed hundreds of gas and electricity tariffs to find which ones are cheapest if you use little energy, plus which ones have no standing charge.

What is a standing charge?
Most energy tariffs are made up of two parts:
Standing charge - a fixed amount paid daily
Unit rate - the price you pay per unit (kilowatt hour; kWh) of gas or electricity you consume.
Usually, you'll have separate standing charges and unit rates for gas and electricity. Your total unit rate cost depend on how much energy you use. But you pay the standing charge every day, regardless of whether you use any energy.
So if you use very little energy, or your second home is vacant for large parts of the year, you'll still be paying the standing charge every day. This adds up over the course of a year, and makes up a significant chunk of your bill if you use little energy.
British Gas standing charge
British Gas's standing charge on its standard variable deal is 26.01p per day for both electricity and gas. So you'll pay £190 per year even if you don't use any energy.
British Gas's standing charge isn't the priciest, though - Scottish Power's adds up to £200 per year.
How to pay no standing charge
Some energy deals have very low standing charges, and a few have none at all. 'Zero' standing charge, or tariffs which just have a unit rate, can be ideal for low energy users.
The following energy tariffs have no/zero standing charges. Click on the company name to see how it fared in our energy company satisfaction survey:
E EnergyReward Smart Oct 2017 is a variable-price tariff available to prepayment customers only. It doesn't have an exit fee to leave.
Ebico's Zero tariff is a variable deal from this not-for-profit supplier. It's not available to those with prepayment meters.
Eversmart Energy's Goodbye Standing Charge does what it says in the name. It's a fixed-term tariff but has no exit fees.
Extra EnergyVariable Price v2 is a variable-rate tariff with no exit fees. Extra Energy didn't compare well in our latest energy survey, based on its customers' feedback.
Solarplicitysays that there are no standing charges on any of its tariffs, fixed or variable. It offers 100% renewable electricity.
Utilita's tariffs for prepayment meters are without standing charges. However, its Premium Energy tariff charges 40p for the first 1kWh of electricity used per day, 30p for the first 1kWh of gas used per day, and a much lower rate for subsequent units (of kWhs) used. The first unit's rate is pricier than the daily standing charge on other companies' tariffs.

Five things not to forget if your home is left empty
If you own a second home that's often unoccupied, or spend lots of time away from home, follow our tops tips to keep your home safe, secure and energy efficient.
Make your home look occupied, even if it isn't. Permanently closed curtains or piles of unopened post on the mat can reveal that no one's home. Ask a neighbour to sort the post and to turn on the occasional light.
Easily accessible windows should be double-glazed, ideally, and have locks that secure to the frame.
Doors and frames should be solid, at least 4.4cm thick and fitted with a five-lever mortise deadlock. Doors with glass panels can be fitted with laminated glass or glazing film for extra protection.
If the weather is cold when your home is empty, use the 'frost' setting on your thermostat or set the heating to come on for a couple of hours (at a low temperature) each night to prevent damage from freezing.
