Did you know you can earn money for the unused energy your solar panels generate and export back to the grid? It’s called the Smart Export Guarantee (SEG).

What is the SEG?

The Smart Export Guarantee is a government-backed scheme where energy suppliers pay you for the electricity you export to the National Grid. Unlike older schemes, there’s no fixed rate, each energy company sets their own tariff. That means you can shop around for the best deal.

 Top tip: Start with your current energy supplier, they often offer better SEG rates to existing customers.

What Do You Need to Apply?

To set up SEG payments, you’ll need the following documents:

  • Your DNO (Distribution Network Operator) approval
  • Your MCS certificate (proves your system meets standards)
  • Proof of ownership, such as:
    • Invoice (if you paid privately)
    • Certificate of ownership (if installed through the ECO scheme)

Most suppliers allow you to apply online, quick and easy!

Common Application Questions We Get

If you’re filling out your SEG application and feel stuck, here are answers to some frequently asked questions:

  • Declared Net Capacity and Installed Capacity – Both can be found on your MCS certificate
