The rules in brief
Ofgem says suppliers choose the rate and the terms, but the rate must be above zero. Most want a smart meter that records exports and an MCS-certified system or an equivalent scheme. Octopus names MCS or FlexiOrb for its SEG tariff.
How to choose
Do not pick an installer for an export rate alone. A 4 kWp system exports only part of what it makes, so the gap between 4p and 12p is not worth a poor install. Our model uses 12p, the Outgoing Octopus rate, which flatters the numbers a little for anyone on a lower rate. Put your own figure into the estimator.
Questions people ask
Do I have to switch supplier?
Not for the lowest rates, which are open to anyone. The better rates need you to buy electricity or the install from that supplier.
Can I get SEG on plug-in solar?
Normally not. Suppliers want an MCS or equivalent certificate, and plug-in kits do not have one.
Do rates change?
Yes. Variable rates can move at any time. Fixed ones run for the tariff term, often 12 months.
