Utilita vs Octopus Energy

Utilita and Octopus Energy are the two names that come up most often when a prepayment household looks at smart pay-as-you-go. They are not the same kind of company. Utilita is a prepayment specialist, and it is currently the subject of an open Ofgem enforcement investigation into its compliance with the rules on installing and using prepayment meters, opened in November 2024¹. Octopus Energy is the largest supplier of electricity in the UK and the second largest for gas, serving around 7.8 million customers, or one in four households, as of December 2025².

The comparison therefore turns on more than price. On official satisfaction data, Octopus Energy was the only supplier with a significantly higher proportion of customers satisfied overall than the January 2026 average, and 86% of its customers said they were satisfied or very satisfied with customer service, against 76% for Utilita³. Utilita's own strengths sit elsewhere: emergency credit of £15 per fuel, friendly credit hours that run from 2pm to 10am on weekdays, and a business built around the meter type that many households actually have⁴.

What follows sets out the enforcement position first, then satisfaction, tariffs, smart metering, support for vulnerable customers and the practical questions of contact and equipment. The lens throughout is what each supplier does for a household's control of its own energy, and what dependence remains.

An Ofgem enforcement investigation into Utilita is open

Ofgem opened an enforcement investigation into Utilita in November 2024, examining the company's compliance with the rules around the installation and use of prepayment meters¹. The investigation is open, which means no finding has been made. It is a compliance process, not a verdict, and it sits alongside the wider market compliance review of prepayment meter installations that Ofgem has published.

The significance for a household is procedural. Ofgem's stated position is that if it thinks a supplier or network operator has not met certain rules, it will start an investigation, and its formal enforcement powers include opening investigations, making orders and imposing penalties⁶. Those powers are the response to non-compliance and suspected non-compliance, and they are set out in the regulator's own performance reporting⁸. An open investigation is therefore a live regulatory process with real consequences available at the end of it, but it is not itself a determination that anything went wrong.

Prepayment installation is a sensitive area because the rules restrict when a supplier can move a household onto a prepayment meter without permission. Where that has happened and a household is unhappy with how the supplier handled the complaint, the escalation route is the Energy Ombudsman⁹. The Ombudsman also shares data and insight with Ofgem under a memorandum of understanding when it sees evidence of potentially unfair practice, so complaints about prepayment conduct can feed into the regulator's picture even where the individual dispute is resolved separately.

For a household weighing the two suppliers, the practical reading is this: Utilita's prepayment expertise is genuine and long-standing, and the regulatory scrutiny of how that business is conducted is also genuine and current. A household that values a supplier with no open enforcement investigation on this subject has a clear reason to look at Octopus Energy. A household already on a Utilita prepayment meter has no reason to panic, but it has a reason to keep its own records of any meter exchange, the date it was done and whether permission was given.

Customer satisfaction: what the official surveys show

Ofgem publishes supplier-level satisfaction findings, and they are the most reliable comparison available because they are drawn from a consistent survey rather than from a supplier's own marketing. In the January 2026 findings, Octopus Energy was the only supplier with a significantly higher proportion of customers satisfied or very satisfied overall than the average, and it also had a significantly higher proportion satisfied with customer service and a significantly lower proportion dissatisfied with customer service than the average³. Its customer service satisfaction stood at 86%, against 76% for Utilita, whose dissatisfied or very dissatisfied figure was 8%³.

The July to August 2025 findings tell a similar story. Octopus Energy was the only supplier significantly above the GB average for overall satisfaction at 95% confidence, with 90% of respondents satisfied or very satisfied overall and 84% satisfied with customer service¹¹. Utilita's overall satisfaction in the same wave was 76%, from a sample of 112 respondents¹¹. The sample size matters: 112 respondents is a small base, and the January 2026 wave used 166 Utilita respondents³. Small samples produce wider margins, so a few percentage points of difference between the two suppliers in any single wave should not be over-read.

Earlier data shows the picture is not fixed. In the July 2024 findings, Octopus Energy and Utilita were the only suppliers with a significantly higher proportion of customers satisfied or very satisfied overall compared with the July 2024 average¹². Utilita has therefore performed well in official measurement before, and its position relative to the average has moved since. Which? separately scores Utilita at 68% overall in its own assessment, with a complaints score of 7 out of 15¹³.

What this means for independence is limited but real. Satisfaction data measures how a supplier behaves when something goes wrong: how quickly it answers, how it handles a dispute, whether a household has to escalate. A prepayment household has less room for a slow supplier than a direct debit household, because a meter that is not topped up correctly stops supplying. On the official evidence, Octopus Energy's customer service scores are stronger and more consistently above average, while Utilita's are respectable but more variable.

