Battery savings estimator

Could a home battery cut your electricity costs?

Answer a few simple questions. We’ll estimate how much electricity a battery could shift to lower-cost periods and give you an indicative saving and payback.

Step 1 of 7 About you

First, a little about you

We use this to personalise your estimate. Nothing is sent anywhere until you choose to request an assessment.

What are you paying now?

Use electricity costs only if you have a combined gas and electricity bill.

An estimate is fine. We can tighten this using a bill or smart-meter data later.
Usually shown on your electricity statement. If left blank, we estimate usage from your bill.
Enter pence per kWh. If unsure, leave the example rate and we’ll flag it as an assumption.

How does your tariff work?

A battery does not create cheap electricity by itself. The saving depends heavily on whether you can charge it at a lower rate.

Leave blank if unknown. The result will show that tariff confirmation is needed.

These details affect which tariffs and optimisation options may be available.

When do you use most electricity?

This helps us estimate how much higher-cost electricity a battery could realistically replace.

Which battery are you considering?

If you’re unsure, choose “Recommend one” and we’ll use the 15 kWh package for the first estimate.

Joulen / flexibility income is not included in this result.
That is deliberate. Any additional flexibility-market income should only be added once GridPivot has confirmed the exact commercial terms, eligibility, compatible equipment and whether any revenue is guaranteed or variable.
Important: This calculator provides an illustrative estimate only and is not a quotation, guarantee of savings, guarantee of payback or financial advice. Actual results depend on electricity consumption, the customer's tariff and eligibility, future energy prices, battery performance, installation conditions, battery degradation, system availability and any third-party optimisation or flexibility services. Installation of a battery does not itself create access to cheaper electricity. Final savings and system suitability must be confirmed following review of the customer's electricity data, tariff and site.
