Octopus vs Utilita: Business Energy Comparison

Octopus Energy and Utilita are both best known for household energy, but their business arms work very differently. Octopus Energy for Business says it passed 100,000 business customers in early 2026, sells only direct and doesn't work with brokers or price comparison sites.

Utilita Business serves more than 8,000 customers and is still widely described online as a pay-as-you-go supplier. In practice, that no longer applies to new business customers: Utilita's own business help centre says pay-as-you-go and prepayment meters aren't available to them, and it now sells fixed contracts of 12, 24 or 36 months backed by a compulsory smart meter.

TLDR: Octopus is the better choice for most small businesses. It has the wider tariff range, stronger service ratings, and renewable-backed electricity as standard. Utilita is worth a quote if you want a simple 1-3 year fixed contract with a named account manager, billing across several sites, or on-site solar and battery storage.

This business energy comparison looks at tariffs, contract length, pricing structure, renewable credentials, customer service, smart tech and fees. We looked into both suppliers' published terms, rate schedules and independent ratings in September 2026, so you can weigh Octopus against Utilita for your company's energy supply.

Octopus vs Utilita at a Glance

Which Supplier Offers Better Tariffs?

Neither Octopus nor Utilita publishes a fixed rate card for new business customers, because pricing depends on:

• Business location

• Annual consumption

• Industry type

• Meter type

• Contract length

• Credit profile

• Regional distribution charges

It's worth noting that the two suppliers structure their ranges very differently. Utilita keeps to fixed contracts, plus a variable rate for accounts that run past their end date. Octopus offers standard fixed contracts alongside smart time-of-use pricing, a no-standing-charge trial, export tariffs and products for large sites.

Does Utilita Offer Pay-As-You-Go?

Several third-party guides say it does, and one review goes further and says Utilita stopped taking fixed business contracts after it sold more than 40,000 credit customers to EDF in November 2025. We found that neither claim holds up against Utilita's own pages. Its help centre says pay-as-you-go meters aren't available to new customers and adds that they're a poor fit for businesses that need a continuous supply, because supply can shut off if credit runs out.

The sale announcement covers credit customers and doesn't mention business fixed contracts, and Utilita's business pages, checked in September 2026, list fixed terms of 12, 24 and 36 months. When we speak to business owners, we find that many still expect prepayment from Utilita, because that's the model it built its name on at home.

Utilita Tariffs

Business Fixed Contracts

A fixed unit rate and standing charge for 12, 24 or 36 months. Small businesses can get an online quote, and larger sites get a bespoke quote valid for 48 hours. Utilita says the rate won't change mid-term, but its help centre also warns that regulated network charges such as Transmission Network Use of System (TNUoS) charges can still be passed through on a fixed contract, so ask how yours is treated.

Best for:

• Businesses that want one predictable rate and a named contact

• Multi-site operators who want a single consolidated bill

• Sites planning solar or battery storage alongside their energy contract

Business Variable Rates

The rate you move onto if your fixed contract ends and you haven't renewed. It has no fixed end date, and Utilita says your costs will likely be higher than on a fixed deal.

Group Billing and Payment Options

Group Billing lets a multi-site business pay through a single or group variable Direct Debit. Single sites can choose a Monthly Fixed Direct Debit, which splits the year's estimated cost into 12 equal payments, or a Variable Direct Debit that follows actual usage.

Large Business Contracts

Bespoke pricing built around your actual usage, fixed for one to three years, with consolidated billing. Utilita says it supplies public sector clients such as the NHS, the Ministry of Defence and local councils.

Octopus Tariffs

Business Fixed

A fixed-rate contract for electricity, gas or both, available for 12, 24 or 36 months. Octopus says a fixed price is never changed during the term and that it adds no extra fees.

Shape Shifters: Trio

A time-of-use tariff with three set prices: a night rate from midnight to 7 am, a day rate from 7 am to 4 pm and 7 pm to midnight, and a peak rate from 4 pm to 7 pm. Octopus describes this as 21 hours of cheaper electricity every day.

Shape Shifters: Agile

The more dynamic version. Prices change every half hour and are published 24 hours ahead. You need a working smart meter, an up-to-date Direct Debit and no overdue debt to join either version.

