Key answer

Start with the information on your quote

Use the annual cost calculator for one offer. Use the quote comparison tool when two providers have supplied rates. These are estimates for decision support, not live supplier quotations.

Keep the evidence and assumptions behind every quoted total.

Choose a tool

The annual cost calculator combines consumption, unit rate and standing charge. The quote comparison tool applies one consumption figure to two offers and shows the estimated difference.

Neither tool assumes an omitted fee is zero. Add known annual costs and keep a note of variable or unknown elements before making a decision.
