The Smart Export Guarantee (SEG) is a UK government scheme that requires every licensed electricity supplier with over 150,000 customers to pay solar PV owners for surplus electricity they export to the grid. Octopus Outgoing Fixed (12p/kWh) is the highest widely-available flat rate; E.ON Next Premium v3 (17.5p) currently tops the table for E.ON import customers. The lowest rate (3p) earns 5× less than the best — so choose carefully. A typical 4kW solar install in the North East exports 2,000-2,600 kWh/yr, worth £300-£455/yr at the best rate.

Real earnings
Modelled for North East solar yield (950 kWh/kWp/year), typical UK household demand profile, and current tariff rates.
Earnings are modelled estimates and depend on your actual generation, household usage, weather, and rate changes. A larger battery typically reduces export (more self-consumption) — so the tariff choice matters most for non-battery and partial-battery setups.
Scheme comparison
The Feed-in Tariff (FiT) ran from April 2010 until it closed to new applicants on 31 March 2019. FiT paid two amounts per kWh: a generation tariff for every unit produced (regardless of where it went) plus an export tariff for units sent to the grid. Rates were set centrally by Ofgem, locked in for 20 years and index-linked to RPI — meaning a 2011 install on early FiT can still earn 60p+/kWh today.
The Smart Export Guarantee (SEG) launched on 1 January 2020 and works differently in four key ways. First, SEG pays for export only — there is no generation payment. Second, rates are set by each licensed supplier (not Ofgem) and can change with 30-day notice. Third, there is no fixed contract term, so you can switch tariffs whenever a better rate appears. Fourth, SEG requires a SMETS2 smart meter to measure half-hourly export; FiT relied on a separate generation meter and an export estimate based on a flat 50% assumption.
If you installed solar before April 2019 and are still on FiT, do not switch — your locked, index-linked rate is almost certainly higher than any current SEG offer. If you are installing today, SEG is your only option, and choosing the right tariff matters far more than it did under FiT because the supplier rate spread is now 3p to 17.5p (a 5.8× difference).
Battery exports
Most SEG tariffs pay on all metered export — the SMETS2 meter cannot tell whether each exported kWh came from your panels or your battery, so suppliers simply pay whatever flows out of the property. Octopus Outgoing Fixed, Octopus Outgoing Agile, E.ON Next Premium v3, British Gas Export & Earn Plus, EDF Export Variable Value and Scottish Power SmartGen+ all pay on solar and battery export equally. This makes time-of-use arbitrage possible: charge the battery off-peak (Octopus Go at 8.5p), discharge to the grid at the Agile peak (often 25-30p), and bank the spread.
Good Energy Solar Savings Export is the notable exception — it pays on solar generation only, verified against your inverter data. Battery export is excluded from its calculation. Good Energy customers who add a battery typically see their SEG payment fall slightly, because more of their solar is now self-consumed rather than exported.
If you plan to add a battery within the next 12 months, choose a supplier that pays on all export from day one — switching tariffs later costs nothing but the SEG application paperwork takes 8-10 weeks to clear, and you do not want a payment gap.

Anonymised case studies
5.4 kWp solar (in-roof, south-facing), no battery. First full year on Octopus Outgoing Fixed at 12p paid £412.20 across four quarterly credits — 2,748 kWh exported. Self-consumption sat at 34% because both adults are out at work during the day. Customer is now adding a 10 kWh battery to lift self-consumption and shift more export into Agile peak windows.
7.2 kWp solar plus 13 kWh battery plus EV charger on Octopus Intelligent Go. Total annual export: 1,920 kWh (battery raises self-consumption to 71%). On Octopus Outgoing Fixed: £288/yr. After moving to Outgoing Agile and using the API to discharge 4-5 kWh into the 16:00-19:00 winter peak: £441/yr — a 53% uplift for the same panels.
3.6 kWp solar, no battery, daytime occupancy. Self-consumption is unusually high (52%) because the customers run the dishwasher, washing machine and immersion heater during sunny hours. Annual export: 1,640 kWh. On Octopus Outgoing Fixed (12p): £246/yr. Had they stayed on E.ON Next legacy export (3p) they would have earned just £49.20/yr — a £196.80 annual loss for not switching.
Step by step
SEG eligibility starts with an eligible solar PV installation by a certified installer. All AMP Renewables solar installs come with your eligible installation certificate handed to you on commissioning day. You cannot apply for SEG without one.
We submit the G98 notification to Northern Powergrid before commissioning (or G99 if your system is over 3.68 kWp single-phase). You receive a printed copy of the DNO confirmation in your handover pack.
Without a smart meter the supplier can't read your export. If you don't have one, call your import supplier and request a SMETS2 fitting — it's free. Most installs happen within 2-4 weeks.
Use the comparison table above. For most North East customers, Octopus Outgoing Fixed is the best baseline. Battery owners with API capability can earn more on Octopus Outgoing Agile.
Each supplier has an online SEG application form. You'll need: MPAN (top of any electricity bill, 13 digits), install certificate number, install date, kWp rated capacity. Upload the install certificate PDF and DNO confirmation we provided.
Most suppliers pay quarterly by direct deposit. First payment typically arrives 2-3 months after sign-up (they need to receive at least one full quarter of meter readings). Octopus pays monthly via account credit which you can withdraw or roll forward against import bills.
Done-for-you
On commissioning day — typically 4-6 weeks after we sign your install contract — our engineer hands you a printed and digital SEG application pack. Inside is your installation certificate (signed by the certified installer responsible for the build), your Northern Powergrid DNO confirmation (G98 for systems up to 3.68 kWp single-phase, G99 for larger), your MPAN copied from the most recent electricity bill, the inverter and panel datasheets matching exactly what was installed, and a one-page tariff recommendation showing which SEG supplier is currently paying you the most given your import tariff and household profile.
We then walk you through the supplier application by phone — the form takes 10 minutes if you have the pack to hand. We have shepherded over 400 SEG applications across the North East since the scheme opened and we know the quirks of each supplier portal: where the MPAN field validates incorrectly, which suppliers ask for the kWp DC rating versus the AC inverter rating, and which need a separate battery declaration upload. Most customers receive their first SEG payment within 8-10 weeks of commissioning — well inside the 12-week window suppliers quote.
Every AMP Renewables solar install includes the SEG application pack on commissioning day — install certificate, DNO confirmation, MPAN, tariff recommendation, sign-up URL.