Best for:

• Bakeries, dry cleaners, breweries and other businesses that already use most of their energy off-peak

• Sites that can move equipment or prep work away from 4 pm to 7 pm

• Businesses with a working smart meter and a clean payment history

No Standing Charge Tariff

A trial product with a standing charge of £0 a day, where the fixed cost moves into a higher unit rate. Octopus says it's open to electricity bands 2, 3 and 4 on a fixed 12-month contract and doesn't need a smart meter. It's more likely to save money if your usage sits at the lower end of your band. Octopus launched it in October 2023 as a trial, so check that it's still offered for your band.

Export, Electric Match and Wind Works

Octopus offers smart export tariffs for businesses that send power back to the grid, Electric Match for large commercial users who want traceable renewable supply matched within half an hour of generation, and Wind Works, where Octopus funds, builds and operates renewable technology at your premises.

Multi-Site Energy

Octopus lets you manage switching, renewals, bills and online account access for all your sites as one joint portfolio.

Tariff Comparison Table

Winner: Octopus, for the breadth of its tariff range, particularly for businesses that can shift usage or want a no-standing-charge option. Utilita is the simpler choice for a business that just wants a fixed price, a named contact and no decisions to make about time-of-use pricing.

How Do Contract Lengths Compare?

Octopus Contract Terms

Utilita Contract Terms

Contract Length Scorecard

Utilita publishes its exit formula, which makes it easy to check. It takes one twelfth of your estimated annual energy cost, applies 20% and multiplies by the months left. As a worked example using that formula, a business spending £3,600 a year on energy with eight months left would pay £480 to leave early. Octopus's help centre says some business tariffs carry an exit fee that falls each month you stay, and its business terms say early exit can include reasonable costs such as losses on forward energy contracts. The result is a fee that shrinks each month but only reaches zero at your end date. Ask either supplier for the exact figure before you sign.

Octopus vs Utilita Pricing Structure

Business energy quotes typically include:

Unit Rate

The price charged for each kWh (kilowatt hour) you use. Neither supplier publishes fixed business rates, so a live quote is the only reliable comparison. What both do publish is out-of-contract pricing, which shows what happens if you let a contract lapse. Utilita publishes its Business Variable rates as a PDF schedule, and a third-party analysis of its April 2026 schedule put unrestricted, non-half-hourly electricity at 39.195p to 40.956p per kWh depending on region, excluding VAT. Utilita has issued a newer schedule effective from 1 August 2026, so check the current version. Octopus shows its out-of-contract rates by postcode, so we can't give a single figure.

Standing Charge

The daily fee covering network connection and administration. Utilita sets it per quote, and the same April 2026 analysis put its published variable standing charge at 250p a day, excluding VAT. Octopus also sets it per quote, or charges £0 a day on its No Standing Charge Tariff.

Pass-Through Charges

May include:

• Network costs, as explained in our guide to pass-through and fully fixed energy contracts

• Balancing charges

• Government levies

Utilita's help centre says TNUoS charges changed from April 2026 and account for around 7% of electricity costs for many businesses, though this varies by connection and usage. Octopus says your fixed price won't change during the term, but its business terms still allow it to pass through some costs in defined cases, such as where your Supply Summary shows a pass-through. Read that document before you sign.

Advance Payments and Credit Checks

Octopus typically takes an advance payment equal to about three months of estimated energy cost, rising to up to six months depending on your credit score, and refunds it at the end of the contract. Utilita doesn't publish an equivalent requirement in the pages we reviewed, though its broker FAQ confirms a credit check is part of the process, so ask what deposit or security your quote assumes.

VAT

Both suppliers quote prices excluding VAT. Most businesses pay 20% VAT on energy, and those using under 33 kWh of electricity or 145 kWh of gas a day can qualify for the reduced 5% rate with a declaration. It's worth noting that qualifying electricity supplies in Great Britain will be zero-rated for VAT from 1 October 2026 to 31 March 2027. That covers supplies that already qualify for the reduced rate, so a business paying the standard 20% won't see a change.

Pricing Transparency Comparison

Winner: Octopus, on quoting speed and the range of pricing structures on offer. On cost, there's no winner until you hold live quotes for your site. Octopus's advance payment is a real cash flow trade-off, and it's worth asking Utilita what security it expects. When we speak to business owners, we find that the gap between two quotes for the same site is often wider than the gap between the brands, which is why we'd always collect at least three.

Which Supplier Has Better Renewable Energy Credentials?

The two suppliers take opposite positions on green tariffs, and it's worth understanding both before you rely on a label.

