Tomorrow Solarplicity's customers will be transferred to EDF Energy, after Ofgem chose the Big Six gas and electricity supplier to take on the failed firm's customers.
If you're among the 7,500 people affected, EDF Energy will contact you soon to provide more details.
Your prices will change, although any credit you have built up will be honoured.
Read on to find out what you need to know about becoming a customer of EDF and what existing customers think of it.
Now you should wait for EDF Energy to contact you. It will do this in the 'coming days', according to Ofgem.
EDF said that it will send out welcome packs to customers once it has the details it needs from Solarplicity. These will include details of your new contract with EDF, including the price of your tariff.
You will move to an EDF Energy tariff, so your prices might be different to those with Solarplicity.
If you want to switch to another supplier, you will not be charged an exit fee.
If you were previously a Solarplicity customer but were transferred to Toto Energy, this does not affect you. You will remain with Toto Energy, which says it has contacted all customers switched to it.
If you were in credit to Solarplicity, EDF Energy will honour the money owed to you. It says it will publish information 'shortly' on how to get a refund.
If you switched to another company and are waiting for a refund of your credit, then it will be paid to you, although you'll need to wait until EDF has the information it needs from Solarplicity.
You will still need to repay any money you owed to Solarplicity. EDF Energy will not collect this, and Solarplicity's administrators will get in touch.
If Solarplicity paid your feed-in tariff, you will need to approach a new FIT licensee (supplier) to continue to receive the payments.
Energy regulator Ofgem appointed EDF Energy to take on Solarplicity's customers after a competitive process.
Ofgem says that the process is to get the 'best deal possible for customers'.
EDF Energy scored an average three stars across the board in our survey, including for its customer service online and on the phone, how it handles complaints and value for money.
