Fixed: certainty at a premium
A fixed tariff locks your unit rate for the contract term. You know your cost per kWh for budgeting, and you are protected from spikes. The trade-off is that suppliers build a risk premium into the price, and you will not benefit if wholesale prices fall.
Variable: exposure with flexibility
Variable rates track the market and can drop quickly, but they can rise just as fast — and rarely come with meaningful notice. They suit businesses that can absorb short-term volatility or that expect to move premises within months.
Blend or stagger
Multi-site operators rarely need a single answer. Fixing the majority of load while leaving a smaller portion variable spreads renewal risk so you are never re-pricing your whole estate in one bad week. Staggering end dates across sites achieves the same thing with less complexity.
