See Our Guarantees
Three guarantees. No exceptions.
Every scroll reveals a new promise. We stack them until doubt runs out of room.
10-Year Performance Guarantee
Every LiFePO₄ cell we install comes with a decade-long written promise: if any cell drops below 80% of its rated capacity, we replace it at zero cost to you. No call centres. No small print. Your postcode, our responsibility.
Written into every contract. No exceptions.
“Three winters in and the cells are still showing 97% capacity on the monitoring app. These lads mean what they say.”

Installation in 5 Hours or Your Survey Fee Back
We've timed 340 rural installs. The average door-to-done is 4 hours 22 minutes. If our team takes longer than 5 hours from first bolt to final sign-off, we refund your survey fee in full. That's not a marketing promise — it's a clause in your contract.
Written into every contract. No exceptions.
“They were done by half twelve. I'd made lunch and they were already packing the van. Absolutely no drama.”

Grid-Down Protection Certified
Every PowerHold system is independently tested and certified for islanding — the technical term for running your home entirely off stored power when the grid drops. Your house stays lit, your fridge keeps running, your pump keeps pumping. Your neighbours go dark. You don't.
Written into every contract. No exceptions.
“January storm took out the village for 11 hours. We didn't even notice until our neighbour knocked to charge her phone.”
