Pricing
How the pricing works
We won't quote BT Cloud Voice's prices here — they change with promotions, contract length and add-ons, and a stale figure helps nobody. Here's how ours works so you can compare it against whatever quote you're holding.
One price per user
From £19 per user per month. Add or remove people monthly — no fixed seat count and no line rental.
UK calls included
Calls to UK landlines and mobiles are in the price, so your monthly bill doesn't move with call volume.
Free to move over
Number porting and setup are free under the current offer. Extra numbers and desk phones are the only usual add-ons.
Full breakdown on our pricing page, or send us your current bill and we'll tell you what you'd pay with us.
