Independent supplier intelligence. PowerGuardian is not affiliated with British Gas. Verified figures are sourced from published Ofgem, Citizens Advice and supplier data; estimated figures are modelled from PowerGuardian scoring and clearly labelled, and every module is built to connect to live data feeds as they become available. Always verify current pricing on the supplier's own website before switching.
Seeing estimated bills or odd charges from British Gas? Faulty meter readings — not the supplier — are often the cause. Check our guide to common smart meter problems and how to fix them before you judge their billing accuracy or decide to switch.
