Running a business in London means juggling a lot, client meetings across the city, staff working from home some days and the office on others, and customers who expect to reach you quickly however they call. As a trusted VoIP London provider since 2004, we give your team a dependable way to handle every call, wherever they are that day.

Missed calls cost you business, whether it’s a new enquiry or an existing client chasing an update. Ours brings reliable call forwarding, voicemail sent straight to your inbox, and clear video conferencing, so nothing falls through the cracks while you’re focused on running things rather than answering the phone.
Cloud telephony strips out the cost and hassle of a traditional phone system, no on site hardware to maintain, no engineer call outs, and no separate contracts for lines, handsets and voicemail. Everything runs through one straightforward monthly plan, so you always know what you’re paying for and why, one reason business VoIP has become the natural choice for London companies moving away from ageing landline contracts.
London’s working patterns make this even more valuable. With teams split across a City office, a Canary Wharf desk and a growing number of days worked from home, a phone system tied to one building stops making sense. A cloud system follows your people rather than your postcode, so a call answered in Holborn on Monday can just as easily be answered from a spare room in Croydon on Friday, with no difference to the person calling in. For businesses paying London rents, that flexibility to scale a team up or down without touching a single phone line or cable is often worth as much as the call quality itself.
UCaaS stands for Unified Communications as a Service. It replaces separate phone systems, video platforms, and messaging tools with one cloud environment at a single monthly price per user. The unified communications London businesses benefit from most is a system that removes the cost of managing several independent subscriptions.
CCaaS stands for Contact Centre as a Service. It adds skills based routing, live wallboards, workforce management, and AI coaching on top of your core platform. Our system runs both on a single shared infrastructure, so voice, messaging, video, and contact centre interactions all share one analytics engine.
Every call is delivered in HD audio using the Opus codec, noticeably clearer than legacy system quality. Video conferencing comes with screen sharing, meeting recording, and joining through a browser so clients and colleagues connect from any device without installing additional software.
Persistent messaging channels cut out the scattered email threads and missed instant messages that slow teams down. Messages, files, and conversation history are searchable and sit alongside your calls on the same platform, so nothing important gets buried in someone’s inbox.
A visual console gives reception teams a clear screen for managing multiple inbound calls at once. Queue depth, agent presence, hold, transfer, and call park are all controllable from a single view.
Every call is transcribed in real time and a structured summary is produced automatically when it ends. Speech analytics surface sentiment trends, recurring customer questions, and agent performance patterns across your full call volume.
An AI virtual agent handles inbound calls at any hour without a human operator. It understands natural language, completes tasks such as appointment bookings and account queries, and passes the caller to a live agent with the full conversation context already transferred.
When a caller needs a specific person rather than the next available agent, Expert Connect routes the call based on account history, query topic, and current availability. A law firm in Holborn can connect a client directly to the right fee earner without the caller pressing through a phone menu.
The platform connects to Microsoft Teams, Salesforce, HubSpot, Zendesk, Dynamics 365, Google Workspace, Zoho, and Slack. When a customer calls, their record is already on screen. When the call ends, notes sync automatically.
When you call 020 8159 1900, you speak to a person who knows your account. No overseas call centres and no automated queues for billing or technical issues. The same team delivering business communications London organisations rely on has been doing so for over two decades..
For London businesses in financial services, legal, healthcare, and media, communication security is not optional.
The platform holds ISO 27001 for information security management, SOC 2 Type II for operational controls, and Cyber Essentials Plus, the UK government endorsed standard assessed annually by an independent body.
All voice traffic uses TLS encryption and SRTP media security. STIR/SHAKEN authentication digitally signs every outbound call from your 020 number so recipients see it as a verified call rather than an unknown caller on their screen.

