Topping up with Smart Pay As You Go 

You can add credit to your meters any time you like, by topping up in your Bulb account or the Bulb app. Or you can go to your nearest PayPoint and top up in store with a payment card.

In your Bulb account and app

Go to the ‘Top up’ section of your Bulb account or app, where you can choose how much you want to add to each meter. 

After we’ve processed your payment, we’ll send the top up to your meter. This should just take a few minutes, and we’ll keep you updated by email and in your Bulb account.

In store at your nearest PayPoint

If you prefer to top up in store, you can top up at your nearest PayPoint using the top up cards we’ve sent you. There are separate cards for your gas and electricity meters. 
There is a minimum top up amount. This is:
  • £5 for electricity
  • £1 for gas
In the PayPoint store, ask the cashier to scan the barcode, or type in the long number underneath it. Once you’ve paid for your top up, make sure to keep your receipts.
It can take up to an hour for your top up to show up on the meter and in your Bulb account. If you can't see it on your meter after an hour, let us know.


If there's a problem with your top up

If Bulb can’t communicate with your meter, or your top up hasn’t worked, we’ll send you a 20 digit code to top up. This code is sometimes called a UTRN, and can be entered into your meter to add credit.

Check your top up history in your Bulb accountIf we’ve noticed an issue with your top up, you'll see a top up code.

The code will also be printed on your receipt if you topped up in store. 

If you can’t see a 20 digit number or the code doesn't work, get in touch and one of our team members will help you out.

Adding credit to your meter using a top up code

  1. Press the ‘A’ button on your meter twice to get to the ‘Add credit’ screen. 
  2. Press the ‘B’ button - you'll see the 'UTRN' screen, where you can enter your top up code. 
  3. To enter your code, press the ‘A’ button to scroll through the numbers 0 to 9, then press the ‘B’ button to move to the next digit.
  4. Once you’ve finished adding your code, hold the ‘B’ button down for at least 2 seconds to confirm. The meter will check the code to make sure you’ve entered it correctly, then will return to the home screen.

If the meter shows an ‘invalid payment code’ message, check the code hasn’t been used already, then try entering it again. 

If you run out of credit

When you’re getting low on credit, you’ll have access to £10 emergency credit. This makes sure your home has electricity or gas until you’re able to top up.

You’ll also have ‘Friendly Credit’ in case you run out of credit during a weekend or bank holiday.

If your meter runs out of credit, it’ll switch off. Find out how to switch your meter back on again after you’ve topped up.

Activating emergency credit

You’ll be able to access emergency credit when you’ve got less than £2 credit left on your meter. 

Follow these steps to activate your emergency credit:

  1. Press the ‘A’ button on your meter to turn on the screen.
  2. Press the ‘A’ button again. If your emergency credit is available, you’ll see the emergency credit screen - it’ll say ‘EmCr’ in the top right of the screen. 
  3. Press the ‘B’ button to activate your emergency credit. You’ll see a message confirming it’s been activated, and your meter will then go back to the home screen. 
  4. Pressing the ‘A’ button again will show you how much emergency credit you’ve got left.

You’ll need to repay your emergency credit in full before you can use it again.

Running out on weekends or bank holidays

To help make sure your home doesn’t run out of gas or electricity during an inconvenient time, your meters also offer ‘Friendly Credit’. 

This means your meters won’t switch off if you run out of credit on the weekend or a bank holiday.

You’ll have to pay back any Friendly Credit you use during this time.

To avoid your meters running out of credit, we suggest topping up regularly. With Smart Pay As You Go, we’ll let you know when you’re nearly out of credit.

Switching your meter back on 

If your meter has run out of credit, you’ll need to switch it back on after you’ve topped up.

Follow these steps to get your meter up and running again:

  1. Press the ‘A’ button. The whole screen should light up.
  2. Press the ‘A’ button. You’ll see a message saying ‘PP Press B for Elec’.
  3. Press the ‘B’ button. You’ll see a message saying ‘Enable supply?’
  4. Press and hold the ‘B’ button for around 2 seconds, until you see a message saying ‘Supply enabled’. Your meter is now online again, and the gas or electricity supply to your home will be restored.

Paying back debt on your meters

If your meter runs out of credit and you use up all £10 of emergency credit, your meter will start to build up debt. This debt can include your daily standing charge and any Friendly Credit you’ve used.

When you top up, you’ll have to pay back any emergency credit you’ve used before credit gets added to your meter.

You’ll pay back any debt you’ve built up on your meter by £1 every day, and a maximum of £5 a week per meter.
