If you’ve recently switched to Boost and this is your first time topping up as a Boost customer, you’ll need to start by registering your electricity key – and your gas card if you’ve got a traditional gas meter as well.
Remember, you should run down any existing credit on the meters as far as possible. If there’s credit left on either meter, you’ll need to ask your old supplier for a refund.
To register your new key and card, put them into the relevant meters for at least a minute. The gas card will beep to let you know when it’s registered.
Now you’re ready to top up!
We recommend you keep your receipt each time you top up, in case there’s a problem – for example, if the money doesn’t appear in your meter – and we need to investigate it for you.
These instructions are for traditional PAYG meters. Some energy customers have ‘smart’ PAYG meters, which you would top up differently.
This partly depends on where you’re topping up, as different shops have different minimum amounts. However, these are the usual minimum and maximum top-up amounts:
You can only top up in full pounds.
The maximum amount a card can hold is £249 and the most a key can hold is £250.
You can have up to £255 credit on your electricity meter and £249 on your gas meter. If you try to top up more than this, the credit in your key or card won’t transfer to your meter.
Don’t worry – it won’t be lost. It will just stay in your key or card until the credit balance in the meter is low enough to allow you to add the credit without exceeding the maximum amount.