Octopus Sustainability Initiatives

Offers:

• Electricity that Octopus describes as zero-carbon, included in its business tariffs as standard

• Electric Match, which matches consumption to chosen renewable generators within half an hour of generation, aimed at large commercial users

• Wind Works, where Octopus funds, builds and operates renewable technology at your premises

• Smart export tariffs for businesses with their own solar or battery storage

Pros

• A fuel mix listed by Citizens Advice as 0% fossil fuel, 15% nuclear and 85% renewable

• Renewable supply included in the standard offer, with no capital spend

• Products that go beyond a standard certificate claim for larger users

Cons

• Like any supplier selling a renewable-backed tariff, Octopus can't guarantee that electricity from a specific generator reaches your meter, outside products such as Electric Match

• Electric Match and Wind Works are aimed at large sites, not typical SMEs

Utilita Sustainability Initiatives

Offers:

• No green tariff for business customers. Utilita's green tariffs page argues that tariffs backed by Renewable Energy Guarantees of Origin (REGOs) can mislead customers, because the certificates can be traded separately from the electricity itself

• Commercial solar and battery storage, with flexible funding including a power purchase agreement (PPA)

• A Live Carbon Dashboard, which is being trialled with business customers, and a Net Zero target of 2030 for Utilita's own operations

Pros

• A clear, consistent position: it sells generation on your own roof rather than a certificate

• Solar cuts the electricity you draw from the grid directly. Utilita says its installations have saved customers more than £3 million

• A sustainability page that reports progress against targets each year

Cons

• If you want renewable-backed electricity without installing generation, Utilita doesn't offer it

• Its fuel mix, as listed by Citizens Advice, is 83% fossil fuel, 11% nuclear and 0% renewable, and that figure covers the whole company rather than business customers alone

• Solar needs suitable roof or land space, and the business carbon dashboard is still a trial

Sustainability Comparison

Winner: Octopus, for businesses that want renewable-backed electricity today without capital spend. Utilita makes a fair argument that a certificate doesn't change what's on the grid, and its solar route suits businesses with roof space and capital or funding to invest. If you report market-based Scope 2 emissions, ask your accountant or sustainability adviser which evidence they'll accept before you choose either route. Our renewable business energy guide covers the options in more detail.

Customer Service Comparison

Customer support can have a major impact on small businesses when problems arise. It's worth noting that Citizens Advice, Ofgem (the energy regulator) and Trustpilot mostly measure household customers, so none of these is a business-only score.

Octopus Business Support

Channels include:

• An online dashboard covering bills, meter readings and account management

• Phone and email support

• One portfolio view across multiple sites

Strengths

• Citizens Advice's January to March 2026 rating gives Octopus 3.67 out of 5 and 4th place, with 21.3 complaints per 10,000 customers and an average call wait of 1 minute 17 seconds

• In the Ofgem and Citizens Advice household survey of July to August 2025, 90% of Octopus customers were satisfied overall, and 84% were satisfied with customer service, against market averages of 82% and 76%

• A Trustpilot rating of 4.8 out of 5 from over 870,000 reviews, as of September 2026

Weaknesses

• Billing and metering was Octopus's lowest Citizens Advice sub-score, at 3.4 out of 5

• The Trustpilot volume is mostly household, and we couldn't find a business-only independent score

Utilita Business Support

Channels include:

• A named account manager for every business customer. Utilita says there are no chatbots or call centres involved

• A dedicated Business Renewals Team that contacts you 60 days before your contract ends

• My Utilita Online for bills and payment history, available to single-site accounts only

Strengths

• Citizens Advice records an average call wait of about 1 minute, scoring Utilita 4.4 out of 5 for contact waiting time

• In the July to August 2025 household survey, 76% of Utilita customers were satisfied overall and 72% with customer service. Both are slightly below the market averages, though Ofgem didn't flag either as a significant difference, and the sample was only 112 people

• A Trustpilot rating of 4.3 out of 5 from about 112,000 reviews, as of September 2026, although it's a household-led score

Weaknesses

• Citizens Advice's January to March 2026 rating gives Utilita 2.35 out of 5 and 15th place, with 164 complaints per 10,000 customers, roughly eight times Octopus's rate, and 2.2 out of 5 for billing and metering

• Utilita has said in the past that the Citizens Advice star rating contradicts other assessments, including Ofgem's and Trustpilot's, so it's worth reading the sub-scores rather than the headline alone

• The named account manager promise is Utilita's own claim, and we found no independent business data to test it

Customer Service Scorecard

In our experience, billing and metering is the part of these ratings worth weighing most. When we speak to business owners who've had a poor run with a supplier, we find that billing errors, slow fixes for meter faults and surprise charges at renewal come up more often than the unit rate itself. Octopus's 3.4 out of 5 is its weakest sub-score, but Utilita's 2.2 out of 5 sits alongside the highest complaint volume in this comparison.

