Fuel Broadband has informed customers it is closing down and that their service is being transferred to the Post Office.
Customers have been assured there will be no change in the service they currently receive, as the Post Office uses the same supplier as Fuel Broadband.
Furthermore, people will not need to do anything in order to transfer to the Post Office, as it is working closely with Fuel to ensure a "seamless transfer of your service behind the scenes".
"The Post Office has been running its own broadband and phone service for well over 13 years and has over 460,000 customers," the Post Office said.
"We have fully launched fibre and are the fastest growing reseller in the United Kingdom."
The Post Office added that it is looking forward to having Fuel Broadband's customers on board and is working hard to ensure the migration process goes smoothly.
Services are scheduled to be transferred over at the end of July.
