Warm Homes Loan Scheme
Eligible homeowners can apply through participating lenders to help pay for solar panels and battery storage.
How the scheme works
You must own a residential property in the UK and use an MCS-certified installer. The lender sets the interest rate, repayment terms and any additional eligibility requirements.
This is a loan that must be repaid. Scheme loans are separate from the iHeat finance options shown on this page.
Use your electricity when it suits you.
HiOne brings a hybrid inverter, modular batteries and energy management together in one system. Keep track of your energy with Hoymiles’ S-Miles monitoring platform.
No solar? Still an option.
With a suitable time-of-use tariff, charge at a lower rate and use stored electricity when rates rise. Savings depend on your tariff, usage and charging losses.
Explore battery storagePlan for power cuts
A backup installation can keep selected circuits or your home running. The circuits supported and backup duration depend on the design, battery charge and appliances in use.
Understand backupIs Hoymiles right for your home?
Start with your electricity use, then choose the storage and equipment to match.
Where it can help
- Use more of your solar. Keep surplus generation for the hours when you need it.
- Shift your electricity costs. A suitable tariff can let you charge at cheaper times.
- Plan for changing needs. The modular system offers different storage configurations. Discuss future additions when designing your installation.
What to consider
- More storage is not always better. Capacity should reflect what you can charge and use each day.
- Backup needs extra planning. Confirm the gateway, circuits and output required in your proposal.
- Your existing equipment matters. Panels, inverter, electrical supply and available space all affect the design.

Hoymiles HiOne FAQs
Questions about choosing and installing your battery?
What is Hoymiles HiOne?
HiOne combines a hybrid inverter, battery storage and energy management in one system. It stores electricity for use later, whether that comes from solar panels or the grid.
How much does a HiOne installation cost?
The price depends on your battery configuration and the installation work needed. Your iHeat proposal sets out the equipment, fitting and VAT, plus any agreed extras, before you order.
Can I use HiOne with existing solar panels?
We’ll check your panels, inverter and electrical setup before recommending a system. HiOne can also be included in a new solar and battery installation.
Will HiOne work during a power cut?
Backup requires a compatible Hoymiles gateway and a suitable installation design. We’ll confirm which circuits can be supported. How long they run depends on the battery charge and the appliances you use.
Can I add more battery storage later?
HiOne uses stackable battery modules. Future additions depend on the inverter and compatible battery configuration, so tell us about any expansion plans when we design your system.
How much could I save?
Savings depend on your electricity use, tariff, solar generation and battery capacity. We’ll discuss those details with you rather than promise a saving that may not suit your home.
