Case StudyCase Study: How This High Electricity Usage Household Slashed Their Bills

Published on: 3 June 2025

WHAT THEY DID

This family in Cambridgeshire approached Brimstone Energy, one of our high quality approved installers, to help them add solar and storage to their home.

The household has high electricity consumption, with an EV, hot tub, induction hob and medical devices for their son.

Matt Hilton at Brimstone recommended 18 solar panels on their westerly facing roof, and a 15kWh Powervault battery. In combination with Octopus’s EV tariff with a rate of 7p/kWh overnight, and a 15p/kWh export tariff, the family have already reduced their weekly electricity bills from £60 to just £20/wk.
