Energy standing charges in the UK: why you pay per day before using any units
What electricity and gas standing charges are, how they affect your bill, and how to compare tariffs fairly—including dual fuel and low-usage homes.
If you have ever looked at a UK energy bill and wondered why you owe money before turning the kettle on, you have met the standing charge. Here is a straightforward explanation you can use when comparing tariffs—with or without a Doorstep Savings visit.
What is a standing charge?
A standing charge is a fixed daily fee from your supplier, covering costs associated with supplying your home—such as network maintenance, metering, and regulatory obligations—before you consume any energy.
It appears separately from your unit rate (the pence per kilowatt-hour, kWh).
Your bill is broadly:
(Standing charge × number of days) + (Unit rate × kWh used) + VAT (and any other agreed charges)
Why two similar tariffs can feel different
Two deals might advertise the same pence per kWh but different daily standing charges. For a low-usage household, a higher standing charge can hurt more than a slightly higher unit rate. For a high-usage home, unit rates often dominate.
When comparing:
- Write down electricity standing (p/day) and gas standing (p/day)
- Multiply by 365 for a rough annual “fixed” component
- Add estimated kWh × unit rate for each fuel
A doorstep helper can help you do this on paper with your numbers so it is not abstract.
Electricity vs gas
You usually have separate standing charges for electricity and gas. Dual fuel tariffs still break these out on statements—even if you pay one direct debit.
Prepayment and smart meters
Standing charges still apply on many prepayment meters—they may be taken as a small daily deduction before credit goes to units. Smart meters do not remove standing charges; they just measure usage more frequently. Always read the tariff summary for your meter type.
“No standing charge” deals
Occasionally you will see marketing around low or zero standing charges. Often the unit rate is higher to compensate. The only fair comparison is total cost for your usage profile over a year (or the contract term).
Questions to ask
- What is the daily standing charge for electricity and gas on this tariff?
- What are the unit rates after any discount period ends?
- Are there exit fees or minimum terms?
- Does this tariff apply to my meter type and payment method?
