- As of 2026, most small business gas unit rates sit broadly between 6p and 9p per kWh, with daily standing charges commonly ranging from around 25p to 75p depending on supplier and meter type.
- Business gas is not covered by the Ofgem domestic price cap, so there is no upper limit on what a supplier can charge a non-domestic customer.
- Fixed business gas contracts typically run for 1 to 5 years and cannot usually be exited early without a termination fee or buy-out cost.
- If a fixed contract ends without renewal or a valid switch, the supplier can move the account onto out-of-contract or "deemed" rates that are often substantially higher.
- Micro-business customers can refer an unresolved complaint to the Energy Ombudsman free of charge, usually after 8 weeks or once a deadlock letter is issued.
Business gas pricing combines a unit rate per kWh and a daily standing charge, set by contract type, usage, location, and credit. There is no cap, fixed deals avoid volatility, and unresolved disputes can go to the Energy Ombudsman.

What small businesses actually pay for gas in 2026
Business gas is priced very differently from household gas, and that difference catches a lot of small firms by surprise. A non-domestic gas account sits outside the Ofgem domestic price cap, so there is no government-set ceiling on the unit rate or the standing charge. The price you pay is whatever your supplier quotes and you agree to, which makes understanding the figures on your contract genuinely worth the effort.
As of 2026, most small and micro-business gas unit rates fall broadly between 6p and 9p per kWh once wholesale costs eased from the extreme highs seen in 2022 and 2023. Daily standing charges for business gas commonly run from around 25p to 75p, though some larger or higher-usage meters carry higher fixed daily costs. These are indicative ranges, not quotes: your actual rate depends on where you are, how much gas you burn, your meter type, your business credit profile, and crucially the day you sign, because business energy is priced live against the wholesale market.
The most important thing to grasp is that a quote is a snapshot. Two identical cafes on the same street can pay different unit rates simply because they signed their contracts on different days. That is normal in the non-domestic market and is the reason timing and contract length matter as much as the headline pence figure.
Unit rates and standing charges explained
Every business gas bill is built from two core charges. The unit rate is the price per kilowatt hour (kWh) of gas you consume, expressed in pence. It scales with usage, so a busy bakery running ovens all day pays far more in total than a small office with a single boiler, even on the same rate. The standing charge is a fixed daily cost that you pay regardless of whether you use any gas at all. It covers the cost of maintaining your connection to the gas network, meter operation, and certain administrative and network charges.
Because the standing charge is fixed, it has a proportionally larger impact on very low-usage premises. If your business uses little gas, a high standing charge can quietly dominate your bill, so it is always worth checking both numbers rather than fixating on the unit rate alone. Conversely, a high-consumption site should pay closest attention to the unit rate, because even a fraction of a penny difference per kWh multiplies across tens of thousands of units.
VAT is added on top. Most businesses pay 20% VAT on energy, but premises with very low consumption, or those where at least 60% of energy use is for a qualifying non-business purpose such as a charity or certain residential elements, may qualify for the reduced 5% rate. The Climate Change Levy (CCL) may also apply to business gas, though some small users and certain reliefs reduce or remove it.
Contract types and typical rate ranges
The contract you sign shapes both your price and your flexibility. The table below sets out the main non-domestic gas contract types alongside indicative 2026 ranges. Treat these as illustrative bands to help you sense-check a quote, not as guaranteed prices.
| Contract type | Typical unit rate range (p/kWh) | Typical standing charge (p/day) |
|---|---|---|
| Fixed term (1 year) | 6.5 - 9.0 | 28 - 70 |
| Fixed term (2-3 years) | 6.0 - 8.5 | 25 - 65 |
| Variable / flexible | Tracks wholesale, often 7.0 - 11.0 | 30 - 75 |
| Out-of-contract / deemed | Typically the highest, often 9.0 - 14.0+ | 40 - 90+ |
| Rollover (auto-renewed) | Often above market fixed rates | Varies, often elevated |
A fixed contract locks your unit rate and standing charge for the agreed term, giving budget certainty but no benefit if wholesale prices fall. A variable or flexible contract moves with the market, which can help when prices drop but exposes you to spikes. Out-of-contract and deemed rates apply when no agreed contract is in place, for example when you take over premises and have not yet signed a deal, and they are usually the most expensive tariffs a supplier offers.
What drives your business gas rate
Several factors combine to produce the number on your quote. Understanding them helps you judge whether a price is fair.
Wholesale gas prices are the single biggest driver. Suppliers buy gas on the wholesale market and pass that cost through, which is why business rates moved so dramatically through 2022 and 2023 and why the day you sign matters. Contract length influences price because longer fixed terms let a supplier spread risk, though they also lock you in. Annual consumption matters: higher-usage sites often secure keener unit rates because they are more attractive accounts. Location feeds in through regional network charges, which vary across Great Britain. Business credit profile affects pricing too, because a supplier prices in the risk of non-payment. Finally, meter type and payment method play a part, with direct debit and modern metering generally viewed more favourably than prepayment or quarterly billing.
