What does business energy cost in 2026?
Business energy costs in 2026 vary widely by contract, usage, and location. There is no single price, as non-domestic contracts are not subject to the domestic price cap. The typical consumption values for domestic customers were reset to 2,500 kWh electricity and 9,500 kWh gas in July 2026, but business rates differ.
For a microbusiness, defined as having fewer than 10 employees and under 100,000 kWh electricity or 293,000 kWh gas per year, suppliers must follow specific rules. These include clear contract terms and notice periods. However, prices are still market-driven.
To estimate costs, businesses should review their annual usage in kWh and compare quotes from multiple suppliers. Standing charges and unit rates vary. The 100,000 kWh threshold is a key figure for determining microbusiness status, which affects protections.
Businesses should check their contract renewal date and start comparing at least 3 months before. Using a comparison service can help, but always verify the total cost including VAT and any additional fees.
Why are small businesses charged more per unit?
Small businesses often pay higher unit rates than larger ones because suppliers spread fixed costs over fewer units. The microbusiness threshold of 100,000 kWh electricity or 293,000 kWh gas per year is used by Ofgem to define smaller businesses, but it does not guarantee lower prices.
Suppliers may charge higher rates to cover administrative and metering costs. Additionally, small businesses have less negotiating power. However, the 100,000 kWh figure is a reference point for regulatory protections, not a price benchmark.
To mitigate higher rates, small businesses can consider collective switching or joining a buying group. Comparing quotes regularly is essential. The 100,000 kWh threshold also affects VAT: below 33 kWh electricity or 145 kWh gas per day, a reduced 5% VAT rate applies, which can lower bills.
Businesses should check their daily consumption to see if they qualify for the reduced VAT rate. This can be a significant saving for very small users.
| Rule | Detail | Source |
|---|---|---|
| Domestic price cap | does not apply to non-domestic contracts | Ofgem |
| Microbusiness test | fewer than 10 employees and under 2 million euros turnover, or under 100,000 kWh electricity or 293,000 kWh gas a year | Ofgem |
| VAT | 20% standard; 5% reduced rate below 33 kWh electricity or 145 kWh gas a day | HMRC |

How are business energy prices structured?
Business energy prices are structured with two main components: unit rates (pence per kWh) and standing charges (daily pence). Unit rates cover the energy itself, while standing charges cover supply costs. Unlike domestic tariffs, there is no price cap for non-domestic contracts.
Contracts can be fixed or flexible. Fixed contracts lock in a unit rate for a set period, typically 1 to 5 years. Flexible contracts allow purchasing energy in tranches, which can be beneficial for larger users. The 100,000 kWh threshold is relevant for microbusiness protections, but pricing is still market-based.
VAT is applied at 20% standard, but a reduced 5% rate applies if consumption is below 33 kWh electricity or 145 kWh gas per day. This is a key factor for small businesses to check.
Businesses should review their bill to understand the breakdown. Comparing total costs, not just unit rates, is crucial because standing charges vary.
What contract types are available to UK businesses?
UK businesses can choose from several contract types: fixed, variable, and flexible. Fixed contracts offer price certainty for a set term, often 1 to 5 years. Variable contracts have rates that can change, but they may offer more flexibility. Flexible contracts are for larger users, allowing energy to be bought in blocks.
For microbusinesses (under 100,000 kWh electricity or 293,000 kWh gas per year), suppliers must provide clear contract terms and cannot roll over contracts without notice. This is a protection under Ofgem rules.
When choosing a contract, consider the length, exit fees, and renewal terms. The 100,000 kWh threshold is a guide for microbusiness status, but not all suppliers use it consistently.
Businesses should compare quotes from multiple suppliers and read the terms carefully. A broker can help, but be aware of commission costs.
What is the TPI market and what should businesses know?
Third-party intermediaries (TPIs) are brokers or consultants who help businesses find energy deals. They can be useful for comparing offers, but they may earn commissions from suppliers, which can affect the price you pay.
Businesses should ask TPIs about their fees and whether they are independent. The 100,000 kWh threshold is relevant because TPIs often target microbusinesses, but the same protections apply.
When using a TPI, ensure they are accredited by a recognised body, such as the Utilities Intermediaries Association (UIA). Always check the contract terms and the total cost, including any broker fees.
It is advisable to get quotes directly from suppliers as well, to compare. The 100,000 kWh figure is a benchmark for microbusiness status, but TPIs may not always disclose their commission.
How to compare business energy effectively
To compare business energy, gather your annual usage in kWh and your current contract details. Use comparison websites or contact suppliers directly. Focus on the total annual cost, including unit rates, standing charges, and VAT.
For microbusinesses (under 100,000 kWh electricity or 293,000 kWh gas per year), ensure you are not being overcharged. The 100,000 kWh threshold is a key figure for eligibility for certain protections.
When comparing, check the contract length, exit fees, and renewal terms. Also, verify if the reduced VAT rate of 5% applies if your daily consumption is below 33 kWh electricity or 145 kWh gas.