Tariffs: no standing charge options, at a price

The tariff question between these two suppliers is not a simple like-for-like comparison, because no published unit rate or standing charge is available for either supplier's standard variable or fixed products. Prices are quoted by the supplier or by a comparison service at the point of enquiry, and any figure quoted here would be out of date before it was read. What can be compared is structure.

Octopus Energy's Intelligent Octopus tariff has six hours of cheaper electricity overnight². That is a time-of-use structure, and it rewards a household that can shift load, such as by charging a car or running appliances overnight. It is a different proposition from a flat prepayment tariff, and it depends on the household having the appliances and the routine to use it.

On the export side, the Smart Export Guarantee annual report for Year 5 records that the lowest tied and untied tariff rates were 5p/kWh (Octopus) and 1p/kWh (E Energy) respectively¹⁴. Utilita's registered SEG installations numbered 83, among the lowest of any supplier, with E Energy at zero¹⁴. A household with solar panels therefore has a practical reason to look at which supplier actually operates in the export market at scale, and on this evidence Octopus Energy does and Utilita barely does.

The structural point about prepayment is that a prepayment tariff removes the standing charge question only in the sense that the cost is recovered through the unit rate or a daily charge deducted from credit. A household on a prepayment meter pays for what it uses as it uses it, which gives tight control over cash flow but no protection against a high unit rate. The absence of a published price in the official record means the only reliable comparison is a quote obtained for the specific property, region and payment method.

Smart meters and prepayment: Utilita's core business

Smart meters can operate in credit or prepayment mode, and they are free to use and available for both payment-on-account and prepay customers¹⁵. That single fact explains why prepayment specialists exist at all: the smart meter removes the need for a key or card and lets a prepayment household top up remotely, see usage in near real time and switch between credit and prepayment modes without a meter exchange.

Utilita's business is built on that. Which? notes that several suppliers focus on customers with prepayment meters, naming Utilita among them². The company has also argued in Ofgem's consumer vulnerability work that smart meter insights provide clear and accessible information that helps consumers understand their usage, and that smart meter data provides a non-digital pathway to improved insight for consumers who may be harder to reach¹⁷. That is a meaningful point for energy independence: a household that can see its own consumption without an app or a smartphone has more control than one that cannot.

Octopus Energy's position is different. It is a full-market supplier with around 7.8 million customers, having taken on 1.5 million customers from the failed supplier Bulb and 1.3 million from Shell². Its smart meter offer is part of a broader product set that includes time-of-use tariffs and export tariffs, rather than a prepayment specialism.

The dependence that remains is worth stating plainly. A smart meter in prepayment mode still depends on the supplier's systems, the top-up channel and the mobile network that carries the data. A household that tops up through an app depends on the app working. A household that tops up at a shop depends on the shop's terminal. Neither supplier removes that chain, and neither removes the standing relationship with a licensed supplier, because the meter itself is registered to one.

Support for vulnerable customers: PSR, emergency and friendly credit

Both suppliers operate within the same regulatory framework for vulnerable customers, and the framework is where the practical differences show. Ofgem's expectation is that vulnerable needs should be proactively identified by energy suppliers and additional support provided wherever appropriate¹⁵. The Priority Services Register is the main route, and official guidance is that a household signs up by contacting all of its utility suppliers directly¹⁸. Registration is not automatic and is not shared between suppliers.

Emergency credit is the figure most prepayment households ask about. Utilita's emergency credit is £15 per fuel, according to Which? research published in January 2026, against £10 per fuel at Ecotricity⁴. That is per fuel, so a dual-fuel household can draw on gas and electricity separately. Emergency credit is recovered from the next top-up, and it is a bridge rather than a solution.

Friendly credit hours are the other mechanism. Utilita applies friendly credit on all meters between 2pm and 10am on weekdays, all day at weekends and bank holidays, and all day on Mondays for customers who have been with the company more than three years⁴. Utility Warehouse, by contrast, applies friendly credit between 4pm and 10am on weekdays on smart meters and many traditional electricity meters, with no friendly credit at all on traditional gas meters or on traditional electricity meters manufactured before 2008⁴. The comparison shows that friendly credit is a supplier policy rather than a universal right, and that the hours and the meter types covered vary.

