Comparing business electricity quotes properly means looking past the unit rate to standing charges, capacity and contract terms.
Comparing business electricity prices starts with recognising that the unit rate is only one part of the final bill. A genuinely useful comparison converts every quote into an estimated annual total using your real consumption, because standing charges, capacity charges and contract length can all move the ranking.
Before requesting quotes, pull your MPAN from a recent bill and check whether you are on a half-hourly or non half-hourly meter. This affects which suppliers can quote for you and how granular the pricing will be.
Gather at least twelve months of kWh consumption if possible, ideally with monthly detail rather than just an annual total, since some suppliers price more sharply for businesses with a flat, predictable load and less sharply for those with high seasonal peaks.
Request quotes across multiple contract lengths at the same time, since the cheapest term is not consistent across the market or across time. A one-year fix might be the best value in one quoting window and a three-year fix the best value a few months later, purely because of how the wholesale forward curve has shifted.
When quotes arrive, build a simple table: unit rate, standing charge, contract length, and estimated annual cost at your actual consumption. This turns a set of confusing rate cards into a single comparable number for each offer.
Worked example: a unit rate of 24p per kWh with a standing charge of 55p per day on 20,000 kWh annual consumption works out at £4,800 for the commodity element plus £200.75 for the standing charge, giving a total of £5,000.75 before VAT. Comparing this total, not the 24p rate alone, against a competing quote of 26p per kWh with a 35p standing charge, which totals £5,327.75, shows the first offer is actually cheaper despite the higher standing charge component being smaller in this case.
If your business is on a half-hourly meter, also check the capacity charge, sometimes called Available Supply Capacity or Agreed Capacity. This is a charge for the maximum demand you are entitled to draw, and many sites are set at a capacity level well above what they actually use, which means paying for headroom that is never touched.
Ask each supplier whether the quote includes pass-through costs that can change during the contract term, such as certain balancing or capacity market charges, versus a fully fixed all-in rate. Two quotes with an identical headline rate can carry very different risk if one allows mid-term cost pass-through and the other does not.
Check the renewable energy mix if it matters to your business. Standard and REGO-backed renewable tariffs are sometimes priced closely together, but not always, so ask the question directly rather than assuming green energy carries an automatic premium.
Look at the notice period and any automatic renewal or rollover clause in each proposed contract, not just your current one. A contract that rolls onto a higher rate automatically if you do not act removes the benefit of comparing sharply now, only to be re-exposed at the next renewal.
Finally, compare like for like on timing. Wholesale electricity prices move daily, so quotes gathered a week apart are not a fair comparison. Requesting all quotes within the same short window, ideally through a single comparison submission, gives the fairest picture of where the market genuinely sits for your business.
Where your business has more than one electricity meter, resist the temptation to accept the same headline rate across every site without checking consumption individually, since a rate that works well for a high-usage warehouse meter can be a poor fit for a low-usage storeroom meter on the same account, purely because the standing charge weighs so differently at different volumes.
If your premises has recently had efficiency work done, such as an LED lighting upgrade or new heating controls, request quotes using your most recent months of consumption rather than an older annual figure, since suppliers pricing against outdated, higher usage will overstate what you are likely to actually consume and can make an otherwise competitive rate look worse than it is.
Because the wholesale electricity market moves every trading day, a quote you were given last Monday is not a fair comparison against one you receive this Friday. Request every offer within the same short window, ideally through one submission, so the ranking you end up with reflects genuine differences between suppliers rather than a market that simply moved in between.
None of this matters unless you actually run the numbers on your own meter. Take your real consumption, feed it into a handful of fresh electricity quotes, and see where your current deal actually sits against the market today rather than relying on how competitive it felt when you signed it.
Distribution charges for electricity are set regionally by whichever network operator covers your postcode, and while these charges cannot be negotiated with a supplier, they are one of the reasons two businesses of identical size in different parts of the country can be quoted meaningfully different unit rates for what looks like the same product.
