Electricity Supply Licence
Businesses supplying electricity to consumers in Great Britain require a Supply Licence from Ofgem.
How to register for the Smart Export Guarantee (SEG) to receive payment for renewable electricity you export to the grid. Covers solar PV, wind, and other small-scale renewables up to 5MW.
You can get paid for renewable electricity you send to the grid. You must use an MCS-certified installer and have a smart meter. Compare tariffs from different electricity suppliers to get the best rate.

If you generate renewable electricity - from solar panels, a wind turbine, or other small-scale renewables - you can be paid for the electricity you export to the grid through the Smart Export Guarantee (SEG).
The SEG replaced the Feed-in Tariff (closed in 2019) as the main payment mechanism for small generators. While export rates are typically lower than the old FIT, SEG provides ongoing income from your renewable installation.
You can apply for SEG if:
Your installation must be MCS certified to receive SEG payments:
How to get MCS certification:
If your installation wasn't done by an MCS installer, you may be able to get retrospective certification, but this involves additional cost and inspection.
Electricity suppliers with 150,000+ customers must offer SEG, but many smaller suppliers also participate. Key factors to consider:
The Energy Saving Trust and Ofgem maintain lists of SEG licensees for comparison.
If you're a larger generator and want to sell renewable energy guarantees:
Most small generators don't need a formal licence from Ofgem. You're typically exempt if:
Larger installations may need to apply for a generation licence. Check the exemptions before assuming you don't need one.
To export electricity, you need a grid connection agreement with your Distribution Network Operator (DNO). For small installations (under 4kW), your MCS installer typically handles this through the 'Fit and Inform' notification process.
Larger installations may need a formal connection application, which can involve:
Do I need to pay tax on SEG income? Income from SEG is generally taxable. For domestic installations, there's usually no tax if you use most electricity yourself. Business installations should account for the income. Check with HMRC or an accountant.
Can I get SEG if I had FIT? If you're already receiving FIT export payments, you cannot also receive SEG. If you were on FIT generation-only (no export payment), you may be able to apply for SEG export.
What happens if I move house? Solar panels are usually included in the house sale. The SEG contract typically transfers to the new owner, or you may need to notify your SEG licensee.
Can I store electricity instead of exporting? Yes. Installing a battery storage system lets you use more of your own electricity rather than exporting. This is often more valuable than SEG payments.
