Why Out of Contract Tariffs Are Expensive Energy suppliers often impose premium rates on out-of-contract tariffs for two key reasons:
Perceived risk – without a formal agreement, the supplier sees your business as unpredictable, and charges accordingly. Incentive to act – higher costs are often used to push you toward signing a new, fixed-rate contract .
Unlike negotiated contracts, these rates are not tailored to your usage or business type… so you’ll almost always be paying more than necessary!!
The Importance of Renewing or Switching Contracts Remaining on an out-of-contract rate for too long can drastically inflate your utility bills, something many small businesses can’t afford in our current economic climate.
✅ A new fixed or flexible deal ensures:
Predictable monthly costs 💷 Access to greener energy options 🌱 Protection from volatile price swings 📉📈
