20 best business energy suppliers comparison

Finding the best business energy suppliers is about more than chasing the lowest unit rate. The right supplier for your business depends on your annual kWh usage, whether you need business electricity suppliers, business gas suppliers or both, your meter type, your credit profile, your contract length, and how important renewable energy, online tools, and multi-site support are to your operation. Business contracts are priced differently from domestic tariffs, and the domestic energy price cap does not apply to standard non-domestic contracts.

Our guide compares leading UK business energy suppliers for small firms, growing SMEs and larger commercial users. It also covers the cheapest business energy suppliers, small business energy suppliers, renewable business energy suppliers, multi-site and half-hourly suppliers, no standing charge business energy, and the difference between fixed, variable, deemed and out-of-contract pricing.

Compare UK business energy suppliers

The best commercial energy suppliers are not always the same as the cheapest business energy suppliers. A small office may care most about low standing charges and easy billing, while a restaurant or hotel may care more about business gas pricing, and a multi-site operator may need half-hourly data, flexible purchasing and consolidated billing. Ofgem notes that business energy costs can include wholesale costs, network charges, VAT, Climate Change Levy, government schemes, brokerage, excess-capacity charges and other supplier costs, so the cheapest-looking quote is not always the lowest total cost.

The comparison below is designed to help businesses shortlist the most relevant suppliers by contract style, business fit and pricing approach.

• Review: See our EON business energy prices review.

SSE Energy Solutions

SSE Energy Solutions is better suited to larger organisations, more complex sites and businesses that need a more tailored commercial energy arrangement. It is a stronger name for firms with significant consumption or operational complexity than for very small businesses seeking the cheapest simple contract.

Scottish Power is another major supplier brand that businesses may compare when looking for established-scale supply and renewable generation credentials. It is usually a better fit for firms that prefer dealing with a large national provider rather than a smaller specialist supplier.

• Features: Businesses can access green energy options through fixed-term contracts. Scottish Power is involved in generating renewable energy, particularly from its UK-based wind farms.

Crown Gas & Power is particularly relevant where business gas costs are a major concern. Businesses with gas-heavy operations often compare it alongside broader commercial energy suppliers because specialist strength in gas can matter more than having the biggest national brand.

• Pricing: Crown Gas & Power specialises in providing competitive gas pricing to businesses, with contracts tailored to suit various sizes and types of organisations. They are particularly noted for offering lower-cost gas contracts for SMEs.
• Features: The company focuses on gas supply, with flexible contracts and an emphasis on efficient customer service. Crown Gas & Power also offers metering services and works closely with businesses to ensure smooth operations.

• Review: Good Energy business prices review.

Ecotricity

Ecotricity is another green-focused supplier that businesses often compare when environmental positioning matters. It is likely to appeal most to organisations that want a recognisable renewable brand and are comfortable prioritising green credentials over being solely focused on the lowest headline quote.

• Pricing: Ecotricity’s pricing is generally higher compared to other business energy suppliers due to its strong focus on green energy. However, for businesses that prioritise environmental impact, the extra cost is often seen as worthwhile.
• Features: Ecotricity offers 100% green electricity and carbon-neutral gas. As one of the first green energy suppliers in the UK, the company is committed to using energy generated from its own wind and solar parks, making it a top choice for businesses seeking to minimise their carbon footprints.

• Review: Ecotricity business prices review.

United Gas & Power

United Gas & Power is often compared by SMEs that want a supplier known for business-market focus rather than household energy. It is a relevant option for firms wanting a smaller-feel supplier while still comparing business electricity suppliers and business gas suppliers on a competitive basis.

ENGIE UK is part of the broader international ENGIE Group, a multinational energy firm with operations in generation, supply and services. This means ENGIE can cater to everything from a small office to a large industrial facility.

