SuppliersEditor's PickOur flagship independent ranking of UK energy suppliers for 2026, scoring service quality, value, billing accuracy, complaint handling and reliability so households can see which suppliers genuinely deliver and which fall short.
Standing ChargesA deep dive into the daily fixed fees on every UK energy bill. We analyse how standing charges vary by region and payment method, what they actually pay for, and whether the long-promised reform is any closer to reality.
Regional EnergyHow energy costs vary across the UK's 14 distribution regions — who pays the most, who pays the least and why. We map unit rates and standing charges region by region to reveal the postcode lottery built into UK energy pricing.
Home HeatingA practical, numbers-first look at UK heat pumps in 2026 — installation costs, real running costs versus a gas boiler, available grants and whether making the switch actually saves money for a typical home.
Solar & BatteryHome battery storage is booming, but does it pay? This report examines battery costs, realistic savings with and without solar, the impact of time-of-use tariffs, and how long a home battery really takes to pay for itself in 2026.
Energy PricesEditor's PickShould you fix your energy price in 2026? This report weighs the best fixed deals against the price cap, examines the risk of fixing at the wrong time, and gives a clear framework for deciding whether locking in your rate is worth it.
AI & EnergyEditor's PickArtificial intelligence and data centres are reshaping UK electricity demand. This report examines how AI-driven load growth affects grid capacity, wholesale prices and ultimately household bills — and what it means for the years ahead.
