Compare business gas prices

Comparing business gas means lining quotes up on the same basis. Same meter, same day, four numbers: unit rate, standing charge, contract length and exit terms. Suppliers reprice daily, so quotes gathered a week apart come from two different markets. We print our commission on every quote, 1.5p per kWh, before you sign.

For scale, the UK average is 5.17p per kWh across all non-domestic consumers, including the Climate Change Levy (DESNZ, Quarterly Energy Prices, 30 June 2026, Q1 2026 data). It is a benchmark only. Figures by size sit on business gas prices, sourced per our pricing methodology.

What to compare

Unit rate

The pence you pay per kWh. Every quote leads with it. A quote can win here and still cost more over the year.

Standing charge

A fixed daily fee you pay whether the boiler runs or not. The less gas you burn, the more it decides the outcome. Turn both numbers into pounds a year and compare the totals.

Contract length

Gas fixed terms usually run from a year to several. A longer term buys price certainty and costs you flexibility, so it is a call about risk. More in our guide on whether to fix.

Exit terms

What happens if you leave early, move premises or close the site. No standard charge exists, and some are calculated on the wholesale gas left in your contract. Get yours in writing first.

How gas comparison actually works

Most comparison sites and brokers quote a panel of suppliers rather than the whole market. Ofgem is blunt about it: "Some TPIs research the whole market but others represent one or a small group of suppliers" (Ofgem, Third Party Intermediaries guidance, 14 October 2022, checked August 2026). Ask for the list.

Commission is where gas comparison gets quiet. For contracts signed on or after 1 October 2024, Ofgem requires suppliers to disclose broker fees to every non-domestic customer, as a cost per unit or a cost per day where the fee sits in the standing charge (Ofgem, Non-Domestic Market Review decision, 5 April 2024). It reaches you through the contract's Principal Terms and on request, and is not required on the bill, which is why most businesses never see it. Under 293,000 kWh of gas a year you also count as a micro business, and get the figure as a lump sum for the whole contract (Ofgem, Third Party Intermediaries guidance, 14 October 2022).

Two limits worth knowing. Ofgem caps nothing, so a disclosed commission can still be large, and fees a broker bills you directly sit outside the rule altogether. The full mechanics are in how energy brokers get paid.

Comparing yourself or using a broker

You can run this yourself. For a single meter it is a decent afternoon: ring suppliers direct, give each the same annual consumption from your bill, and ask for a unit rate and standing charge on one contract length. Quotes usually expire the same day, so gather them together. Some suppliers price small gas sites only through intermediaries.

A broker runs that pass for you and is paid by the supplier that wins. Ofgem suggests two questions: which suppliers will they approach, and will you be charged directly or indirectly? Our answers are the gas suppliers directory, and indirectly, at 1.5p per kWh on every contract length, shown on the quote. What happens next is in how to switch business energy.

Sometimes the right answer is to stay put. Mid-contract on a rate agreed in a calmer week, today's market may have nothing better, and an exit charge to find out is a bad trade. Ending there is a result, and we say so in writing.
