How to Compare Business Energy Quotes

Comparing quotes is arithmetic, not alchemy. You are lining up the same three ingredients every time: how many kilowatt-hours you expect, the pence-per-kWh stack, and everything else that bills monthly before VAT. Skip one layer and the “cheapest” PDF wins even when it costs £3k more per year.

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

  • Normalise every offer to £/year ex VAT using the same annual kWh—usually the last four quarters of billed consumption, not a broker guess.
  • Standing charges matter: £1.20/day is £438/year before you turn anything on.
  • Ask if Climate Change Levy is included; at main rates it is material (order-of a little under 1p/kWh for electricity—see HMRC tables for your year).
  • Highlight passthrough lines from pass-through contracts so DUoS swings do not ambush you mid-term.
  • Broker uplift belongs in the model—see TPI brokers explained.

Build one master spreadsheet tab

Columns we use with clients: supplier, product name, contract months, commodity p/kWh, standing £/day, pass-through flags (Y/N), CCL included? (Y/N), REGO adder if any, broker fee p/kWh, security deposit, exit fee reference. Feed a single cell with annual kWh—for example 48,000—and let formulas output subtotals. That stops the classic error where Offer A at 25.2p beats Offer B at 26.1p while B’s standing charge is 95p/day cheaper and includes CCL.

Worked contrast: Nottingham office on 38,000 kWh

Quote 1: 25.4p/kWh, 320p/day standing, 36-month fix, CCL quoted on top using HMRC’s published main electricity rate for their tax year. Quote 2: 26.0p/kWh “all-in commodity + CCL”, 260p/day standing. Annual commodity+calc line for Quote 1 lands near £9,652; Quote 2 near £9,884—Quote 1 wins on numbers. Flip standing charges to 420p versus 240p and Quote 2 suddenly wins by £657 despite the higher unit rate. That is why café owners glaze over when salespeople yell “we’re a full penny cheaper.”

Table: line items to insist on in every quote pack

Line Why it skews comparisons
Meter operator chargeSometimes bundled, sometimes separate—match your current bill.
Data collector / agentHH sites may pay £5–£25+/month depending on service level.
FiT / CfD levelisationOften passthrough—confirm p/kWh band.
Renewal basket labelCheck it is not a rollover schedule in disguise.

Market timing without becoming a trader

Quotes reference forward curves when desks hedge. If NBP gas futures jump 8% between Monday and Thursday, two “identical” verbal holds diverge. Date-stamp PDFs and reject stale screenshots. For a longer methodology on drivers, read how business energy prices are set; pair with understanding unit rates so your team shares vocabulary.

Quality checks before you countersign

  • MPAN last digits match the bill header you used for kWh.
  • VAT rate stated (20% standard vs 5% reduced domestic-type cases).
  • Contract start aligns with termination notice served on the incumbent.

Scenario weighting: do not let one outlier month pick your tariff

Procurement teams sometimes anchor on the last invoice kWh, which is dangerous after a mild winter or a maintenance shutdown. Build a trailing-twelve-month profile plus a forward scenario (+/−10%) and label each quote with the consumption band you used. If Quote A wins at 95,000 kWh but Quote B wins at 105,000 kWh, the “right” answer depends on capex you already approved—document the assumption explicitly in the approval email so auditors see diligence, not guesswork.

Where day/night splits exist, weight registers using actual cumulative reads, not rule-of-thumb percentages. A 2p/kWh swing on the night register is irrelevant if only 18% of kWh land there; the same swing on an 85% night load (storage chill) dominates. Export a pivot with month, day kWh, night kWh, and blended average before you accept a broker summary.

Finally, compare total cost including standing charges, CCL at the correct year rate (electricity main rate £0.00775/kWh for 2025–26 unless you qualify for relief) and realistic VAT. A spreadsheet that stops at commodity p/kWh is how finance directors get surprised in month ten when DUoS passthrough posts.

Name a single owner for version control: when five people forward partially redacted tariffs, someone inevitably mixes a 36-month quote with a 24-month acceptance. A one-page summary table—supplier, term, unit, standing, fees, exit terms, date issued—stops that failure mode cold.
