Executive summary
Energy is one of the most volatile costs UK businesses face. This report sets out the pricing landscape for 2026, the procurement strategies that control risk, and how contract choice affects the total cost of energy for a commercial user.
The businesses that manage energy best treat procurement as an ongoing strategy, not a one-off renewal decision.
Key findings
- Contract type materially affects both cost and risk exposure.
- Businesses do not benefit from the domestic price cap and face different market dynamics.
- Timing a renewal well can save more than switching supplier.
- Efficiency and demand management remain the most reliable cost levers.
Procurement strategy
Commercial energy buyers choose between fixed, flexible and pass-through contracts, each with a different balance of certainty and risk. The right choice depends on consumption size, risk appetite and cash flow.
Larger users can benefit from flexible procurement; smaller businesses often prefer the certainty of a fixed contract.
