About this grant

The Smart Export Guarantee (SEG) requires licensed electricity suppliers to pay homeowners for excess solar electricity they export to the grid. Rates are set by each supplier and vary typically from 3p to 15p per kWh. A typical 4kW solar system exporting 40% of its generation could earn £150–£500 per year depending on your supplier's rate and your usage pattern.

Who qualifies

Homeowners with solar PV panels (not renters)
MCS-certified solar installation
Smart meter installed (or willing to have one)
Solar system up to 5MW capacity (virtually all domestic systems qualify)

Who doesn't qualify

Renters without landlord permission and ownership
Systems without MCS certification
Homes without a compatible smart meter

How to apply — step by step

1

Get solar panels installed

Must be installed by an MCS-certified installer. Get your MCS certificate after installation.

2

Get a smart meter

Contact your energy supplier to install a smart meter if you do not have one.

3

Compare SEG tariffs

Check rates at ofgem.gov.uk/check-if-energy-price-cap-affects-you. Rates range from 3p to 15p per kWh.

4

Apply to your chosen supplier

Apply directly to your energy supplier for their SEG tariff. You can use any SEG-licensed supplier, not just your current one.

5

Get paid quarterly

Export payments are typically made quarterly based on smart meter readings.

Frequently asked questions

Can I combine SEG with other grants?

Yes — if you also qualify for the Boiler Upgrade Scheme or ECO4, SEG payments are on top of those.

Which supplier pays the most?

Rates change regularly. Octopus Energy and Ovo Energy have historically offered competitive rates — always compare at point of application.

What if I use all my solar electricity myself?

If your panels generate less than you use, you won't export anything and won't receive SEG payments. A battery can help maximise export.
