- Wholesale market data from ICE Futures Europe and NBP indices

Transparency & Limitations
We believe in being upfront about what our data can and cannot tell you.
- Annual cost estimates assume Ofgem's Typical Domestic Consumption Values (TDCV)
- Actual bills vary based on your location, usage patterns, and payment method
- We do not receive commissions from any energy supplier — we are fully independent
- Some blog posts contain Amazon affiliate links and ads; we may earn a commission if you make a purchase
- Predictions are informed estimates, not guarantees — always check current rates
- Regional pricing variations exist; our figures represent national averages unless stated
