Five technologies, one home

Solar panels, battery storage, heat pumps, insulation, EV chargers, each technology or a combination of technologies will suit different buildings. Looking at your home and your lifestyle first, shows which of them or which combinations are worth considering.

Each technology operates under specific structural, electrical and spatial requirements. Check these before comparing costs or savings.

Panels convert daylight into electricity and need a roof with a suitable direction, pitch and shading. The report notes how much of your household use they could cover.

Heat pumps move heat from outside air or ground into your home. They need space for an outdoor unit and work best where heat loss is low.

Loft, wall and floor insulation reduce heat loss. Fabric efficiency shapes how well any heating system performs, so it is often assessed first.

A home charger needs a suitable parking space, a dedicated circuit and a supply that matches your electricity use. Charging costs vary with your tariff.

Batteries store surplus solar power or cheaper overnight electricity for later use. Their value depends on your household tariff and daily usage pattern.
