How we estimate savings - clearly and responsibly.
A real example: a typical four-bedroom home
This example is based on a four-bedroom family home in Surrey using around 5,666 kWh of electricity per year.
PowerBase charges overnight when electricity is cheaper, then supplies that stored energy during the day when prices are higher.
No solar panels are required for this example.

Before PowerBase
Average electricity bill: £171.36/month
Annual electricity cost: £2,056.32
Based on:
• EDF Standard Variable Tariff
• Typical daytime usage for a home of this size
With PowerBase
Optimised electricity bill: £52.16/month
PowerBase subscription: £59/month
Total monthly cost: £111.16
The Result
£60.20/month lower than before
That’s £722.40 per year savings — including the subscription.
How we calculate this
Our projections are based on:
• Household electricity usage
• Current UK tariff data
• Off-peak charging windows
• Smart battery optimisation modelling
We use conservative assumptions, industry modelling tools.
What this means in real life
• More predictable energy costs
• Reduced exposure to peak electricity rates
• Savings that start immediately

Savings vary by home, tariff, and usage.
