How Solar Plug Scout researches claims
A claim is only as useful as its scope, source, checking date and limitations.
Published Reviewed

- Legislation, GOV.UK and DESNZ publications.

- Ofgem, MCS, Energy Saving Trust and applicable electrical guidance.
- Manufacturer documentation for product claims.
- Retailers for dated availability and price only.
- Reputable secondary analysis for context, never as the sole basis of a material regulatory or safety claim.

Changing facts
