The Smart Export Guarantee (SEG)

The SEG is a government-backed initiative that requires UK energy suppliers to pay you for the surplus renewable electricity your solar panels export back to the National Grid.

What You Need Before You Apply

Before starting your application, you must have the following documents and requirements in place:

An MCS Certificate: Proves your solar installation meets UK standards. Your installer should provide this to you upon commissioning.
A DNO Notification: Confirmation that your Distribution Network Operator (the company managing the power lines in your region) was notified of and approved your system. This is usually a G98 form for standard domestic systems, or a G99 for larger setups.
A Smart Meter: You must have a meter capable of taking half-hourly export readings.
Proof of Address: A standard utility requirement (such as a council tax or bank statement).

The Application Process

1.Choose your SEG supplier:

You do not have to use your current import energy supplier for your SEG tariff. Shop around, as rates vary significantly—from standard rates of around 3p per kWh up to 20p or more. Keep in mind that many suppliers offer their highest "exclusive" rates only if you also buy your import electricity from them.

2.Submit your application online:

Go to your chosen supplier's SEG portal. You will need to upload your MCS certificate, your DNO notification, and provide your MPAN (Meter Point Administration Number), which you can easily find on your electricity bill.

3.Wait for your Export MPAN to be created:

If this is your first time exporting, the supplier will apply to your DNO to create an "Export MPAN". This is typically the longest part of the process and can take a few weeks, as it entirely depends on the DNO's workload.

4.Provide an initial meter reading:

Once the MPAN is generated, your supplier will ask for an initial export meter reading (often requesting a photo of the meter screen) to ensure the account is set up correctly.

5.Receive your payments:

The supplier will verify your readings and activate your account. Payments are typically credited to your account quarterly or annually, depending on the supplier's terms.
