Thousands of Bulb customers will have their energy accounts moved over to Octopus Energy by the end of this month.
Octopus Energy announced it was going to take over the collapsed energy firm Bulb at the end of last year which saw it take on an extra 1.5million energy customers.
As of now, Octopus said that around 90% of customers of 1.35million accounts have been moved over from Bulb.
By May 31, the supplier expects around 95% of Bulb's old customer base will be switched over.
This means around 75,000 Bulb customers will be moved over before June.
Octopus told the Mirror that the remaining accounts to be moved over are "more complex" such as those with export tariffs as well as import tariffs.
This means it needs more time to move these accounts over.
For Bulb customers still waiting to move, you do not need to do anything.
Octopus will contact you over the next few weeks to let you know your account is being moved over.
You will usually receive an email from hello@octopus.energywhich will explain everything you need to know and will allow you to set up your new Octopus energy account.
This means you will not need to contact Octopus about your move, and in the meantime, you should continue to manage your bills and payments on Bulb's website.
You should also contact Bulb's customer services team as Octopus support staff will not have access to your account information yet.
Octopus has confirmed that the switch will not interrupt your supply, bills or meter.
An Octopus Energy spokesperson told the Mirror: "We're delighted to have already moved 90% of Bulb customers to our new system in just three months – a record for the industry.
"When customers switch, they are immediately ready to go with their Octopus Energy account and app.
"In the meantime, prices are the same for both Octopus and Bulb, and the Bulb team are continuing to support their customers until they’ve moved across to Octopus."
Bulb collapsed into administration in November 2021 and was one of the largest energy firms to go under during this time.
In 2021, a total of 28 energy firms went under due to rising wholesale gas prices.
Bulb, however, went into "special administration" which allowed it to operate as normal through being funded by the Government.
Overall, the Government put £4billion into Bulb.
Octopus Energy has been directly contacted by The Mirror for comment.
