The Smart Export Guarantee

What's the Smart Export Guarantee?

The Smart Export Guarantee (SEG) is a government-initiated export tariff for British businesses and homes who have installed small-scale, renewable or low carbon technology. It means that as a licensed electricity supplier, and a mandatory SEG licensee, we'll pay you for every kilowatt hour of unused, eligible electricity your business generates and feeds into the National Grid. It replaces the export part of the Feed-in-Tariff (FiT) scheme, which closed to new applicants in March 2019.

Do I qualify for the Smart Export Guarantee?

You'll be eligible for this tariff if:

  • You've installed renewable or low carbon technology in your business and
  • You have a smart meter, or a meter that can record export readings half-hourly.

What types of renewable or low carbon technology do I need?

You can apply if you have solar photovoltaic (PV), wind, hydro or anaerobic digestion (AD) up to a capacity of 5MW, or micro-combined heat and power (micro-CHP) up to a capacity of 50kW. Your installation must be accredited by the Microgeneration Certification Scheme (MCS)  or equivalent.

How the Smart Export Guarantee works

We'll pay you 3.2 pence for every kilowatt hour (kWh) of eligible electricity you export to the grid on our Export and Earn Flex tariff.

You'll need to provide an opening export meter reading when you start the contract, and then export meter readings every six months by email.  If you decide to leave, you'll need to provide a final export meter reading, so we can issue your final payment and settle your account.

We'll only make SEG Payments once in any six-month period. For example, if you provide your meter readings four months since your last read was paid, we’ll ask you to provide a read in two months' time.

Or if you were to provide your meter reading eight months since you were last paid by us, we’ll pay you for all the export earnings in that eight-month period. We would then expect the next meter reading from you six months later – but no sooner than that.

After receiving your meter reading, we'll send you a cheque, or a bank transfer if you have supplied us with your bank details, for that amount within 28 working days. We'll only make SEG Payments once in any six-month period.

Our minimum cheque for payments is £7, so if the payment due is less than that, we'll add it to your next six-month payment cycle.

Export and Earn Flex tariff

Our SEG export tariff is called Export and Earn Flex. It's a variable price tariff, which means the export rate could go up or down. There's no fixed end date and no exit fee, so you'll have the freedom and flexibility to switch to a new export tariff whenever you choose - with nothing to pay. You don't need to buy your electricity from British Gas to benefit from our SEG export tariff, you are free to choose separate suppliers for your energy and export if you wish to.

On this tariff, we'll pay you a unit rate of 3.2 pence for every kilowatt hour (kWh) of eligible electricity you export to the grid.

Frequently asked questions

What if I'm a current Feed-in Tariff (FiT) customer?

A: Unfortunately, you can't be in receipt of an export tariff such as the Feed-in Tariff (FIT) scheme if you want to claim SEG payments, regardless of whether FIT export payments are made based on metered export or deemed export.

If you receive the Feed-in Tariff (FiT) today, you can opt out of receiving export payments under the FiT scheme and sign-up for the SEG tariff instead. It's a good idea to check your FiT rates, as well as other provider's SEG tariffs to decide what is best for you.


Can I have the Export and Earn Flex tariff if I have co-located battery storage?

A: Energy storage (i.e. co-located batteries) can receive export payments for electricity that's stored on your battery then fed into the grid if you have an eligible renewable energy source.

What if I change my installation set up?

A: You can install additional capacity to an eligible system. Please remember that if do this, anything over 5MW for solar photovoltaic (PV), wind, hydro or anaerobic digestion (AD) installations, or over 50kW for micro-CHP won’t be paid for.

If you add capacity to an existing SEG installation or have any questions, please contact us to let us know and discuss further.

Is there a limit to the amount of electricity I can export?

A: You can export an unlimited amount of electricity to the grid, but it can’t be any more than the amount of renewable energy your system can generate.

How do I know if I have the correct meters?

A: You'll need to have either a smart meter (first and second-generation smart meters also called SMETS1 and SMETS2 meters) or a separate export meter that's capable of recording export readings half-hourly.

If you're not sure, get in touch with your current energy supplier. They'll be able to tell you if you have a smart meter and if it's capable of reporting exports on a half-hourly basis.

How do I get an export meter reading?

A: How you identify the export meter reading you need to give us will depend on the type of meter you have. It's always best to check your meter specifications on how to do this for your type of meter.

If you have a separate export meter, your meter reading will be the number shown on the main display of the meter.  You may need to press a button for it to be displayed or illuminated.

If you have a smart meter, the export reading will be available on the display on the smart meter itself.  To access the export meter reading you will need to press the button, or buttons on your smart meter to scroll through the information on the meter display or select the export register from a menu system – it will depend on the type of smart meter you have installed.

Specific instructions may be available in a User Manual (if you have one), your electricity supplier should be able to help you if you have any problems locating the export meter reading.

When it comes to sending us your export meter reading, we’ll need your installation number, meter serial number, meter reading and meter reading date.  Please note, you do not need to provide an installation number when you give your opening export meter reading as part of your application. See how you gas smart meter works or how your electricity smart meter works for help.

Why is the SEG tariff separate from my existing import tariff?

A: The SEG tariff has been set up specifically so that you can export renewable electricity to the grid and is separate to your import tariff where you are charged for the electricity you import from the grid to power your business.

The flow of electricity into your business (known as consumption) and from your business (known as export) are measured separately by your smart meter. We'll use the export meter readings you give us to pay you for your exported electricity.

You don't need to have an import tariff with us to qualify for our SEG export tariff.

What if I want to cancel my SEG tariff with you?

A: If you decide to leave there's no exit fees, and you’re free to cancel the contract at any time. You can also switch to another supplier without notice or exit fee.

If you do decide to leave, you just need to provide a final export meter reading by email so we can issue your final payment and settle your account.
