If you have installed or are considering solar panels for your property, maximizing your return on investment extends beyond self-consuming your clean energy. The Smart Export Guarantee (SEG)—the UK government-backed scheme introduced to replace the Feed-in Tariff—requires licensed energy suppliers to pay micro-generators for excess renewable electricity exported back to the National Grid.

Because SEG rates are set independently by energy companies rather than fixed by the government, payout rates vary significantly across the market—from lower baseline rates to premium time-of-use tariffs. Navigating these options effectively ensures you earn maximum income from your generation.

Smart Export Guarantee Rates Compared

SEG tariffs generally fall into three primary categories: Flat Export Tariffs, Variable / Time-of-Use Export Tariffs, and Installer-Exclusive Premium Deals.

1. Standard Flat-Rate Tariffs

Flat-rate tariffs pay a consistent rate per kilowatt-hour (kWh) exported, regardless of the time of day.

• EDF Export 12m: Pays 15p/kWh for independent installs, provided you switch your import supply to EDF.
• Octopus Outgoing Fixed / E.ON Next / British Gas / OVO: standard bundled export tariffs pay around 12p/kWh to customers who also take their import electricity.
• Standalone Tariffs (No Import Switch): Suppliers who buy your export without requiring your import supply pay significantly less—typically 3p to 6p/kWh.

2. Time-of-Use & Smart Variable Tariffs

For households with solar battery storage, dynamic time-of-use export tariffs offer substantially higher yields.

• Octopus Flux: Offers peak export rates up to 24p–30p/kWh during high-demand evening hours (16:00–19:00) alongside reduced overnight import rates.
• Octopus Agile Outgoing: Tracks half-hourly wholesale electricity prices. Rates rise during national peak hours, delivering lucrative returns when managed with intelligent automated storage software.

How to Qualify for the Best SEG Rates

To secure high-paying SEG export rates, your renewable installation must meet specific industry requirements:

• MCS Certification: You must possess an official Microgeneration Certification Scheme (MCS) certificate. This validates that your system was installed to recognized industry standards using approved hardware.
• Smart Metering: An export-capable smart meter (such as a SMETS2 meter) configured to transmit half-hourly export readings is mandatory.
• Dual-Supply Alignment: Most premium tariffs paying 12p/kWh or higher require you to source both your import and export electricity from the same provider.

Why Self-Consumption Outperforms Exporting

While optimizing your SEG tariff improves annual returns, prioritizing self-consumption remains the most effective financial strategy. With grid electricity import prices hovering around 26p/kWh under standard tariffs, consuming a unit of energy you generate saves roughly 26p, compared to earning 12p to 15p by exporting it. Adding battery storage allows you to capture daytime solar energy, power your home after dark, and export only surplus energy during peak payout windows.
