The business energy comparison checklist

A structured checklist takes the guesswork out of comparing business energy prices and makes sure nothing important gets missed between gathering data and signing a new contract.

First, confirm your current contract end date and termination notice window. This single detail determines your deadline for giving notice and is the most common point of failure that leads businesses onto expensive deemed rates.

Second, locate your meter identifiers, the MPAN for electricity and MPRN for gas, from a recent bill, since these are required by any supplier to produce an accurate quote.

Third, gather twelve months of consumption data in kWh if available, since this produces sharper and more reliable quotes than a single bill or an estimate, and gives you a proper baseline to judge new offers against.

Fourth, decide which contract lengths you are open to comparing, one, two or three years, and request quotes across each, since the cheapest term shifts with market conditions and is rarely the same at every renewal.

Fifth, submit your data to multiple suppliers within the same short window, either directly or through a comparison service such as Compare Market, since wholesale prices move daily and quotes gathered days apart are not a fair comparison.

Sixth, convert every quote into an estimated annual cost using your actual consumption, combining unit rate and standing charge, rather than ranking offers by unit rate alone, since a lower rate with a higher standing charge can cost more overall at low consumption levels.

Seventh, check whether each quote is fully fixed or includes pass-through clauses allowing certain non-commodity costs to change during the term, since two apparently identical fixed rates can carry different risk depending on this detail.

Eighth, review the termination notice period and any automatic renewal clause on the new contract, not just the current one, so you are not caught by the same issue again at the next renewal.

Ninth, factor in supplier reliability and billing accuracy alongside price, since a cheaper contract that generates frequent billing disputes can cost more in staff time than it saves on the rate.

Tenth, once you select a supplier, confirm the new contract's start date aligns exactly with your current contract's end date to avoid any gap that would default your account to deemed rates.

Finally, calendar the new contract's end date and notice window the same day you sign, so the next renewal starts with plenty of lead time rather than under deadline pressure. Running through this checklist at every renewal, rather than only when prices feel high, is what keeps a business consistently on competitive energy rates.

Keep a written record of who provided each quote, when it was issued, and its exact terms, since commercial energy quotes expire quickly and a verbal assurance from a supplier representative made a week ago is not something you can rely on being honoured once you come to sign, particularly if wholesale prices have moved in the meantime.

Revisit this checklist not only at contract renewal but also whenever your business changes materially, for example a significant increase or decrease in trading hours, a change of premises, or new equipment that shifts your consumption pattern, since any of these can be a good reason to re-tender even mid-way through an existing fixed term's natural planning cycle.

Before requesting quotes, confirm which category your meter falls into, since a half-hourly metered site should be prepared to share thirty-minute consumption data rather than a single annual total, and knowing this in advance saves a round trip with the supplier once the tender is already underway.

Add a line to the checklist confirming whether your business might qualify for reduced-rate VAT or a Climate Change Levy exemption, since this is easy to overlook when focused on comparing headline rates, yet it can change the effective cost of an otherwise identical quote by a meaningful margin.

Finally, sense-check the quotes you receive against the size of business you actually run, since an offer that looks unusually cheap or expensive relative to what similar-sized businesses typically report paying is worth querying with the supplier before signing, rather than assumed to be correct simply because it arrived in writing.
