Standing Charges on Business Energy
The standing charge is the quiet second half of your tariff: pence per day before you have bought a single kWh. On UK non-domestic contracts it often bundles metering service, supplier overheads and margin on the fixed slice of retail—so “cheapest unit rate” leaderboards regularly mis-rank real annual cost.
Next step: If you use under about 50,000 kWh a year, you can get a quote in under 90 seconds online — fast, no obligation. Larger supply, half-hourly metering, or prefer chat? Use the contact page.
Key takeaways
- Annualise fast: 120p/day is roughly £438/year before VAT—compare that to any “saving per kWh” you think you negotiated.
- Low-use pain: seasonal traders, storage units and small workshops hit breakeven quirks first; model total £/year, not p/kWh alone.
- Contract text beats PDF marketing: confirm whether standing is fixed for the term or referenced to a price book on flexible products.
- Bill QA: standing days must match the invoice calendar (28-, 30-, 31-day months; leap years add one free-standing day).
What your p/day is really covering
Commodity p/kWh pays for energy as it flows; standing charges recover costs that exist even at zero consumption—running a billing platform, credit cover, metering communications, central switching admin and a slice of supply-chain staff time. Networks recover the bulk of allowed revenue elsewhere (unit rates on smaller connections, DUoS/kVA bands on larger ones), but what you see on a SME bill as “standing charge” is almost always a retail line item rather than a transparent pass-through of a single regulatory label.
Domestic tariffs now expose cap building blocks more clearly; business bills remain UX-lumpy. That does not give suppliers permission to hide markup—it simply means you must rebuild the economics: multiply usage by unit rate, add standing days times daily rate, then layer CCL and VAT exactly as your contract states. Our bill reading guide walks the reconciliation.
Turn “pence per day” into pounds per year
Quick mental maths anchors:
- 50p/day ≈ £182.50/year
- 150p/day ≈ £547.50/year
- 250p/day ≈ £912.50/year—on only 5,000 kWh that is already 18.25p/kWh of effective fixed cost before you price the electrons.
As annual kWh rises, that fixed wedge spreads thinner. Two tariffs with identical headline unit rates therefore favour opposite sites if their standing charges diverge by even 40–50p/day. Pair this thinking with unit rate mechanics and quote comparison.
Scenario table: when “higher unit + lower standing” flips the winner
Illustrative annual commodity + standing only (ignore CCL/VAT). Tariff A: 28p/kWh, 90p/day. Tariff B: 26p/kWh, 160p/day. Standing over a year uses 365 days.
| Annual kWh | Tariff A total | Tariff B total | Cheaper |
|---|---|---|---|
| 8,000 | £2,568.50 | £2,664 | A |
| 20,000 | £5,928.50 | £5,784 | B |
| 45,000 | £12,928.50 | £12,284 | B |
Breakeven sits between the low- and mid-thousands of kWh for these illustrative numbers; your real crossover shifts with each quote. Export a spreadsheet row per MPAN with columns for unit, standing, expected kWh bands (low/base/high case) before you sign.
Half-hourly sites and “extra fixedness”
Larger HV/LV supplies may show higher apparent standing fees because data collection and settlement services cost more to run. That is different from agreeing a new capacity band: if DUoS or kVA-related lines jump, treat it as a network-agreement review (capacity charges), not something a standing-charge haggle alone will unwind.
Mini audit checklist before renewal
- Copy the standing line from your current bill; multiply by billing days—does it equal the subtotal before VAT?
- Repeat for the renewal PDF at low, expected and high annual kWh.
- Ask explicitly whether metering or MOP charges sit inside standing or are itemised elsewhere.
- If a broker proposes “same unit rate,” demand the standing row anyway—TPIs sometimes optimise one lever; see TPI brokers explained.
Seasonal cash-flow: why December feels expensive
Standing charges accrue by calendar day even when the workshop shuts between Christmas and New Year. If your business closes for 14 days but keeps the supply energised, you still pay those daily pence—budget them into silent weeks so cash forecasts do not blame “mysterious” January invoices. Where feasible, discuss temporary disconnection with your DNO and supplier; the admin cost only makes sense for long idle periods, not a fortnight.
Standing plus minimum-quantity clauses occasionally interact: some flex deals guarantee a floor kWh; missing it can trigger makeup charges that resemble standing hikes. Read schedule footnotes slowly; if language references “take-or-pay,” model the penalty exactly as you would commodity risk.
