A cheaper price per kWh can still produce a higher yearly electricity bill. Use the complete guide to compare like with like.
Compare the full annual cost
Use the same household consumption for both quotes. Multiply annual kWh by the unit rate, then add fixed charges and applicable extras and subtract eligible discounts. Check which taxes and network costs are already included to avoid double-counting.
Work through the €105 versus €120 example
At 3,500 kWh a year, a unit price three cents lower saves €105. A standing charge €10 higher per month adds €120 a year. In this illustration, the otherwise equivalent offer costs €15 more overall. These are fictional figures, not actual supplier offers.
Check the contract risks
Review introductory discounts and expiry dates, fixed or variable rates, time-of-use assumptions, included charges, minimum terms and exit conditions. Record how the price can change and verify current terms with the supplier.
