Green Electricity Tariffs in NI: What to Check

Published on 3 June 2026 by Wee Switch NI Team. Last reviewed 3 June 2026.

How to look beyond the label on green tariffs and compare price, evidence and supplier claims.

A green tariff can be a good choice, but the wording matters. The electricity reaching your home still comes through the shared grid, so the key question is how the supplier backs up its renewable claim.

A green tariff is not automatically expensive, and a standard tariff is not automatically poor value. Compare the annual cost first, then weigh up the renewable claim and supplier transparency.

The strongest green tariff for you is one that is affordable, clearly explained and backed by evidence rather than vague wording.
