OVO SEG tariff — among the lowest UK rates, and the case for switching.

OVO SEG tariff rates 2026

OVO Energy runs a small family of SEG products rather than one rate, and all of them sit in the 4–5.5p/kWh band — among the lowest UK SEG rates in 2026. As an independent commercial-solar funding specialist we take no installer commission and run no energy-supply book, so we can name OVO’s actual variants and say plainly what OVO’s own product pages will not: for most commercial operators the OVO SEG rate is a reason to switch the export contract, not to stay. Indicative OVO SEG product rates for 2026:

Indicative 2026 rates — OVO does not publish a fixed premium SEG tier and its variants all cluster in the 4–5.5p band. Confirm the current rate with OVO before signing. Every OVO SEG variant requires OVO for import; none is available as a standalone SEG-only contract for non-OVO import customers.

OVO SEG vs every other UK supplier (2026 rates)

The column that decides a commercial operator’s choice is not just the export rate — it is whether the supplier forces an import switch, and which import tariff pairs best. OVO at ~5p pays roughly a third of Octopus and under half of EDF. The one genuinely switch-free high payer is EDF Export Standard at 12p, which you can sign while keeping OVO for import:

What does OVO pay for SEG in 2026?

In 2026 OVO pays approximately 5p/kWh (a 4–5.5p band across its product variants) on exported solar electricity, paid quarterly against your metered export. That places OVO in the bottom tier of the UK SEG market — above only Shell Energy (3.5p) and broadly level with E.ON Next (5.5p). For context, the leading SEG products pay 12–15p flat, so an OVO SEG customer typically earns under half what the same exported kWh would earn elsewhere.

Is the OVO SEG tariff worth it?

For most UK commercial solar operators, the OVO SEG tariff is not worth keeping as your export contract. At ~5p it pays roughly a third of Octopus Outgoing Fixed (15p) and under half of EDF Export Standard (12p). It only makes sense if you have a specific reason to consolidate import and export with OVO and your export volume is small. On any meaningful commercial export volume the differential runs into four or five figures a year, and switching the export contract is low-effort — so “worth it” almost always points to switching off OVO.

Can I switch off OVO SEG without changing my electricity supplier?

Yes. A SEG export contract is independent of who supplies your import electricity, so you can switch off OVO SEG and keep OVO — or any other supplier — for import. The highest-paying export contract you can sign without touching import is EDF Export Standard at 12p flat. The switch takes around 14 days, there are no exit fees on a standard OVO SEG agreement, and your import contract is untouched throughout. Step-by-step process below.

How does OVO SEG compare to Octopus and EDF?

OVO SEG (~5p) sits well below both: Octopus Outgoing Fixed pays 15p flat (with Agile averaging 14–18p and Flux peaks near 30p), and EDF Export Standard pays 12p flat. On a 500kWp site exporting 120,000 kWh/year that is £6,000 on OVO against £14,400 on EDF and £18,000 on Octopus — an £8,400–£12,000/year gap. Octopus pays most but requires an import switch; EDF is the best rate available without one, which makes it the usual landing spot for operators leaving OVO SEG.

OVO SEG product — basic flat rate

OVO Energy operates a basic SEG offer in 2026 paying 4-5.5p/kWh on exported solar electricity. The exact rate varies narrowly across OVO\'s product variants but stays in this band. OVO SEG requires OVO import — it\'s not available as a standalone SEG-only contract for non-import customers.

Payment cadence is quarterly. Application is via the OVO SEG portal; requires MCS certificate confirming the PV system is under 5MW and a smart meter capable of half-hourly export readings.

Where OVO SEG sits in the UK 2026 market

OVO at 4-5.5p sits in the bottom tier of UK commercial SEG products. The full UK 2026 commercial SEG market by tier:

Top tier (12-15p flat, 25-40p dynamic peaks)

• Octopus Outgoing Fixed — 15p flat (Octopus import required)
• Octopus Outgoing Agile — dynamic, average 14-18p, peaks 25-40p
• EDF Export Variable — 12-18p banded
• EDF Export Standard — 12p flat (SEG-only available)
• Scottish Power SmartGen+ — 12p flat (SP import required)

Middle tier (5-8p flat)

• British Gas Export & Earn Plus — 6.4p flat
• Good Energy Generation Tariff — 5-8p flat
• E.ON Next Export — 5.5p flat
• OVO SEG — 4-5.5p flat

Bottom tier (3-4p flat)

• Shell Energy Export — 3.5p flat

The economic case for switching off OVO SEG

For a typical UK commercial solar operator on OVO SEG, the case for switching the export contract is straightforward. Worked example for a 500kWp commercial site exporting 120,000 kWh/year:

• OVO SEG at 5p: 120,000 × 5p = £6,000/year
• EDF Export Standard at 12p (SEG-only switch, OVO import unchanged): 120,000 × 12p = £14,400/year — £8,400/year more
• Octopus Outgoing Fixed at 15p (requires import switch to Octopus): 120,000 × 15p = £18,000/year — £12,000/year more
• Octopus Outgoing Agile + battery (active management): ~£21,600/year — £15,600/year more

Over a 25-year system life, the differential between OVO SEG and Octopus Outgoing Fixed compounds to approximately £300,000 of cumulative revenue (CPI-adjusted). For most commercial operators, switching SEG is the single highest-impact post-installation optimisation available.