What has happened to business energy prices since 2021?
Since 2021, business energy prices have been volatile due to global market changes. The domestic price cap was introduced in January 2019, but it does not apply to non-domestic contracts. In October 2022, the cap moved to quarterly reviews, but again only for domestic customers.
For businesses, prices have fluctuated with wholesale markets. The 100,000 kWh threshold for microbusinesses has remained a constant reference point for regulatory protections, but it does not cap prices.
In 2026, the typical domestic consumption values were reset to 2,500 kWh electricity and 9,500 kWh gas in July, and the Q4 cap was announced at £1,723 on 26 August 2026. These figures are for domestic customers, not businesses.
Businesses should monitor market trends and consider fixed contracts to manage risk. The 100,000 kWh figure is not a price indicator.
How can businesses reduce energy costs in practice?
Businesses can reduce energy costs by improving efficiency, such as upgrading lighting to LED, installing smart meters, and optimising heating and cooling. Behavioural changes, like turning off equipment when not in use, also help.
Reviewing your contract and comparing quotes is essential. The 100,000 kWh threshold is a key figure for microbusiness status, which may offer some protections, but savings come from shopping around.
Consider renewable energy options or on-site generation, but these require capital investment. Also, check if you qualify for the reduced VAT rate of 5% if your daily consumption is below 33 kWh electricity or 145 kWh gas.

What are the rules for microbusiness energy contracts?
Ofgem defines a microbusiness as having fewer than 10 employees and under 2 million euros turnover, or under 100,000 kWh electricity or 293,000 kWh gas per year. These businesses have specific protections, such as clear contract terms and a 30-day notice period for renewals.
Suppliers must not roll over contracts without consent, and they must provide a summary of key terms. The 100,000 kWh threshold is a critical figure for determining eligibility.
If a microbusiness has a complaint, they can contact the Energy Ombudsman after 8 weeks or receiving a deadlock letter. This is a free service.
Businesses should keep records of their consumption to confirm their status. The 100,000 kWh figure is a benchmark, but actual usage may vary.
How does VAT affect business energy bills?
VAT on business energy is generally 20% standard. However, a reduced rate of 5% applies if your daily consumption is below 33 kWh electricity or 145 kWh gas. This is based on the site's usage, not the business size.
To qualify, you must use less than these thresholds per day on average. The 100,000 kWh annual figure is not directly related to VAT, but it can help estimate daily usage.
Businesses should check their bills to ensure the correct VAT rate is applied. If not, they can contact HMRC.

Frequently asked questions
What is the average business energy bill in 2026?
There is no single average for business energy bills in 2026 because prices vary by usage, location, and contract. Unlike domestic customers, businesses are not protected by a price cap. For context, the domestic price cap for Q4 2026 was announced at £1,723, but this does not apply to businesses. To estimate your bill, multiply your annual kWh usage by your unit rate and add standing charges.
Does the energy price cap apply to businesses?
No, the energy price cap does not apply to non-domestic contracts. It only applies to domestic customers on standard variable tariffs. Businesses are free to negotiate their own contracts, and prices are market-driven. However, microbusinesses (under 100,000 kWh electricity or 293,000 kWh gas per year) have specific protections, such as clear contract terms and notice periods.
What is the 100,000 kWh threshold for business energy?
The 100,000 kWh threshold is used by Ofgem to define a microbusiness for electricity consumption. If your business uses less than 100,000 kWh of electricity per year, and also meets other criteria (fewer than 10 employees and under 2 million euros turnover), you are considered a microbusiness. This status gives you certain protections, such as no automatic rollover of contracts.
How can I reduce the business energy bills?
To reduce business energy bills, start by comparing quotes from multiple suppliers to ensure you are on the best deal. Consider improving energy efficiency, such as installing LED lighting, using smart meters, and adjusting heating schedules. Also, check if you qualify for the reduced 5% VAT rate if your daily consumption is below 33 kWh electricity or 145 kWh gas. Reviewing your contract terms and avoiding automatic renewals can also help.
What is the difference between a fixed and variable business energy contract?
A fixed business energy contract locks in a unit rate for a set period, typically 1 to 5 years, providing price certainty. A variable contract has rates that can change with the market, offering flexibility but less predictability. Fixed contracts may have exit fees, while variable contracts often allow you to leave with notice. The choice depends on your risk tolerance and market conditions.
Are there any grants or schemes to help businesses with energy costs?
There are various government schemes and grants available, but they change frequently. As of 2026, specific schemes may be available, but it is best to check the latest government guidance. Businesses can also consider energy efficiency loans or incentives for renewable energy installations. The 100,000 kWh threshold does not directly affect eligibility for grants, but it may determine your business size category.
