OVO offers three Smart Export Guarantee tariffs: a standard SEG rate of 4p per kWh open to any energy supplier’s customers, SEG Beyond Exclusive at 12p for OVO Energy customers, and SEG Install Exclusive at up to 20p if OVO installed your solar panels and battery. All three require MCS or equivalent certification.
The short answer
What is the OVO SEG tariff?
The Smart Export Guarantee replaced the Feed-in Tariff in January 2020, and every large energy supplier must offer at least one export tariff under it. No rate is set by government, so each SEG supplier decides what your exported renewable energy is worth.
OVO’s answer is three tiers, graded not by how much you generate but by how much of your business OVO has.
One practical difference appears only in OVO’s support pages. The standard tariff sends each export payment to your bank account; both exclusive tiers pay into your energy account. Not a trivial distinction — money in your bank is money, while account credit only has value against a bill you were going to pay anyway. Payments come every three months.
OVO SEG export rates (August 2026)
| OVO product | Export rate | Key condition |
|---|---|---|
| SEG | 4p/kWh | Up to 5 MW (50 kW micro-CHP); electricity supply with any provider; paid into your bank account |
| SEG Beyond Exclusive | 12p/kWh | Under 30 kW; electricity supply with OVO |
| SEG Install Exclusive (solar + battery) | up to 20p/kWh | Under 30 kW; supply with OVO; OVO installed your solar panels and home storage battery |
| SEG Install Exclusive (solar only) | 15p/kWh | As above, with solar panels installed by OVO but no battery storage |
Rates as published on OVO’s SEG page, checked 10 August 2026. OVO can revise these tariff rates — confirm before applying.
Notice the capacity limit dropping from 5 MW on the open tariff to 30 kW on both exclusives. Nobody here is near either number, but it tells you something: those two are a different product, sold to customers who let OVO install solar panels for them, not a loyalty discount on the standard one.
“Up to 20p” is doing real work, too. It means you bought solar and a battery from OVO. Panels without storage pay 15p.
Who is eligible for the OVO SEG tariff?
Before you sign up for SEG, OVO’s application form asks for:
- Renewable energy generation inside the capacity limit for your tier — 5 MW on the standard SEG, under 30 kW on both exclusives.
- An MCS-certified renewable energy system, or equivalent, in OVO’s own words.
- A smart meter to track the electricity you export. You need an export MPAN too, but OVO creates one if you do not have it, or switches yours across from your current SEG provider.
- A battery schematic diagram, where a battery is installed.
- You cannot be receiving FiT export payments or public grants.
- For both exclusive tiers: an OVO electricity supply.
Two of the three tiers, then, are gated on things with nothing to do with generating electricity: who bills you, and who installed the kit.
One thing OVO does notrequire, despite how the page reads at a glance. Both exclusive tiers carry the line “Plus, earn rewards when you link your account to Beyond” — Beyond being OVO’s free rewards account. That sits alongside the eligibility icons but it is a benefit, not a condition. The three conditions OVO actually lists for the 12p tier are generating at home, capacity under 30 kW, and taking your electricity supply from OVO.
The MCS barrier affects balcony solar owners
How OVO compares to Octopus and the rest
Every rate below was checked on the supplier’s own tariff page on 10 August 2026. We separate the rate you can take without moving your import supply from the best rate advertised, because those are rarely the same thing.
| Supplier | Best open rate (no import switch) | Highest rate available | Condition on the top rate |
|---|---|---|---|
| OVO | 4p — SEG | 20p — SEG Install Exclusive | OVO installed your panels and battery |
| ScottishPower | 6p — SmartGen | 15p — SmartGen Premium Plus | ScottishPower installed your panels or battery |
| E.ON Next | 6p — Next Flex Export v1 | 17.5p — Next Export Premium v3 | E.ON installed it after 10 November 2025 |
| British Gas | 3p — Export SEG | 12p — Export Premium | British Gas electricity customer, up to 15 kW |
| EDF | 3p — SEG Export Variable | 18p — Export Exclusive 12m V3 | Bought solar or a battery from EDF after 2 March 2026 |
| Octopus | None — Octopus supply required | 12p — Outgoing Octopus | Octopus import tariff |
All figures verified from each supplier’s own tariff page on 10 August 2026. These different export rates are variable or fixed-term, and the rates and terms can change.
