Once you’ve completed the sign up process over the phone or online, you’ll get a welcome pack via email which confirms your tariff, your expected supply start date, your personal and supply details and your cancellation period.
You will have 14 calendar days to change your mind about a move to Boost (from the day you sign up). Just let us know (by email or by phone) if anything confirmed in your welcome pack needs changing, or if you want the switch to Boost cancelled.
If you have smart meters (here’s a topic
which advises you how to check), you’ll be going onto PAYG+ or Smart PAYG Standard. Info on the key differences between them here.
For PAYG+ you will be sent your one energy payment card in the post around your supply start date. For Smart PAYG Standard you’ll get a card for electricity and a card for gas around the same time.
Your old supplier will put the meters into a non disconnecting ‘credit’ setting the day before your switch date. We will then take over the meters.
For Smart PAYG Standard, it takes us up to 72 hours from your supply start date to link up your top up cards with your smart meters. Your In Home Display and screen 7 on the meter’s display will show a credit balance when this is done.
For PAYG+ it will also take us up to 72 hours from your supply start date to set up your online account. We’ll email you to confirm your login details once this is done. Until then your meters will stay in that non disconnecting ‘credit’ setting.
