- PowerGuardian public data register — supplier score weighting
- Methodology version: v1
- Weights sum to 100% and are applied identically to every supplier.
What this figure cannot tell you
- Weighting is an editorial judgement about what matters to households, not an objective ranking of importance.
- Changing the weights would change every supplier's overall score, which is why changes require a version bump.