• Pricing: ENGIE offers tailored business electricity and gas contracts, with both fixed and flexible options depending on a company’s usage, risk appetite and sustainability goals. Its positioning is aimed at giving businesses competitive prices while also allowing more customised contract structures than a one-size-fits-all tariff.
• Features: ENGIE supplies both business electricity and gas, with options for fixed contracts, flexible purchasing, real-time market access for some customers, and quotes tailored to operational needs. It also provides online account tools for invoices, payments, meter readings and contract documents, alongside wider support around energy management and net zero goals.
• Customer Service: ENGIE presents itself as a strategic energy partner rather than just a supplier, with expert guidance and dedicated account manager support for some business customers. It also provides direct customer service and complaints channels, which helps businesses manage contracts, renewals and day-to-day account issues more easily.
• Green Energy: ENGIE has a stronger green energy focus than SEFE, offering 100% renewable electricity backed by REGO certificates as well as green gas options for businesses pursuing net zero goals. It also highlights its own renewable generation and wider low-carbon infrastructure, making it a good fit for businesses that want sustainability credentials alongside energy supply.
• Review: Engie business energy prices review.

Utilita is often more relevant to smaller organisations than to large industrial users. Businesses comparing small business energy suppliers may include Utilita when they want a straightforward option with simpler account management and a brand associated with practical energy control.

• Review: Utilita business prices review.

Ruby Energy

Ruby Energy is primarily a smaller-business option. It is likely to appeal to firms that want a compact shortlist of small business energy suppliers rather than a supplier designed mainly for large corporates and complex procurement structures.

• Pricing: Ruby Energy focuses on providing competitive pricing to small and medium businesses, particularly those looking for flexible energy contracts. They are emerging as a strong competitor in the SME energy sector.
• Features: The company emphasises renewable energy, offering 100% renewable electricity plans and smart meters to help businesses monitor and reduce their energy consumption.
• Customer Service: Ruby Energy is gaining a reputation for responsive and personalised customer service, catering to the needs of SMEs. Although still growing, it has earned positive early reviews for its transparency and customer support.
• Green Energy: Ruby Energy offers 100% renewable electricity as part of its commitment to sustainable energy solutions for businesses.
• Review: Ruby Energy business prices review.

Utility Warehouse

Utility Warehouse stands out from many other business energy suppliers because it is often considered as part of a broader bundled-services decision. That makes it more relevant to businesses that want administrative simplicity and may value combining utilities rather than sourcing each service separately.

• Pricing: Utility Warehouse offers bundled deals that combine energy, broadband, mobile, and insurance, allowing businesses to save by consolidating their utilities. Pricing for energy is competitive, especially for businesses looking to reduce costs across multiple services.
• Features: As a multi-service provider, Utility Warehouse is unique in the market. Businesses can access discounts by bundling their energy with other services. The company also offers straightforward energy tariffs and user-friendly account management tools.

• Review: UW business prices review.

Drax

Drax is a more natural fit for large commercial users than for the average small firm. Businesses with high usage, net zero targets or more advanced reporting requirements may find it more relevant than businesses simply searching for the cheapest business energy suppliers for a single low-usage site.

• Pricing: Drax Energy (formerly Haven Power) focuses on providing tailored pricing for large businesses, particularly those with high energy consumption. It offers bespoke energy solutions that help enterprises optimise their energy usage and manage their carbon footprints.
• Features: Drax is known for its renewable energy solutions and net-zero consultancy services, providing businesses with energy efficiency tools and advice on reducing emissions. It also offers detailed reporting on energy usage and savings.

• Review: Drax Energy business prices review.

Avanti Gas

AvantiGas is not a typical mains gas supplier. Instead, it specialises in LPG (liquefied petroleum gas) and energy solutions for businesses that are off-grid or not connected to the national gas network. This means AvantiGas serves sectors such as agriculture, hospitality, manufacturing and rural enterprises — essentially any business that uses LPG for heating, industrial processes, hot water or specialised equipment.

• Pricing: AvantiGas focuses on LPG rather than mains electricity or natural gas, so it is mainly relevant for off-grid businesses. Its pricing is quote-led and tailored to factors such as fuel volume, tank type, site layout and delivery requirements, with the company positioning LPG as a cost-effective option for businesses that need heating, cooking or process fuel away from the gas grid.
• Features: AvantiGas provides business LPG through bulk tank installations, bottled gas and sector-specific supply options, including solutions for commercial sites, industrial users and forklift fleets. It also offers online account management tools that let customers pay bills, place orders, view invoices, track usage and submit gauge or meter readings.
• Customer Eervice: AvantiGas puts a lot of emphasis on support and practical account management, with a customer experience team available by phone, online help resources, and digital account tools for ordering, billing and account monitoring. Its messaging is centred on reliable delivery, straightforward support and helping customers find a supply arrangement that suits their site and usage needs.
• Green Energy: AvantiGas has a clearer green fuel proposition than a traditional LPG-only supplier because it also offers BioLPG, described as a renewable liquid gas made from renewable sources, waste and recycled carbon. That makes it a suitable option for businesses that want an off-grid fuel with lower-carbon credentials while still using LPG infrastructure.
• Review: AvantiGas business prices review.