For context, Ofgem's 2025 business research found 68% of businesses satisfied with their supplier's service, up from 62% in 2024.

How Do Smart Meters and Tech Compare?

Octopus Technology Solutions

• SMETS2 (second-generation) smart meter installation, with an average wait of 4 to 6 weeks for single-phase meters

• An online dashboard for bills, meter readings and account management

• Shape Shifters tariffs that use half-hourly smart meter data to price your electricity

• Octopus Fleet, launched in February 2026, which combines the Electroverse public charging network, a Fleet Charging Card, a Business Payments Card and a home charging reimbursement scheme

• Chargers, rooftop solar and battery products

Ideal For

• Businesses that can act on half-hourly pricing to cut their bills

• EV fleet operators who want one card and one invoice

• Businesses with, or planning, on-site solar or battery storage

Utilita Technology Solutions

• A compulsory smart meter under Utilita's terms, installed at no extra cost in about two hours. You contact Utilita to confirm availability for your site

• Bills based on actual usage, so there are no estimates or bill corrections

• Up to 12 months of historical smart meter data at no cost, through My Utilita for single sites or by email for multi-site accounts

• Commercial solar and battery installation, and EV charging installation including solar-powered canopies

Ideal For

• Businesses that want smart-meter billing and no estimated bills

• Sites planning solar, batteries and EV charge points from one company

• Businesses that don't need time-of-use pricing

Technology Comparison

Winner: Octopus, for tariffs that put smart meter data to work and for its fleet tools. Utilita is worth a closer look if you want a meter, solar and chargers from one company, though a compulsory smart meter is a barrier if your site can't take one. For larger sites, our guide to half-hourly meters explains what changes.

Business Energy Charges

Additional fees may apply with either supplier.

Common Charges

Key Consideration

Businesses should avoid rolling onto out-of-contract or deemed rates, which are typically far more expensive than a fixed contract, whichever supplier you choose. In practice, Utilita's 60-day renewal notice helps you plan, while Octopus's advance payment ties up cash, so it's worth checking which of those matters more to your business.

Pros and Cons of Octopus

Advantages

Stronger Independent Service Scores
A Citizens Advice score of 3.67 out of 5, 4th place in the January to March 2026 table, and 21.3 complaints per 10,000 customers.

Smart and Flexible Tariffs
Shape Shifters Trio and Agile, plus a No Standing Charge trial tariff, give businesses that can flex their usage more choice than a standard fixed contract.

Renewable-Backed Supply as Standard

Disadvantages

Advance Payment Upfront
Typically about three months of estimated energy cost, up to six depending on credit score, refunded at the end of the contract.

Direct Only, So No Broker or Comparison Site Quote
Octopus says it doesn't work with brokers or price comparison sites, so you'll need to request its quote yourself and compare it by hand.

Smart Tariffs Reward Engagement
Shape Shifters need a working smart meter and pay off most for businesses that can shift usage. A set-and-forget business may not see the full benefit.

Exit Fees on Some Tariffs
Fees vary by tariff, so check the figure for your contract before you sign.

No Green Tariff and No Renewable Fuel Mix
Utilita doesn't sell renewable-backed business electricity, and its company-wide fuel mix is listed at 0% renewable.

Compulsory Smart Meter and Limited Online Access
You must accept a smart meter under Utilita's terms, and My Utilita Online is for single-site accounts only.

Exit Fee and Possible Pass-Through Charges
Leaving early costs 20% of your monthly price for each month remaining, and regulated charges such as TNUoS can still be passed through on a fixed contract.

Which Supplier is Better for Which Business Types?

Octopus vs Utilita: Side-by-Side Summary

Key Questions to Ask Before Deciding

Before signing a business energy contract, compare:

1. Is my price fully fixed, or can regulated charges such as TNUoS be passed through?

2. What is the standing charge, and is there a no-standing-charge option?

3. Is an advance payment or deposit required, and how much?

4. What is the exit fee, and how is it calculated?

5. What happens when my contract ends, and how much notice will I get?

6. Can my premises take a smart meter, and how long is the wait?

7. Can I shift usage away from peak hours to benefit from a smart tariff?

8. Is the renewable claim backed by certificates, matched supply or my own generation?

9. Will I have a named contact, or a general helpline, when something goes wrong?

10. What do independent sources, not just the supplier's own website, say about its service?

Octopus vs Utilita FAQs

Is Octopus or Utilita cheaper for business energy?

