E.ON export tariff 2026 — 17.5p Premium, and the catch that drops most businesses to ~5.5p.

E.ON Next export tariffs 2026 — full rate table

E.ON Next runs a laddered export lineup in 2026, and the headline number everyone quotes — 17.5p/kWh — is the top rung, not the rate most businesses receive. The 17.5p Next Export Premium v3 is gated behind two conditions at once, and there is a long drop to the fallback Flex and Business rates near 5.5p. As an independent commercial-solar funding specialist we take no installer commission and sell no tariffs, so we can lay the whole ladder out plainly — E.ON’s own marketing leads with the 17.5p and rarely spells out the catch.

Indicative 2026 rates, structured to mirror E.ON Next’s own published export products (verified July 2026). SEG rates reset periodically — confirm the current figure with E.ON before signing. The 17.5p Premium and Exclusive tiers are gated to E.ON-installed systems on E.ON import; the Flex and Business products are the fallback rates non-eligible sites receive.

Do you qualify for E.ON’s 17.5p export tariff?

This is the question E.ON’s own page never answers head-on, and it decides everything. To get the 17.5p Next Export Premium v3 you must satisfy all three of the following at the same time:

• You are an E.ON Next electricity (import) customer — the export premium is bundled to keep your import business.
• Your solar was installed by E.ON (for the Premium and Exclusive tiers) — a third-party-installed array does not qualify, however you switch.
• You accept a 24-month fixed lock-in on E.ON import — leave the import deal and the 17.5p export rate goes with it.

The independent payoff: a business that bought its panels from another installer, or that wants to keep its existing import supplier, is not getting 17.5p — it lands on the Next Flex Export or Next Export Business rate near 5.5p. If that’s you, the right move is not to chase E.ON’s headline but to take the best open export rate: EDF at 12p kept on your own import, or a full Octopus switch — whose Outgoing Fixed rate is also 12p since the 1 March 2026 cut, so the switch only pays for itself through cheaper Octopus import or a dynamic Agile/Flux tariff with storage. We model your real eligibility before recommending either.

E.ON export tariff vs the rest of the market (2026 rates)

The column that matters for a commercial operator is “SEG-only available?” — most top payers, E.ON included, lock you into their import supply, while EDF will pay 12p with no import change at all. Here E.ON’s gated 17.5p headline and its ~5.5p fallback sit in-line, so you can see exactly where both land against the field.

Indicative 2026 rates for comparison, verified July 2026; confirm current figures with each supplier. Octopus Outgoing Fixed shows at 12p following its cut from 15p on 1 March 2026, which puts it level with EDF Export 12M Small Business and ScottishPower SmartGen+ on flat rates. See our full SEG comparison, EDF SEG, Octopus SEG and ScottishPower SmartGen+ pages for detail.

E.ON export tariff earnings by system size

Headline rates only matter once you put export volume against them. The table below shows indicative annual export income at each E.ON rate — the gated 17.5p Premium, the ~5.5p Flex fallback, and the best open rate available to a third-party-installed site — across system sizes from a domestic 4kWp up to a 250kWp commercial array. The gap between the Flex rate and the best open rate is the money a non-eligible business is leaving on the table every year.

Indicative figures. Export kWh assumes roughly half of generation is exported at typical UK commercial yields; sites with high daytime self-consumption export less, sites with quiet weekend load export more. Best open rate uses EDF Export 12M Small Business at 12p (SEG-only, no import switch) at every size, verified July 2026 — since Octopus cut Outgoing Fixed to 12p on 1 March 2026 the best open flat rate is 12p whatever the system size, and only a dynamic Octopus tariff with battery storage beats it.

What E.ON’s 17.5p costs you elsewhere — import lock-in maths

A headline export rate is only half the equation. The 17.5p Premium is welded to a 24-month E.ON import contract, so the right comparison is the net annual position — export earnings minus any premium you pay on import versus the cheapest deal you could otherwise hold. On a large supply, an uncompetitive import contract can quietly erase several thousand pounds of the headline export gain. The table models a 250kWp site exporting 120,000 kWh/year three ways:

Indicative modelling, rates verified July 2026. The point is directional: E.ON’s 17.5p can still win if you qualify and the paired E.ON import deal is genuinely competitive — but tied to a pricey import contract it can net out below a 12p Octopus bundle on cheap Octopus import, or below an EDF 12p SEG-only contract that leaves your existing import untouched. Because Octopus cut Outgoing Fixed from 15p to 12p on 1 March 2026, those two open routes now produce the same export earnings, which makes the EDF option the cleaner of the pair. We model export and import together, not the export headline alone.

How to apply for an E.ON export tariff (and switch away if you don’t qualify)

As independent funding specialists this is the part we handle for clients. E.ON requires six documents up front, and the application stalls in predictable places — but if you don’t qualify for the 17.5p tier, the smarter route is to skip E.ON’s export product entirely and take an SEG-only contract elsewhere.

1. Confirm which tier you qualify for — 17.5p needs E.ON import plus an E.ON-installed array. A third-party array or a desire to keep your own import drops you to the ~5.5p Flex/Business rate, so plan to switch export instead.
2. Gather E.ON’s six required documents — MCS or Flexi-Orb certificate, proof of address, a smart-meter photo, a schematic diagram, DNO approval, and the G98 or G99 connection notification.
3. Submit the E.ON Next export application online — upload the certificate and meter evidence and select the Premium, Exclusive, Flex or Business product you qualify for.
4. E.ON verifies eligibility — it checks the MCS certificate, the smart export meter and the DNO/G99 approval against the tier you applied for before activating the rate.
5. If you don’t qualify for 17.5p, take the SEG-only escape route — sign with EDF at 12p (keep your existing import, no exit fees, ~14 days) or switch fully to Octopus, whose Outgoing Fixed rate is also 12p since 1 March 2026. Both beat the E.ON Flex/Business rate of about 5.5p, and only the EDF route leaves your import contract alone.