Corona Energy

Corona is an independent UK business energy supplier specialising in commercial gas and electricity. They serve a substantial number of industrial and commercial customers.

• Pricing: Corona Energy supplies business gas and electricity, with pricing built around tailored quotes rather than simple standard tariffs. Its offer includes both fixed and flexible contracts, and it is particularly geared towards organisations that want contract structures matched to their usage profile, portfolio complexity and purchasing preferences.
• Features: Corona Energy provides business gas and electricity supply for small businesses, corporates and public sector organisations. Its features include fixed and flexible contracts, renewable product options, online account management through myCorona, meter reading submission, usage tracking, billing history access and support for larger multi-site portfolios.
• Customer service: Corona Energy places a strong emphasis on account management and service support, especially for larger or more complex customers. It highlights dedicated account management for corporate and public sector clients, while its small business messaging focuses on accurate billing, smooth onboarding, 24/7 portal access and responses to queries within 48 hours.
• Green energy: Corona Energy has a stronger green energy proposition than a standard business supplier, with renewable electricity and renewable gas options available. Its site states that it can provide 100% renewable gas and electricity, including biogas from UK renewable generators, which makes it suitable for businesses that want to strengthen their sustainability credentials alongside securing commercial energy supply.
• Review: Corona Energy business prices review.

If you take the time to read through our individual supplier review pages, you’ll find very different pricing styles across the market. Octopus is highly quote-led but currently references 12, 24 and 36-month contracts, a no standing charge trial and export tariffs. Yü Energy, SEFE Energy, Engie, UGP, Ruby, Utilita and Utility Warehouse all publish more numerical pricing examples, while SSE and larger commercial suppliers lean more towards tailored contracts for bigger or more complex users.

Typical business energy prices and charges in April 2026

Business energy prices move constantly, but our current comparison data gives a useful benchmark. On our current business electricity comparison page, many mainstream PC 01–04 examples sit around 29.8p to 36.5p per kWh, with 65p to 115p per day standing charges for many listed suppliers in that smaller non-half-hourly profile range. For PC 05–08 examples, many listed rates sit around 28.5p to 34.0p per kWh, with standing charges commonly much higher at roughly 140p to 260p per day, and some premium, green or higher-risk entries materially above that.

On our current business gas comparison page, example PC 01–04 gas rates for large-brand suppliers sit around 7.5p to 8.2p per kWh with 95p to 110p per day standing charges. At the same time, supplier-specific pages show more competitive commercial gas examples in the 4p to 7p per kWh range for suppliers such as SEFE and Yü, while Engie’s published business gas examples sit around 5.1p to 6.2p per kWh.

These ranges show why businesses should compare whole-contract cost rather than just one headline number. The standing charge alone can vary substantially, and Ofgem says business bills can also include charges for balancing, distribution, transmission, meter operation, brokerage, bad debt, excess capacity and policy costs.

Indicative supplier pricing signals

The figures below are useful pricing signals from our current supplier reviews and comparison pages, rather than a promise of what every business will pay. Actual quotes still depend on postcode, meter type, annual usage, start date, contract length and credit status.

