SEG - Smart Export Guarantee

The Smart Export Guarantee, often referred to as the SEG, is the tariff through which you can get paid for the electricity you export back to the grid. If your home or business generates renewable energy that you don’t use, you can claim the SEG.


The SEG is part of the government's aim to become a net-zero economy by 2050.


What is Exported Power?

Sometimes your Solar PV System will generate more power than you can consume within your home or business. For example, if your PV system is generating 2kWh’s of electricity, but you’re only consuming 1kWh within the property, the remaining 1kWh will be sent back to the grid to help make the grid greener. Your SEG Supplier will pay your for that electricity.


How does the SEG work?

Your total exported power is recorded by your Smart Meter. When your energy supplier pulls the information from your Smart Mater about how much electricity you’ve used during the month, they will also see how much you’ve exported.


Who can apply?

Any Solar PV generator, whether you’re a home or business, can apply for the SEG as long as they aren’t receiving any other incentive, such as the old Feed-In-Tariff payments and the system isn’t larger than 5MWp of capacity.


Who pays you?

You are free to sign up to any suppliers Smart Export Guarantee scheme. (If you’re viewing this information as a PDF, click here for a list of SEG suppliers). Some energy suppliers are mandated to provide an SEG payment if they have over 150,000 customers and are classed as a large supplier. Some smaller suppliers also voluntarily offer an SEG tariff. It does not have to be your existing energy supplier.


How much do you get paid?

The amount you get paid will vary, as some suppliers value the energy you export more so than others. You can view a list SEG payment rates here:


How long does it take to sign up?

Your supplier should be able to sign you up relatively quickly, all they need to do is confirm they’re receiving the figures correctly from your meter. You should normally expect to be signed up within a couple of weeks.


What will I need to claim the SEG?

You will need some specific paperwork to be able to claim the SEG that ensures your installation complies with the industry and grid regulations. You will likely be asked to produce the following:


  • MCS Certificate, or equivalent.

  • DNO Acceptance Letter – This confirms your Distribution Network Operator has accepted the connection of your installation to the grid. DNO acceptance is not to be confused with DNO notification. The DNO must formally accept that the installation has been completed and commissioned inline with their permitted connections guidance. Every GB Solar customer will have this provided to them following acceptance from your DNO. 

  • You will also require a SMETS II smart meter. If you do not have one, you will be able to apply to have one installed completely free-of-charge by your energy supplier.
