By regularly checking your available balance on your in-home display you'll be able to see when you're credit is getting low.
On the Secure in-home display you'll be able to see how much credit you have left and how long this should last you. You can also set a low credit alarm. You can find out how to do this in the user guide provided in your welcome pack. a copy of the user guide for your in-home display is also available in our library https://www.watkinsenergy.co.uk/library.html
We recommend that you top up as soon as you start to see your credit getting low. This will avoid the risk of having to use your emergency credit reserve, which has to be repaid, or even having your heating and hot water supply suspended.
