When you top-up your Pay As You Go smart meter, the credit you've added should reach your meter automatically. This can take up to 40 minutes.

If that doesn't happen for any reason, or you need to add your credit more quickly, you can use a top-up code instead. It's a 20-digit number you'll get when you top-up your meter.

Where to find your top-up code

If you top-up online

You'll see your top-up code on the confirmation screen when you top-up online. It's worth making a note of this number in case you need it.

If you give us an email address when you're topping up, we'll email you a receipt with it on, too.

If you top-up in store

If you're going to top-up in a shop that offers PayPoint, you'll get a receipt that has your code on it.

It's important to keep hold of your receipt until you know the top-up has reached your meter.

How to use your top-up code

You can either enter the code into your Smart Energy Tracker, or directly into your smart meter.

Here's what you'll need to do if you're using your tracker:

  1. On the main menu, choose either ‘Electricity’ or 'Gas', depending on which meter you want to top-up.
  2. Select ‘Your account’, then 'Your top-ups' and finally ‘Top-up now’.
  3. Enter your top-up code by using the up and down arrows to select each number. Press ‘OK’ when you're ready to move to the next digit. Once you've entered all the numbers, press and hold 'OK' to submit the code.
  4. You'll now see a ‘Top-up accepted’ message on the screen. This will also show you the amount you've topped up and how much credit you have on the meter in total.
