What Is a Standing Charge on an Energy Bill?

At a glance

  • A standing charge is a daily tariff charge, separate from the price of each kWh used.
  • Where your tariff has one, it normally applies even on days when consumption is zero.
  • Compare the standing charge and unit rate together using your expected consumption.
  • Household and business arrangements differ. Empty premises and solar panels do not automatically remove the charge.

Using less energy can reduce your consumption charge while leaving another part of the bill almost unchanged. That fixed part is often the standing charge. Understanding both prices helps you compare tariffs and check bills without confusing energy use with the cost of maintaining an active supply.

How the daily charge works

A tariff might specify a standing charge of 50p per day. Over 30 days that adds £15; over a 365-day year it adds £182.50. These figures illustrate the calculation and are not current quoted rates.

If you have separate gas and electricity supplies, check the charge for each. A dual-fuel bill can contain two standing charges. Some tariffs use a different pricing structure, so read the actual terms rather than assuming every tariff has the same type of charge.

Ofgem’s explanation of standing charges describes their relationship to unit rates and the domestic price cap. The charge is not simply a fee for the amount of energy you used that day.

What the charge contributes towards

Suppliers recover a range of supply costs through tariff prices. These can include network, metering, operating and policy-related costs. The split between a daily charge and a unit price is part of the tariff structure; the standing charge is not a personalised itemised invoice for the pipes outside your home.

Prices can differ by fuel, region, payment method and tariff. To check current capped household rates, use Ofgem’s regional unit-rate and standing-charge information, rather than a national headline or an old example.

Why low-use households notice it more

Suppose a tariff has a £180 annual standing charge. If consumption charges are £180 too, the standing charge represents half that combined amount. If consumption charges are £1,800, it is a much smaller share.

This does not mean reducing consumption is pointless. Each avoided kWh can still reduce the consumption charge. It means the total bill will not necessarily fall by the same percentage as energy use.

Keeping the same tariff and halving consumption normally leaves the daily charge unchanged. Separate these effects when measuring the result of an energy-efficiency improvement.

Compare the total cost of a tariff

For a straightforward single-rate tariff, estimate:

Annual consumption × unit rate + daily standing charge × days supplied

Use prices on the same VAT basis and include relevant fees. For multi-rate tariffs, calculate consumption at each rate separately. If you have both fuels, calculate both.

For example, assume two tariffs with prices stated on the same tax basis:

  • Tariff A: 25p/kWh and 60p/day.
  • Tariff B: 28p/kWh and 30p/day.

At 2,000 kWh over 365 days, A costs £500 + £219 = £719. B costs £560 + £109.50 = £669.50.

At 5,000 kWh, A costs £1,469, while B costs £1,509.50. The cheaper option changes because the balance between the fixed and variable charges changes with consumption. These are illustrative tariffs, not offers.

Where a tariff has no standing charge, check whether it uses a higher unit rate, minimum charge or other condition. A zero daily figure does not itself establish the cheapest total cost.

Empty homes, solar panels and unused supplies

An empty property can still have an active supply and an account holder responsible for its charges. Switching appliances off is different from ending a supply agreement or arranging physical disconnection.

Solar generation may reduce the electricity you import, but it does not automatically remove charges under your import tariff. Export payments are a separate arrangement.

If a supply is genuinely no longer needed, ask the supplier what ending the account or disconnecting would involve, including responsibility, fees and possible future reconnection. Do not remove, alter or disconnect metering equipment yourself.

When moving, establish the dates for which you are responsible and provide readings. See our moving-home checklist.

Prepayment and household price protection

On a prepayment account, a standing charge can continue to accrue when you use no energy. Some of a later top-up may cover accumulated charges or other deductions rather than all becoming available for new consumption.

Ask the supplier to explain the deductions if the amount available looks wrong. Ofgem explains help with prepayment meters, including what to do if you cannot afford to top up.

For eligible household default tariffs in Great Britain, the price cap constrains tariff pricing. It does not turn the advertised typical annual figure into a maximum bill for every home. Fixed deals and business accounts need separate consideration.

Business standing charges

Business contracts can include daily charges alongside unit prices and, for some electricity supplies, capacity or other site-specific charges. Do not assume a domestic comparison covers every business bill component.

Check the contract’s charge names, calculation periods and any pass-through provisions. A daily charge described differently by another supplier may not cover the same things. Compare a full expected-year cost on a consistent basis.

If a standing charge seems wrong, compare the tariff agreement with the bill, check the number of days and ask for an explanation in writing. A general educational guide cannot establish the correct contractual charge for an individual site.
