What are business gas rates in the UK?

Business gas is priced on two parts: a unit rate (the price per kWh you use) and a standing charge (a fixed daily fee to keep your supply connected). In 2026, typical rates are:

Small business: around 8p to 9p per kWh

Medium business: around 7p to 8p per kWh

Large business: around 6.5p per kWh on daily-metered contracts

Unlike the domestic market, there is no price cap on commercial gas, so variable rates can rise sharply with the wholesale market. Fixing your rate gives you certainty. To get a rate for your business, compare quotes here.

How much does business gas cost per kWh?

Most UK businesses pay between 6.5p and 9p per kWh in 2026, with larger users at the lower end. A low unit rate is not always the cheapest deal: a headline-low unit rate paired with a high standing charge can cost more over the year than a slightly higher unit rate with a low standing charge. We compare both parts across suppliers so you see the true annual cost, not just the sticker price.

What is a standing charge on business gas?

The standing charge is a fixed daily fee you pay regardless of how much gas you use. In 2026 it typically runs 25p to 45p per day for small and medium businesses, and higher for large sites. If your usage is low, the standing charge makes up a bigger share of your bill, which is where our 0p standing charge tariffs can save you the most.

Business gas contract types explained

Fixed-rate: Your unit rate is locked for the contract term, typically 1 to 5 years. Protects you from price rises; you will not benefit if the market falls.

Variable-rate: Your rate moves with the wholesale market. With no commercial price cap, this can climb quickly.

Deemed / out-of-contract: The default, most expensive rates you are placed on if a contract lapses or you move into new premises. Worth switching off as soon as possible.

Green tariffs: Suppliers offering lower-carbon and green gas options. We work with these suppliers so your switch supports lower-carbon energy from day one.

Business electricity FAQs

How much is business gas per kWh in 2026?

Most UK businesses pay 6.5p to 9p per kWh, with larger, daily-metered users at the lower end. There is no price cap on commercial gas, so variable rates can run higher than fixed deals. We can benchmark your current rate and find better options.

What is the VAT rate on business gas?

The standard rate is 20%. If your business is a low energy user (under 5,000 kWh of gas a year) or qualifies as charity or non-business use, you may pay a reduced 5% rate and be exempt from the Climate Change Levy. Ask our consultants to check your eligibility.

Does gas count as a business expense?

Yes. If the gas is used solely for business operations, such as heating your premises or powering processes, it is usually an allowable expense against your taxable profits. Keep your bills and payment records to support any claim.

Can I cancel my business gas contract early?

Sometimes, but early-termination fees may apply depending on your terms. Check your contract, or ask us to review your options.

How can my business reduce gas emissions?

Switch to a renewable or lower-carbon gas tariff, improve insulation and heating efficiency, maintain gas equipment, monitor usage with smart meters, and consider carbon offsetting. Lower emissions cut costs and support your sustainability goals.
