What Is the Smart Export Guarantee?
The SEG is a UK government-backed scheme launched in 2020 that pays homeowners, businesses, and farms for the excess electricity their solar panels generate and feed back into the grid.
A typical home uses around 50% of the energy it generates — the other half is exported. With the SEG, that exported energy earns you money rather than being given away for free.
Earn From Excess Energy
Every kWh you export earns you money — payments are made quarterly by your chosen SEG supplier.
Up to £630+ Per Year
Combined with bill savings, the SEG significantly shortens your payback period to as little as 6-10 years.
Government-Backed Scheme
Introduced under the Energy Act 2013, the SEG is a legal requirement for large energy suppliers to offer.
Quarterly Payments
SEG payments are typically made quarterly — a reliable stream of income on top of your bill savings.
How Much Can You Earn?
Earnings depend on your system size, usage habits, and the tariff you choose. Based on a standard 4kW system exporting around 1,800–2,100 kWh per year:
| Tariff Type | SEG Rate | Est. Annual Payment |
|---|---|---|
| Low-end tariffs | 1.5 – 4p/kWh | £25 – £80 |
| Mid-range tariffs | 5 – 7p/kWh | £90 – £130 |
| High-end fixed-rate | 12 – 16p/kWh | £200 – £270 |
| Premium time-of-use (with battery) | 20 – 30p/kWh | £360 – £630+ |
Based on a 4kW solar PV system. Actual earnings depend on export volume, tariff, and energy usage.
How to Register for SEG Payments
Get MCS Certified Installation
Your solar panels must be installed by an MCS-certified installer. Paid For Solar connects you with certified local installers.
Get a Smart Meter
A smart meter is required to accurately measure your electricity exports. Most energy suppliers offer free installation.
Choose an SEG Supplier
Compare tariffs from Ofgem-listed SEG suppliers. You don't have to use your existing energy provider.
Apply & Provide Evidence
Submit your MCS certificate and smart meter details to your chosen SEG supplier to open your export account.
Start Earning
Once your account is active (typically 2–4 weeks), you'll start earning quarterly payments for your exported energy.
Maximise Your SEG Earnings
Choose a Higher Tariff
Shop around — SEG rates vary significantly. Switching to a better tariff can increase annual payments by hundreds of pounds.
Add Battery Storage
Battery storage lets you access premium time-of-use tariffs of 20–30p/kWh, dramatically increasing what you earn.
Use Energy Smartly
Run high-energy appliances (dishwasher, washing machine) during peak solar generation to maximise self-consumption.
Different SEG Suppliers
You can use a different supplier for SEG exports than for your electricity. This gives you complete freedom to find the best deal.
Review Annually
SEG tariffs change. Reviewing your agreement annually ensures you're always on the most competitive rate available.
