Guides you can check, not just read
Three rules every HeatCost guide is written to.
Evidence-first guidance
Figures and claims are checked against official UK sources such as Ofgem, GOV.UK and the Energy Saving Trust before they are published.
Information review dates
Every guide carries its publication date, and time-sensitive guides — like the price cap — are revisited when official figures change.
