Smart Export Guarantee (SEG) explained

The Smart Export Guarantee (SEG) allows homeowners with renewable energy sources to earn money by selling their surplus electricity back to the National Grid. This government-backed initiative, launched on 1 January 2020, transforms your home's generation into an active income stream, putting you in control of your energy and finances.

If you're generating your own power, Fuse Energy can help you manage your home's energy efficiently, whether you're importing or exporting. Discover how easy it is to switch and take control of your bills by clicking here.

What is the Smart Export Guarantee (SEG)?

Understanding the SEG scheme

The SEG is a UK government initiative that requires licensed electricity suppliers to pay small-scale low-carbon generators for the electricity they export to the National Grid. This means if your home generates more renewable electricity than you use, you can sell the excess back and get paid for it. The SEG is regulated by Ofgem, the Gas and Electricity Markets Authority, ensuring a framework for these payments. All licensed electricity suppliers with 150,000 or more domestic customers are mandated to offer at least one SEG tariff, fostering competition and choice for homeowners.

Key principles of SEG

The core idea behind SEG is to incentivise homeowners to invest in renewable energy technologies. By guaranteeing a payment for exported electricity, it helps make microgeneration more financially viable. This scheme replaced the previous Feed-in Tariff (FiT) scheme, focusing on market-led competition among suppliers to offer the best rates. The payments you receive are based on the amount of electricity your system exports, measured by a smart meter.

Who is eligible for the SEG?

Microgeneration technologies

To qualify for SEG payments, your microgeneration system must use a low-carbon technology. Eligible technologies include solar photovoltaic (PV), wind, hydro, micro combined heat and power (micro-CHP), and anaerobic digestion (AD). This covers the most common home renewable installations, particularly solar panels.

Capacity limits

Your installation must also meet specific capacity limits. The maximum capacity for eligible installations is 5 megawatts (MW), or 50 kilowatts (kW) for micro combined heat and power systems. For most domestic solar panel installations, this capacity limit is well within reach, ensuring that typical home systems qualify.

Certification requirements

Crucially, your installation must be certified under the Microgeneration Certification Scheme (MCS) or an equivalent scheme. This certification ensures that your system meets industry standards for quality and safety. Without it, you won't be able to apply for an SEG tariff. Always ensure your installer is MCS-certified and provides the necessary documentation.

Smart meter necessity

A smart meter capable of recording export readings is usually required for SEG. This meter accurately measures the amount of electricity you export to the grid, ensuring you're paid correctly. If you don't have one, your chosen SEG supplier will typically arrange for its installation as part of the application process.

How does the SEG work?

Exporting your surplus energy

When your microgeneration system produces more electricity than your home consumes, the excess is automatically exported to the National Grid. This surplus energy helps power other homes and businesses, contributing to the UK's renewable energy supply. Your smart meter records these exports.

SEG tariffs and payment rates

Each licensed electricity supplier offers at least one SEG tariff, with varying payment rates. These rates can be fixed or variable. Fixed rates offer stability, paying a set amount per kWh for a specified period. Variable rates, on the other hand, can fluctuate, potentially offering higher payments during periods of high demand or lower payments when demand is low. The average UK home uses around 2,700 kWh of electricity per year1, so every kWh you export can make a difference.

Receiving your SEG payments

Once you've signed up for an SEG tariff, your supplier will use the data from your smart meter to calculate your payments. Payments are typically made on a regular basis, often quarterly, directly into your bank account. The Fuse app allows you to track your exported energy and view statements, providing transparency over your SEG earnings.

Choosing the best SEG tariff

Comparing supplier offerings

With multiple suppliers offering SEG tariffs, it pays to shop around. Don't assume your existing energy supplier offers the best deal. Compare the payment rates, contract lengths, and any specific terms and conditions from different providers. Some tariffs might offer a higher rate but require you to be an electricity customer with them, while others are open to all eligible generators.

Fixed vs variable rates

Deciding between a fixed and variable rate depends on your priorities. A fixed rate provides predictable income, which can be reassuring. A variable rate might offer the potential for higher earnings if you can export more electricity during peak demand times, but it also carries the risk of lower payments. Consider your generation patterns and risk tolerance when making this choice.

Factors beyond the rate

While the payment rate is important, other factors should influence your decision. Look for suppliers with clear terms, reliable customer service, and easy-to-understand billing. A digital-first experience, like that offered by Fuse, can offer general convenience for managing your energy bills and statements. Accessible human customer support can also be invaluable if you have questions or issues.

How to apply for an SEG tariff

Step-by-step application process

1. Check eligibility: Ensure your microgeneration system meets the SEG criteria, including MCS certification and capacity limits.
2. Install a smart meter: If you don't already have one, arrange for a smart meter capable of recording export readings. Your chosen SEG supplier can often help with this.
3. Research tariffs: Compare SEG tariffs from different licensed electricity suppliers to find the best fit for your needs.
4. Apply: Contact your preferred supplier to apply for their SEG tariff. You'll typically need to provide details of your system, MCS certificate, and meter readings.
5. Provide meter readings: Ensure your smart meter is communicating correctly, or provide manual readings if required.
6. Receive payments: Once approved, you'll start receiving payments for your exported electricity.

What to expect after applying

After submitting your application, the supplier will verify your details and system certification. This process can take a few weeks. Once everything is confirmed, your SEG contract will begin, and you'll start earning from your surplus energy. Fuse empowers homeowners to turn their surplus renewable energy into a tangible financial reward through the SEG, offering a digital-first approach for managing your energy statements.

Managing your energy bills should be clear and easy to understand. Fuse Energy focuses on straightforward pricing, so you can see exactly what you're paying without unnecessary complexity. If you have a smart meter, you can view detailed usage data through the app or website, helping you understand how you can lower your bills. If you don't have a smart meter, Fuse Energy can upgrade your non-smart meter, completely for free. This can make it easier to track spending and make informed decisions about your energy use.
