For businesses
Why Businesses in Lancashire Are Switching to Solar
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.
