The solution: Balance price with service quality, supplier stability, and contract fairness
Mistake 2: Not Checking Supplier Financial Stability
The error: Ignoring supplier financial health and stability indicators

The error: Focusing purely on rates without considering service quality and responsiveness
Why it’s costly: Poor service leads to billing issues, unresolved disputes, and wasted management time
The solution: Research customer reviews and service reputation before signing

When should small businesses switch suppliers?
Small businesses should strategically switch business energy suppliers UK:
4-6 Months Before Contract Expiry – Begin procurement allowing adequate comparison time. Business energy suppliers UK provide best rates for future-dated contracts. Early action prevents expensive auto-renewals.
Never Auto-Renew – Auto-renewal rates typically cost 30-50% more than negotiated contracts. This single mistake wastes more money than any other energy decision.
When Consumption Changes 20%+ – Business growth, shrinkage, or operational changes may warrant reviewing whether current supplier and contract remain optimal.
Poor Service Persists – If billing issues, customer service problems, or dispute resolution failures continue, consider switching even mid-contract if savings outweigh exit fees.
Market Prices Drop Significantly – When wholesale energy falls 20%+ below your contracted rates, calculate whether switching savings exceed any early exit fees.
Timing Tips: Start procurement at contract month -6 | Set renewal reminders at -12, -6, and -4 months | Compare 5-8 business energy suppliers UK minimum | Verify financial stability before signing | Negotiate exit fees down where possible.
Kilowatt Energy handles entire switching process for small businesses, typically delivering 15-25% savings through expert timing and negotiation with business energy suppliers UK.
