Micro business energy prices explained

A micro business, for energy regulation purposes, is generally defined as one using no more than 100,000 kWh of electricity or 293,000 kWh of gas a year, employing fewer than ten people, or having a turnover or balance sheet below roughly £2 million. This classification matters because micro businesses receive some additional protections under Ofgem's rules that do not apply to larger commercial consumers.

Micro businesses typically see the highest unit rates in the business energy market, again largely because fixed costs, standing charges and administration overheads make up a larger proportion of a small total bill, and because the relative risk premium suppliers apply can be slightly higher for the smallest accounts.

One key protection for micro businesses is around contract renewal transparency. Suppliers are required to provide clear information ahead of contract end dates, including the termination notice period, to reduce the risk of businesses being rolled onto expensive terms without adequate warning.

Micro businesses are also more likely to be affected by minimum contract terms and to be quoted on standard rate cards rather than bespoke pricing, since the administrative cost of negotiating individually is harder for suppliers to justify at very low volumes. This makes comparing across the whole market, rather than negotiating with a single incumbent supplier, particularly valuable for this segment.

Worked example: a micro business, such as a single-operator hairdressing salon, using 4,000 kWh of electricity a year at 32p per kWh, spends £1,280 on commodity plus a standing charge of 48p a day, around £175.20, totalling £1,455.20 a year. A quote of 26p per kWh with the same standing charge reduces the total to £1,215.20, a saving of £240, which is meaningful relative to a small overall energy budget.

Because absolute bills are small, some micro businesses assume comparison is not worth the effort, but the proportional saving available is often larger than for bigger businesses, precisely because standing charges and rate differentials have more relative impact at low volumes.

Deemed and out-of-contract rates hit micro businesses particularly hard, since these rates are set with no negotiation and no fixed term, and can represent a disproportionately large share of a very small business's operating costs if left in place for several months.

Micro businesses should still gather at least a few months of consumption data, or a recent bill, before requesting quotes, since even at low volumes accurate data produces sharper and more reliable pricing than an estimate.

A comparison service such as Compare Market can be especially useful for micro businesses because it removes the time burden of contacting suppliers individually, which is often the biggest practical barrier for an owner-operator running the business single-handed.

Ofgem's micro business protections also include a requirement for suppliers to offer a range of payment methods and to provide contract information in a way that is clear and not misleading, which matters in practice because the smallest businesses are the least likely to have dedicated finance staff scrutinising every clause of a supply agreement.

A single-site micro business considering a switch should not be put off by suppliers' minimum consumption thresholds for their most competitive tariffs, since many suppliers maintain a specific product range aimed squarely at micro businesses, and a comparison service can identify which suppliers are actively competing for accounts of your size rather than treating you as an afterthought.

As with other small accounts, usage bands for a micro business typically sit well under 20,000 kWh a year for electricity, and the resulting bill is dominated by fixed costs rather than the commodity element, which is precisely why comparing suppliers, even for a modest total spend, is rarely a wasted exercise.

The notice window in a micro business contract deserves the same attention it would get in a much larger company, since Ofgem's protections around renewal transparency exist specifically because the smallest accounts are the ones most likely to be caught out by a missed deadline.

A single-operator business with no dedicated admin support benefits most from simply pulling the latest bill, checking the meter reference and end date, and letting a comparison service run the market search, since that removes almost all of the manual legwork that otherwise puts owners off comparing at all.
