Provider Comparisons
Biz Phones vs other UK business phone providers
We've written these the way we'd explain it on the phone: who each provider genuinely suits, where they beat us, and where a small UK team is better off with us. Prices change constantly, so we point you at each provider's own site rather than quoting figures that go stale.

How the pricing works
We don't quote other providers' prices — they change with promotions, contract length and add-ons. 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.

FAQ
Switching provider and pricing, answered
No. The number is ported to the new provider while your old service stays live, so there's no gap in calls. Most single-number ports complete in around two weeks from the request.
