# Clearsight Energy

> Clearsight Energy helps UK businesses compare, understand and secure better energy contracts. We combine commercial energy price comparison across the suppliers on our panel with a managed procurement service for gas, electricity and water. We work with small and medium businesses, commercial landlords and managing agents, and multi-site operators in retail, hospitality, logistics and industrial sectors. The approach is education-led: we explain how contracts work, what drives pricing and where control sits, so the focus is on long-term value and informed decisions rather than quick switches. We are paid by supplier commission; the page 'How we make our money' explains the model.
