What is the Smart Export Guarantee (SEG)?

Smart Export Guarantee

The Smart Export Guarantee (SEG) is a UK government-backed scheme that allows solar panel owners to earn money by selling surplus solar power back to the grid. Electricity suppliers pay for each unit of exported power, turning solar installations into profitable investments.

How does the SEG work?

  • Solar panel owners generate electricity from their panels.
  • Any excess electricity that is not used in the home is sent back to the grid.
  • Electricity suppliers then purchase this exported electricity from solar panel owners.
  • The rates per kilowatt-hour (kWh) of exported electricity are set by each supplier, creating a competitive market.

How can you find the best SEG tariff?

To help consumers navigate this landscape, Solar Energy UK publishes a league table ranking suppliers based on their SEG rates, as shown below. This resource can guide your decision-making process by showing you which suppliers offer the best tariffs for exported electricity.

This understanding of the SEG scheme positions solar panel owners favourably in the energy market. By selecting the right supplier and tariff, you can maximise your earnings from solar power generation.

Eligibility Criteria for SEG Participation

To participate in the Smart Export Guarantee (SEG) program, you need to meet certain criteria and have the necessary technical setup. Here's what you need:

Valid MCS Certificate


The most important requirement is having a valid MCS certificate for your solar panel installation. This certificate is proof that your system meets the standards set by the Microgeneration Certification Scheme (MCS).

📝 MCS Certificate: It's a mark of quality that ensures both your solar panels and their installation meet specific standards. Having an MCS certificate is essential for SEG participation as it guarantees that your system is installed correctly.

Ownership of an Export Meter and an Export MPAN

You also need to have an export meter and an export MPAN:

  1. An export meter measures the amount of electricity you send back to the grid from your solar panels. It's important to have an export meter to get accurate readings of your exported power.
  2. The Meter Point Administration Number (MPAN) is a unique identifier for your electricity supply point. Your energy supplier uses this number to properly allocate the electricity you've exported.

Role of Smart Meters in SEG

Smart meters are recommended for SEG participants because they provide precise measurements of exported electricity in half-hour intervals. Energy suppliers may even require you to have a smart meter installed:

🌱 Role of Smart Meters: These advanced devices ensure accurate tariff rates by recording your energy generation and export data every 30 minutes. They help future-proof against potential mandatory smart meter usage.

By meeting these eligibility criteria and technical requirements, you can ensure that you're ready to take full advantage of the SEG program and maximise your earnings from solar power generation.


Harness the power of the sun, and let it work for you. With the best Smart Export Guarantee tariffs in 2024, you can transform your solar panels into a revenue stream. Let's recap on what we've learned:

  1. Octopus Energy leads the charge with competitive rates up to 24p/kWh for their customers.
  2. OVO Energy and E.ON Next follow closely behind, offering attractive rates.
  3. Shell Energy and British Gas provide additional options, each with their unique rate structures.

Remember, every penny counts when it comes to maximising your earnings from solar panels. These suppliers with the best SEG tariff rates on the market offer enticing opportunities that should not be overlooked.

However, choosing an energy supplier is no light task. It requires careful consideration of rate structures, requirements, and long-term benefits.

Smart Export Guarantee FAQ

What is the smart export guarantee?

The Smart Export Guarantee (SEG) is a financial incentive for owners of small-scale, low-carbon electricity generators. It allows them to earn money by selling excess electricity back to the National Grid. To qualify for these payments from electricity suppliers, specific requirements must be fulfilled.

Key Points of the SEG:

Eligibility: Owners of small-scale renewable energy installations.

Benefit: Receive payments for surplus electricity exported to the grid.

Criteria: Must meet certain standards and regulations.

The SEG is designed to support the growth of renewable energy in the UK, making it a win-win for both green energy producers and the environment.

Is the smart export guarantee worth it?

Octopus Energy's tariff is nearly on par with what consumers typically pay for electricity, making it an attractive option for those looking to maximize their returns from surplus energy exported to the National Grid.

For non-Octopus customers, Scottish Power offers a notable alternative at 12p per kWh.

While this doesn't match Octopus's rate, it's significantly higher than the last Feed-in Tariff's export rate of 3.8p per kWh, which ceased in 2019.

The SEG enables companies to purchase electricity from private generators at rates that are, on average, less than half of what they charge consumers. In some cases, the disparity can be as high as 96%, underscoring the importance of choosing the right tariff to ensure fair compensation for your exported energy.

Who pays the best SEG tariff?

Currently, Octopus Energy is leading the pack with the best Smart Export Guarantee (SEG) rates in the UK. They offer a flat rate of 4.1p per kWh for every unit of power you export to the grid under their SEG tariff. However, if you're an Octopus Energy customer, you can benefit from even better rates. Including up to 24p per kWh with Ocotopus Flux.

How much do I get paid for generating electricity?

How much can I sell my electricity for? The amount you'll be paid for selling solar power back to the National Grid through the Smart Export Guarantee will vary depending on the tariff you choose. It could be between 1p/kWh to 24p/kWh – the best rate available at the time of writing. Which is through the Octopus Flux tariff.

Do you pay tax on SEG payments?

Individual consumers typically do not have to pay income tax on SEG payments. These payments are considered a return on investment for the electricity they export back to the National Grid from their renewable energy installations, such as solar panels. As such, for most individual consumers, SEG payments are not taxed as income.

Businesses, on the other hand, must treat SEG payments as trading income. This means that these payments are subject to income tax or corporation tax, depending on the business structure. However, SEG payments are not subject to Value Added Tax (VAT). Additionally, businesses can offset SEG payments against other taxable income, which can reduce the overall tax liability.

Are SEG payments likely to increase?

The SEG tariffs have largely remained unchanged or have seen slight increases, reflecting a cautious approach by suppliers amidst the evolving energy market. This trend is underscored by the data from Ofgem's annual reports, which highlight the range of tariffs offered and the payments made to generators.

The reports reveal a growing number of installations and an increase in payments, indicating a positive trajectory for SEG participants.
