A professional UK business number with AI call screening built in — so you project credibility to customers, keep your personal mobile private, and only speak to people worth speaking to.
When customers call your personal mobile, they have your private number permanently. You cannot change it without losing existing contacts, it looks unprofessional on listings and business cards, and you are contactable at any hour whether you want to be or not.
A dedicated UK business phone number solves all of this. It is the number you advertise publicly — on your website, your Google Business Profile, directories, and marketing materials. Your personal mobile stays completely out of it.
Pick a UK number with a local area code or non-geographic prefix. CallCenturion screens every call before forwarding genuine customers to your mobile — spam never reaches you.
Pick a local area code to build trust with nearby customers, or a non-geographic 08x number for a national presence. Numbers are available instantly — no waiting.
Customers see only your business number. Your personal mobile is never exposed, never on listings, and never in the hands of cold-callers.
Every inbound call is screened by the IsHuman Check™ before it reaches you. Spam and robocalls are blocked; genuine customers get through seamlessly.
Calls forward to your mobile, home landline, office VoIP, or any UK number. No new hardware, no engineer visits — it just works.
Every call is answered with a clear, professional greeting before screening — giving customers confidence they have reached a real business.
Already have a UK business number? You can port it to CallCenturion and add AI screening and forwarding to your existing number without changing it.
Any business that advertises a phone number publicly — from sole traders to small teams — benefits from separating business and personal calls.
From sign-up to your first screened call in under 10 minutes — no engineer, no contract.
Choose a UK area code or non-geographic prefix. Your number is provisioned instantly — no waiting period, no paperwork.
Enter the number you want genuine calls forwarded to — your mobile, a landline, or any UK phone. You can change this any time from your dashboard.
Set your screening sensitivity, business hours, and voicemail greeting. Outside your hours, calls go to professional voicemail automatically.
Add your number to your website, Google Business Profile, business cards, and any directories. It is your public-facing business contact from day one.
Spam and robocalls are blocked automatically. Genuine customers reach you on your mobile — your personal number never appears anywhere.