How to read your business gas bill
A business gas bill can look dense, but the figures you need are consistent. Look for your unit rate (p/kWh) and your standing charge (p/day), usually shown near the charge breakdown. Check the billing period and whether the reading is actual or estimated, because estimated bills can over- or under-charge until corrected by a real meter reading. Find your contract end date and any renewal window, since this is the date that protects you from rolling onto worse rates. Note your MPRN (Meter Point Reference Number), the unique identifier for your gas supply that you will need if you switch or raise a query. Confirm the VAT rate applied and whether any Climate Change Levy appears. If anything looks wrong, contact your supplier in writing and keep a record, because a clear paper trail is essential if a dispute later escalates.
The automatic rollover trap
One of the most costly mistakes a small business makes with gas is doing nothing. When a fixed contract approaches its end date, suppliers must contact you, and if you do not actively renew, switch, or give notice within the contract's terms, you can be moved automatically onto a rollover or out-of-contract tariff. These rates are frequently well above the competitive fixed deals available to a new customer.
Industry rules require suppliers to set out renewal terms and end dates clearly, and micro-businesses in particular benefit from protections around contract transparency and termination. Even so, the practical defence is to diary your contract end date well in advance, watch for the renewal window stated in your terms, and serve any required termination notice in writing. Acting early, ideally several months before expiry, gives you time to compare offers and avoid being defaulted onto expensive deemed rates. If you have already rolled over and feel you were not given proper notice of the renewal terms, that is exactly the kind of issue you can raise as a formal complaint.
How to dispute a business gas issue via the Energy Ombudsman
If you have a problem with your supplier, whether a billing error, a disputed rollover, a switching failure, or poor service, there is a free route to escalate. Start by complaining to your supplier directly and in writing, keeping copies of everything. Suppliers have a complaints procedure they must follow under their licence conditions.
If the complaint is not resolved after 8 weeks, or if the supplier issues a deadlock letter sooner, eligible micro-business customers can refer the case to the Energy Ombudsman. The service is free and independent. If the Ombudsman finds in your favour it can direct the supplier to put things right, which may include corrected billing, an apology, a practical remedy, or a financial award. To qualify as a micro-business you generally need to fall under thresholds based on employee numbers and annual energy consumption or turnover, so it is worth confirming your eligibility before you refer. Keeping a tidy record of dates, readings, and correspondence makes any complaint far stronger.
Practical ways to keep your gas costs down
Beyond securing a competitive contract, small operational steps add up. Submit regular meter readings to avoid estimated billing. Review your contract end date every year so you never drift onto deemed rates. Consider the trade-off between a longer fixed term for budget certainty and a shorter term for flexibility. Check whether you qualify for the reduced 5% VAT rate or any Climate Change Levy relief. And make sure your standing charge is reasonable for your usage profile, since a low-usage site is especially exposed to high daily fixed charges.
Frequently Asked Questions
What is a good business gas rate UK?
As of 2026, a competitive small-business gas unit rate broadly sits between 6p and 9p per kWh, with a standing charge often in the 25p to 75p per day range. What counts as good depends on your usage, location, and the wholesale market on the day you sign, so compare a fresh quote against current fixed deals rather than an old bill.
How is business gas priced?
Business gas is priced as a unit rate per kWh plus a fixed daily standing charge, then VAT and any Climate Change Levy are added. The unit rate reflects wholesale gas costs, your annual consumption, contract length, location, meter type, and your business credit profile. Unlike household gas, it is not covered by the Ofgem domestic price cap.
Can I fix my business gas rate?
Yes. Fixed-term business gas contracts typically run from 1 to 5 years and lock both your unit rate and standing charge for the agreed period. This gives budget certainty against wholesale volatility, but you usually cannot exit early without a termination fee, and you will not benefit if market prices fall during the term.
What happens if I do not renew my contract?
If a fixed contract ends and you do not renew, switch, or give the required notice, your supplier can move you onto out-of-contract, deemed, or rollover rates. These are typically the most expensive tariffs available, so diarising your end date and acting within the renewal window is the simplest way to avoid overpaying.
How do I complain about my business gas supplier?
Complain to your supplier in writing first and keep records. If it is unresolved after 8 weeks, or you receive a deadlock letter sooner, eligible micro-business customers can refer the case free of charge to the Energy Ombudsman. The Ombudsman is independent and can direct the supplier to correct billing or provide a remedy.
Is business gas cheaper than domestic gas?
Not necessarily. Business gas can have lower unit rates for higher-usage accounts, but it is not protected by the domestic price cap and adds 20% VAT for most firms plus a potential Climate Change Levy. Whether it works out cheaper depends entirely on your contract terms, consumption, and the rate you secured.
