Octopus Energy for Business is the non-domestic arm of one of the few UK suppliers that publishes its tariff rates online before a customer signs. That single editorial choice changes the negotiation posture for any SME looking at the market in 2026. The verdict below is built from Ofgem's complaint data, the supplier's own published rate cards, and the way the offer actually behaves once a quote turns into a contract.
TL;DR
- Octopus Energy for Business publishes indicative unit rates and standing charges by region on its website, a transparency move most non-domestic suppliers in the UK still resist as of May 2026.
- The offer splits between microbusiness (under 100,000 kWh gas or 293,000 kWh electricity, per Ofgem's definition) and larger SME, with different contract lengths and termination windows applying to each.
- In Ofgem's quarterly complaint data tables, Octopus has consistently sat in the lower complaints-per-100,000-customer range relative to the legacy Big Six, though non-domestic figures are reported less granularly than domestic.
- Fixed terms of 12, 24 and 36 months are available; standing charges vary materially by Distribution Network Operator region, particularly between South West (WPD) and North Scotland (SSEN).
- The catch is what is not on offer: no full Power Purchase Agreement structuring, no half-hourly bespoke pricing below a certain consumption threshold, and limited bespoke risk-managed products versus an industrial-and-commercial specialist.

Where Octopus Energy for Business actually sits in the market
The UK non-domestic supply market in 2026 is split into three rough layers. At the top, the industrial-and-commercial layer is dominated by SSE Business Energy, EDF Business, British Gas Business, npower Business Solutions and a handful of specialists offering flex contracts and PPA structuring. In the middle, the SME layer is where most named consumer brands compete: Octopus, E.ON Next Business, Pozitive Energy, Yu Energy, Opus Energy, and a long tail of smaller suppliers. At the bottom, microbusiness sits under tighter Ofgem rules, including the 2022 ban on automatic rollovers and the requirement to publish a principal contract terms summary.
Octopus Energy for Business positions across the SME and microbusiness layers, with a clear product line for sites consuming roughly 5,000 kWh to several million kWh per year.
The defining trait is information disclosure. On its public site, Octopus lists indicative business unit rates and standing charges broken down by region and meter type, alongside a downloadable principal terms document. That transparency is rare. British Gas Business, EDF Business and most brokers price by individual quote without a published rate card, partly because non-domestic pricing is genuinely day-by-day and partly because opacity protects margin.
Octopus publishes its business rates online while most of its competitors do not.
In practice, the published Octopus rates serve as an anchor. An SME quoted by a broker at 28p per kWh for a fixed 24-month deal in May 2026 can now check whether that is meaningfully above or below the Octopus published rate for the same region and meter profile. That single comparison changes whether the broker's quote feels competitive or excessive.
The microbusiness offer and what Ofgem rules force
Ofgem defines a microbusiness as one that meets at least one of: fewer than 10 employees and annual turnover or balance sheet under EUR 2 million; consumption under 100,000 kWh of electricity per year; or consumption under 293,000 kWh of gas per year. Most UK SMEs in the under-50-employee bracket fall inside this definition for at least their electricity meter.
For microbusinesses, suppliers including Octopus are bound by Ofgem's microbusiness Standards of Conduct and the rules introduced through the 2022 Non-Domestic Market Review changes. The relevant rules require a clear principal terms summary, a ban on automatic rollover into a new fixed term, a documented complaints procedure, and Energy Ombudsman jurisdiction over disputes.
Octopus's microbusiness offer in May 2026 maps cleanly to these requirements. The principal terms document on its site sets out unit rate, standing charge, contract length, termination window, and out-of-contract rate exposure. The termination window for microbusiness contracts at Octopus is at the longer end of the market range, which in practice gives an SME more time to switch without slipping into deemed rates.
The catch is what microbusiness protection does not cover. The ban on automatic rollover does not mean a microbusiness cannot end up on out-of-contract rates if it does nothing. Ofgem's rule says the supplier cannot lock the customer into a new fixed term automatically; it does not say the customer keeps paying the old fixed rate. When the fixed term ends, the meter rolls onto deemed or out-of-contract rates, which at most suppliers sit materially above a freshly negotiated fixed deal.
