Solar export rates vary widely. Mr Solar helps you compare current Smart Export Guarantee options and design a solar-and-battery system around the way your home actually uses energy.
Compare SEG rates
Rates are ranked by their highest advertised export price. This comparison excludes tariffs that require the solar or battery system to have been fitted by the energy supplier.
| Supplier & tariff | Export rate | Who can apply? | Example at 2,000 kWh | Check supplier |
|---|---|---|---|---|
Octopus Energy Prime Outgoing Octopus | 16p peak 4–7pm; 9p at other times | Octopus import customer Solar + battery recommended | Depends on export timing | Official rate ↗ |
EDF Export 12m | 15p/kWh | Supply-linked Existing EDF electricity customers | £300/year | Official rate ↗ |
E.ON Next Next Export Exclusive v3 | 13p/kWh | Supply-linked E.ON import tariff, excluding time-of-use | £260/year | Official rate ↗ |
Good Energy Solar Savings | 12p/kWh | Supply-linked Good Energy electricity customers | £240/year | Official rate ↗ |
British Gas Solar Export Tariff | Up to 12p/kWh | Supply-linked Best rate for British Gas electricity customers | Up to £240/year | Official rate ↗ |

OVO SEG Beyond Exclusive | 12p/kWh | Supply-linked OVO energy; technology installed elsewhere | £240/year | Official rate ↗ |
Important: snapshot checked 10 August 2026. Installer-exclusive rates have been excluded. Some tariffs still require the supplier to provide your imported electricity. Rates and eligibility can change. Example earnings are rate × 2,000 kWh exported and are not a prediction or guarantee. They exclude electricity-bill savings, import costs, standing charges, equipment costs and degradation. Always confirm the live tariff and full terms with the supplier.
How Mr Solar helps
Understand your home
We assess your roof, annual usage and when you typically use electricity.
Right-size the system
Panels, battery capacity and EV charging are designed around real needs—not a one-size package.
Compare tariff fit
We explain fixed, time-of-use and supplier-linked options without promising a particular return.
Install and support
We support the DNO process, SEG paperwork and ongoing system monitoring.
Export income is only one part of the picture.
If you export 2,000 kWh in a year, a flat 12p tariff would pay £240. At 15p it would pay £300. Your total benefit may also include electricity you generate and use at home, but it must be assessed separately.
Your home. Your habits. Your tariff.
System size, roof orientation, shading, weather, electricity use, battery settings, export limits, import prices and tariff eligibility all affect the outcome. That is why Mr Solar provides a personalised projection before you decide.
Talk to an expertSEG FAQ
What is the Smart Export Guarantee?
SEG is a UK arrangement under which participating licensed electricity suppliers pay eligible small-scale generators for metered electricity exported to the grid. Each supplier sets its own rates and eligibility rules.
Do I need a battery?
No. A solar-only system can export surplus electricity. A battery may let you store energy for use later or, on a compatible time-of-use tariff, shift exports to a higher-value period.
Is the highest rate always the best tariff?
Not necessarily. Some rates require the supplier to provide your imported electricity or need a compatible battery and smart meter. Import rates and the amount and timing of your exports also matter.
Are savings or export earnings guaranteed?
No. Any projection depends on the property, system, household use, weather, export behaviour and future tariff rates. We will explain the assumptions used in a personalised estimate.
What do I normally need to apply?
Requirements vary, but commonly include an eligible certified installation, a compatible smart/export meter, an export MPAN, proof of ownership and relevant commissioning or MCS documentation.