Beyond the supplier, Additional Support Credit is described by Ofgem as a vital tool to support prepayment customers in vulnerable situations who have self-disconnected or are at risk of doing so¹⁹. The Citizens Advice Extra Help Unit supports vulnerable consumers by raising complaints with energy suppliers on their behalf, particularly where there is a risk of disconnection or complex personal circumstances, and it takes referrals²⁰. In Scotland, the Scottish Welfare Fund crisis grants are a separate route for an unexpected crisis²¹. Ofgem's own recommendation to suppliers is to move more customers into sustainable repayment arrangements that reflect ability to pay, while ensuring short-term support is targeted at consumers most at risk of harm¹⁷.

Contacting Utilita and replacing a faulty monitor

Utilita Energy Limited's telephone number is 0330 053 5669, listed in Ofgem's Feed-in Tariff licensee contact details²². That register is the number the company gives to the regulator, which makes it a more dependable starting point than a number found on a comparison site.

A replacement in-home display is a chargeable item at Utilita. Which? records the price of a replacement energy monitor from Utilita at £39.99, against £30 at Utility Warehouse⁵. Octopus Energy replaces a monitor free of charge after twelve months if it has physical problems, a fault has occurred or the customer has lost it, and Utility Warehouse does the same unless the household has already had multiple replacement monitors⁵. The twelve-month threshold is the point at which the free replacement applies, not a warranty period for the original device.

Complaints follow a fixed route. The complaint goes to the supplier first, and the household should keep the date it was raised. The Energy Ombudsman will only take a dispute that has already been through the supplier, with sufficient evidence including the date the complaint was raised, and the company name must match the account holder's bill²³. Where a prepayment meter has been installed without permission and the household is unhappy with how the supplier handled the complaint, the Ombudsman is the escalation route⁹. The Ombudsman stops accepting new disputes about a company once it has ceased to trade, which is why timing matters²⁶.

Utilitate Energy ceased trading: what it means for customers

Utilitate Energy is not Utilita. The names are close enough to cause confusion, and the confusion matters because the two companies have entirely different status. Utilitate Energy's trading period ended on 15 October 2024, and the Energy Ombudsman records it as a ceased supplier²⁶. Utilita Energy Limited continues to trade and is the subject of the open Ofgem investigation described above.

When a supplier ceases trading, customers are moved to a new supplier through the supplier of last resort process, and the Energy Ombudsman stops accepting new complaints about the failed company²⁶. The same pattern applies across the market: the Ombudsman is not accepting new disputes about Orbit Energy, Entice Energy, Yorkshire Energy or Tonik Energy following their ceasing to trade¹³. Other companies in the Ombudsman's register are recorded as inactive or as having ceased trading, including UtilityCloudLive and Npower Business²⁷. Foxglove Energy, separately, is now known as Outfox Energy²⁹.

The wider market context is that supplier failure is routine rather than exceptional. Small supplier Tomato Energy ceased trading in November 2025 after finding its rapid growth unsustainable². Octopus Energy's own scale was built partly on absorbing failure: it took on 1.5 million customers from Bulb and 1.3 million from Shell, and it is now the largest supplier of electricity and the second largest for gas after British Gas². For a household, the lesson is that the supplier's financial position and regulatory standing are part of the energy independence picture, not separate from it. A household that wants to understand what happens when a supplier fails can read what happens if my energy supplier goes bust and energy supplier failures.

Where each supplier leaves a household dependent

Neither supplier makes a household self-sufficient. Both sit between the household and the network, and both depend on systems the household does not control.

Utilita's dependence profile is narrow and deep. The household depends on the prepayment top-up chain, on the meter's communications, and on the supplier's credit policies, including emergency credit and friendly credit hours. Those policies are set by the supplier and can change. The open Ofgem investigation adds a regulatory dimension to that dependence, because the rules being examined are the rules that govern how the household was placed on the meter in the first place¹.

Octopus Energy's dependence profile is broader. A household on a time-of-use tariff depends on the tariff structure continuing, on the smart meter reporting half-hourly data, and on the supplier's app and billing systems. The export side adds a further dependency for solar households: the Smart Export Guarantee rate is set by the supplier, and the lowest tied rate recorded in Year 5 was 5p/kWh from Octopus, against 1p/kWh untied from E Energy¹⁴. A household with panels is therefore selling into a market where the rate depends on which supplier it chooses.

What both suppliers offer is visibility. Smart meters in either mode give a household its own consumption data, and Utilita has argued that this data provides a non-digital pathway to insight for consumers who might otherwise be excluded¹⁷. That is the closest thing to independence either supplier provides: the ability to see what is being used, when, and at what cost, without waiting for a bill. The rest, including the unit rate, the standing charge and the credit terms, remains a matter of the contract. Households weighing the wider market can compare challenger energy suppliers and the UK energy supplier market share.
