Why now
Your Bill Climbs Every Evening. And You Have No Buffer.
Right now, your home draws everything it uses from the grid, the moment it uses it.
Evenings are the heavy shift.
Oven on. Kettle going. Lights, TV, washing machine, devices charging.
You have no buffer.
You buy every unit at the price the grid sets, on the day it sets it.
That's the gap a home battery closes.
Spend it
- Dinner on, lights on, devices charging
- Your home runs on stored power
- You buy less from the grid when demand peaks
Your battery fills up when power is cheapest for you.
In the evening, when usage spikes... your home runs on power you already banked.
Less reliance on the grid.
A buffer against future price rises instead of full exposure to them.
The right setup depends on your tariff and your home. That's exactly what the survey works out.

FAQ
Clear Answers Before You Book
The key checks before booking your free survey, visible without opening anything.
Do I need solar panels for a battery to be worth it?
No. On the right tariff a battery charges from the grid when your rate is low and runs your home in the evening. If you already have panels, it stores what your roof makes too.
Do I need to switch energy suppliers?
No. You can stay with your current supplier. The survey will tell you if a different tariff would do more for you.
What does the free survey involve?
It's remote. We look at your usage, tariff and property, and show you what a battery would do for your home. No one visits at this stage.
What happens if my home isn't suitable?
We tell you during the survey, and that's the end of it. No pressure to go further.
How long does installation take?
The survey confirms timings for your home before you decide anything.
Where does the battery go?
That depends on your home. The survey confirms the right spot before anything is booked in.