The SME and larger non-microbusiness offer
Above the microbusiness threshold, Octopus offers fixed contracts of 12, 24 and 36 months for SMEs and larger non-microbusiness sites. Pricing here is quote-based rather than purely published rate card, reflecting the fact that wholesale costs at the larger consumption brackets are typically passed through with less smoothing.
The 24-month fixed sits as the workhorse product for most SMEs in the 100,000 to 1,000,000 kWh per year band. Standing charges in this band are quoted daily and vary by DNO region. In the South West (WPD region), the standing charge for an LV non-half-hourly business meter has historically sat above the average across England; in central London (UKPN), the unit rate is typically slightly higher but the standing charge slightly lower than the regional average, reflecting distribution network charge structures published by Ofgem in its periodic Targeted Charging Review materials.
Half-hourly metered sites, which since the April 2017 P272 change include most non-domestic meters in profile classes 05 to 08, get a different quote process. Octopus prices half-hourly contracts off the customer's actual half-hourly consumption file, which is the same approach used by industrial-and-commercial specialists. The difference is the level of bespoke risk-managed structuring on offer.
For an SME with predictable consumption and no appetite for wholesale market exposure, the Octopus fixed offer competes directly with E.ON Next Business, Pozitive Energy and the standard fixed products at the larger legacy suppliers. For a manufacturer with a daytime-heavy load profile and an appetite to manage risk actively, the Octopus standard offer is not the right fit.
Complaints, service and the Ofgem data
Service quality in non-domestic supply is harder to read than in the domestic market. Ofgem publishes a quarterly complaints data table for domestic suppliers showing complaints per 100,000 customers received, resolved on the day, and resolved within eight weeks. The non-domestic equivalent is less granular and the Ombudsman Services Energy annual report covers both domestic and non-domestic complaints together in much of its top-line reporting.
What the Ofgem data does show is that across the suppliers that report comparable figures, Octopus has consistently appeared in the lower complaints-per-100,000-customer band on the domestic side. Non-domestic performance broadly tracks the same supplier infrastructure, so the inference for SME service is reasonable but not guaranteed.
The Energy Ombudsman, which is the approved Alternative Dispute Resolution body for the sector, handles microbusiness disputes once the supplier's internal complaints process is exhausted or has run for eight weeks. Octopus, like all licensed suppliers, is bound by the Ombudsman's decisions on microbusiness cases. Non-microbusiness SMEs do not get the same automatic Ombudsman access, which is one of the more important practical differences between the two categories.
One specific pattern reported in Citizens Advice's energy work is that complaints volume in the non-domestic space spikes around contract end and renewal moments. Suppliers including Octopus issue contract-end-date letters typically 60 to 120 days before the contract ends, and the quality of that letter (whether it is clear about the termination window, the out-of-contract rate, and the renewal price) is one of the main service touchpoints that drives complaints.
Published rates, standing charges, and the regional spread
The standing charge in non-domestic electricity is where regional variation is most visible. The figures below are indicative of the spread visible in published business rate cards in May 2026 and the broader Ofgem-reported regional charge structure for low-voltage non-half-hourly meters. Exact figures move with each rate card update.
| DNO region | Indicative standing charge band (p/day) | Notes |
|---|---|---|
| London (UKPN LPN) | Lower-mid | Higher unit rates offset lower fixed daily cost. |
| South West (NGED WPD) | Higher | Rural network density drives DUoS recovery. |
| North Scotland (SSEN North) | Highest | Distribution costs and geography push standing charge above national average. |
| North West (ENWL) | Mid | Sits close to England and Wales average. |
| East Midlands (NGED EMID) | Mid | Standard urban/rural mix. |
For a microbusiness in Truro running a small retail site, the standing charge can be the single biggest line item on a low-consumption bill, often outweighing the unit rate cost over a quiet trading month. For a high-consumption manufacturer in Manchester, the standing charge is a rounding error and the unit rate is everything.
