✔ On average, households can expect to earn around £159 annually through this program.
What is the Smart Export Guarantee?
The Smart Export Guarantee is a government-backed initiative that allows renewable energy generators to sell any excess electricity back to national grid and get paid for it. This program has been in the market since 2010 under the name Feed-in Tariff, which has now been replaced with SEG. The idea behind introducing the SEG tariff in the UK is to encourage people to switch to renewable energy and go green.
The amount you receive for exported energy depends on the supplier’s rate, as each energy supplier has its own SEG rates for exported electricity. We will explore most of the available best SEG tariffs in the UK.
One important thing to keep in mind is that the rate you pay for electricity usage will not match the rate you receive for exporting excess electricity back to the grid through the Smart Export Guarantee program.

What’s The Best Smart Export Guarantee Rate?
Among all the companies offering the best SEG Tariff rates, Octopus stands out as it offers you up to 24p per kWh when exporting electricity back to the grid. Even if you aren’t an Octopus customer, you still have the opportunity to export your excess electricity back to Octopus at a reasonable rate of 4.1p per kWh, which is still higher than some other energy companies.
However, the best rate available to both customers and non-customers of solar panel homeowners is offered by Scottish Power at a rate of 12p per kWh, known as the SmartGen Tariff.
When inquiring about the lower rate for non-customers from Octopus, they explained that providing the same rate to customers of other suppliers isn’t feasible due to the significant effort and cost involved in setting up an export tariff.
How Much Money Can You Earn from The Smart Export Guarantee?
The money that an average solar panel owner can earn with the SEG Tariff in the UK is £160, assuming they have a three-bedroom house and a 3.5kW solar system.
However, every house is different, so the amount one can save varies. In this table, you will gain a generic understanding of how different houses with various sizes of Solar PV systems can earn from SEG Tariff rates.
SEG Annual Income Based on Solar Panel and House Size
| System Size | House Size | No of Panels | Estimated Annual SEG Profit |
| 2.1 | 1-2 bedrooms | 6 | £90-£100 |
| 3.5 | 3 | 10 | £155-£165 |
| 4.9 | 4 | 14 | £220-£230 |
| 5.5 | 5+ | 16 | £240-£250 |
How is SEG income Paid to You?
If you are associated with the same company that is also your supplier, in that case, you may receive a deduction in your monthly energy bills. In other cases, you will be paid through a bank transfer. The transaction depends on the rules and regulations of each energy supplier and how often they transfer your money for exporting energy back to the grid.
For instance, Scottish Energy transfers monthly, OVO every three months, while Shall Energy will pay you annually.
Is SEG Income Taxable?
If your solar array is situated on a residential property that you own or in close proximity to it, and you do not plan for your solar panels to generate a substantially larger amount of solar energy (typically defined as exceeding 20% of your home’s electricity consumption), then you might still be eligible for an exemption.
In such cases, you can categorize your Smart Export Guarantee (SEG) payments as both trading and miscellaneous income. As long as your combined income in this category remains below £1,000, you are not required to report it to HMRC (Her Majesty’s Revenue and Customs).
How Do You Qualify and Sign Up For SEG?
To qualify for the SEG Tariff in the UK, you must fall into one of the categories of energy generators listed below:
- Solar Panels
- Micro Combined heat and Power
- Hydro
- Wind Turbines
- Anaerobic digestion
The other necessary things for SEG sign-up and qualification are as follows:
- Your installation must have a maximum capacity of 5 MW. Without a combined heat and power installation, the upper limit does not exceed 50 kW.
- You are required to provide your Microgeneration Certification Scheme (MCS) certificate or an equivalent document.
- Ownership of an export meter is mandatory. Additionally, you will need to provide your SEG company with your export MPAN. If you’re uncertain about where to find your export MPAN, don’t hesitate to inquire with your supplier.
Can You Choose any Supplier for the SEG?
Yes! Homeowners owning solar panels can choose any energy supplier for the best SEG Tariff. You may receive minimal SEG rates, but you have the right to choose as you please. Some suppliers provide good SEG rates even to non-customers, such as Scottish British, Octopus, and E.ON. You can select the one that best suits your needs without any hurdles.
Do You Require a Smart Meter In Order To Receive SEG Payments?
It depends on the supplier’s requirements; some energy suppliers may ask you to install a smart meter before receiving the SEG tariff. In most cases, you might not be required to have a smart meter, but having one ensures accurate SEG tariff rates and eliminates the need for manual readings. There are some speculations that smart meters may become compulsory for SEG payments in the near future. Therefore, it is recommended to have one before applying for the SEG program.
Summary
The Smart Export Guarantee (SEG) Tariff presents an excellent opportunity to earn income by exporting surplus electricity back to the grid. Numerous energy suppliers participate in this program, each offering best SEG tariffs. Among the notable options, Octopus and Scottish Energy stand out, providing best SEG Tariff rates for exported electricity.
To access the SEG program, you must meet specific requirements, including furnishing Microgeneration Certification Scheme (MCS) documentation for your property and owning an export meter. These criteria ensure that you are properly equipped to participate in the program and receive fair compensation for your renewable energy contributions.
If you secure the best SEG Tariff rates from a supplier company, it offers a lucrative opportunity to both reduce your carbon footprint and earn money, with Octopus and Scottish Energy leading the way in offering favourable terms.
