How smart Pay As You Go meter top-ups work

When you top up your smart Pay As You Go meter, the new credit is sent to your meter automatically.

It can take up to 40 minutes for the top-up to register on your meter.

What if my top-up isn’t showing on my smart Pay As You Go meter?

If it’s been longer than 40 minutes and your top-up still hasn’t gone through, you can use your 20-digit top-up code, also known as the Unique Transaction Reference Number (UTRN).

You can enter the code on an In-Home Display, Smart Energy Tracker or on the smart meter itself. See instructions for the different ways to top up using using a top-up code.
