Is a green tariff worth it?

A green tariff does not save you money — you pay the same rate as standard. It supports renewable generation indirectly through certificates (REGOs). For genuine personal impact and savings: solar panels are far superior.

Can I have both solar and a green tariff?

Yes — but unnecessary. Your solar generates clean electricity directly. A green tariff on top adds cost without additional benefit. Use the money on a better tariff (Octopus Go/Flux) or a battery instead.

Solar vs green tariff — Solar generates free electricity. A green tariff just buys someone else's renewable electricity at full price.

Is a green tariff as good as solar panels?

Solar panels are dramatically better than a green electricity tariff. Solar generates YOUR OWN electricity for free (after payback), saving £580-£1,100/year. A green tariff buys renewable electricity from the grid at the SAME PRICE as standard electricity — no savings, just a different source label. Solar: saves money + generates clean energy. Green tariff: costs the same + claims clean energy. For genuine impact: install solar.
