The UK's Advertising Standards Authority ruled in September 2026 that a StopWatt advertisement's electricity-saving claims were unsubstantiated and misleading. This ruling applies to the advertisement examination and should not be misrepresented as a direct laboratory test of every individual unit.

When assessing a product, check whether its claims are supported by an independent organization and whether the results are relevant to ordinary household electricity billing.
