Business energy standing charges explained

A standing charge is a fixed daily fee on your business electricity or gas bill, charged regardless of how much energy you consume. It covers the cost of maintaining your meter, your connection to the network, and a share of supplier administration costs, and it applies even in months where consumption is very low.

Standing charges for business electricity typically range from around 25p to 60p or more per day, and for gas typically from around 20p to 40p per day, though the exact figure depends on your region, meter type and supplier. Larger or half-hourly metered sites can see different structures again, sometimes including a separate capacity charge on top.

The charge exists because a supplier and network operator incur costs simply by having your meter connected and readable, independent of consumption: meter maintenance, standing infrastructure, billing systems and account management. These costs do not disappear if your business closes for a quiet month, so they are recovered as a flat daily fee rather than folded entirely into the unit rate.

Standing charges matter most for low-consumption businesses. A small office using very little electricity can find that the standing charge makes up a large proportion of its total annual bill, sometimes more than a quarter, which means a slightly lower unit rate with a much higher standing charge can end up more expensive overall.

Worked example: a business using 5,000 kWh a year at 30p per kWh with a 45p daily standing charge pays £1,500 for commodity and £164.25 for the standing charge, a total of £1,664.25. A competing quote of 27p per kWh with a 70p standing charge comes to £1,350 plus £255.50, totalling £1,605.50, which is actually cheaper despite the far higher standing charge, purely because the unit rate saving outweighs it at this consumption level.

This example shows why comparing standing charges in isolation, or unit rates in isolation, can both mislead. The only reliable comparison method is to calculate the full annual cost for each quote using your actual consumption.

Some suppliers offer a nil or reduced standing charge with a correspondingly higher unit rate, which can suit businesses with very low or seasonal consumption, such as premises that close for part of the year, but tends to cost more overall for businesses with steady, higher usage.

Standing charges are typically not negotiable in the way supplier margin within the unit rate can be, since a meaningful share reflects genuine fixed network and administration costs, though the total still varies enough between suppliers to be worth comparing.

For half-hourly metered businesses, a separate capacity charge may apply alongside the standing charge, covering the maximum demand level agreed with the network. Checking whether your agreed capacity matches your actual peak demand is worth doing at renewal, since oversized capacity is a common source of avoidable cost.

When reviewing any new quote, always ask for both the unit rate and the standing charge in writing, and run the annual cost calculation yourself using your real consumption rather than relying on a supplier's own comparison summary.

It is worth checking whether your standing charge has changed at your last two or three renewals even if your unit rate has stayed broadly similar, since some suppliers adjust the balance between the two components between contracts in ways that are easy to overlook if you only ever glance at the headline pence-per-kWh figure on a renewal letter.

For businesses with multiple low-usage meters, such as a retail chain with several small stores, the cumulative effect of standing charges across the portfolio can be a genuinely significant annual cost even though no single site's bill looks alarming in isolation, which makes portfolio-wide review worthwhile rather than assessing each site purely on its own numbers.

The standard 20% VAT rate applies to most standing charges as part of the overall bill, though the same reduced 5% rate that applies to low electricity or gas consumption also covers the standing charge element when a business qualifies. The Climate Change Levy, by contrast, is charged only on units consumed, not on the fixed daily fee itself.

Standing charges scale less obviously with business size than unit rates do: a single-till shop and a small trade counter might sit on a broadly similar daily fee even though their total consumption, and therefore their overall bill, differs by a factor of five or more once actual usage bands from 5,000 kWh up to 75,000 kWh and beyond are taken into account.

Whatever type of premises you run, the notice window in your contract is what determines how much runway you have to shop around before the standing charge and unit rate simply roll over onto a fresh, often less competitive, set of terms. Mark that date the day you sign, not the week before it matters.