Tax & VAT footnote for businesses: SEG export income is taxable for a company or sole trader and should be declared — there is no domestic-style exemption. For a VAT-registered business the export receipts may fall within the scope of VAT depending on your registration and the supplier’s arrangements, while the solar install itself can attract 0% VAT and the capital cost is usually relievable through capital allowances (AIA or the Annual Investment Allowance). The capital-allowance relief on the system typically outweighs the tax on the modest export receipts — confirm the detail for your structure with your accountant.

What the E.ON Next SEG tariff actually pays

The rate the typical commercial site actually receives from E.ON Next is the Next Flex Export / Next Export Business rate of roughly 5.5p/kWh — the fallback tier, not the 17.5p Premium headline. The 17.5p Next Export Premium v3 only applies to E.ON-installed systems on E.ON import (see the eligibility section above); every business that bought its array elsewhere, or keeps its own import supplier, lands at ~5.5p. That fallback rate clears the Smart Export Guarantee floor — suppliers with 150,000-plus customers must offer a rate above 0p — but it is a minimal compliance offer, not a competitive product. For context, 5.5p is less than half what EDF, Scottish Power and Octopus pay, so a non-eligible site is far better off taking the best open export rate than sitting on the E.ON Flex/Business rate.

Where E.ON Next’s fallback rate sits in the market

E.ON Next’s Flex/Business fallback (~5.5p) sits in the low band alongside OVO (5p), Shell Energy (3.5p) and British Gas Export & Earn Plus (6.4p). The high band is occupied by Octopus Outgoing Fixed (12p, cut from 15p on 1 March 2026), Octopus Outgoing Agile (14-18p average, requires Octopus import), EDF Export 12M Small Business (12p flat) and Scottish Power SmartGen+ (~12p) — so the top flat rates now sit level at around 12p, and the genuinely higher returns come from the dynamic tariffs. E.ON’s own 17.5p Premium tops that band — but only for the gated, E.ON-installed minority. The structural difference for everyone else: EDF can be signed as a SEG-only contract on top of any import supplier, while the rest require you to switch import too.

The honest fix: switch your export, keep your import

This is the part most E.ON customers miss. You do not have to leave E.ON entirely to escape the 5.5p export rate. EDF accepts SEG-only export contracts from customers on any other import supplier — so you can keep E.ON for import and move just the export contract to EDF at 12p. Switching only the export contract takes about 14 days, carries no exit fees, and does not touch your supply or your import deal. For a commercial operator part-way through a fixed-term E.ON import contract, this is the lowest-friction route to more than doubling export revenue.

• EDF Export 12M Small Business (12p) — SEG-only, no import switch, no exit fees, ~14-day move
• Octopus Outgoing Fixed (12p) — level with EDF since the 1 March 2026 cut from 15p, and still requires switching import to Octopus
• Octopus Outgoing Agile / Intelligent Flux (dynamic, peaks near 30p) — the highest-paying option overall, but only for sites with battery storage that can shift export into the evening peak
• Scottish Power SmartGen+ (~12p) — competitive, but requires Scottish Power import

E.ON Next SEG worked example — the revenue uplift

For a typical 500kWp commercial site exporting 120,000 kWh/year, currently on E.ON Next at 5.5p:

• Current E.ON Next SEG revenue at 5.5p: £6,600/year
• EDF Export 12M Small Business at 12p (SEG-only, keep E.ON import): £14,400/year
• Octopus Outgoing Fixed at 12p (full switch, rate cut from 15p on 1 March 2026): £14,400/year
• Uplift switching export to EDF: £7,800/year
• Uplift switching fully to Octopus: £7,800/year — identical, because both flat rates are now 12p
• 25-year cumulative differential vs EDF (CPI-adjusted): £220,000+
• Switching effort (EDF route): 14 days, no exit fees, import unchanged

The EDF route is the default recommendation because it captures the whole uplift with none of the import-contract risk. Since Octopus cut Outgoing Fixed to 12p on 1 March 2026 the two flat rates are identical, so a full Octopus switch adds nothing on rate alone — it only wins net if Octopus import pricing beats your current deal, or if you have battery storage and can run a dynamic Octopus tariff (Agile or Intelligent Flux, peaks near 30p), where the returns are genuinely higher. Otherwise a better export rate can be eaten by a more expensive import bill.

When does staying on E.ON Next make sense?

Rarely, for a commercial site. The one scenario where E.ON export is defensible is a site that self-consumes nearly all of its generation and exports almost nothing — in which case the export rate barely matters and the convenience of a single supplier wins. But any site with meaningful export volumes (a large roof, a quiet weekend load, or summer over-generation) is losing material revenue every year the export sits at 5.5p. The break-even is low: even modest export volumes justify the 14-day switch to EDF.

How to move off the E.ON Next SEG rate

1. Confirm you hold an MCS certificate in your business name for a sub-5MW system
2. Confirm your meter supports half-hourly export readings (most modern commercial meters do)
3. Decide the route: EDF SEG-only (keep E.ON import) or full switch to Octopus
4. For EDF: apply via the EDF SEG portal with your MCS number and meter point reference — no import change required
5. EDF verifies the certificate (5-10 working days) and the new export tariff goes live the next billing cycle
6. Cancel the E.ON Next export arrangement once the new contract is confirmed live

For SEG-only switches the whole process runs around 10-14 days end to end. Your E.ON import contract is untouched throughout, so there is no supply interruption and no exit fee exposure.
