MCS-Certified Solar Specialists
Solar that pays for itself. Then keeps paying.
Alliant Energy designs and installs solar systems for UK homes and businesses — built to deliver measurable returns from the first bill. Commercial payback from 2.9 years. Up to £12,000 in grants for homeowners.
What we install
Solar, storage, and EV — handled end to end.
Commercial Solar
Your roof should be an asset, not a cost. Fully-funded PPA, grants and tax-deductible finance — payback from 2.9 years.
Solar for Homes
Own your electricity — stop renting it from the grid. 30-year warranty, 0% VAT, and up to £12,000 in grants.
Battery Storage
Generate it. Store it. Use it when it costs most. Tesla, GivEnergy and Puredrive systems — no power goes to waste.
For businesses
Energy costs climb every year. Your roof can stop that.
The average UK business pays more for energy than it needs to. Commercial solar from Alliant turns your roof into a power source — cutting bills, generating income through grid export, and delivering a return that pays for itself in years, not decades.
We handle design, installation, grid connection and commissioning. Funding options include fully-funded PPA, government grants and tax-deductible asset finance — so you can start saving with no capital outlay.
- PPA, grants and asset finance — £0 upfront on qualifying installs.
- 15-year product warranty, 25-year performance guarantee.
- Installed with minimal disruption to daily operations.
- MCS-certified, NICEIC-approved, fully insured.