Supplier	Indicative pricing signal	Contract signal	Best fit
Octopus Energy	Fixed electricity examples around 18p to 22p per kWh, standing charges around 25p to 33p per day, plus a 0p standing charge trial for some businesses	12, 24 and 36 months	Tech-led SMEs, EV, solar and export users
Yü Energy	Electricity around 16p to 19p or 16p to 20p per kWh, gas around 4.5p to 6p, standing charges around 30p to 40p per day for small firms	12 to 36 months	SMEs comparing value and simplicity
SSE Energy Solutions	Electricity around 18p to 27p per kWh, standing charges around 25p to 50p per day; multi-site examples can fall lower	Tailored, multi-site friendly	Larger and more complex businesses
SEFE Energy	Gas around 4p to 7p per kWh; electricity standing charges around 30p to 80p per day	Commercial supply focus	Gas-heavy users
Engie	Small-business electricity from around 16.4p per kWh; gas around 5.1p to 6.2p; renewable premium around 0.3p to 0.5p per kWh	12 to 60 months	Industrial, multi-site and higher-usage firms
United Gas & Power	Electricity around 24.3p to 25.5p per kWh, gas around 7.6p to 8.2p, standing charges around 43.5p to 45p per day	12, 24 and 36 months	SMEs wanting a business-only supplier
Ruby Energy	Multi-site users over 100,000 kWh can see electricity as low as 14p per kWh and standing charges from 18p per day	Bespoke	Multi-site SMEs
Utility Warehouse	Electricity around 30p to 35p per kWh, gas around 9p to 12p, standing charges around 50p to 75p per day	Fixed, variable and green examples	Very small firms wanting bundled utilities
Utilita	Published variable and deemed electricity often around 29.9p to 33.2p per kWh with 115p to 150p per day standing charge; half-hourly deemed examples at £14.40 per day plus kVA	Published variable, deemed and out-of-contract schedules	Businesses wanting a published-rate reference point

Cheapest business energy suppliers

There is no single supplier that is always the cheapest business energy supplier. The cheapest business energy suppliers for a low-usage office may be different from the cheapest commercial energy suppliers for a restaurant, bakery, factory or care home. The biggest variables are annual usage, region, meter type, fuel mix, contract length, payment method, broker costs, network charges and the timing of the quote.

For that reason, comparing only the pence-per-kWh headline is a mistake. Businesses should compare unit rate, standing charge, contract term, pass-through charges, green premium, renewal terms, notice requirements and any advance-payment or security-deposit rules before deciding which supplier is really cheapest overall.

Small business energy suppliers

Small business energy suppliers need to work well for firms with limited admin time, tighter cash flow and lower annual usage. For many SMEs, the most important features are clear billing, competitive fixed rates, manageable standing charges, online account access, and the ability to avoid expensive rollover, deemed or out-of-contract pricing.

Ofgem defines a microbusiness as one with fewer than 10 employees and turnover or balance sheet of no more than £2 million, or one using no more than 100,000 kWh of electricity or 293,000 kWh of gas a year. It also defines a newer Small Business category as fewer than 50 employees and turnover of at most £6.5 million or balance sheet total of not more than £5 million, or one using no more than 200,000 kWh of electricity or 500,000 kWh of gas a year.

For small business energy suppliers, the most useful shortlist often includes Octopus Energy, British Gas, EDF Energy, E.ON Next, Yü Energy, United Gas & Power, Utilita, Ruby Energy and Utility Warehouse. The best fit depends on whether you want the strongest digital experience, the broadest brand familiarity, the most transparent published schedules, or the lowest quote for a straightforward single site.

Business electricity suppliers

When comparing business electricity suppliers, the biggest cost drivers are not just your import unit rate. Electricity pricing can also be shaped by non-half-hourly or half-hourly metering, profile class, distribution area, demand pattern, renewable tariff structure, meter operator charges and whether your contract includes pass-through network costs.

Businesses that want renewable business electricity should also understand REGOs. Ofgem says the Renewable Energy Guarantees of Origin scheme provides transparency about the proportion of electricity suppliers source from renewable generation, and that one REGO certificate is issued per megawatt hour of eligible renewable output. That makes REGOs relevant when comparing green business electricity suppliers and renewable business energy suppliers.

For electricity-led businesses, strong comparison options include Octopus Energy, EDF Energy, E.ON Next, Good Energy, Ecotricity and SSE Energy Solutions, with Yü Energy, UGP and Utilita also worth comparing depending on business size and contract style.

Business gas suppliers

Business gas suppliers are especially important for heat-heavy premises such as restaurants, hotels, bakeries, food manufacturers, factories, breweries, laundrettes, care homes and workshops. In those sectors, a lower gas rate can matter more to total annual cost than a small electricity saving.

