Illustrative worked example

This worked example uses invented household figures to demonstrate how future case studies and recommendations will be presented. It is not evidence from a real household, and its costs, savings and performance figures must not be used for a purchasing decision.

Worked example

A new build with a heat pump and an EV — should they add solar and a battery?

An invented four-bedroom new build with an air source heat pump, one electric vehicle and no solar. Every figure below is made up to demonstrate how a case study will be presented once real, consented households are involved.
