What is the SEG?

The Smart Export Guarantee (SEG) is a government-supported program that enables you to sell your surplus energy back to the national grid. With this initiative, you can earn money by exporting energy you produce from renewable sources such as solar panels, wind turbines, or hydroelectric generators.

What do you need to apply for the Smart Export Guarantee?

Each supplier has different application requirements, but there are a few documents you usually need to send through, or extract information from:

  • MCS certificate, which will include your installation details, smart meter details and site details
  • A copy of your final bill marked as “paid”
  • Site schematic/single line connection diagram
  • G98/G99 post commissioning District Network Operator (DNO) notification form
  • G98/G99 DNO response

Your MCS certificate number can be found at the top of the second page of your MCS document and will start with 'MCS' as pictured below:



For all installations done through MakeMyHouseGreen you should expect to receive these documents within 14 days of your installation, we use technology to ensure these documents are with you as soon as possible. However, the G98/G99 DNO response may take up to three months as we depend on the DNO getting back to us.

If you've had your installation done with us, you will be notified once we have these documents ready for you, and you should be able to always access them by logging into your Make My House Green account, and clicking on My Installs, Install Documents.