If gas is the biggest part of your bill, it makes sense to compare general dual-fuel brands with more gas-relevant suppliers such as Crown Gas & Power, SEFE Energy, Engie, UGP, Yü Energy, Corona Energy and Avanti Gas where appropriate. The right shortlist for a gas-heavy business can look very different from the shortlist for an office-led electricity user.

Renewable business energy suppliers

Renewable business energy suppliers are no longer a niche choice. Many UK businesses now want green electricity to support carbon reporting, procurement policies, tenant expectations, investor communications or brand positioning. At the same time, the cost premium for green supply is not always large. Engie’s current examples suggest renewable electricity can sometimes add only around 0.3p to 0.5p per kWh, or roughly £60 to £100 a year on a 20,000 kWh example business.

If green supply matters, compare Octopus Energy, Good Energy, Ecotricity, EDF Energy, E.ON Next and Drax, and then check exactly how the renewable claim is framed. Some suppliers lead with a green brand identity, while others offer renewable-backed contracts within a broader commercial supply portfolio.

Multi-site and half-hourly business energy suppliers

Multi-site businesses usually need more than a simple fixed tariff. They often need consolidated billing, centralised reporting, stronger account management, half-hourly data, clearer procurement support and the ability to manage different supply start and end dates across a property portfolio. Ofgem notes that business bill detail will vary by business size, contract type and meter type, including half-hourly and smart meters.

SSE Energy Solutions, Drax, TotalEnergies, British Gas, EDF Energy, Engie and Octopus are more relevant to this type of business than suppliers focused mainly on small single-site accounts. Octopus says it can support portfolios from 4 accounts and 100 MWh upwards, while Ruby says multi-site businesses consuming over 100,000 kWh annually can see electricity rates as low as 14p per kWh and standing charges from 18p per day depending on profile.

No standing charge business energy

One of the strongest long-tail search terms in the market is business energy with no standing charge. For most suppliers, standing charges still apply, and Ofgem says the standing charge covers costs such as moving energy through cables and pipes, supplier business costs and some government social and environmental schemes.

However, Octopus has launched a No Standing Charge Tariff for some business customers. Its current public guidance says the tariff has a 0p per day standing charge, is on a fixed 12-month contract, is aimed at certain electricity bands, and does not require a smart meter. That will not suit every business, but it is relevant for searchers specifically looking for no standing charge business electricity.

Deemed and out-of-contract business energy rates

Deemed and out-of-contract rates are among the most important topics businesses overlook. Ofgem says that if a supplier fails, the new supplier will place the business on a special deemed contract, which is a contract the business has not chosen. Ofgem also says these deemed contracts can be more expensive because the supplier is taking on more risk.

Published supplier schedules show how big the gap can be. Utilita’s current schedules show non-half-hourly unrestricted variable electricity at 31.395p to 33.156p per kWh with 150.000p per day standing charge, while its deemed and out-of-contract unrestricted electricity is 29.884p to 31.562p per kWh with 115.000p per day standing charge depending on region. Its deemed and out-of-contract gas is published at 10.639p to 10.788p per kWh with 115.000p per day standing charge, and its half-hourly deemed electricity examples are £14.40 per day plus kVA. Yü Energy’s review page also gives out-of-contract examples of roughly 25p to 30p per kWh for electricity and 6p to 9p per kWh for gas.

The key lesson is simple: do not drift past renewal. Compare business energy suppliers early, because deemed and out-of-contract pricing can wipe out any savings you thought you had secured on the previous deal.

How to choose the best business energy supplier

Start with your latest bill and gather your annual kWh usage, meter numbers, current unit rates, standing charges and contract end date. A recent bill will tell you how much energy you use and helps you work out what type of contract you need.

Then decide what matters most. If your priority is the cheapest business energy supplier, compare whole-contract cost. If your priority is sustainability, compare renewable business energy suppliers and ask how green claims are evidenced. If your priority is operational complexity, focus on suppliers that are stronger on half-hourly, multi-site or export arrangements.

Finally, compare early. The best time to compare is usually three to six months before a contract ends, helping businesses avoid rolling onto deemed rates. Octopus also says businesses can choose supply dates up to 6 months in the future, which shows that early contracting is already part of the market.
