Good Energy export tariff — 25p/kWh flat SEG, August 2026

Q: Do I need a battery to get Good Energy's 25p rate?

Yes. Solar Savings Exclusive requires solar and a battery installed by Good Energy Solar, JPS, Amelio or Empower. Other high headline rates (the now-closed Intelligent Octopus Flux and standard Octopus Flux) also require a battery.

Q: Is Good Energy's import tariff expensive?

The cheapest fixed deals on our live panel are typically priced below the £1,663 cap — compare by postcode for today's prices. For a high-export home, the estimated +£480/yr uplift versus a legacy 5p SEG usually outweighs the import-price gap, but you should check both sides.

It requires a battery installed by Good Energy Solar, JPS, Amelio or Empower — but then it’s one rate, all day, every day.

What 25p/kWh is actually worth

Estimated annual export income for a typical 4kW system exporting roughly 2,400 kWh/yr (about half of ~4,800 kWh generation, with the rest used in the home). Figures vary with system size and how much you self-consume — rates change, so treat these as estimates.

Good Energy export tariff — FAQs

Do I need a battery to get Good Energy’s 25p rate?

Yes. Solar Savings Exclusive requires solar panels AND a battery installed by Good Energy Solar, JPS, Amelio or Empower — that is the catch. Other high headline rates (the now-closed Intelligent Octopus Flux, which paid up to 32.17p/kWh, and standard Octopus Flux) also require a battery.

Do I have to switch my electricity supply to Good Energy?

Yes. The 25p rate is exclusive to Good Energy import customers. SEG normally lets your import and export sit with different suppliers, but bundled tariffs like this one are the exception — so weigh the import price against the export gain before switching.

I have a battery — is Octopus Flux better than Good Energy?

Usually, yes. A battery shifts your export into the evening peak where Octopus’s Flux tariffs can pay peak-time export rates — potentially beating a flat 25p once you account for the stored units you can sell at peak.

How is the export payment made, and is it taxed?

Your smart meter records export half-hourly and Good Energy credits each kWh at 25p against your bill — import and export in one place. SEG income is generally income-tax-exempt for owner-occupiers exporting from their own home.

Is Good Energy’s import tariff expensive?

Will the Ofgem price cap rise affect my export rate?

No — SEG export rates are not price-cap regulated, so the 25p rate is unaffected. The cap covers import prices and rose to £1,663/yr typical, which makes every kWh you sell at 25p more valuable against a higher import bill.

How long does it take to switch and start earning 25p?

Registration for Solar Savings Exclusive typically takes 5–10 working days once Good Energy has your MCS number, MPAN and export reading. The import switch runs on the standard timetable, so a switch started now can be earning 25p well before most homes feel the full effect of the higher current cap.

Lock in 25p/kWh under the current price cap

The Ofgem price cap is £1,663/yr typical. You cannot control the cap, but you can control what your panels earn: a legacy 5p SEG home is leaving an estimated £480/yr behind versus 25p flat, verified August 2026. Registration takes 5–10 working days — a switch started now beats the cap change. Want a full solar or battery install to lift your export further?
