Key answer

Start with the current contract

Confirm the contract end date, termination requirements and whether the supply is already out of contract. Then obtain comparable written offers, select the suitable total cost and verify the first bill after the new contract begins.

A practical switching checklist

Give notice in the manner required by the existing contract. Do not assume that requesting a quote terminates the current agreement. If the business is moving premises, use the change-of-tenancy process and provide meter readings.

The new provider should confirm the planned start date and whether anything is blocking the transfer. Keep the old and new contract details available until final bills and opening readings have been checked.

  • Read the current termination and renewal terms.
  • Gather the MPAN, usage and a recent bill.
  • Compare written offers with the same assumptions.
  • Record the accepted rates, fees and start date.
  • Check final and opening meter readings and invoices.

When the supply is more complex

Half-hourly, multi-site and high-capacity supplies can require more data and coordination. Allow time to resolve meter information, capacity questions and contract alignment before the intended start date.