Octopus's published rates make this trade-off visible up front, which is the practical value of the transparency move. Brokers quoting blended unit rates without breaking out the standing charge can hide where the cost actually sits.
What the offer does not include
Honest assessment of Octopus Energy for Business has to be clear about gaps. There are three.
First, full PPA structuring is not part of the standard offer for sites below the industrial-and-commercial threshold. A corporate Power Purchase Agreement, where a buyer contracts directly with a generator for renewable power over a 10 to 15 year term, sits with specialist intermediaries and the industrial-and-commercial teams at SSE, EDF and a handful of specialists. An SME wanting a CPPA structure in 2026 is not the natural customer for the Octopus SME desk.
Second, fully bespoke risk-managed products, where wholesale exposure is split into tranches and locked in over a forward curve, are not the standard SME offer. Octopus does run flex products at the larger end, but the published rate card and standard fixed offer dominate the SME experience.
Third, broker-channel customers may find pricing routes different from direct customers. Octopus does work through some Third Party Intermediaries, but the published direct rate card is the cleanest reference point for what the supplier is willing to charge without commission baked in.
The verdict, framed honestly
For a UK SME consuming between roughly 20,000 and 500,000 kWh of electricity per year, on a single-rate or day-night meter, wanting a fixed contract of 12 to 36 months, Octopus Energy for Business is a credible and transparent option that benchmarks well against the published competition. The transparency on rates, the microbusiness contract terms, the in-house technology stack, and the historical complaints record are the four supporting reasons. The published rate card lets a buyer sanity-check any broker quote against a real number, not a market average. The principal terms document spells out the termination window, the out-of-contract rate, and the early termination clause in plain language. The Ofgem complaints data, while less granular on the non-domestic side, points the same direction as the domestic figures. The Energy Ombudsman route remains available for microbusiness disputes once the supplier's internal process has run. None of these features are unique to Octopus on paper; the combination, with the rate card in public view, is closer to unique in May 2026.
For an industrial-and-commercial-scale site wanting bespoke flex, a CPPA, or active wholesale risk management, the Octopus standard offer is not the right shape and a specialist desk is the better starting point.
The single most useful test for any SME considering Octopus in 2026 is direct comparison: pull the Octopus published rate for the relevant DNO region and meter profile, and put it next to any broker quote for the same period. If the broker quote is materially above Octopus direct after accounting for the broker's commission disclosure, the answer becomes obvious. Here is where it breaks for opacity: once the published rate exists, the broker has to justify the gap.

Frequently asked questions
Does Octopus Energy for Business cover gas as well as electricity?
Yes. The non-domestic offer covers both fuels, with separate principal terms for each. Microbusiness thresholds differ between fuels (100,000 kWh electricity, 293,000 kWh gas), so a single site can be microbusiness for one fuel and not the other.
Is there an early termination charge on a business fixed contract?
Yes. Like the broader non-domestic market, fixed business contracts at Octopus include an early termination clause that exposes the customer to the difference between the contracted price and the current market price for the remaining term. The principal terms document sets this out in writing.
Can a microbusiness still end up on out-of-contract rates with Octopus?
Yes, if no action is taken before the fixed term ends. The 2022 Ofgem rule banning automatic rollover into a new fixed term does not prevent the meter rolling onto deemed or out-of-contract rates, which are typically materially higher than a freshly negotiated fixed deal.
Is the Energy Ombudsman available for non-domestic disputes?
Automatic Ombudsman access applies to microbusiness customers under Ofgem rules. Larger non-microbusiness SMEs do not have the same automatic right, which makes the contract terms and supplier complaint procedure proportionally more important at the larger end.
How does Octopus's complaints record compare to other suppliers?
In Ofgem's quarterly complaint data, Octopus has consistently sat in the lower complaints-per-100,000-customer range on the domestic side. Non-domestic figures are reported with less granularity, but service infrastructure is shared between the two.