The features available through your plan depend on the package that suits your business. Our team will confirm the right combination before you commit to anything.
Whatever stage you’re at with your current setup, our team can talk you through the right business phone system in London for your business. Call 020 8159 1900 or contact us online.
Every business phone system in London we supply includes full contact centre capability from day one. Whether you run a small service desk in London city centre or an energy business spanning several sites across the south of England, the tools are the same.
With over two decades of experience, your business is in the best hands to deliver your communications needs.
No more complicated setup or engineer callouts. Most systems are fully programmed and live within two hours of your order being confirmed.
Whether you are UK based or elsewhere in the world, our HD platform gives you a presence wherever you need it.
Every system goes live in five steps, managed entirely by our team. There is no engineer visit to your London premises and no disruption to your working day.
Step 1. Discovery Call
Your London account manager covers your current setup, team size, sites across the city and the south of England, and the applications you rely on. Every question is asked at this stage so your configuration is complete before anything ships.
Step 2. Remote Build
Your system is configured and fully tested before delivery. Call routing, hunt groups, IVR menus, and integrations with Salesforce, Teams, Zoho, or whichever tools you use are all working before your handsets leave the warehouse.
Step 3. Plug and Register
Phones arrive at your London premises fully registered. Plug them into your router and they come online immediately. No cabling and no disruption to your team.
Step 4. Your 020 Number Carries Across
Your existing 020 number transfers to the hosted platform with no break in inbound calls during business hours. The process takes 10 to 15 working days, managed by our team throughout.
Step 5. Your Team Is Live
Teams using the app are typically live within two hours. Desk phone users follow within the same working day. Every user receives a short onboarding guide covering calls, voicemail, and messaging.
Our telephone system comes with a free iPhone or Android App plus a PC or Mac App too. This is great for working on the move or as a remote worker, as it allows you to make and receive calls via your mobile phone through the phone system.
When anyone calls your office number, if you are out and about, our App can answer as if you were sat at your desk, and likewise, you can make a call from anywhere in the world displaying as your office number instead of your mobile number.
Every business communicates differently, and London’s business population is about as varied as it gets. We work with financial and professional services firms in the City and Canary Wharf, where call recording and reliable uptime matter for compliance, and with legal practices around Holborn, where client confidentiality is non negotiable. We also support creative, media and technology teams around Shoreditch and Farringdon, along with retail, hospitality and property businesses right across the capital, from the West End to Croydon.
Wherever your postcode, our team can have a business phone system live within days of your order being confirmed. If your business needs a hand with connectivity too, we supply fibre broadband and leased lines to match, so your calls and your internet come from one team rather than two.
We’ve been taking care of London’s businesses and supplying them with communications for more than twenty years, and in that time we’ve learned that London businesses want two things above almost everything else: a system that just works, and a team who picks up when you call. Our VoIP business phone system typically goes live within an average of two hours, with UK based support on hand for the switch over and beyond. It’s also why we can call it award winning, the platform we run on has been recognised 14 times in the Gartner Magic Quadrant for Unified Communications as a Service, a rare and independently judged mark of reliability in this industry.
Call forwarding, call waiting, voicemail, 30 day hot storage call recording with cold storage available up to 10 years, and integration with the tools you already use like Salesforce and Microsoft Teams, so your calls get answered fast and your team doesn’t have to learn a new way of working on top of a new phone system. Whether you’re upgrading an old system or replacing one that’s letting you down, our specialists can talk you through what fits your London business best.
Choosing the right business phone system in London means working with a provider who understands how the city’s businesses actually operate.
Every business phone system in London we install comes with the same transparent pricing and ongoing support, whatever the size of your company, from phone systems for small businesses with a handful of desks to full contact centres handling hundreds of calls a day. Our pricing is straightforward with no hidden charges introduced after you sign up. Features are available across a range of plans and our team will confirm exactly what is right for your business before you commit to anything.
Contact our team for a same day pricing conversation, or call 020 8159 1900.
We want every client to have the best possible experience with us, both in the quality of what we provide and in the service you receive as an existing customer. That’s why we never charge for handset maintenance. As long as you have bought the handset from ourselves, and your handset model is still supported, you’ll get free software updates and a lifetime manufacturer’s warranty on it.
Please contact us for a list of supported models.
Every user can make and receive calls on their London business number from anywhere, using the free mobile and desktop apps. Outbound calls display your 020 number whether you are calling from the office, home, or overseas.

For over two decades, we’ve supported businesses through changes in technology, changes in the way people work, and now the move away from traditional landlines altogether. That consistency matters when you’re choosing who looks after something as basic as your phone line, you’re not just buying a system, you’re choosing a team who will still be answering the phone when something needs sorting five years from now.
Every customer gets the same proactive approach, we catch issues before they become problems, and if you’re moving your existing number across as part of the switch, that’s handled for you too. We support businesses the same way right across the UK, including our teams in Leeds, Bradford and Aberdeen.
The PSTN switch off is Openreach’s retirement of the UK’s copper telephone network, scheduled for 31 January 2027, and London’s older commercial buildings are more exposed than most. Many City and West End offices still rely on analogue lines for far more than phone calls: lift emergency phones, door entry systems, alarm panels and even some card payment terminals in older units often run over the same copper network as the desk phone. When the switch off happens, all of it stops working at once unless it has already been migrated.
We handle this as a single, planned move rather than a last minute scramble. Your phone numbers transfer across, your lift and alarm lines get assessed and migrated where needed, and your team keeps working throughout, typically with no more than a short, scheduled changeover window. Businesses in listed or older buildings across the City, Holborn and the West End should start this conversation now, availability for migrations before 2027 is tightening as the deadline gets closer.
Ratings only mean something when they come from people with no reason to be generous.
