Hosted phone system for UK businesses
Upgrade from outdated telephone systems to a flexible, cloud-hosted phone system that supports every call, device, and user—without the hassle of physical phone lines or on-site hardware.
What is a hosted phone system?
A hosted phone system is a cloud-based telephony solution that replaces the need for a traditional phone line or on-premises PBX hardware. Often referred to as a hosted PBX or hosted VoIP system, it lets you make and receive business calls using your internet connection—while all routing and system management are handled by your service provider.
Unlike a traditional phone system, a hosted solution is fully managed off-site. That means no maintenance, no complex setup, and no need for bulky hardware in your office. Whether you’re a team of 3 or 30, hosted phone systems are ideal for growing small businesses that need flexibility and reliability without the overhead.
How does a hosted phone system work?
Hosted phone systems work by transmitting your phone calls over internet protocol (IP) rather than the public switched telephone network (PSTN). When someone makes a call, it’s routed through your hosted PBX provider via the cloud and delivered to your mobile device, desk phone, or desktop app.
This means you don’t need a physical phone line or on-site phone system. Instead, all the functionality—call routing, voicemail, caller ID, and more—is delivered via a cloud-based platform. All you need is a strong internet connection and compatible devices.
What are the benefits of a hosted phone system?
Built for small businesses
Hosted phone systems give you enterprise-grade features without the complexity or cost—perfect for growing teams with limited time or IT resources.
Easy to set up and scale
Add users, phone numbers, or features in minutes. There’s no hardware to install and no need to wait for an engineer to make changes.
Lower your phone bills
Switching to hosted telephony helps reduce monthly costs by eliminating line rental and reducing the price of local and international calls.
Fully managed by experts
Your hosted telephone system is supported, maintained, and updated by your provider—so you can focus on running your business, not your phone system.
Work from anywhere
Take calls on your mobile phone, laptop, or desk phone. Hosted PBX systems work across locations, perfect for remote working or hybrid teams.
Futureproof your business
Hosted systems are regularly updated with new features, integrations, and security patches—so you’re always one step ahead.
Is a hosted phone system right for my business?
A hosted phone system is ideal for businesses that want high-quality features, less hassle and lower costs. Your entire phone system is managed in the cloud, giving you all the functionality you need—without the IT headaches.
Whether you’re running a busy office, supporting remote staff, or scaling your operations, a hosted solution lets you take calls on any device, from any location, with the same reliability and professionalism you’d expect from a traditional system.

Matthew Burton
I have used B4BC for almost 6 years now with my existing business & when it came to setting up my broadband / phone provisions for a new business I went straight to B4BC. These guys have exceptional customer service & take all the stress off your plate so you can focus on the million other things you need to take care of within your business. Could not recommend any higher!
Krishna Pariyar
B4BC has been the best system that I have used so far. They have solutions for every business phone system. The app works on both the desktop and phone, which have made operations convenient. Their support is great with response time and requests. And it’s really easy to reach the Account Manager through email, website chat support, phone and support ticket.
Dan Hall

Use B4BC for all our telecoms and its a breath of fresh air compared to who we used before. Recently moved our energy management through them and I’m equally as impressed. I wouldn’t hesitate for a second to recommend them.

Fortunately getting in touch with the team at Best 4 Business is very easy, there are no long call queues so you’re not left on hold for ages & you don’t have to go through lots of different options before being connected to an actual person. The issues I have experienced have been dealt with immediately.

Changing my entire office phone system and broadband is no small task, in fact it’s quite daunting. However luckily or really thanks to Google I found Best4 Business. These guys at B2B are just brilliant! I now have a new VOIP phone system, massively quick broadband, great phones, ongoing support and I have saved nearly £200 a month. Happy owner!!

Fantastic service from Best 4 Business Communications. I found this company online on Tuesday and within 2 days they had an engineer on site! We had been unable to get BT in for four weeks now.

Hosted phone system FAQs
Yes—hosted phone systems are designed with small businesses in mind. They’re cost-effective, easy to scale, and don’t require technical expertise to manage. Whether you’re working from an office, remotely, or a mix of both, a hosted telephone system gives you all the tools you need to stay connected and professional.
Most hosted phone systems can be set up in under 24 hours. Since everything is managed in the cloud, there’s no need for complex installations or engineers on-site. Once your phone numbers are ported and your IP phones or apps are configured, your system is ready to go.
A traditional PBX (Private Branch Exchange) is an on-premises phone system that requires physical hardware, cabling, and manual maintenance. A hosted PBX system, by contrast, is managed in the cloud and delivered over your internet connection. It provides the same core features—like internal extensions, call forwarding, and voicemail—without the need for on-site infrastructure.
Hosted PBX pricing typically depends on the number of users, features, and devices. Most hosted phone system plans are billed monthly and include access to features like call routing, voicemail, and caller ID, along with unlimited calling. Costs are significantly lower than maintaining a traditional PBX system and often include support and updates at no extra charge.
VoIP (Voice over Internet Protocol) is the technology that enables phone calls over the internet. A hosted system is the way that VoIP is delivered—meaning your phone system is managed and maintained in the cloud by a third-party provider. While VoIP refers to the method of transmitting calls, a hosted VoIP phone system includes the full package: infrastructure, support, and features.
A hosted phone system is a cloud-based telephone system where all call routing, voicemail, and management features are handled by your service provider off-site. Instead of relying on traditional phone lines or physical PBX hardware, hosted phone systems use your internet connection to make and receive calls—making setup faster, cheaper, and more flexible for small businesses.
