The Daily Charge That Undermines a Competitive Unit Rate

The annual energy budget is usually approved with a sharp focus on pence per kilowatt hour. That is understandable: unit rates are visible, comparable and easy to present to a board. Yet for many UK organisations, the fixed daily charge on each electricity and gas meter is the line item that quietly decides whether a seemingly competitive contract is actually good value.

As winter 2026/27 approaches, procurement teams will be tested on all-in cost rather than headline rates. Standing charges deserve the same scrutiny as unit rates, particularly across multisite estates where small daily differences multiply by meters, fuels and days.

Why the daily charge matters more than it appears

A standing charge is the fixed amount a business pays each day for each meter, regardless of how much energy it uses. Depending on the contract, it can recover supplier fixed costs, meter rental and data services, and elements of network or policy costs. The exact composition varies by supplier and contract, which is why a single pence-per-day figure can be misleading when compared without a breakdown.

The commercial effect is straightforward. A site that runs reduced shifts, closes for Christmas or has low base load still pays the daily charge. A vacant unit can continue to attract fixed costs until the meter is dealt with. A low unit rate paired with a high standing charge may look attractive in a tender summary but lose on an all-in basis at the consumption level the business actually expects.

Regional variation adds another layer. Electricity standing charges reflect, among other things, the distribution network operator area and the way network costs are recovered. Meter type matters: half-hourly, non-half-hourly and advanced meter arrangements can carry different fixed and data costs. Capacity, particularly for half-hourly electricity, may be charged separately through agreed kVA. Supplier risk, contract length and site-specific factors can also influence the final figure. Business energy is not subject to the domestic default tariff cap, so there is no single universal benchmark to rely on.

Step one: build a site-level register

Start with a register rather than a supplier summary. For each site, record the MPAN or MPRN, address, fuel, distribution area, meter type, agreed capacity where relevant, supplier, contract end date, standing charge in pence per day, unit rate in pence per kWh, annual consumption and any pass-through or policy costs shown separately.

Use twelve months of bills and the current contract schedule. Include vacant sites, landlord supplies and sites that are about to be transferred. Normalise the standing charge to an annual figure by multiplying the daily rate by 365. That simple step makes sites comparable and exposes outliers that a monthly invoice total can hide.

Step two: separate standing charges from capacity and pass-through costs

A common audit error is to treat every fixed-looking charge as a standing charge. For half-hourly electricity, the capacity charge is based on agreed kVA and is distinct from the daily standing charge. Meter rental, data collection and pass-through items may also appear separately. Ask the supplier for a line-by-line breakdown of the offer and the invoice.

This matters at renewal. If a site has reduced its operations, the agreed capacity may now be too high. Reviewing capacity is not a substitute for reviewing the standing charge, but the two should be examined together. For gas, check the annual quantity and meter read arrangements, because estimated reads can obscure the true fixed cost pattern.

Step three: test the contract mechanics

Standing charges can be fixed for the contract term or subject to change, depending on the terms. Check whether the daily charge is guaranteed, how it is treated at renewal, and whether site amendments or meter upgrades trigger a new rate. Look for auto-rollover language, notice periods and deemed rates if a renewal is missed.

A supplier may present a market-leading unit rate while recovering margin through the daily charge. That is not necessarily poor value, but it must be visible. Compare offers on the same consumption assumptions, the same contract length and the same pass-through assumptions. A like-for-like comparison is the only defensible negotiation position.

Step four: build the negotiation case

Aggregate the estate before approaching the market. A portfolio with several meters and both fuels gives a buyer more levers than a single-site renewal. Ask each supplier for the standing charge breakdown, the annual fixed cost at current meter numbers, and an alternative structure with a different balance of unit rate and daily charge.

Use the register to show where consumption has fallen, where sites have closed and where capacity is excessive. Request a reassessment where the evidence supports it. Keep the conversation on all-in cost: annual unit cost plus annual standing charges plus capacity and pass-through costs. That framing prevents a low headline rate from dominating the discussion.

Step five: govern the contract after signature

The audit does not end at signature. Check invoices quarterly against the contract, confirm that new sites are added on the agreed terms, and remove vacated sites from the register when the meter arrangements allow. Set renewal reminders at least six months before contract end, and again before any notice deadline.

ExEnergy's view is that standing charges should be treated as a portfolio line item, not an administrative detail. In 2026, with budgets under pressure and winter 2026/27 renewals approaching, the organisations that control fixed daily costs will be better placed to judge whether a competitive unit rate is genuinely competitive.