Octopus footnote: the 12p above is the flat Outgoing Octopus rate. Octopus also publishes Prime Outgoing, paying 16p per kWh between 4pm and 7pm and 9p the rest of the day, and Agile Outgoing, which tracks half-hourly day-ahead wholesale prices and is uncapped. This table compares flat rates, so 12p is the like-for-like figure.
So, is OVO cheaper than Octopus? Wrong comparison. Both pay 12p on their supply-locked tier, and neither pays it without taking your import business first. What decides anything is the open rate, and there OVO’s 4p is mid-table — ahead of British Gas and EDF at 3p, behind ScottishPower and E.ON Next at 6p, and available where Octopus offers nothing at all.
Does OVO have the best SEG tariff, then? Its 20p is the highest headline number of the six. It is also only reachable if OVO sold and installed your system, making it part of an installation price rather than a SEG export tariff you can shop for. Our SEG export rates comparison for 2026 sets out the market, and our Octopus SEG tariff guide and Scottish Power SEG tariff guide cover the closest alternatives.
What this means for balcony solar specifically
Most people reading this cannot apply for a SEG tariff at all — not with OVO, and not with any of the other suppliers we checked. OVO wants an MCS-certified system or equivalent, and a plug-in kit you connected yourself is not one. Legalisation does not fix it. SI 2026 No. 848 makes compliant plug-in solar lawful to sell and use in Great Britain from 27 August 2026, but creates no MCS route.
Suppose it did. Would it be worth having?
Run the numbers behind our savings calculator. An 800 VA kit is the largest the Interim Product Specification permits, and from 27 August 2026 a household may connect one device. Facing south from a London balcony on an angled bracket, that generates roughly 577 kWh a year after the 0.78 performance ratio. About 60% is consumed on the spot, so around 231 kWh goes back to the grid.
You earn money only on that exported share. At OVO’s open 4p it is worth about £9.24 a year; at 12p, £27.72; even at 20p — which no plug-in owner can hold, because OVO did not install the kit — £46.20. Against a kit costing £400–£600, none of those numbers pays for anything.
The 346 kWh you use yourself is worth roughly £83at a 24p import price, and that is the actual return. It lands inside the government’s reported £70–£110 estimate for a plug-in kit.
Illustrative only: 800 VA south-facing, angled balcony mount, London irradiance, 60% self-consumption, 24p import. Your figures will differ.
At 4 kW on a roof, OVO’s ladder from 4p to 20p is a real financial decision worth hundreds a year. At 800 VA on a balcony it is not a decision at all. Put the effort into using what you generate — our self-consumption guide and smart tariffs guide are where the value sits.
Frequently Asked Questions
What is the OVO SEG rate?
Three rates. The standard tariff pays 4p per kWh, SEG Beyond Exclusive 12p, and SEG Install Exclusive up to 20p — falling to 15p where OVO installed solar panels without a battery. Checked on OVO’s own page on 10 August 2026; confirm the current figure before you apply for a SEG tariff.
Do I need to be an OVO customer to get a SEG tariff?
Only for the good rates. The 4p standard tariff is open whoever supplies your electricity. The 12p tier needs OVO to supply your home. The top tier needs that plus OVO having installed your solar panels and battery storage. Linking your account to OVO Beyond is promoted alongside both exclusive tiers, but OVO lists it as a reward rather than a condition.
Who is cheaper, OVO or Octopus Energy, for export?
Level where they are easy to compare, not comparable where it matters. Both pay 12p on their supply-locked tier, and both want your import business first. On the open rate the picture differs completely: OVO pays 4p to customers of other suppliers, while Octopus offers nothing unless you are an Octopus energy customer. See our SEG export rates comparison.
Can I get an OVO SEG tariff for balcony or plug-in solar?
Almost certainly not. OVO requires an MCS-certified renewable energy system or equivalent, and a plug-in kit you connect yourself is not certified and has no installer to certify it. Legalisation on 27 August 2026 makes compliant plug-in solar lawful in Great Britain but creates no certification route. For a kit this size the return comes from self-consumption anyway.
Do I need a smart meter for SEG?
Yes. OVO needs a smart meter and an export MPAN to measure what you export back to the grid, and asks for a battery schematic where a battery is fitted. That is standard across the scheme — without a meter that records export to the grid, there is no way to know what you sent.
