BT business phone alternative
If you are leaving a BT business phone product, the best replacement depends on which one you are on.

Which BT product are you on?
Each BT phone product has its own reason to move and its own switch. Choose yours.
BT Featureline
An exchange-based service on the old phone network. It is being switched off on 31 January 2027 and cannot be migrated automatically, so every line needs replacing.
BT One Phone
A mobile-first "one number" service that BT is withdrawing. Customers are being moved onto a new long contract, so it is worth choosing your own replacement.
BT Cloud Voice
BT's hosted phone system, usually on a multi-year contract with annual rises. A common reason to move is simply better value and AI call handling as standard.
Why businesses are leaving BT
The 2027 switch-off
The old phone network closes on 31 January 2027. Anything still on it, including Featureline, has to move to a cloud system first. Read the PSTN switch-off guide.
Long contracts and price rises
BT business phone products typically sit on multi-year terms with CPI-linked annual increases, which makes it hard to know what you will pay next year.
Products being retired
BT has been retiring older services and moving customers onto replacements they did not choose. A forced move is the ideal moment to compare on merit.

Common questions
What is the best alternative to BT for business phones?
The best alternative depends on which BT product you are on. If you are on Featureline you need to replace it before the 2027 switch-off; if you are on BT One Phone it is being withdrawn; if you are on Cloud Voice you may just want better value. In all three cases a UK cloud phone system such as Voxora replaces it, keeps your numbers with free porting and drops the long contract.
Can I keep my number if I leave BT?
Yes. You keep your existing business numbers by porting them to Voxora. Porting UK numbers is free and we run the transfer, so your old service stays live until the numbers move across and there is no need to cancel with BT first.
Will BT charge me to leave?
That depends on your contract. If you are still in a minimum term BT may apply an early-termination charge; if you are out of term it should not. We cannot pay BT charges, but we can help you check your end date and time your switch so you are not paying two providers at once.