How to switch off OVO SEG without changing import

If you want to keep OVO import (e.g. you\'re mid-contract on a fixed-term deal), the highest-paying SEG-only switch is to EDF Export Standard at 12p flat. EDF accepts SEG-only contracts; OVO import unchanged.

If you\'re willing to switch import too, the highest-paying option is Octopus Outgoing Fixed at 15p flat (or Octopus Outgoing Agile for sites with battery storage). Switching both takes 14 days running in parallel.

Commercial export revenue by system size and supplier

Every domestic SEG guide quotes £900–£1,067/year figures. Commercial solar exports at a different order of magnitude, and that is exactly where staying on OVO SEG costs the most. The matrix below shows indicative annual export income by system size, assuming a typical commercial export fraction (~50% of generation exported), across OVO (~5p), EDF (12p), Octopus Outgoing Fixed (15p) and a well-managed Octopus Agile + battery setup (~18p effective):

Indicative figures, illustrative export fraction (~50% of generation, ~960 kWh/kWp annual yield); actual export depends on daytime self-consumption, orientation and shading. The point is directional, not a quote: on a 500kWp site the OVO-to-Octopus gap is ~£12,000/year, and on 1MWp ~£31,000/year — compounding to roughly £300,000–£775,000 over a 25-year system life.

OVO SEG eligibility & how to apply

The OVO SEG eligibility rules are the standard Ofgem SEG criteria — the same gate every UK supplier applies. Confirm these before you apply (whether to OVO or to a higher-paying supplier you switch to):

• MCS certification under 5MW — the PV system must be MCS (or equivalent ROO-FIT/Flexi-Orb) certified, in the business name, with installed capacity below 5MW.
• Half-hourly export meter — a smart or half-hourly-capable meter that records exported kWh (SEG pays on actual export, never a deemed estimate). OVO arranges an upgrade if yours can’t.
• DNO connection agreement — the install must have a valid G98 (small) or G99 (larger commercial) connection notification with your Distribution Network Operator.
• Not on the Feed-in Tariff — FiT and SEG are mutually exclusive for the same installation. Legacy FiT installs stay on FiT (usually more generous) and cannot also claim SEG.
• OVO import — OVO only accepts SEG from its own import customers; there is no standalone OVO SEG-only contract. (This is itself a reason switchers look at EDF, which accepts SEG-only.)

How to switch off OVO SEG — step by step

This is the part we handle for clients as independent funding specialists. The switch is online and keeps your import supply untouched:

1. Confirm your export contract is separable — check you’re on a standard OVO SEG agreement, not a bundled FiT or fixed-export deal with an exit fee. Standard SEG export contracts switch independently of import, penalty-free.
2. Gather your documents — MCS certificate in the business name (system under 5MW), your export MPAN from your electricity bill, and confirmation of a smart/half-hourly export meter.
3. Choose the right replacement export tariff — to keep your import supplier, move to EDF Export Standard at 12p (highest SEG-only rate, no import switch). To maximise the rate, switch import too and take Octopus Outgoing Fixed at 15p (or Agile with a battery).
4. Apply to the new SEG supplier — submit the online SEG application with your MCS certificate and export MPAN. They run an independent MCS and meter check; OVO import stays untouched.
5. New export contract goes live — the new tariff activates from the next billing cycle, typically within 14 days, paid against actual metered export. The OVO SEG export side lapses automatically when the new contract registers.

Battery & dynamic export — beating OVO’s flat 4-5.5p

OVO’s SEG is a flat rate: every exported kWh earns the same ~5p whether it leaves the meter at noon or during the 4–7pm evening peak. The biggest revenue upgrade for a commercial site is to pair battery storage with a dynamic export tariff — Octopus Outgoing Agile or Intelligent Octopus Flux — where evening-peak export can fetch 25–40p/kWh, five to eight times OVO’s flat rate.

Commercial battery-arbitrage worked example, 500kWp site with a 500kWh battery: instead of exporting midday generation at OVO’s flat 5p, the battery stores ~150 kWh/day of surplus and discharges it into the evening peak at ~30p. That single shift is worth roughly 150 kWh × 25p uplift × 300 trading days ≈ £11,000/year on top of the base export switch — before counting overnight import-charging arbitrage. The capital cost of the battery qualifies for Full Expensing (25% effective tax saving) and 0% VAT, and a PPA can fund the system with no upfront capex. Dynamic export only works with storage and active management, which is why it never appears in OVO’s flat-rate product — and why it is the single highest-value move off OVO SEG for a battery-equipped commercial site.
