Filing Year For Action

Opportunity Green has filed a complaint with the UK’s Competition and Markets Authority (CMA) against Scotland Gas Networks plc (SGN) concerning its hydrogen heating trial in Fife, Scotland. The complaint alleges that SGN has made misleading environmental claims about hydrogen heating in its websites and promotional materials directed at local residents and prospective trial participants. Those claims present hydrogen as “clean burning”, “zero-carbon”, and capable of providing “green energy” to millions of homes.

The complaint argues that these claims omit critical information and conflate different types of hydrogen with very different environmental impacts. This risks misleading consumers about the emissions, efficiency, and feasibility of hydrogen as a solution for home heating.

This is particularly important given that the UK Government has yet to make its final decision on the role of hydrogen in home heating, expected in 2026. Misleading green claims risk shaping consumer choices and policy decisions based on inaccurate information. If the gas grid were repurposed for hydrogen, up to 85% of UK households could be affected, making truthful, evidence-based information essential to protecting consumers and the public interest.
