What this tool does

This interactive tool checks whether your business is paying expensive out-of-contract energy rates and shows you how much this could be costing you. It takes your contract details and current charges to work out if you're stuck on rolled-over or deemed rates that are typically much higher than fixed contracts.

The tool then gives you the exact steps to switch suppliers, including when to give notice and how long the process takes. This matters because out-of-contract rates can cost businesses hundreds or thousands of pounds more each year than they need to pay.

When to use it

Use this tool if your business energy contract has ended and you think you might have rolled onto your supplier's standard rates automatically. It's also helpful if you're not sure whether your contract is still active, or if your energy bills seem unusually high compared to what you were paying before.

The tool is particularly useful if you've been putting off dealing with energy procurement, as it shows you both the financial impact of delay and the practical steps to fix the situation.

How it works

You answer questions about your contract status, when it ended, your current unit rates, and your annual usage or spend. The tool uses this information to estimate whether you're on expensive out-of-contract rates and calculates roughly how much extra this could be costing you compared to current market rates.

Based on your situation, it then provides specific guidance on switching suppliers, including notice periods and timing considerations. Nothing you enter is saved, you don't need to create an account, and the tool reminds you to check official sources like Ofgem for detailed regulatory guidance.
