Sorry to hear this,
There could be a variety of reasons for why this has happened. One of the most likely explanations is that your gas might be supplied by an Independent Gas Transporter (IGT). If it is, it takes a bit longer (up to 12 weeks) for us to receive the necessary switch information to be able to bill your account. For more information on IGT’s, please take a look here: https://www.ovoenergy.com/ovo-answers/topics/all-about-switching/the-switching-process/what-is-an-independent-gas-transporter.html. Likewise if there's a holdup in being sent your electricity switch details this can also cause a delay in your billing.
Send us a message via Facebook, Twitter or email (email@example.com) for us to check this for you.
IGT's can now be treated in line with normal gas supplies, so the 12 week time frame above is no longer the case. Everything will go through just like a regular gas switch.
