What UK businesses pay for gas

Between April and June 2026, UK businesses paid an average of 5.28p per kWh for gas, including the Climate Change Levy but not VAT. The smallest users paid more, at 9.31p. These figures come from the government and were published on 29 September 2026.

These prices cover the whole bill apart from VAT, so standing charges are spread across every kWh. The very small band covers sites using up to 278,000 kWh a year. To compare your own price, add up a year of bills before VAT, divide the total by the kWh they cover and multiply by 100 to get a figure in pence.

What affects the gas prices you're offered

Business gas prices aren't set from a public price list. Instead, each supplier prices your site based on a few things it knows about you:

• Your annual quantity (AQ). This is the industry's estimate of how much gas your meter uses in a year in normal weather. Suppliers base your contract price on it, and it also helps set your transport charges.
• How much you use. If you use less, the fixed costs are spread over fewer kWh, so smaller users pay more per kWh, as the table above shows.
• When you're quoted. Suppliers base each quote on wholesale prices at the time, so it's usually only valid for a short while.
• Where you are. The cost of carrying gas to your site varies from region to region.
• The contract you choose. That means how long it runs, and whether all your costs are fixed or some are passed through as they change.
• Your business's credit record. Suppliers usually run a credit check, and depending on the result they may ask for a deposit or offer different terms.
• Being out of contract. Deemed and out-of-contract rates are usually much higher than a new fixed contract. Find your supplier's deemed rates.

Keep your annual quantity up to date

Your AQ is recalculated each month, but only when a new meter reading reaches the industry's systems. If nobody has read your meter for a while, your AQ can be a long way off what you use now, and your quotes can be too.

• Give your supplier regular meter readings, especially if your use has changed.
• Compare the AQ on your bill or quote with a year of your own readings.
• If it looks wrong, ask your supplier or broker to put it right before you agree a contract.

Types of business gas contract

The type of contract decides whether your prices can change during the term, so check which kind a quote is for before you compare them.

Gas and electricity are usually separate contracts, so they can be with different suppliers and end on different dates. It's worth keeping both end dates in your diary.

How to compare business gas quotes

A low unit rate can hide a high standing charge, so start by comparing what each quote costs over a year, then look at the terms.

1. Find your yearly use in kWh and your supply number (MPRN), which are both on your bill.
2. Check the annual quantity each supplier has used. If it's different from your own figure, ask why before you compare quotes.
3. Work out each quote's yearly cost, using the same yearly use for every quote.
4. Check whether it's fully fixed, or whether transport and other costs can be passed through during the term.
5. Check the length and end date, and what happens when it ends, whether that's a rollover, a rolling contract or out-of-contract rates.
6. Check the exit terms, meaning the notice you'll need to give and any fee for leaving early. Business contracts don't usually come with a cooling-off period.
7. Check the broker fee if a broker arranges the contract. Suppliers have to show it in the contract's main terms.
8. Compare quotes from the same few days, because prices move with the market.

The Climate Change Levy and VAT are added on top at the same rates whichever quote you choose, so they don't change how the quotes compare.

Small business gas prices

Smaller businesses usually pay more per kWh for gas, partly because fixed costs, such as standing charges, are spread over fewer units. In April to June 2026, businesses in the very small band, using up to 278,000 kWh a year, paid an average of 9.31p per kWh, against 5.28p for all businesses.

Two things to check if your site is small:

• 5% VAT on low use. If your site uses no more than 145 kWh of gas a day on average, your gas is charged VAT at 5% rather than 20%.
• Microbusiness protections. You count as a microbusiness if you have fewer than 10 employees and a turnover or balance sheet of no more than £2 million, or if you use up to 293,000 kWh of gas or 100,000 kWh of electricity a year. Your supplier must then tell you your renewal prices before your contract ends, and the notice on an evergreen contract, one that rolls on until you end it, can't be longer than 30 days.

Getting business gas quotes

When you ask for quotes, have these to hand:

• your MPRN, the supply number on your gas bill;
• your annual quantity (AQ), and a year of your own meter readings to check it against;
• your contract end date and any notice your contract needs;
• your business's legal name and address, and its company number if it's a limited company.

Compare quotes from the same few days, since prices move with the market, and check that every supplier has used the same annual quantity.

Choosing a business gas supplier

Your supplier is the company that bills you. The gas reaches your site through the same pipes whoever you choose, so switching doesn't change your supply. Suppliers differ on price, on contract terms such as length and exit fees, and on what they charge if a contract ends without a new one. Find your supplier's deemed rates to see what yours charges.
