Licensed electricity suppliers (SEG suppliers) are required to offer at least one SEG compliant export tariff to a generator with an eligible installation. A list of all SEG suppliers can be found on Ofgem’s website.
SEG suppliers decide exactly how they want their SEG export tariff to work in terms of its rate, type and length. However, the tariff must be greater than zero pence per kilowatt hour at all times.
As with tariffs for the purchase of electricity, there could be a variety of different SEG export tariffs available. SEG suppliers can compete and, if the tariff you are on becomes less attractive than another offered elsewhere, you can switch and export your electricity to a different SEG supplier.
For solar PV, wind turbines and micro-CHP installations you must use an MCS certified installer to install your system or an equivalent scheme. On completion of you install your installer will provide you with a MCS certificate. You can find an MCS certified installer here.
For all other installations, applicants will be asked to demonstrate that the installation is suitably certified. SEG supplier have discretion in how they satisfy themselves that the installation is suitably certified. You should speak to your chosen SEG supplier to understand exactly what information they need from you.
If you are receiving an export tariff as part of Feed–in–Tariff payments you cannot receive the SEG as well, and vice versa.
You can, however, receive the SEG if you are already claiming the Renewable Heat Incentive, Renewable Energy Guarantee Origins, or if you used a government grant to pay for the installation of the system.
You can extend your system and get paid the SEG, or have more than one technology installed and be paid the SEG for both systems, as long as you do not exceed the limit of up to 5MW (or 50kW for micro-CHP).
Where the export meter for an eligible installation also records electricity exported from a non-SEG eligible source, like a battery charged from a source other than the SEG eligible technology, the SEG supplier can choose to make SEG payments for none of the energy exported, or all of it. The SEG supplier may ask you to install extra metering, or they may estimate how much exported energy is eligible for you to receive payments on. It is up to the supplier what they do, and you may enquire with several suppliers to find out how they work before signing up.