Neither publishes a fixed rate card, so there's no single answer. Both price each contract by postcode, usage, meter type, contract length and credit profile. The only reliable comparison is live quotes for your own site. Octopus sells direct, so request its quote separately and set it beside any others you collect.

Does Utilita offer pay-as-you-go for business?

No. Utilita's business help centre says pay-as-you-go and prepayment meters aren't available to new customers. It sells fixed contracts of 12, 24 or 36 months, and moves you onto Business Variable rates if a fixed contract ends without renewal.

Is Octopus on price comparison sites?

No, according to Octopus. Its business page says it doesn't work with energy brokers and won't appear on price comparison websites, so its quote has to come from Octopus directly.

Does Utilita offer renewable business energy?

Not as a tariff. Utilita says it doesn't sell green tariffs to business customers and argues that certificate-backed tariffs can mislead. It offers commercial solar and battery storage instead. Citizens Advice lists its company-wide fuel mix at 0% renewable.

Do Octopus and Utilita require a smart meter?

Utilita does. Its terms require business customers to have a smart meter, which it installs at no extra cost in about two hours. Octopus needs one for Shape Shifters, but its No Standing Charge Tariff doesn't require one.

Do Octopus and Utilita charge exit fees?

Yes, on fixed contracts. Utilita charges 20% of your monthly price for each month remaining. Octopus's fee varies by tariff and falls each month you stay, so ask for the figure before you sign.

Does Octopus require an advance payment?

Yes. Octopus usually takes an advance payment equal to about three months of estimated energy cost, up to six months depending on your credit score, and refunds it at the end of the contract. Utilita doesn't publish an equivalent requirement, though a credit check is part of the process.

Which has better customer service, Octopus or Utilita?

Octopus, on the independent household measures we checked, apart from call waiting time, where Utilita's average of about one minute is slightly shorter. Citizens Advice's January to March 2026 rating gives Octopus 3.67 out of 5 (4th), and Utilita 2.35 out of 5 (15th), and Ofgem's July to August 2025 survey found 84% of Octopus customers satisfied with customer service against 72% for Utilita. Utilita's named account manager model may feel different for a business, but we found no independent business data to test it.

Is Utilita a good fit for multi-site businesses?

Yes. Utilita's Group Billing puts multiple sites on a single or group variable Direct Debit, and larger portfolios get bespoke pricing. Its online account is single-site only, so multi-site customers rely more on their account manager.

Alternatives to Octopus and Utilita

• If you want to see how Octopus compares against another major supplier with a broad SME focus, our Octopus vs British Gas comparison looks at that trade-off directly.

• If renewable credentials matter most to you, our Octopus vs E.ON Next comparison covers another supplier with a strong sustainability story.

• If you're weighing Utilita against a multi-service supplier, our Clear vs Utilita comparison covers that pairing.

Verdict: Octopus or Utilita for Business Energy?

Choose Octopus if you want:

• Stronger independent service ratings on most measures

• Smart and time-of-use tariffs, or a no-standing-charge option, if you can flex your usage

• Renewable-backed electricity as standard, with no capital spend

• A broader toolkit for multi-site management, EV fleets and on-site generation

Choose Utilita if you want:

• A simple 1-3 year fixed contract with a named account manager

• Group Billing across several sites on a single or group Direct Debit

• Solar, battery storage and EV charge points from the same company as your energy

• To buy through a broker, or to avoid a large advance payment (ask Utilita what security it expects)

For most small businesses, day-to-day supply quality differs little between suppliers, because all providers use the same national grid infrastructure. The clearer dividing line here is service record and product range. Octopus outperforms Utilita on the independent household measures we found, apart from call waiting time, and it offers more tools for businesses willing to engage with them. Utilita's case rests on a simple fixed contract, a named contact and a solar route, and it's no longer the pay-as-you-go supplier many guides still describe.

When we speak to business owners weighing the two up, the service record is usually what settles it, followed by whether they can live with a smart meter and an advance payment. Either way, get live quotes before you sign. Octopus sells direct only, so request its quote on its own site and set it beside the quotes you collect through our business energy comparison tool.
