How to switch

Here's a step by step process to switch from SmartestEnergy to a new supplier.

Switch at any time

If you’re out of contract or on deemed rates, you can switch at any time.

Check previous bills

Check you don’t have debt accrued from your existing contract, as this could prevent a switch.

Find a new deal

Ring around or use a comparison website to ensure you’ve found the best deal.

Agree a new contract

Your new supplier will apply to move your MPAN (Meter Point Administration Number).

Final billing

In the month following your change of supply date, you’ll receive a final bill showing your usage up to the date you left.

Switching to SmartestEnergy is simple and straightforward

  • No disruption to service

  • Thorough customer onboarding

  • Smooth transition to customer service and billing

  • We’ll tell your old supplier
