EDF Solar Tariffs Explained: SEG Rates, GoElectric and Empower for Solar Owners (UK 2026)

EDF is one of the UK’s largest energy suppliers and offers a range of tariffs relevant to solar panel owners, including Smart Export Guarantee (SEG) payments for exported electricity and specialist tariffs for electric vehicle and heat pump owners. As a major supplier with over 150,000 customers, EDF is legally required to offer SEG, and their rates have shifted over the past year – the headline export rate has been as high as 24p per kWh, before being reduced to 18p in March 2026.

For solar owners, EDF provides both export tariffs to earn from surplus generation and import tariffs that can complement a solar installation. Their GoElectric range is competitive for households combining solar with EVs or heat pumps, offering some of the cheapest overnight rates on the market and the longest off-peak window (7 hours, 11pm-6am).

This guide covers EDF’s current solar-related tariffs as of May 2026, how their SEG compares to competitors, their time-of-use options, and whether EDF is a good choice for solar panel owners.

EV Tariff Range

As of April 2026, EDF’s 7-hour off-peak window is the longest of any major UK EV supplier – Intelligent Octopus Go offers 6 hours, British Gas EV Power 6 hours. Combined with a 6.99p rate, GoElectric became the cheapest overnight charging on the market. EDF’s GoElectric tariff page has the live rates and current sign-up details.

Summary

EDF’s 2026 solar offering is more competitive than it has been for years. The 6.99p GoElectric off-peak rate is currently the cheapest in the market, with the longest off-peak window at 7 hours. The 15p Export 12m fixed SEG rate matches British Gas and OVO and beats Octopus Outgoing Fixed (12p) for households willing to be EDF import customers.

For households buying solar through EDF directly, the Empower + Export Exclusive bundle is genuinely interesting – the combination of zero standing charge and 18p export creates a path to very low or zero net electricity bills for typical UK consumption with a battery. The catch, as with all bundle offers, is that you commit to EDF as your installer, which limits your ability to shop installer quotes against the open market.

For households who already have solar from another installer, the practical play is to take EDF for import (especially GoElectric if you have an EV) and choose the highest-paying SEG provider for export – that might still be EDF Export 12m at 15p, but Octopus Outgoing Fixed at 12p is also worth considering for the no-import-tie flexibility, and E.ON Next Export Premium at 17.5p is worth a look if you have an E.ON-installed system.

Always check current rates before committing – EDF has updated their SEG and import tariffs several times over 2025-2026, and what’s competitive today may shift again. Compare with at least Octopus Energy, British Gas, E.ON and one independent before deciding.
