What are our explainers?
Plain-English guides to home energy technology. No jargon, no sales pitch, just clear answers to how solar, batteries, heat pumps, insulation and EV charging actually work.
Solar energy explained
How solar panels convert sunlight into electricity, what affects output, how inverters work and the basics of connecting a solar system to the grid.
Battery storage explained
How home batteries store and release energy, the difference between AC-coupled and DC-coupled systems, cycle life, degradation and what kWh actually means.
Heat pumps explained
How heat pumps extract renewable heat from air or ground, what coefficient of performance means, why they work in cold weather and how they connect to your heating system.
Home insulation explained
How insulation reduces heat loss, what U-values mean, the difference between conduction, convection and radiation, and why fabric-first matters.
EV charging explained
How electric car charging works at home and away, what kW and kWh mean for charging speed, how smart charging saves money and what V2G could mean for the future.
Energy tariffs explained
How UK energy pricing works, what standing charges, unit rates and price caps mean, how time-of-use tariffs work and how the Smart Export Guarantee pays you for surplus generation.
The UK electricity grid explained
How the UK electricity grid works, where power comes from, how supply and demand are balanced, what the carbon intensity tracker shows and how distributed generation is changing the system.
Carbon footprint & net zero
What your home’s carbon footprint is, how it is measured, what the UK net zero target means for homeowners and how each upgrade contributes to decarbonisation.
Glossary of energy terms
A plain-English glossary of the technical terms used across the site, from ASHP to zero-carbon, so you never get lost in jargon.
