The Smart Export Guarantee (SEG) allows Waltham Abbey homeowners with solar panels to earn money by selling surplus electricity back to the grid. All licensed electricity suppliers with 150,000+ customers must offer a SEG tariff, giving you a guaranteed market for your excess solar generation.
How the SEG Works
When your solar panels generate more electricity than your home uses, the surplus is automatically exported to the grid. A smart meter measures your exports, and your chosen SEG supplier pays you for every kilowatt-hour exported. Payments are typically made quarterly or annually, depending on the supplier.
Current SEG Rates
SEG rates vary between suppliers and change regularly. As of early 2026, typical rates range from 4p/kWh to 15p/kWh. Octopus Energy and Social Energy consistently offer competitive rates. Some suppliers offer fixed rates while others offer variable rates linked to wholesale prices.
Maximising Your SEG Income
A 4kW system in Waltham Abbey typically exports 50–60% of its generation without battery storage, earning £150–£400 per year at current SEG rates. Adding battery storage reduces exports but increases self-consumption — the financial benefit depends on the differential between your electricity import rate and your SEG export rate.
